VDS treatment - treatment of vegetative-vascular dystonia. Reasons for a periodic or constant slight increase in body temperature Temperature 37.2 during the day at night 36.6

What are the reasons for the constant or intermittent slight increase in temperature at certain times of the day, in the evening or during the day? Why is an increase in body temperature from 37.2 to 37.6 ° C often observed in children, the elderly or pregnant women?

What does subfebrile temperature mean?

Subfebrile is indicated slight increase in body temperature before 37.2-37.6 ° C, the value of which, as a rule, fluctuates in the range of 36.8 ± 0.4 ° C. Sometimes temperatures can reach 38 ° C, but do not exceed this value, since temperatures over 38 ° C indicate fever.

Low-grade fever can affect anyone, but children and the elderly most vulnerable because they are more susceptible to infections and their immune systems are unable to defend the body.

When and how does subfebrile temperature appear?

Subfebrile temperature may appear in different moments of the day, which sometimes correlates with possible pathological or non-pathological causes.

Depending on the time at which subfebrile temperature occurs, we can distinguish:

Morning: subject suffers from subfebrile temperature in the morning when the temperature rises above 37.2 ° C. Although in the morning the physiologically normal body temperature should be below the daily average, therefore even a slight increase can be defined as subfebrile temperature.
After eating: After lunch, due to digestion and related physiological processes, the body temperature rises. This is not uncommon, therefore, an increase in temperature of more than 37.5 ° C is referred to as subfebrile.
Afternoon / evening: During the day and in the evening, there are also periods of physiological increase in body temperature. Therefore, an increase in excess of 37.5 ° C belongs to subfebrile temperature.

Low-grade fever can also occur different modes, which, as in the previous case, depends on the nature of the reasons, for example:

Sporadic: This type of low-grade fever is episodic, may be associated with seasonal changes or the onset of the menstrual cycle in women of childbearing age, or be the result of intense physical activity. This form causes the least concern, since, in most cases, it is not associated with pathology.
Intermittent: This subfebrile temperature is characterized by fluctuations or periodic occurrences at certain points in time. May be associated, for example, with physiological events, periods of intense stress, or an indicator of the development of a disease.
Persistent: a constant low-grade fever, which persists and does not subside throughout the day and lasts for quite a long time, is alarming, as it is closely associated with some diseases.

Symptoms associated with low-grade fever

Subfebrile temperature can be completely asymptomatic or be accompanied by a wide variety of symptoms, which, as a rule, become the reason for going to a doctor for diagnosis.

Among the symptoms that are most often associated with low-grade fever are:

Asthenia: Subject experiences a feeling of fatigue and exhaustion, which is directly correlated with increased temperature. It can be associated with infections, malignant neoplasms, and seasonal changes.
Pain: Along with the onset of low-grade fever, the subject may experience joint pain, back pain, or leg pain. In this case, a connection with the flu or an abrupt seasonal change is possible.
Cold symptoms: if, along with low-grade fever, a headache, dry cough and sore throat appear, then hypothermia and exposure to the virus may occur.
Abdominal symptoms: along with a slight increase in temperature, the patient may complain of abdominal pain, diarrhea, nausea. One of the possible causes is a gastroenterological infection.
Psychogenic symptoms: sometimes it is possible, together with the appearance of low-grade fever, the appearance of episodes of anxiety, tachycardia and sudden tremors. In this case, it is possible that the subject is suffering from a depressive problem.
Swollen lymph nodes: if the subfebrile temperature is accompanied by an increase in lymph nodes and profuse sweating, especially at night, then it may be associated with a tumor or infection, for example, mononucleosis.

Causes of low-grade fever

When subfebrile temperature is sporadic or intermittent, has a correlation with certain periods of the year, month or day, then it is almost certainly associated with a non-pathological cause.

Temperature reasons ...

Prolonged and persistent low-grade fever, which persists for many days and appears mainly in the evening or during the day, is often associated with a specific disease.

Causes of low-grade fever, without pathology:

Digestion: after eating, the digestive processes cause a physiological increase in body temperature. This can cause a mild low-grade fever, especially if you have hot food or drinks in your body.
Heat: In summer, when the air reaches high temperatures, being in an extremely hot room may cause increased body temperature... This happens especially often in children and newborns, whose body thermoregulation system is not yet fully developed.
Stress: in some people, especially sensitive to stressful events, subfebrile temperature can be interpreted as a reaction to stress. Typically, a rise in temperature occurs in anticipation of a stressful event or immediately after it has happened. This type of low-grade fever can even appear in babies, for example, when he cries very intensely for a long time.
Hormonal changes: In women, low-grade fever can be closely related to hormonal changes. So in the premenstrual stage, the body temperature rises by 0.5-0.6 ° C, and this can determine a slight increase in temperature in the range from 37 to 37.4 ° C. Also, in the early stages of pregnancy, hormonal changes lead to a similar increase in body temperature.
Season change: within the framework of the change of season and a sharp transition from high temperatures to cold, and vice versa, a change in body temperature may occur (without a pathological cause).
Medications: some medications have low-grade fever as a side effect. Among them, antibacterial drugs of the class of beta-lactam antibiotics, most anticancer drugs and other drugs such as quinidine, phenytoin and some components of vaccines should be distinguished.

Pathological causes of low-grade fever

The most common pathological causes of low-grade fever are:

Neoplasms: Tumors are the main cause of persistent low-grade fever, especially in the elderly. Among the tumors that most often lead to an increase in body temperature are leukemia, Hodgkin's lymphoma, and several other types of cancer. Usually, low-grade fever in the case of a tumor is accompanied by rapid weight loss, a strong feeling of fatigue, and in the case of tumors involving blood cells, anemia.
Viral infections: one of the viral infections that causes low-grade fever is HIV, which leads to the development of acquired immunodeficiency syndrome. This virus typically destroys the subject's immune system, thus causing wasting, resulting in a variety of symptoms, one of which is low-grade fever, opportunistic infections, asthenia, and weight loss. Another viral infection in which persistent low-grade fever appears is infectious mononucleosis, known as kissing disease, due to its transmission of salivary secretions.
Respiratory tract infections: Low-grade fever is often present in the case of an infection involving the respiratory tract (such as pharyngitis, sinusitis, pneumonia, bronchitis, or the common cold). One of the most dangerous respiratory tract infections that causes low-grade fever is tuberculosis, which is accompanied by profuse sweating, asthenia, weakness, and weight loss.
Thyroid problems: low-grade fever is one of the symptoms of hyperthyroidism, caused by thyrotoxic destruction of the thyroid gland. This destruction of the thyroid gland is called thyroiditis and is often caused by a viral infection.
Other pathologies: there are other diseases such as celiac disease or rheumatic fever caused by streptococcal infection, beta-hemolytic type, which include the appearance of low-grade fever. However, in these cases, low-grade fever is not the main symptom.

How is low-grade fever treated?

Low-grade fever is not a pathology, but a symptom by which the body can indicate that something is wrong. In fact, there are many diseases that can lead to persistent low-grade fever.

However, often slight increase in body temperature has no pathological causes and can be compensated for using simple natural remedies.

It is difficult to find the cause of low-grade fever, but, in any case, you should consult a doctor.

Natural remedies for non-pathological low-grade fever

Natural remedies such as herbal medicine can be used to combat symptoms caused by low-grade fever. Of course, you should consult your doctor before resorting to any of these remedies.

Among medicinal plants used in the case of low-grade fever, the most important are:

Gentian: Used for intermittent low-grade fever, this herb contains bitter glycosides and alkaloids, which gives it antipyretic properties.

Used as a decoction: 2 g of gentian roots are boiled in 100 ml of boiling water, left to infuse for about a quarter of an hour, and then filtered. It is recommended to drink two cups a day.

White willow: contains, among other active substances, derivatives of salicylic acid, which have the same antipyretic effect as aspirin.

The broth can be prepared by bringing to a boil a liter of water containing about 25 grams of white willow root. Boil for about 10-15 minutes, then filter and drink two to three times a day.

Linden: useful as an associated antipyretic, linden contains tannins and mucus.

It is used in the form of infusions, which are prepared by adding a tablespoon of linden flowers to 250 ml of boiling water, followed by infusion for ten minutes and filtration, you can drink it several times a day.

Body temperature is an important indicator of the functioning of the body. If its meaning changes, it can be a consequence of either natural or pathological processes occurring in the body.

Moreover, its minimum value falls on the morning period (4-5 hours), and the maximum indicator is reached at about 17 hours.

If the temperature jumps during the day (36 - 37 degrees), it is explained by the physiological state of systems and organs, when an increase in temperature values is necessary to activate their work.

When the body is at rest, a decrease in body temperature occurs, therefore, jumps from 36 to 37 degrees during the day are regarded as a variant of the norm.

The human body is a heterogeneous physical environment where areas are heated and cooled in different ways.

Contrary to popular belief, the measurement of temperature indicators in the armpit may be the least informative, this often becomes the reason for obtaining unreliable results.

In addition to the armpit, body temperature can be measured:

in the ear canal,
in the oral cavity,
rectum.

Medicine distinguishes between several types of temperature. An increased temperature is considered to be an indicator of 37.5 degrees, at which there are other uncomfortable manifestations.

Fever is called a temperature of unknown origin, at which the only symptom is a prolonged rise in temperature from 38 degrees. The condition lasts from 14 days or more.

Subfebrile temperature is considered to be up to 38.3 degrees. This is a condition of unknown origin, in which a person periodically has a fever without additional symptoms.

Specificity of physiological conditions

In addition to wakefulness and sleep, jumps in temperature indicators during the day are caused by the following processes:

overheating,
active physical activity,
digestion processes,
psycho-emotional excitement.

In all these cases, temperature jumps from 36 to 37.38 degrees can be observed. The condition does not require correction, since the temperature rise occurs against the background of the natural physiological states of the body.

The exceptions are cases when temperature jumps from 36 to 37 degrees are accompanied by additional symptoms, namely:

headache
discomfort in the area of the heart,
the appearance of a rash
shortness of breath
dyspeptic complaints.

If these symptoms are present, it is necessary to consult a doctor in order to exclude the development of allergic reactions, vegetative vascular dystonia and endocrine disorders.

Among other things, the jumps in the general body temperature during pregnancy are also due to the physiological specifics. At this time, significant changes in hormonal levels occur, since progesterone is produced in large quantities, which leads to jumps in body temperature from 36 to 37 degrees.

As a rule, changes in temperature indicators are observed in the first trimester, but there are cases when the condition continues throughout the pregnancy, and the reasons should be found out.

Changes in body temperature pose an additional danger in the presence of:

catarrhal phenomena
dysuric signs,
stomach ache,
rashes on the body.

A consultation of doctors is shown to exclude diseases caused by pathogenic pathogens.

Ovulation can also change a woman's body temperature from 36 to 37 degrees. Typically, the following symptoms are present:

irritability,
weakness,
headache,
increased appetite,
swelling.

If in the first days of menstruation, this unpleasant symptomatology passes, and the temperature drops to 36 degrees, then there is no need for medical examinations.

Also, the indicator can change with climacteric syndrome, which is also due to a change in the amount of hormones. The woman does not understand why the state has changed. There are additional complaints:

hot flashes
increased sweating,
increased blood pressure,
failures in the work of the heart.

Such temperature drops are not dangerous, but in the presence of other complaints and finding out the reason, in some cases hormone replacement therapy is indicated.

Temperature jumps can be with thermoneurosis, that is, the temperature rises to 38 degrees after stress. It is possible to draw a conclusion about the presence of this pathology by excluding more significant reasons for the appearance of hyperthermia.

Sometimes an aspirin test may be shown, which involves the use of an antipyretic drug at an altitude of temperature, and subsequent monitoring of the dynamics.

If the indicators are stable, then 40 minutes after taking the drug, he can more confidently assert the presence of thermoneurosis. In this case, the treatment will consist in the appointment of restorative procedures and sedatives.

The most common causes of temperature jumps from 36 to 37 degrees in adults are:

heart attacks,
purulent and infectious processes,
tumors,
inflammatory diseases,
autoimmune conditions,
trauma,
allergies,
endocrine pathologies,
hypothalamic syndrome.

Abscess, tuberculosis and other infectious processes, most often, the reasons why there is a change in temperature from 36 to 38 degrees. This is due to the pathogenesis of the disease.

When tuberculosis develops, the fluctuations between evening and morning temperatures often reach several degrees. If we are talking about severe cases, then the temperature curve has a hectic form.

This picture is also typical for purulent processes. In such a situation, the temperature rises to 38 degrees and above. When the infiltrate is opened, the indicator returns to normal in a short time.

Also, most other inflammatory and infectious diseases have such a symptom as sudden changes in temperature during the day. In the morning it is lower, in the evening it is higher.

The temperature can rise in the evening if such chronic processes as:

adnexitis,
sinusitis,
pharyngitis,
pyelonephritis.

Hyperthermia in these cases passes with additional unpleasant symptoms, so you should consult a doctor for examination and prescription of therapy for a specific disease. Antibiotic treatment, which is often prescribed for inflammatory diseases, will help normalize temperature readings.

If hyperthermia is caused by a tumor process, then depending on its location, it proceeds in different ways. So, there may be sharp jumps in temperature, or it will remain at a constant level for a long time.

To clarify the diagnosis, a comprehensive examination should be carried out, which includes:

hardware methods,
instrumental analysis,
laboratory diagnostics.

A timely diagnosis will lead to effective treatment of the disease. This approach is also used in hematology, where temperature jumps from 37 to 38 degrees can occur due to various forms of anemia or leukemia.

Temperature jumps can be observed due to the pathology of the endocrine system. If there is thyrotoxicosis, which proceeds with hyperfunction of the thyroid gland, then the following additional symptoms should serve for consultation with an endocrinologist:

weight loss,
irritability,
sudden changes in mood
tachycardia,
interruptions in the work of the heart.

In addition to general clinical analyzes, ultrasound and ECG, a study of thyroid hormones is prescribed, then a treatment regimen is created.

Principles of therapy

As you know, in order to prescribe the optimal treatment, you should identify the cause of the onset of symptoms. At elevated temperatures, the patient is examined.

When the diagnosis is confirmed, treatment should be prescribed directly based on the characteristics of the pathology. It can be:

antibiotic therapy,
antiviral agents,
anti-inflammatory drugs,
antihistamines,
hormone therapy,
general strengthening measures,

An increase in temperature is a defensive reaction that enables the body to effectively and quickly fight disease-causing elements.

The appointment of antipyretic drugs is not justified if the temperature is up to 37 degrees. In most cases, the appointment of antipyretic medications occurs at a temperature of more than 38 degrees.

Drinking plenty of warm drinks is also indicated, which increases sweating and promotes heat transfer. It is necessary to provide cool air in the room where the patient is. Thus, the patient's body will have to warm the inhaled air, while giving off heat.

As a rule, due to the actions taken, the temperature drops by a degree, which means that the patient's well-being improves, especially with colds.

Conclusion

Based on the foregoing, it is worth emphasizing that temperature jumps can be seen in both physiological and pathological conditions. To confirm the safety of hyperthermia, many diseases must be ruled out.

If a person has a body temperature of 37 to 38 degrees, within a few days you need to seek medical advice and undergo a medical examination. If a pathogenic agent is identified, it is necessary to urgently begin therapeutic procedures. An interesting video in this article logically completes the topic of temperature.

Moreover, its minimum value falls on the morning period (4-5 hours), and the maximum indicator is reached at about 17 hours.

When the body is at rest, a decrease in body temperature occurs, therefore, jumps from 36 to 37 degrees during the day are regarded as a variant of the norm.

Conclusion

It's okay, my fluctuations are much wider.

in the morning the pace is 36.4 and in the evening 37.0 Who was this? who knows - why this happens and is it normal?

hi i have it so in the morning 36.5 in the evening 37.2 this is normal because the evening pace does not need to be taken into account.

Hi Elena glider, thanks for the answer. and you do not know why it rises so much? Just wondering. And the glider in the name of Cho means? don't you do gliding? I have mates in this sport

Hello. This is normal BT, and TT always rises in the evening. Therefore, BT should be measured without getting out of bed after sleep.

And for the future, in the second phase BT and TT will also be higher than in the first, this is also normal.

Fever can rise due to nerves, fatigue and many other factors.

Any healthy person has an evening temperature slightly higher than morning.

And in my morning, when measuring BT - 36.6, I slept for three hours without getting up became 37.0 and then went to the toilet in the kitchen measuring 37.6 and what is it ??

Sorry what's not on your blog, it's just the same topic

kapitosha I have a similar problem, too, bt jumps and do not know which one to put.

In the morning, the body temperature is measured AT REST, i.e. when a person sleeps, all processes slow down, the body does not expend energy, there is no stress, therefore, the pace is lower, and during the day you run up, nerves, movement, pulse quickens, blood flow increases - this leads to an increase in the pace. you can even find a pattern if in the evening, for example, 37.7, then in the morning it will be 37.2. It is the same for me.

I completely agree with Mamka L. I have exactly the same.

And I show me the evening pace of what will happen in the morning, if it dropped to 36.6, then in the morning wait for 36.2, and if 36.8, then it will rise. Usually in the second phase I measure the evening.

Tell.

Body temperature

For the third week now, my body temperature is exactly 36 degrees Celsius. I feel great, nothing hurts, etc. What does this mean?

For a person, a temperature in the range of 35.7 - 37.2 is considered normal.

I am 32 years old, for several years now I have constantly had a subfebrile temperature of 37.1-37.3. Chronic tonsillitis is also available. From time to time, there are plugs in the tonsils, sometimes with a headache and weakness. If I take a course on a digital basis, then my temperature does not drop. Antibodies to HSV-1 are found in the blood; sometimes it manifests itself as a herpetic rash on the lip, 2 times a year. I am very tired of such constant temperature. What should I do?

Regarding chronic tonsillitis, I can recommend a new drug, tonsillotren, or taking septephril, irrigation of the tonsils with Jox. The IRS-19 has proven itself quite well.

As for herpes, it is better to use acyclovir tablets, or to pierce acyclovir (or drugs based on it). For external treatment, use acyclovir-based ointments - herpevir. virolex, zovirax, etc.

Possible nonspecific stimulation of the body - taking adaptogens - ginseng, eleutherococcus.

After immunological examination, immunomodulators can be used to correct the cellular link of immunity. But this should be done only after consulting an immunologist.

I was ill for two and a half months. The first diagnosis was ARI, then ARVI, then bronchitis. And during the whole time there was a subfebrile temperature. Moreover, the temperature rises within an hour after I wake up in the morning. And it doesn't matter what time I wake up: at 8.00, at 9.00 or 11.00. After examination by the ENT, the diagnosis was made of chronic tonsillitis toxicoallergic form (TAF1). Did an ultrasound of the abdominal cavity - the liver was slightly enlarged. Bilateral tonsillectomy was performed (tonsils were removed). The tonsils were really bad, loose, there were plugs and pus). Rinsing did not help. 2 weeks have passed since the operation. The temperature after the operation dropped to 36.9, but then for some reason it became again. 2 and the temperature behaves very strangely, for example, it has risen to 37.2 and by the evening it can drop to 36.9 (although it should be the other way around), but not lower - 36.9. But today it does not go down, but it remains 37.1, by the way, over these 2.5 months my weight has dropped by 11 kilograms. What could it possibly be? Can the temperature persist for so long? Blood tests show neither AIDS, nor hepatitis B or C, nor tuberculosis (he did a fluorography at a phthisiatrician) and, in general, the blood is normal ESR, leukocytes, etc. What could it be? In principle, I had an ulcer of 12 rings. intestines, gastroduodenitis, but as far as I know, an ulcer does not give a temperature. Maybe it is some kind of tumor (God forbid).

Unfortunately, you have not indicated your age. In addition, the situation is not simple and a fairly large number of diseases can be the cause of a low-grade fever. These are systemic diseases of the connective tissue (systemic lupus erythematosus, rheumatoid arthritis) and tumors and tuberculosis (a single fluorography does not exclude this disease). In your case, a thorough examination in a therapeutic hospital is necessary.

Tell me what a low temperature 34.8, 35.2 can mean with a general bad condition: fever, the whole body aches and hurts like with the flu, it also resembles a cold.

This condition can be in weakened people, with reduced immunity, after suffering long-term illnesses. Just in case, change the thermometer, measure the temperature in your mouth. If it is really low - donate blood - a general analysis, and after recovery - blood for the immune status.

For one and a half months I have had a high temperature (37-37.7). Has gone through a lot of all kinds of tests, including for AIDS - the results are negative or everything is normal. Not any discomfort, except for fatigue and weakness in the evening due to temperature - no. Maybe you know something about this?

Within three months, I have seen an increase in body temperature to 37.4. Moreover, in the morning 35.36.6 by lunchtime 37.0 by the evening 37.4. Therapist's diagnosis: subfebrile condition of unclear etiology. Analyzes. Tuberculosis (serology) - all negative. The Mantoux reaction is normal. HIV-1 and HIV-2 tests are negative. Latent infection (ureaplasma, mycoplasma, chlamydia) - negative. The general clinical analysis of blood is normal. A biochemical blood test is normal. the functions of the tonsils (in ENT) are normal. (sowing gave a normal autoflora, the immune function of the tonsils is normal). Ultrasound of the thyroid gland, pelvic organs (liver, kidneys, spleen, etc., with the exception of the intestines) - the state is normal. In addition to temperature, I do not observe any other symptoms. Please advise what tests to pass in order to somehow clarify the situation.

At a young age, the so-called "thermoneurosis" (a special type of vegetative-vascular dystonia with impaired thermoregulation) is often encountered. However, it can be diagnosed only by excluding all other diseases occurring with a slight increase in body temperature, which was done in your case. Additionally, you can take a urine test according to Nechiporenko. We also draw your attention to the possibility of perverted temperature readings when measured in the armpit. The fact is that the temperature measured under the tongue or in the rectum (which is accepted abroad) is considered to be true, and not on the surface of the skin. In this case, the normal temperature is up to 37.5C. Normally, the difference between the temperature in the oral cavity and in the armpit is about 1 degree, but not less than 0.5C. With thermoneurosis, the difference is less than 0.5C, and it is also possible that the temperature in the armpit will be higher than in the oral cavity.

I'm 28 years old. I have t 37.2-37.4 for two months now. They were on sick leave for a month. All kinds of doctors checked for all kinds of tests. And she was discharged with a diagnosis of vegetative-vascular dystonia, thermoneurosis. Since then, the temperature has remained at the same level, although I drink all sorts of ginsengs, lemongrass in the morning, and motherwort and peonies in the evenings. I drink immunal, echinacea, eleutherococcus. And I do not understand at all what the temperature has to do with it? After all, the temperature is an indicator of the inflammatory process in the body, but my leukocytes are normal (they always were, I donated blood many times), my lungs are also in order, and other organs are healthy too (all sorts of ultrasound, smears). Nothing hurts, and there seems to be no inflammatory process anywhere. But why then does the temperature not go down? She has already worn me out. I have never been ill with anything before, and now I feel weak and powerless all the time. Tell me, can there be such a diagnosis - thermoneurosis, I have not found in any reference book. And not a single description of vegetative-vascular dystonia says anything about temperature. And if so, how to treat it? Why doesn't it pass in any way?

An elevated temperature may indicate not only an inflammatory process, but also a violation of thermoregulation. Vegetovascular (or neurocirculatory) dystonia with impaired thermoregulation does exist. A characteristic prolonged (for months) low temperature (up to 37.8 C) without chills and fever, while after sleep the temperature can return to normal; the temperature does not decrease under the influence of antipyretic drugs; possible spontaneous normalization of temperature and resumption of subfebrile temperature (for example, after acute respiratory viral infections). Normally, the body temperature in the armpit is 0.2-0.5 C lower than under the tongue. With NCD, the temperature under the tongue can be equal to or lower than the temperature in the armpit. Treatment is carried out by vegetologists. In Moscow, you can contact the All-Russian Scientific Center for Autonomic Pathology (Rossolimo St., 11. tel.).

I am 39 years old, for two months in the afternoon the temperature rises 37.1,37.5. There is an abrupt increase in pressure up to 170/110, lethargy, weakness, there are no more symptoms. Ultrasound, radioisotope rheography of the kidneys, bladder, general analysis of urine, blood - normal, culture of urine for flora - normal. Ultrasound of the prostate gland revealed calcified areas, analysis of the juice of the prostate gland is normal. He underwent a course of treatment for chronic prostatitis. Ultrasound of the heart showed moderate aortic valve insufficiency and mitral regurgitation of 1 tbsp. At a rheumatologist, a blood test for rheumatic tests and sterility is normal. I have been drinking alcohol for a long time, and have stopped drinking alcohol completely for the last four months. Please advise in which direction should I undergo further examination? The rheumatologist offers to go to the cardiac dispensary for examination, the therapist advises to find a "good" urologist.

An increase in temperature in the afternoon may indicate the presence of a focus of chronic infection, the search for which is necessary and best done in a hospital (typing a number of flaccid infections such as legionellosis, toxoplasmosis, mycoplasmosis, yersiniosis, cytomegalovirus, influenza viruses and many others). Culture of blood for sterility will determine the presence of a microbe in the blood. All this will help determine the correct treatment tactics. In addition, an episodic spasmodic increase in blood pressure obliges to conduct an examination in terms of searching for adrenal gland diseases (adrenal hormones before and after a crisis, a computer study of the adrenal glands, etc.). The list of diagnostic tests is beyond the competence of the outpatient clinic. Thus, it is necessary to follow the advice of a rheumatologist and undergo a detailed examination in a hospital. In your situation (critical age, chronic calculous (?!) Prostatitis), you should not neglect the therapist's advice about the urologist: you should be monitored by him (as well as by the therapist) for the rest of your life.

He was treated for chlamydia and trichomoniasis. At the end of the course of treatment, the symptoms of the disease disappeared. Except that for about 3-4 months there were unpleasant sensations from the yeast. Immediately after the end of the treatment, I did control tests (smears), the result was negative, then after 3 months I donated blood for chlamydia, the answer was negative, the same control test was done half a year after the end of treatment, the answer was negative. After a couple of months, my temperature rose. I passed various blood tests for sterility, for lamblia, for hepatitis, did an ultrasound scan, X-rays and so on, but the temperature and lethargy last for about a year, the doctors shrug their shoulders, I decided to go for computer diagnostics (although I don't really trust her) according to the Fohl method. And there they gave me the result that I had chlamydia.

1) Can I have chlamydia if laboratory tests do not find them (say, in the prostate gland)?

3) How can I find the cause of my illness if I have no other symptoms besides temperature (36.9-37.2) and feeling unwell?

Answer: Fohl's method is based on the determination of "electromagnetic waves" emitted by the cells of organs. So chlamydia itself cannot be determined by this method. But it is quite possible to determine in which organ there is a pathology. You can even determine approximately what kind of process it is (in your case, it seems to be an inflammation in the genitourinary organs). Perhaps it is prostatitis or cystitis, which can be caused not only by chlamydia, but also by common flora (E. coli, streptococcus, staphylococcus aureus). Get tested for tuberculosis, which can also cause fever. The reason for the high temperature may be a thermoneurosis, this is in the competence of a neuropathologist.

The son is 21 years old. In the last two years, he has often suffered from colds. I took antibiotics a lot. Constantly holds t 37.1-37.4. Pressure 150 to 100. Donated blood for sterility. The microbe corynebacteiin was released. The body does not respond to antibiotics such as penicillin, tetracycline, levomecitin, cephalosparins. I ask you to answer how to cure this disease, what is it called, what complications can there be in the future, can this microbe give a temperature of 37.1 - 37.4? Doctors don't give a definite answer

Your son may have a non-toxigenic diphtheria strain. Your doctor may consider it possible to prescribe septephril or decamethoxin, erythromycin, rinse with an alcoholic solution of chlorophyllipt. Observation by an infectious disease specialist is necessary

I am 24 years old. She was not sick with anything except measles. I had a temperature of 37-37.5 for 3 months (since mid-December 2000). I got sick 2 weeks after being vaccinated against influenza (Russian). It all started with a bad cough and a cold. I have never had an allergy, but after vaccination I noticed a strange reaction to drops from a cold (except for naphthyzine). It manifests itself in the fact that I cannot look (especially at the light), since the vessels of the eyeball become very inflamed, tears constantly flow from the eyes for several hours. Without taking drops, this is not, but the vessels are still somewhat inflamed and sometimes (especially during the runny nose) the eyes water. This was not the case before. Examined by specialists: ENT, endocrinologist, gynecologist, neuropathologist, phthisiatrician, ultrasound of the abdominal cavity and kidneys, cardiogram was done. All experts said that the temperature was not their part. The head of the therapeutic department made the assumption that I had a "normal" temperature, but the norm for me was always exactly 36.6. I always feel an increase to 37, because I usually get sick without a fever (more than 37.5 was 3 times in my life). The last month I did not notice the temperature up to 37.5, because I got used to it (except for the case when I had a cold). Nothing but a non-hormonal enlargement of the thyroid gland was found (hormones at the limit = 2, antibodies to TG = 7). I take pycnogenol for a week (an antioxidant that increases the protective functions of the body). All the time of illness (and still) I have enlarged lymph nodes under the chin. In general, I have a weak lymph system and it is these nodes that almost always increase during the period of illness. The third day (after catching a cold and for treatment purposes - a sauna), the temperature dropped to 36.7-36.8 within 3 hours after the sauna. What was the temperature associated with and is it possible to increase it again?

You are asking a very difficult question. It is difficult to say in absentia about the reasons for the rise in temperature, because there may be several reasons. A thorough examination is necessary, possibly in a hospital setting. As for the reaction to nasal drops, its most likely cause is allergy (by the way, it can also be the reason for the increase in temperature). As for my point of view, I would first of all rule out tuberculosis (chest x-ray), lymphogranulomatosis, hyperthyroidism (increased thyroid function) and systemic connective tissue diseases (systemic lupus erythematosus, scleroderma, etc.). In addition, chronic infection, such as chlamydia, is also possible. In general, I repeat, there can be a lot of reasons.

The fact is that I already wrote to you that I have a high temperature for a long time (already 4 months 37-37.5). The temperature dropped for about a week. Then it resumed. Moreover, all 4 months I have enlarged lymph nodes under the chin (this is always with me when I am sick). Now some new symptoms have appeared: in 3 days the nodes under the knees have greatly increased (it even hurts to walk), which has never happened before. Plus, there is an itching in the perineum for a week (although it began immediately after taking hormonal pills using the method of postcoital contraception). Itching, however, has somewhat diminished. It began, as I already wrote, with a flu shot (Russian): something like a cold with a severe cough. Now the cough appears from time to time, and from time to time redness and inflammation in the throat. Doctors did not find anything (gynecologist - routine examination, therapist, ENT, endocrinologist, phthisiatrician, neuropathologist). This disease worries me very much. 2 months ago I was even tested for AIDS (because 1 year ago I was slightly cut at my own house by a girl, apparently a drug addict). And at the beginning of December last year, I noticed that I had a dot on my arm, like from an injection. And since mid-December, my temperature has increased. I heard that there are people suffering from speed phobia. I hope that I am among them, and not among the infected. Although I did not suffer from suspiciousness before (before the attack of the aforementioned drug addict). There is one more thing that may matter: in October 2000 my dad died (I'm 24 years old). I somehow unexpectedly went through it calmly, forced myself not to think, but it is possible that internal tension was growing (especially since now I have to provide and take care not only of myself, but also of my mother), although I have had my life since December the most interesting and intense began. In addition, a doctor friend said that perhaps I was allergic to adrenaline, because after taking drops from a cold containing it (or causing it to increase in the blood, I do not really understand this), my eyes become very inflamed and watery. Which specialists do I need to check and which tests to pass.

Because you are worried about whether it is AIDS or something similar. you need to start with the tests of RW, HIV, hepatitis B and C. It is necessary to be examined by a dermatovenerologist, and then by a rheumatologist and, if possible, by an immunologist.

I am 21 years old, there was no sexual intercourse at all. A year ago, a constant temperature began from 37.0 to 37.5. At first I did not attach any importance to this, but after about 3-4 months dizziness began, my appetite disappeared, and sometimes there was vomiting. Menstruation was violated - at first there was very little discharge, instead of 4 days - only a day, and then the regularity was violated. The gynecologist thought at first that I was pregnant. Prescribed injections (hormones), drank medications. They also treated the throat with laser therapy. The gynecologist diagnosed a hormonal disorder due to nervous stress (it seems so). There was stress - a friend was taken to the Army. In general, after the cycles of injection and medication, nausea and dizziness disappeared, and menstruation returned to normal (more abundant and regular). But the temperature did not pass. They reassure me so - if you marry your husband, it will pass. Please, give advice, tell me what else can be done, I am very afraid that this will somehow be addressed to future children.

You need to see a general endocrinologist (not a gynecologist). The symptoms that you describe are suspicious of the pathology of the hypothalamus and pituitary gland (parts of the brain). In addition to their other functions, these departments control the work of the reproductive system, therefore their pathology affects its work.

A young woman (27 years old), already the 3rd year, the increased body temperature: 37-37.3 degrees. She underwent a full examination - all indicators are normal, there is no inflammation. Now I'm used to it and don't notice. At the same time, for the third year, with interruptions of three months, I have been taking the drug "Triregol". Can this drug cause a fever, and what side effect (effect) on the body can this have in the future?

The center of thermoregulation is located in the brain - in close proximity to the department that is affected by the intake of hormonal contraceptives. Therefore, if there is such a time dependence between the intake of COCs and the change in temperature, and a complete examination was carried out and no other reasons were identified, it can be assumed that the change in temperature is associated precisely with the intake of Tri-Regol. You should cancel the drug for more than 3 months, and monitor the temperature (while protecting yourself with other methods). This is not a normal or harmless body reaction. If it is proved that it is Tri-Regol that is the cause of this condition, then, apparently, hormonal contraception will need to be replaced by other methods (barrier, chemical, IUD). Such an elevated temperature creates unfavorable conditions for the work of other organs and systems, leading to their faster "wear".

Could someone explain why the temperature appears.

those. what happens in the body such that a temperature appears.

Man belongs to warm-blooded creatures. This means that his body temperature does not depend (relatively) on the ambient temperature. Therefore, fluctuations in temperature outside do not normally affect our condition. The temperature itself, other than absolute zero, is needed so that chemical reactions of the formation of substances to build an organism, the decay of substances to obtain energy, etc. can occur. Nature has found the optimum temperature at which these life processes occur with the necessary speed - 37 degrees Celsius in the blood. And there is a special thermoregulation system, the task of which is to maintain the temperature at this constant level, regardless of the air temperature. For example, with the threat of overheating, the activity of the sweat glands increases, water evaporates, taking energy for this process, and the body cools down, or rather does not overheat. With the threat of hypothermia, muscle tremors begin - the muscles contract, releasing energy, and no movements are performed, thus. energy is spent not on work, but in heat - the body warms up.

Microbes that enter the body release all sorts of substances into the blood, including those that disrupt the work of the thermoregulation system - the body begins to consider it normal and maintain a higher temperature (temporarily). Up to a certain point, this slight increase in temperature is useful: it activates the immune system faster, destroys microbial cells, and produces more energy for recovery. Therefore, a slightly elevated temperature (up to 38 degrees) is advisable not to knock down with aspirin and similar drugs.

However, when microbes multiply and begin to dominate the immune system, the damage to the thermoregulatory system can become too severe, and such an increase in temperature can lead to the destruction of its own proteins. Such a fever is harmful and must be treated.

Temperature is an indicator of a certain level of equilibrium of physical and chemical processes in the body (and they occur with the formation of heat). The temperature reaction is regulated by special nerve cells (nuclei) located in the hypothalamus (formation in the brain).

Temperature rise is caused by two main reasons: physical and chemical. With an increase in temperature for physical reasons, we are talking about a violation of heat transfer (most often it is heatstroke, when as a result of muscle activity, heat production increases, but there is no sufficient return of this heat in a suffocating, moisture-saturated atmosphere).

Chemical causes The temperature rises due to the increased generation of heat on the basis of a violation of the chemical regulation of heat generation in a special center of the hypothalamus (irritation of this center by toxins circulating in the blood or proteins foreign to the body). Causes of a tumor, cerebral disorders (hemorrhages in the brain and meninges), blood diseases (leukemia), a decrease in the number of platelets, etc., inflammatory diseases (infections, thrombophlebitis, inflammation of a vein, with a thrombus inside), myocardial infarction, drug fever, autonomic fever (in persons with increased excitability of the autonomic nervous system, intestinal bleeding, dysfunction of the endocrine glands (thyrotoxicosis, crises with adrenal gland diseases), gout and many other diseases.

If you do not find out the reason for the increase in temperature (for this, as can be seen from the above, a thorough examination is necessary), then the disease from the initial period passes into a far-reaching period and is difficult to treat. For example, a banal inflammation (furuncle, an abscess of the skin) can result in sepsis and even lethal (fatal) outcome.

At the same time, the temperature reaction also plays a protective role. First, the body with a high temperature signals that there is disorder in it. And secondly, for example, many viruses die at elevated temperatures, the protective function of increasing temperature (hyperthermia).

For three years now I have had a constant high body temperature - from 37 to 37, 5. The treatment took place at the gynecologist, as the left appendage hurts. According to the doctor, he is constantly softened. Once the appendage was greatly enlarged. I was told that the inflammation caused a cyst, which will soon dissolve. And so it happened. In 1998, I was injected with antibiotics for 8 months. But the temperature has not subsided until now. The doctor said that she did not know what was the matter. Antibiotics triggered my asthma. For more than a year I have been suffering from vaginal candidiasis. I tried everything, it doesn't help. there was no remission for a single day. I have been drinking fucanazole for the second month. There is practically no discharge, but the temperature is kept. All three years I feel very bad. Constantly strong weakness, cystitis tortured. Personally, I suspect I have candidiasis or other mycosis. What do I need to do (what tests to take, etc.) in order to achieve the correct diagnosis. Our doctors do not bother themselves to put it on me. In general, what does my painting look like?

You need to do the following tests:

1.X-ray of the chest organs

2. Examination at the tuberculosis dispensary (tuberculin tests)

6. Examination by a rheumatologist and determination of lupus anticoagulant, LE-cells, rheumatoid factor, etc. dr (according to the recommendations of a rheumatologist)

7. immune status and interferon status with determination of sensitivity to immune drugs, consultation with an immunologist.

8. General urine analysis, urine analysis according to Nechiporenko

Further actions - depending on the results obtained.

And sometimes the body temperature remains normal throughout the day, but in the late afternoon it invariably rises.

Such a phenomenon does not always indicate the development of the disease, but it nevertheless speaks of certain changes in the human body.

In some people, such changes generally become a common condition, because this is how their thermoregulatory system functions. And yet you should very closely consider the reasons for the appearance of such numbers on the thermometer.

Every evening, the temperature rises to 37 degrees in adults and children for a variety of reasons. The indicators will be influenced by various factors: physiological and pathological.

Of course, if you complain about your own health, you should consult a doctor. But sometimes a temperature of 37.1 (in the evening) does not mean something terrible, but is a variant of the norm.

But if these symptoms continue for a long time, you need to see a doctor. Most likely, this condition indicates an immune response to a certain threat or trouble.

A person rarely resorts to using a thermometer if there are no additional health complaints and signs of illness. But, having carried out periodic measurements, you may be surprised that there is a temperature of 37 in the evening, but not in the morning.

Thermometer readings are influenced by many factors:

time of day (it is known that the thermometer readings are lower in the morning than in the evening, and during deep sleep the lowest values are noted);
the rhythm of life (for people with an active lifestyle, the thermometer readings are always higher);
type of measuring device (it is generally accepted that electronic thermometers have an error, in contrast to mercury devices);
season and weather conditions (in winter, the temperature naturally rises, and in summer it becomes lower);
physiological and pathological conditions.

Physiological conditions that increase temperature

Hyperthermia does not always arise due to a certain threat. Very often it is a consequence of overload or hormonal changes in the body.

This can happen due to the ingestion of hot or spicy food, nervous tension, and the prescription of certain medications.

Sometimes such figures are not considered a pathology at all, but only a borderline state of the norm. Only in the case of a strong increase or an unacceptably long period of hyperthermia is a comprehensive examination of the patient's body prescribed.

Among women

Many women have a periodically high body temperature. This is why this is happening. During the menstrual cycle, hormones are constantly produced.

On certain days, the release of some substances becomes more, while others - less. Immediately after ovulation (the release of the egg from the ovary), progesterone comes into play.

This hormone is very important for maintaining the second phase of the cycle and the development of pregnancy. Thanks to him, relaxation of smooth muscles occurs. Also, progesterone affects thermoregulation, reduces the rate of heat transfer.

Before menstruation, a woman may notice that her body temperature has increased by fractions of a degree.

As soon as the bleeding begins, the progesterone level will decrease and the thermometer readings will return to normal.

If pregnancy has occurred, then increased values may persist for several months until the placenta is formed. For expectant mothers, it is considered the norm if the thermometer shows 37-37.2 degrees.

The rise in temperature in the evenings is usually explained by a sharp hormonal change in the body, toxicosis during pregnancy, increased metabolic rate, reflex influences when drinking alcohol or the usual processes of thermoregulation.

The reasons why the temperature rises in the evening 37:

during premenstrual syndrome
while carrying a child
when feeding a baby
at ovulation
shortly after the birth of children
with menopause
after eating too much and too much
with excessive consumption of strong alcoholic beverages
with significant overheating in the sun, etc.

For some women, this temperature is generally normal, accompanying them all their lives.

For other ladies, in the evening, the numbers often change due to increased fatigue or severe nervous tension.

In men

Representatives of the stronger sex also often complain that the temperature rises to 37 in the evening without symptoms.

This may be due to hypothermia or overheating, injury, nervous strain.

Hyperthermia can occur due to excessive consumption of spicy food or hobby for alcoholic beverages.

The temperature can jump in the evening due to significant muscle strain after hard physical work or increased sports training.

The most commonplace reason can be a long reception of a too hot bath or shower, a long sleep in an armchair by the battery itself, a very warm dressing gown or suit.

In old people, temperature fluctuations can have their own characteristics. During the day, for example, there will be some hypothermia, and by the evening the numbers will creep to around 37 degrees.

In addition, in men, as in women, such indicators can be quite normal and correspond to their physiological norm.

In children

The child often causes severe anxiety to his parents because of the temperature that has jumped in the evening.

However, it is worth noting that in children under five years old, due to their imperfect thermoregulation, 37.2 - 37.3 degrees can be considered a normal temperature.

Most often, a rise in temperature at night occurs soon after an infection or other childhood illness.

The baby's immunity has not yet fully strengthened, so his circulatory system reacts with an increased release of lymphocytes, accompanied by hyperthermia.

This is a normal reaction, indicating that the defenses of the child's body are on guard for his health.

A rise in temperature in the evening to 37 in a child can also be explained by the most common reasons:

Overly active games
too warm clothes
vaccine reaction
teething
hot drink at night
a blanket too warm
change of biorhythms
hearty dinner
unstable metabolism, etc.

In newborns and premature babies, a temperature of thirty-seven degrees in the evening is not uncommon and is associated with the formation of normal thermoregulation processes in the infant's body.
Such reasons are the most common and all parents face.

The children's nervous and vascular systems are not yet fully formed, so they react very quickly to any change in the external or internal environment.

An overly sensitive child may have a fever even when crying heavily or watching an interesting movie.

The baby's digestive system can also respond with an abundant release of enzymes and active intestinal work, which causes the temperature to rise in the evening to 37.

Therefore, the temperature of children is measured only after special training. The thermometer should be installed at the same time under the same conditions.

Sufficient time should pass after the cessation of all activity, the child should be calm and relaxed. The baby's armpit should be allowed to dry completely, and he should not be allowed to sweat himself. It is advisable to measure the temperature before dinner and water procedures.

Eating

Another physiological reason for the increase in thermometer readings is the meal. It is recommended to measure the temperature no earlier than half an hour after a meal. The fact is that while eating, the body spends heat, so it constantly compensates for it.

A noticeable increase in temperature occurs in people with a good metabolism. Most people do not feel these changes, but if you take your temperature right after eating, you will be very surprised.

Since a more voluminous meal occurs in the evening (dinner), then the temperature increase at this time of the day becomes more pronounced.

Overwork

It is known that at night the thermometer readings become much lower. This is facilitated by a decrease in activity and low energy consumption. However, in the evening, the figures, on the contrary, become higher. This happens due to overwork, overexertion, stress.

There is such a thing as chronic fatigue syndrome. In people with this diagnosis, the temperature can rise for no reason throughout the day.

Most often in the evening there is a temperature of 37-37.2 and weakness, headache. If during rest and deep sleep the indicators do not become lower, then you should think about the presence of a pathological cause of this condition.

Reasons for the rise in temperature

Not always, when a thermometer records thirty-seven, it only speaks of harmless functional reasons. Often, such figures indicate the development of a disease.

Such surges may be the first symptom:

Helminthiasis
inflammatory process in the body
introduction of infection
development of malignant neoplasm
cardiovascular disease
allergies
neurological diseases
rheumatism
arthritis
endocrine diseases
development of mental pathologies

When an increase in body temperature is recorded in the evening, the reasons can be very different. They are capable of being associated with intoxication with cellular decay products, the fight against pathogenic microorganisms or impaired neuromuscular conduction.

Infection with infectious diseases is also possible, so a visit to a doctor in this case is mandatory.

Pathological conditions

If a person's temperature rises to 37 in the evening, then this may be a wake-up call. There are many pathological reasons for this condition, but they usually all have additional signs. Busy people with active lifestyles may not even notice them.

Colds

The most common symptom of a cold is precisely an increase in temperature values. In this way, the human body is trying to cope with the causative agent of the infection. It is known that viruses die at a temperature of 38 degrees. Therefore, the temperature should not be brought down to 37. Let your body clear up the infection and build up immunity on its own.

Consequences of infection

Many infectious diseases occur with fever. But what if you are already healthy, and it continues to rise? Such an outcome is also possible. It is in the evening that an increase in thermometer values is noticeable.

Especially often, such symptoms are due to chickenpox, acute intestinal infection, bacterial pathologies. Do not worry, the body will recover its strength in the near future. Such temperature indicators do not require the use of antipyretics. After a night's rest, they bounce back on their own.

Arterial pressure

Hypertensive patients often complain that they have a high body temperature. Such a natural consequence of high blood pressure cannot be called natural, but it is not entirely correct to consider it pathological. As soon as the patient brings blood pressure back to normal, the thermometer shows smaller numbers.

Hypotonic people, on the other hand, have. For some people, it drops below the 36-degree mark. It is very important not to miss the moment here. But if this condition does not cause discomfort, then you can not try to fix it.

VSD

This abbreviation stands for vegetative vascular dystonia. Until now, this disease remains not fully understood.

Many doctors refute it, saying that a person is dealing with chronic fatigue syndrome. One way or another, with vegetative vascular dystonia, an increase in thermometer readings occurs. A person can note that the temperature is 36 in the morning and 37 in the evening.

Oncological pathologies

It is the evening rise in thermometer values that often makes a person turn to specialists. During the examination, tumor processes can be detected.

Benign neoplasms often do not make themselves felt like a symptom. But the multiplication of cancer cells affects the lymphatic system, so a slight increase in the indicators of a mercury meter is the first alarm bell.

Immune diseases

Any deviations in the work of the immune system and the protective functions of the body affect the temperature values. They become higher with the following pathologies:

allergy;
rheumatic diseases;
blood pathology;
systemic deviations.

Many diseases develop due to the increased immune function of the body, which provokes inflammation of a different nature.

What is subfebrile condition, and how to deal with it?

Subfebrile condition is called an unreasonable increase in the temperature values of the human body. In such cases, the indicators do not exceed 37.5 degrees.

The temperature lasts for months or even years. This distinguishes it from the course of acute pathological diseases or physiological reasons for the increase.

The main sign of subfebrile condition is that a person has an elevated body temperature. This disease accompanies:

increased fatigue;
drowsiness and weakness;
decreased appetite;
redness of the skin;
disorders of the digestive system;
increased sweating;
fast pulse;
neuroses and insomnia.

Both a specialist and the patient himself can diagnose the problem in advance. But with subfebrile condition, more research is needed. To do this, consult a doctor and find out why the temperature rises to 37 in the evening.

Diagnostics for subfebrile condition

Before making a diagnosis, a specialist must examine the patient. The state of the mucous membranes, the work of the respiratory system is studied, the organs of the abdominal cavity are palpated.

Defects of joints, lymph nodes are revealed. In women, a gynecological examination and palpation of the mammary glands are performed, the menstrual cycle is studied. The collection of anamnesis is carried out in several stages.

The doctor determines the following:

whether there were surgical interventions or injuries in the recent past (in women - childbirth and abortion);
what infectious diseases were transferred during life and whether there are chronic pathologies (special attention is paid to diabetes, HIV, liver and blood diseases);
the possibility of hepatitis and bacterial endocarditis.

Such a survey, in general terms, will allow the doctor to get an idea of the person's condition. After that, he will measure his body temperature and blood pressure, perform percussion and auscultation.

Usually, already at the stage of examination, a specialist is struck by a rash on the body, discoloration of the skin, uncharacteristic discharge or formations.

Therefore, to confirm his hypothesis, he prescribes a number of tests showing the state of the blood picture, the possible presence of severe infectious chronic diseases or helminthic invasion.

For this, the specialist will send the patient for laboratory tests.

To clarify the reason why he always has a temperature of 37 in the evening, you need to go through:

clinical and biochemical blood test
four mandatory tests (HIV, syphilis, hepatitis B and C)
allergen panel
general urine analysis
analysis of feces for eggs, worms and protozoan cysts
sputum microscopy
discharge of the urethra and genitals
biopsy
spinal cord puncture.

The results obtained help to identify helminthiasis, inflammatory processes or allergic reactions.

For the purpose of differential diagnosis, it is also necessary to do fluorography, radiography, ultrasound scanning, ECG, EEG, CT, MRI, as well as conduct special targeted studies. All this quickly allows you to identify tuberculosis, diseases of the heart, blood vessels, liver and kidneys, malignant neoplasms, which often cause an increase in temperature in the evening.

The specialist receives the final confirmation of the diagnosis by conducting instrumental studies. For this, mammography, FGDS, angiography, ultrasonography, etc. are used.

They accurately enough allow to identify the disease, due to which there is a regular rise in temperature, as they show the state of the patient's internal organs. In addition, they allow the general picture of the disease to be correlated with an altered thermal regime.

Fever is a sign of illness in any case, even if there are no typical visible signs

general information

The mechanisms responsible for maintaining a certain temperature range ensure the smooth operation of all functions of the human body. They also regulate the rate of heat exchange. Thermoreceptors located on the skin track information about the external temperature. The control of internal indicators is carried out by central thermoreceptive neurons. If the setting mode is violated, then the response to the corresponding signals is specific reactions aimed at resuscitation of adequate indicators. This is done through the endocrine and somatic systems.

Note! There is no single definition of the temperature norm. In many healthy adults, it ranges from 36 to 37.5 degrees.

Temperature character

In an adult, an increase in temperature is a consequence of the production of pyrogens. Some of these proteins are found in the body. They can also be components of the microbial cell and come from the outside. In order to find out why the temperature rises without cold symptoms in an adult, you need to clarify its nature. He can be:

The main reasons for the increase

For the wrong temperature, no patterns are characteristic. It rises with tuberculosis, endocarditis, sepsis. With the inverse type, the indicators may increase in the morning, and decrease in the evening. This is typical for brucellosis.

If the temperature "jumps" for 1-3 days, then it is called recurrent. The causes of this condition can be associated with relapsing fever and malaria.

With a wavy type, the indicators rise gradually and last for several days. Then the temperature drops and then rises again. This happens with typhoid fever, lymphogranulomatosis.

The hectic type is characterized by fluctuations in indicators within 2-3 degrees. The next day, she bounces back on her own. This sign signals that a person has serious purulent foci.

With a laxative temperature, fluctuations in indicators are 1-1.5 degrees / 24 hours. They do not come back to normal on their own. This happens with focal pneumonia and purulent diseases.

In the intermittent type, the temperature is first high, then normal and low. This could be due to malaria. A constant temperature is kept with pneumonia.

Reasons for raising to 37 degrees

Indicators may increase against the background:

severe fatigue;
depression;
emotional burnout;
the development of a sluggish infection;
decreased immunity;
bearing the fetus.

Sometimes an increase in temperature can be associated with a pre-cold condition. Often this symptom speaks of such serious venereal pathologies as AIDS and syphilis.

Also, the temperature rises due to the fact that the human defenses are actively fighting infection.

Reasons for raising to 38 degrees

Temperature 38 without symptoms in an adult is observed against the background:

alcohol intoxication;
reactions to vaccinations;
allergies;
digestive upset;
hyperthermia;
regular severe stress;
physical overwork.

If the temperature lasts longer than 72 hours and continues to rise, then the reasons may be associated with an infarction state or the progression of inflammation in the tissue structures of the cardiovascular system. Sometimes this sign signals that nervous regulation has been disrupted in systems and organs.

If a temperature of 38.5 lasts for several weeks or months, this may signal the growth of a tumor or the course of an endocrine disease. At the same time, nonspecific signs such as hair loss, sudden weight loss and constant weakness may appear.

Reasons for raising to 39 degrees

If the temperature rises to 39 degrees and lasts a long time, this may indicate the development of febrile fever. Other reasons for its increase include:

the course of tumor processes;
meningococcal infection;
infective endocarditis;
catarrhal tonsillitis.

Temperature 39 is often provoked by a malfunction in the system of the subcortical center of the brain.

Note! This condition can last for several years. Sometimes the body adapts to it.

Sometimes this symptom signals inflammation in the renal pelvic system. The temperature can last for a very long time.

If the numbers rise sharply to 40 and rise above, this indicates hectic fever.

When it's not dangerous

Sometimes the answer to the question of why the temperature lasts can be quite harmless. The upward change in indicators is observed against the background of:

overheating;
emotional or mental fatigue;

In people suffering from neuroses, the temperature often "jumps" and returns to normal on its own.

Changes in indicators are observed in children. This is especially true for boys. A syndrome appears, which is defined in medicine as "growth temperature". The child grows up, this process is accompanied by a powerful release of energy. The increased temperature does not affect well-being.

When it is very dangerous

An increase in temperature without symptoms can signal dangerous conditions such as:

the growth of a malignant neoplasm in the liver;
swelling of the stomach;
development of lymphosarcoma;
kidney tumor;
colon cancer;
pancreatic tumor.

The activity of tumor cells is accompanied by the release of pyrogenic substances. They provoke the development of fever. The temperature rises in degrees. This condition is accompanied by symptoms such as aches throughout the body, vague headaches, nausea, and stool disorder.

Increased performance when taking medications

A sudden increase in indicators can be triggered by the use of certain drugs. This usually occurs after five days. The main drugs provocateurs include:

Cardiovascular drugs.
Antihistamines
Iodine medicines.
Anti-inflammatory drugs.
Antibiotics

From cardiovascular drugs, an increase in temperature is caused by Hindin, Alpha methyldol. From anti-inflammatory - Ibuprofen, Tolmetin. From antibiotics - Isoniazid, Cephalosporin, Penicillin, Tetracycline.

Other pathologies

The temperature can vary from 37 to 39 degrees due to the development of:

vasculitis;
Crohn's disease;
rheumatic fever;
Still's disease;
rheumatoid arthritis;
lupus erythematosus.

This condition is accompanied by aches throughout the body. Fever, which accompanies an increased temperature, often indicates a vascular pathology of the legs. The most commonly diagnosed deep vein thrombosis or thrombophlebitis.

If the temperature readings increase after injury, this may indicate the development of pulmonary embolism.

What to do

If the high temperature persists for several days, you should visit your therapist. The doctor undertakes to refer to:

Advice! You can not thoughtlessly take antipyretic drugs. After getting rid of the symptom, there is a risk that the disease will be neglected. This can lead to unpredictable consequences. If the indicators rise very strongly, then you need to call an ambulance. Depending on the patient's state of health, a decision may be made on hospitalization.

When to shoot down

A safe threshold for adults, at which the temperature does not go astray, is 38.5 degrees. If it grows, then there is a serious danger to the endocrine and cardiovascular systems. When this condition is observed for a long time, a force majeure situation arises. Brain activity suffers. If the fever is very strong, the person may become delirious and have seizures. An exacerbation of chronic pathologies is observed.

Note! At 42 degrees, irreversible consequences occur in the cerebral cortex. Against this background, the patient dies. But such cases are quite rare.

Than to shoot down

If the indicators are growing rapidly, then you can normalize them using:

Rheumatoid arthritis and rheumatic fever are treated with salicylates and glucocorticoid drugs.

What else can be done

The elimination of the "temperature tail" with thermoneuroses is eliminated by gentle sedatives. The passage of psychotherapy sessions is prescribed, massage manipulations are carried out. Attending choreographic classes contributes to recovery.

Acupuncture is of great benefit to the body. Care should be taken with herbal medicine. This is especially true for those people in whom the increase in performance was caused by an allergic reaction. Some herbal medicines can aggravate the clinical picture.

It is also necessary to establish a sleep and nutritional regimen. You need to sleep at least 8 hours. Spices, salt, alcohol should be excluded from the menu.

Finally

In order for the temperature not to rise for no reason, it is necessary to be examined regularly. This will help avoid serious health problems.

Why does the body temperature keep 37 for a long time

The rise in temperature indicators to low values is quite common. This can be a manifestation of both various diseases and be considered the norm. What if a person has a temperature of 37 degrees?

Causes of low-grade fever

A body temperature of 37 degrees can be kept for several days or even a week. But why does it hold on to such values?

It is customary to distinguish several causes of an infectious nature in the form of:

viral or bacterial infections of an acute nature;
chronic inflammatory process;
the development of tuberculosis or HIV infection;
the occurrence of viral hepatitis.

If the temperature lasts 37 for a week, the reasons may be:

the appearance of tumor-like formations;
thyroid disease;
blood disease in the form of anemia;
Crohn's disease;
ulcerative colitis of nonspecific form;
ankylosing spondylitis;
rheumatism.

The causes can also be psychogenic in nature or act as a tail after a previous illness.

Infectious causes

Most often, temperature indicators increase with a cold. In this case, other symptoms arise in the form of:

nasal congestion;
difficulty breathing;
runny nose;
dry type cough or sputum discharge;
rashes on the skin.

Some childhood illnesses are mild. These include chickenpox or measles.

With a long presence of focal infection, the symptomatology is gradually erased and becomes habitual. Therefore, the only sign of an unfavorable condition is low-grade fever. In such a situation, it is rather difficult to find the cause on your own, so the help of a specialist is required.

A long rise in temperature can be observed when:

ENT diseases in the form of tonsillitis, sinusitis, otitis media, pharyngitis;
dental diseases in the form of carious formations;
diseases of the digestive system in the form of gastritis, colitis or pancreatitis;
inflammatory diseases of the urinary system;
inflammatory processes in the female and male genital organs;
an abscess at the injection sites;
long non-healing ulcers in elderly patients and patients with diabetes mellitus.

If a person's temperature rises to 37 degrees constantly, then the doctor will ask for an examination, which includes:

general analysis of blood and urine;
consulting with narrow specialists in the form of an otolaryngologist, gastroenterologist, dentist, gynecologist;
conducting computed or magnetic tomography;
ultrasound diagnostics;
X-ray examination.

A constant temperature may indicate other pathologies. But they are diagnosed much less frequently.

Toxoplasmosis is considered very dangerous when the first infection occurs during gestation. Such a process threatens the development of congenital pathologies in the baby. Symptoms are characteristic in the form of a slight increase in body temperature, damage to the optic organ and the digestive system.

Symptoms are manifested in the form of a periodic febrile state, pain in the articular and muscle tissues, decreased auditory and visual function, confusion.

To be checked for the presence of worms, it is necessary to undergo an examination, which consists in the delivery of a general blood test for ESR and eosinophils, analysis of feces for the presence of a worm egg. If an infection is detected, your doctor will prescribe anthelmintic drugs.

Tuberculosis. Many patients believe that this disease is rather rare nowadays. But if the temperature is 37 for a long time, then perhaps the reason lies precisely in this. Most often, this ailment affects healthcare workers, young children, students and soldiers.

Tuberculosis is a bacterial infection that affects the lungs of a person. To diagnose the disease, a Mantoux test and fluorography are taken annually.

The main symptoms include fatigue, weakness, decreased or lack of appetite, a sharp decrease in body weight, high blood pressure, pain in the lumbar region, blood in the urine, coughing and shortness of breath.

Diseases of the endocrine system

Some patients are wondering why they have a temperature of 37 without symptoms? Often the cause is a disorder in the thyroid gland. When the thyroid gland begins to work hard, all metabolic processes are accelerated, which affects the thermoregulation of the body.

If the temperature is 37 without symptoms, then you need to take a blood test for hormones. With a long course of the disease, other signs can be observed in the form of:

increased irritability;
rapid heart rate and high blood pressure;
liquefied stools;
a sharp decrease in body weight;
excess hair loss.

When the diagnosis is confirmed, the patient is prescribed hormone therapy.

Development of anemia

Anemia is a medical condition that is associated with a decrease in the level of hemoglobin in the blood. This condition can be observed for a variety of reasons. But most often the disease is observed in a woman, since it is she who regularly experiences minor blood loss.

In some situations, the hemoglobin level may be normal, but the amount of iron in the blood may be low. This process is called latent anemia.

The signs of this disease are hidden in:

cold hands and feet;
loss of strength and decreased ability to work;
regular headaches and dizziness;
bad hair and nails;
increased sleepiness during the daytime;
itching and dryness of the skin;
regular occurrence of stomatitis or glossitis;
poor tolerance of stuffy rooms;
instability of the stool and urinary incontinence.

If the patient has a temperature of 37 for a month, then you need to undergo an examination, which includes:

donating blood for hemoglobin;
donating blood to the level of ferritin;
examination of the digestive system.

If the patient's diagnosis is confirmed, then the treatment consists in taking ferrous iron in the form of Sorbifer and Ferretab. Along with this, it is necessary to use ascorbic acid. The duration of treatment is three to four months.

Autoimmune diseases

If the indicators are regularly kept at around 37 degrees, the temperature is observed without symptoms for a long time, then perhaps the reason lies in an autoimmune disease.

The most common ones are:

rheumatoid arthritis;
affection of the thyroid gland;
systemic lupus erythematosus;
Crohn's disease;
toxic goiter;
Sjogren's syndrome.

If the body temperature has been kept at 37 degrees for two weeks, then the doctor will prescribe an examination, which includes:

blood donation for analysis by the erythrocyte sedimentation rate;
donating blood for protein;
research for rheumatoid factor;
examination for cells that indicate the presence of systemic lupus.

After the diagnosis of the disease, treatment will consist in the use of immunosuppressants, anti-inflammatory and hormonal medications.

Temperature tail

If the temperature rises in the evening, with no signs of a cold, then the patient may have a temperature tail. It occurs after a cold or flu infection.

The duration of this state usually does not exceed seven days. Therefore, it does not require treatment and goes away on its own.

But the patient after suffering illnesses needs to pay attention to strengthening the immune function. To do this, you need to take vitamins, eat a lot of fruits and vegetables, exercise and temper.

Psycho-emotional reasons

Often after a working day, a person feels weakened both physically and morally. As a result, the temperature rises above 37 degrees. This phenomenon is often observed in young children, women during the period of gestation and breastfeeding, adolescents. All of this is associated with stressful situations and emotional overload.

If no other signs are observed, then it is considered that the state of health is normal. It does not require treatment. It is enough to adhere to a few rules:

ensure adequate sleep for at least eight hours a day;
walk more often in the fresh air;
worry less.

If the patient has an unstable psyche and is experiencing panic attacks, then you should seek help from a psychotherapist. Such people are usually in a prolonged depression and have a fine mental organization.

Subfebrile drug fever

If the temperature lasts for a week, then you should pay attention to what the patient was taking before. This phenomenon is often observed when using:

adrenaline, ephedrine, norepinephrine;
atropine, some groups of antidepressants, antihistamines and anti-inflammatory drugs;
antipsychotics;
antibacterial agents;
chemotherapeutic therapy for tumor-like formations;
narcotic pain relievers;
thyroxin preparations.

With timely cancellation, the temperature readings return to normal.

If the patient has a temperature of 37 degrees for a long time, then you do not need to treat this symptom on your own. It is better to seek help from a specialist. He will listen to complaints and, based on this, schedule an examination. When the cause is clarified, appropriate treatment will already be prescribed.

Low-grade fever: why does the temperature keep 37 for a week?

Body temperature is one of the most important physiological parameters that indicate the state of the body. We all know from childhood that normal body temperature is +36.6 ºC, and a temperature rise of more than +37 ºC indicates some kind of disease.

Danger of increased temperature

What is the reason for this condition? The rise in temperature is an immune response to infection and inflammation. The blood is saturated with temperature-raising (pyrogenic) substances produced by pathogenic microorganisms. This, in turn, stimulates the body to produce its own pyrogens. Metabolism is somewhat accelerated to make it easier for the immune system to fight the disease.

Fever is usually not the only symptom of the disease. For example, with colds, we feel typical symptoms for them - fever, sore throat, cough, runny nose. With mild colds, the body temperature can be +37.8 ºC. And in case of severe infections, such as the flu, it can rise up to + 39-40 ºC, and aches in the whole body and weakness can be added to the symptoms.

In such situations, we know perfectly well how to behave and how to treat the disease, because its diagnosis is not difficult. We gargle, take anti-inflammatory drugs and antipyretics, if necessary, take antibiotics, and the disease gradually goes away. And after a few days, the temperature returns to normal.

Most of us have faced a similar situation more than once in our lives. However, it happens that some people experience slightly different symptoms. They find that their temperature is higher than normal, but not by much. We are talking about subfebrile - about a temperature in the range of ºC.

Is this condition dangerous? If it does not last long - for several days, and you can associate it with some kind of infectious disease, then no. It is enough to cure it, and the temperature will drop. But what if there are no visible symptoms of a cold or flu?

Here it must be borne in mind that in some cases colds may have blurred symptoms. Infection in the form of bacteria and viruses is present in the body, and the immune forces react to their presence by raising the temperature. However, the concentration of pathogenic microorganisms is so low that they are unable to cause the typical symptoms of a cold - cough, runny nose, sneezing, sore throat. In this case, the fever can pass after these infectious agents die and the body recovers.

Especially often, a similar situation can be observed in the cold season, during epidemics of colds, when infectious agents can repeatedly attack the body, but stumble upon a barrier of embattled immunity and do not cause any visible symptoms, except for an increase in temperature from 37 to 37 ,5. So if you have 4 days 37.2 or 5 days 37.1, and at the same time you feel bearable, this is not a cause for concern.

However, as you know, colds rarely last more than one week. And, if the elevated temperature lasts more than this period and does not subside, and no symptoms are observed, then this situation is a reason to think seriously. After all, a constant subfebrile condition without symptoms can be a harbinger or a sign of many serious diseases, much more serious than the common cold. These can be diseases of both infectious and non-infectious nature.

Measurement technique

However, before worrying in vain and running to doctors, you should exclude such a banal reason for subfebrile condition as measurement error. After all, it may well happen that the reason for the phenomenon lies in a faulty thermometer. As a rule, this is the fault of electronic thermometers, especially cheap ones. They are more convenient than traditional mercury ones, however, they can often show incorrect data. However, mercury thermometers are not immune to errors. Therefore, it is better to check the temperature on another thermometer.

Body temperature is usually measured in the armpit. Rectal and oral measurements are also possible. In the last two cases, the temperature may be slightly higher.

Measurement should be taken while sitting, calm, in a room with normal temperature. If the measurement is taken immediately after intense physical exertion or in an overheated room, then the body temperature in this case may be higher than usual. This circumstance should also be taken into account.

One should also take into account such a circumstance as temperature changes during the day. If in the morning the temperature is below 37, and in the evening - the temperature is 37 or slightly higher, then this phenomenon may be a variant of the norm. For many people, the temperature can change somewhat during the day, rising in the evening hours and reaching values of 37, 37.1. However, as a rule, the evening temperature should not be subfebrile. In a number of diseases, a similar syndrome, when the temperature is above normal every evening, is also observed, therefore, in this case, it is recommended to undergo an examination.

Possible causes of prolonged subfebrile condition

If you have an elevated body temperature without symptoms for a long time, and you do not understand what this means, then you should consult a doctor. Only a specialist after a thorough examination can say that this is normal or not, and if it is not normal, then what is the cause. But, of course, it's not bad to know for yourself what can cause such a symptom.

What conditions of the body can cause prolonged subfebrile condition without symptoms:

variant of the norm
changes in hormonal levels during pregnancy
thermoneurosis
temperature tail of infectious diseases
oncological diseases
autoimmune diseases - lupus erythematosus, rheumatoid arthritis, Crohn's disease
toxoplasmosis
brucellosis
tuberculosis
helminthic invasions
latent sepsis and inflammation
foci of infection
thyroid disease
anemia
drug therapy
intestinal diseases
viral hepatitis
Addison's disease

Variant of the norm

Statistics claim that 2% of the world's population has a normal temperature slightly above 37. But if you do not have a similar temperature since childhood, and subfebrile condition has appeared only recently, then this is a completely different case, and you do not belong to this category of people.

Pregnancy and lactation

Body temperature is regulated by hormones produced in the body. At the beginning of such a period of a woman's life as pregnancy, a restructuring of the body occurs, which, in particular, is expressed in an increase in the production of female hormones. This process can cause overheating of the body. Typically, a temperature of around 37.3ºC for pregnancy should not be a major concern. In addition, the hormonal background is subsequently stabilized, and subfebrile condition passes. Usually, starting in the second trimester, the woman's body temperature stabilizes. Sometimes subfebrile condition can accompany the entire pregnancy. As a rule, if a fever is observed during pregnancy, then this situation does not require treatment.

Sometimes a subfebrile condition with a temperature of about 37.4 can also be observed in women who are breastfeeding, especially in the first days after the appearance of milk. Here, the reason for the phenomenon is similar - fluctuations in the level of hormones.

Thermoneurosis

Body temperature is regulated in the hypothalamus - one of the brain regions. However, the brain is an interconnected system and processes in one part of it can influence another. Therefore, such a phenomenon is very often observed when, in neurotic states - anxiety, hysteria - the body temperature rises above 37. This is also facilitated by the production of increased amounts of hormones in neuroses. Prolonged subfebrile condition can accompany stress, neurasthenic states, many psychoses. With thermoneurosis, the temperature usually returns to normal during sleep.

To exclude such a reason, it is necessary to consult with a neurologist or psychotherapist. If you really have a neurosis or anxiety associated with stress, then you need to undergo a course of treatment, since loose nerves can cause much greater problems than subfebrile condition.

Temperature tails

You should not discount such a banal reason as a trace from a previously transferred infectious disease. It is no secret that many flu and acute respiratory infections, especially those with a severe course, lead the immune system to a state of increased mobilization. And in the event that infectious agents are not completely suppressed, then the body can maintain an elevated temperature for several weeks after the peak of the disease. This phenomenon is called a temperature tail. It can be observed in both an adult and a child.

Therefore, if the temperature + 37 ºС and above lasts a week, then the causes of the phenomenon may lie precisely in the previously transferred and cured (as it seemed) disease. Of course, if you were ill shortly before the discovery of a constant subfebrile temperature with some infectious disease, then there is nothing to worry about - subfebrile condition is precisely its echo. On the other hand, this situation cannot be called normal, since it indicates a weakness of the immune system and the need to take measures to strengthen it.

Oncological diseases

This reason also cannot be discounted. Often it is subfebrile condition that is the earliest sign of a tumor that has appeared. This is explained by the fact that the tumor throws pyrogens into the blood - substances that cause an increase in temperature. Especially often subfebrile condition accompanies oncological diseases of the blood - leukemia. In this case, the effect is due to a change in the composition of the blood. To exclude such diseases, it is necessary to undergo a thorough examination and take a blood test. The fact that a persistent rise in temperature can be caused by such a serious illness as cancer makes this syndrome to be taken seriously.

Autoimmune diseases

Autoimmune diseases are caused by an abnormal response of a person's immune system. As a rule, immune cells - phagocytes and lymphocytes attack foreign bodies and microorganisms. However, in some cases, they begin to perceive the cells of their body as foreign, which leads to the appearance of the disease. In most cases, connective tissue is affected.

Almost all autoimmune diseases - rheumatoid arthritis, systemic lupus erythematosus, Crohn's disease, are accompanied by an increase in temperature to 37 and above without symptoms. Although these diseases usually have a number of manifestations, they may not be noticed at an early stage. To exclude such diseases, you must be examined by a doctor.

Toxoplasmosis

Toxoplasmosis is a very common infectious disease that often proceeds without noticeable symptoms, except for fever. It is often a problem for pet owners, especially cats that carry bacilli. Therefore, if fluffy pets live in your house and the temperature is subfebrile, then this is reason to suspect this disease. You can also get the disease through poorly cooked meat. To diagnose toxoplasmosis, a blood test should be taken for infection. You should also pay attention to symptoms such as weakness, headaches, decreased appetite. The temperature with toxoplasmosis does not go astray with the help of antipyretics.

Brucellosis

Brucellosis is another disease caused by an animal-borne infection. But this disease is most often affected by farmers who deal with livestock. The disease in the initial stage is expressed in a relatively low temperature. However, as the disease progresses, it can take on severe forms, affecting the nervous system. However, if you do not work on a farm, then brucellosis can be ruled out as a cause of hyperthermia.

Tuberculosis

Alas, consumption, notorious for the works of classical literature, has not yet become part of history. Millions of people are currently suffering from tuberculosis. And this disease is now typical not only for places not so remote, as many believe. Tuberculosis is a serious and persistent infectious disease that is difficult to treat even by the methods of modern medicine.

However, the effectiveness of treatment largely depends on how quickly the first signs of the disease were detected. The earliest signs of the disease include subfebrile condition without other pronounced symptoms. Sometimes temperatures above 37 ºC can be observed not all day, but only in the evening hours. Other symptoms of tuberculosis include sweating, fatigue, insomnia, and weight loss. To determine exactly whether you have tuberculosis, you need to perform an analysis for tuberculin (Mantoux test), as well as do a fluorography. It should be borne in mind that fluorography can reveal only the pulmonary form of tuberculosis, while tuberculosis can also affect the genitourinary system, bones, skin and eyes. Therefore, you should not rely only on this diagnostic method.

About 20 years ago, a diagnosis of AIDS meant a death sentence. Now the situation is not so sad - modern drugs can support the life of a person infected with HIV for many years, or even decades. It is much easier to get infected with this disease than is commonly believed. This disease affects not only the representatives of sexual minorities and drug addicts. You can pick up the immunodeficiency virus, for example, in a hospital with a blood transfusion, with casual sexual contact.

Constant subfebrile condition is one of the first signs of the disease. Let's note. that in most cases, the weakening of immunity in AIDS is accompanied by other symptoms - an increased susceptibility to infectious diseases, skin rashes, and stool disorders. If you have reason to suspect AIDS, you should immediately consult a doctor.

Helminthic invasions

Latent sepsis, inflammatory processes

Often, an infection in the body can be latent in nature, and do not show any signs other than fever. Foci of a sluggish infectious process can be located in almost any organ in the cardiovascular system, gastrointestinal tract, in the skeletal and muscular systems. Most often, urinary organs are affected by inflammation (pyelonephritis, cystitis, urethritis). Often, subfebrile condition can be associated with infective endocarditis, a chronic inflammatory disease that affects the tissues surrounding the heart. This disease can have a latent character for a long time and not manifest itself in any other way.

Also, special attention should be paid to the oral cavity. This area of the body is especially vulnerable to pathogenic bacteria because they can enter it regularly. Even a simple, untreated tooth decay can become a hotbed of infection, which will enter the bloodstream and cause a constant protective response of the immune system in the form of a rise in temperature. The risk group also includes patients with diabetes mellitus, who may have non-healing ulcers that make themselves felt through fever.

Diseases of the thyroid gland

Thyroid hormones such as thyroid-stimulating hormone play an important role in the regulation of metabolism. Certain diseases of the thyroid gland can increase the release of hormones. An increase in hormones can be accompanied by symptoms such as increased heart rate, weight loss, hypertension, inability to tolerate heat, deterioration of hair and fever. Nervous disorders are also observed - increased anxiety, anxiety, distraction, neurasthenia.

An increase in temperature can also be observed with a lack of thyroid hormones.

To eliminate the imbalance of thyroid hormones, it is recommended to take a blood test for the level of thyroid hormones.

Addison's disease

This disease is quite rare and is expressed in a decrease in the production of hormones by the adrenal glands. It develops for a long time without any special symptoms and is also often accompanied by a moderate increase in temperature.

Anemia

A slight increase in temperature can also cause a syndrome such as anemia. Anemia is a lack of hemoglobin or red blood cells in the body. This symptom can manifest itself in various diseases, it is especially characteristic of severe bleeding. Also, an increase in temperature can be observed with some vitamin deficiencies, a lack of iron and hemoglobin in the blood.

Drug treatment

At a subfebrile temperature, the causes of the phenomenon may consist in taking medications. Many medications can cause fever. These include antibiotics, especially drugs of the penicillin series, some psychotropic substances, in particular, antipsychotics and antidepressants, antihistamines, atropine, muscle relaxants, narcotic analgesics. Very often, a rise in temperature is a form of an allergic reaction to a drug. This version is perhaps the easiest to check - it is enough to stop taking the drug that arouses suspicion. Of course, this must be done with the permission of the attending physician, since the withdrawal of the drug can lead to much more serious consequences than subfebrile condition.

Age up to a year

In infants, the causes of low-grade fever may lie in the natural processes of the body's development. As a rule, a person's temperature in the first months of life is slightly higher than that of adults. In addition, in infants, thermoregulation disorders can be observed, which is expressed in a slight subfebrile temperature. This phenomenon is not a symptom of pathology and should go away on its own. Although fever in infants, it is still best to show them to a doctor to rule out infections.

Intestinal diseases

Many infectious intestinal diseases can be asymptomatic, except for an increase in temperature above normal values. Also, a similar syndrome is characteristic of some inflammatory processes in diseases of the gastrointestinal tract, for example, in ulcerative colitis.

Hepatitis

Hepatitis types B and C are severe viral diseases that affect the liver. As a rule, prolonged subfebrile condition accompanies sluggish forms of the disease. However, in most cases, it is not the only symptom. Usually, hepatitis is also accompanied by heaviness in the liver, especially after eating, yellowness of the skin, pain in the joints and muscles, and general weakness. If you suspect hepatitis, you should consult a doctor as soon as possible, since early treatment reduces the likelihood of severe, life-threatening complications.

Diagnostics of the causes of prolonged subfebrile condition

As you can see, there are a huge number of potential causes that can cause a violation of the body's thermoregulation. And finding out why it happens is not easy. This can be time consuming and demanding. Nevertheless, there is always something from which such a phenomenon is observed. And a high temperature always says something, usually that something is wrong with the body.

As a rule, at home it is impossible to establish the cause of subfebrile condition. However, some conclusions about its nature can be drawn. All the reasons that cause an increased temperature can be divided into two groups - associated with some kind of inflammatory or infectious process and not associated with it. In the first case, taking antipyretic and anti-inflammatory drugs such as aspirin, ibuprofen or paracetamol can restore normal temperature, albeit for a short time. In the second case, taking such drugs has no effect. However, one should not think that the absence of inflammation makes the cause of subfebrile condition less serious. On the contrary, serious things such as cancer can be among the non-inflammatory causes of low-grade fever.

As a rule, diseases are rarely found, the only symptom of which is subfebrile condition. In most cases, other symptoms are also present - for example, pain, weakness, sweating, insomnia, dizziness, hypertension or hypotension, pulse disturbances, abnormal gastrointestinal or respiratory symptoms. However, these symptoms are often erased, and the common man is usually unable to determine the diagnosis from them. But for an experienced physician, the picture may be clear. In addition to your symptoms, you should tell your doctor about any recent activities you have done. For example, did you communicate with animals, what foods you ate, whether you traveled to exotic countries, etc. When determining the cause, information about the patient's previous illnesses is also used, because it is quite possible that subfebrile condition is a consequence of the relapse of some long-treated illness.

To establish or clarify the causes of subfebrile condition, it is usually necessary to pass several physiological tests. First of all, this is a blood test. In the analysis, one should, first of all, pay attention to such a parameter as the erythrocyte sedimentation rate. An increase in this parameter indicates an inflammatory process or infection. Also important are parameters such as the number of leukocytes, hemoglobin levels.

To detect HIV, hepatitis, special blood tests are required. A urinalysis is also needed, which will help determine if there are inflammatory processes in the urinary tract. At the same time, attention is also paid to the number of leukocytes in the urine, as well as the presence of protein in it. To cut off the likelihood of helminthic invasions, feces are analyzed.

If the analyzes do not allow to unambiguously determine the cause of the anomaly, then studies of the internal organs are carried out. For this, various methods can be used - ultrasound, radiography, computed and magnetic tomography.

A chest X-ray can help detect pulmonary tuberculosis, and an EKG can help detect infective endocarditis. In some cases, a biopsy may be indicated.

Establishing a diagnosis in the case of subfebrile condition can often be complicated by the fact that the patient may have several potential causes of the syndrome at once, but it is not always easy to separate the true reasons from the false ones.

What to do if you find yourself or your child with a persistent fever?

Which doctor should I contact with this symptom? The easiest way is to go to a therapist, and he, in turn, can give a referral to specialists - an endocrinologist, an infectious disease specialist, a surgeon, a neurologist, an otolaryngologist, a cardiologist, etc.

Of course, low-grade fever, unlike febrile, does not pose a danger to the body and therefore does not require symptomatic treatment. Treatment in such a case is always aimed at eliminating the hidden causes of the disease. Self-medication, for example, with antibiotics or antipyretics, without a clear understanding of the actions and goals is unacceptable, since it can not only be ineffective and blur the clinical picture, but also lead to the fact that the real ailment will be neglected.

But from the insignificance of the symptom does not follow that it should be ignored. On the contrary, subfebrile temperature is a reason to undergo a thorough examination. This step cannot be postponed until later, reassuring yourself that this syndrome is not dangerous to health. It should be understood that serious problems can be behind such a seemingly insignificant malfunction of the body.
