Skin allergies: causes, symptoms, treatment. How to treat skin allergies in adults and children

The appearance on the human body of various changes in the skin indicates the presence of a malfunction in the body, expressed most often in a rash in case of allergy to any internal or external stimuli. What a rash looks like with allergies, the photo is presented below.

As a rule, the rash has an extensive or local character, in the first variant they can cover the whole body, while in the second they can focus on certain areas, etc.

Body rash is the most common form of allergy. It can appear completely unpredictable and quickly spread over the skin. At the same time, a person feels, as a rule, itching and burning, and the affected areas first begin to get wet, and over time they become covered with a crust and begin to peel off.

Among the main reasons for the manifestation of allergies - a rash on the body, is the consumption of a number of foods that act as irritants for immune system:

fruit;
Strawberry;
red apples.

These foods often cause rashes in children with allergies. To neutralize the consequences, it is usually enough just to remove these products from the diet and drink antiallergic ones.

Allergies and skin rashes are often caused by sensitivity to the pollen of certain plants, especially in spring... Such people need to start taking drugs in advance to reduce the effect of the reaction as a preventive measure.

Skin allergies usually cause the same general weakness, swelling in the eye area and lack of appetite. How an allergy manifests itself, a rash on the body, the photos clearly demonstrate this.

Rash all over the body

Hand rash allergies are most often caused by prolonged and frequent contact with chemicals. Often they are household detergents for the bathroom, kitchen or toilet and contain chlorine and other active ingredients... If the cause of the rash and redness lies in this, you should always use rubber gloves so that the funds do not get on the skin.

It can also occur due to weather changes, when, when exposed to the cold and for a long time in the open air, the skin of the hands becomes dry, cracked and thinned. Therefore, it is necessary to wear warm gloves and carry with you nutritional composition that does not contain water.

The manifestation of a rash on the hands

Allergy in a rash on the face is one of the most unpleasant manifestations of it, because the face is an open part of the body, which is always in sight. It can arise as a reaction to components in decorative or ordinary cosmetics, although in other cases the reason may lie in the use of food products. What does a rash look like with an allergy on the face? It can be a rash, and redness of some areas of the skin, and the appearance of blisters, and peeling - in this matter, much depends on the individual intolerance of the human body and its corresponding reaction to such an irritant.

Allergies, rashes on the body: treatment

To find out what is causing the symptoms of allergy, consult an immunologist. An analysis is done to select the correct treatment method. Having made special, the specialist will determine what exactly you have such reactions of the body to.

No need to self-medicate without identifying the reasons. Such manifestations as itching, rash, redness are a painful reaction of the immune system to some substances.
Having eliminated the cause of the manifestations, it is possible to achieve a quick relief of the symptoms of the disease and a long-term remission of the allergic disease.

The use of certain drugs for allergies can cause drowsiness, weakness, so the doctor in some cases prescribes the intake of some kind of medication in combination.

First generation allergy medications:

... Serves to eliminate symptoms of urticaria, itching, atopic dermatitis. The downside is that the drug does not accumulate in the body, which is why the effect is transient.
Peritol. Relieves not only the manifestations of allergies, but also helps with migraines, headaches and improves appetite. Treats allergies caused by reaction to cold.
... Effective in eliminating signs of allergies. Its signs disappear - cough, vomiting, redness of the skin. It should be noted that it causes dryness of the mucous membrane, drowsiness and urinary retention.
... Cope with redness and itching without problems.

Second generation drugs:

... The properties and duration of action are closer to those of the first generation drugs. It differs in that the sedative effect is less pronounced.
... It is perfectly excreted from the body by the kidneys, is effective, penetrates the skin and copes well with the manifestations of allergies.
... Combines well with other drugs. Does not cause drowsiness. Allergy symptoms disappear. An excellent tool.

Alternative medicine

There is also a mass folk methods allergy treatment. But we must remember that they must be applied carefully. Herbs and roots can be harmful if the correct proportions are not observed.

Traditional medicine recipe for dust allergies:

Add to them 1 tablespoon of corn silk, 4 tablespoons of St. John's wort, 5 tablespoons of centaury, 1 tablespoon of chamomile, 2 tablespoons of horsetail. Put 1 tablespoon of the resulting mixture overnight in a glass of cold water.
Insist until morning, then bring to a boil, then cool and strain. The infusion is stored in a cold place, taking 1/3 cup from dust allergy 3 times a day. As the intake of this remedy is started, indurations will appear. They must be lubricated with menovazin. A noticeable effect will come within a month. Reception of the infusion must be continued for six months. Drinking alcohol during this period is not advisable.

V Lately allergies are more and more common.

Usually, this disease affects people who have a hereditary predisposition or certain malfunctions in the immune system.

For treatment to be as effective as possible, you need to know what types of allergies exist.

What are the allergens

The cause of the development of the disease is the body's immune response, which is provoked by a variety of substances.

These include the following:

house dust;
Food;
animal hair and particles of their epithelium;
pollen of plants;
mold or mildew spores;
insect bites;
individual medicines;
latex;
household chemicals.

The mechanism of the reaction

People who are prone to allergies perceive absolutely safe substances as antigens. When they enter the body, an increased amount of IgE begins to be released. Once the allergen is identified, this immunoglobulin binds to basophils and mast cells.

The complex, which includes basophils, can enter the nose, lungs, digestive tract, and skin.

At the same time, mast cells, penetrating the organs, retain their immobility.

When the allergen re-enters the body, these cells will release histamine.

It represents a special Chemical substance aimed at eliminating the allergen.

Histamine provokes capillary dilation, smooth muscle spasms, edema and blood clots. As a result, the body reacts to the presence of an allergen in the blood.

Types of allergies and their symptoms

There are many types of disease that have characteristic symptoms.

Respiratory

Such an allergy appears as a reaction of the body to house dust, strong odors and plant pollen. The manifestations of this disease affect exclusively the respiratory system.

Pathology develops as a result of exposure to external and internal allergens, in more rare cases it is provoked by infectious factors.

The severity of the symptoms is influenced by the sensitivity of the respiratory system and the depth of exposure to the allergen.

The clinical picture of the respiratory form of the disease includes the development of:

Constant exposure to an allergen can lead to bronchial asthma.

To make a correct diagnosis, the doctor must study in detail clinical picture illness and family history. The definition of provoking factors is of no small importance.

Contact

This type of allergic reaction occurs as a result of direct skin contact with food or household chemicals.

It manifests itself in the form of development:

The characteristic symptoms of the contact form of pathology are:

This is the most common type of allergy - according to statistics, about 90% of people react to the consumption of certain foods. Most often, the appearance of problems is provoked by foods such as citrus fruits, eggs, sweets.

Food allergy manifests itself in the form of:

Sometimes there are more serious violations- these can be changes in blood or problems in work digestive system.

To identify a disease and establish an allergen, it is recommended to conduct skin tests, keep food diaries, and perform provocative tests that provoke an immune response when exposed to certain allergens.

This type of disease manifests itself in the form of the body's reaction to insect bites. Also, the penetration of their metabolic products into the respiratory system can become a provoking factor.

The reaction to bee, hornet or wasp stings is characterized by worsening general condition... A person may experience weakness, dizziness, and a drop in blood pressure.

Also, local reactions often occur in the form of tissue edema or urticaria.

If the inhaled air contains insect particles, the person may develop signs of bronchial asthma. In especially severe cases, the patient is faced with anaphylactic shock.

Medicinal

Often drug allergy observed in children, and cross-reactions to products and drugs are often formed.

The symptoms of the disease differ depending on the exposure to the allergen. The person may develop hives, nausea, or even anaphylactic shock.

Diagnostics dosage form the disease is not performed, since such tests can lead to extremely negative consequences for health.

In this case, symptomatic treatment is carried out when a reaction of the body appears.

In the future, it is enough to avoid contact with allergens.

Infectious

Such an allergy develops with a high sensitivity to certain microorganisms. For example, there is a reaction to microbes that are part of the Neisseriaceae family.

Under normal conditions, with proper functioning of the immune system, they do not provoke the development of diseases.

If there are malfunctions in the immune system, the person develops symptoms of bronchial asthma.

How does the skin reaction manifest?

It should be borne in mind that there are different kinds skin allergies that have characteristic symptoms.

They possess various forms and in size, creating unusual patterns on the skin of adults. An allergy spot is a flat area of skin.

Similar symptoms are localized in different places, but they do not affect the density or relief of the epithelium.

Red spots on the body are considered the main symptom of urticaria and can occupy a fairly impressive area.

As a rule, they arise abruptly and move throughout the body.

Hives usually last for several hours and then go away.

Also, allergic spots may indicate the development of photodermatosis. In this case, the rash on the body is pink and occurs as a result of exposure to sunlight.

Typically, spots appear on open areas - on the face, legs or hands. In addition, severe itching and swelling of the skin may appear.

Another reason for the appearance of rashes is lichen pink... In this case, a pink rash can be seen on the skin that rises slightly above its surface. The spots are usually oval in shape and are localized on the chest, abdomen, and arms.

Rash in the form of bubbles appear with different types of allergies. Most often, they accompany the development of eczema, dermatitis, urticaria, and the contact form of the disease.

The bubbles usually contain liquid or purulent discharge, they often cause an itching sensation.

Most often similar symptoms appear on the hands, but when certain types allergies spread throughout the trunk.

This is usually characteristic of dermatitis, Quincke's edema, urticaria.

When the bubbles are opened, the mucous membrane of the skin is disturbed, after which the affected area dries up, and a crust forms on it. As a result, pigmentation appears, which disappears after a while.

Blistering allergies usually occur with hives. This disease is accompanied by swelling of a specific area of the skin and an itching sensation.

In addition, nausea, chills, abdominal pain, vomiting, and fever may appear. Headaches often occur and general deterioration well-being.

Urticaria is characterized by the instant appearance of blisters, but after a few hours they disappear in the absence of contact with the allergen.

If such rashes appear regularly, we are talking about chronic form diseases.

Mosquito bites

If the skin rash looks like mosquito bites, this may also indicate the development of allergies. To cope with the problem, you should change your diet.

In addition, such rashes may indicate that a person has been bitten by a mosquito.

Some people have hypertrophied reactions to such phenomena.

Acne on the face can also indicate the development of an allergic reaction. The rate at which symptoms appear depends on the state of the immune system.

Sometimes rashes occur literally 10-20 minutes after exposure to the allergen, but often signs appear after two to three days.

Before acne occurs, there is a slight swelling and redness on the skin. Then, watery pimples appear in this area, which are sometimes accompanied by mild itching.

After that, they burst and leave weeping ulcers. If treatment is not started on time, the threat of infection increases.

In some cases, the rash does not have a watery content. In this case, they are accompanied by flaking and an itching sensation.

It can be strong enough or completely absent. With allergies, acne is usually localized on the cheeks, chin and bridge of the nose.

Why are sorbents needed for allergies in adults? The answer is here.

Hives - what is it and how it manifests itself

This term means a disease that has allergic origin and manifests itself in the form sudden onset on the skin of red spots.

Sometimes hives are accompanied by pale pink blisters. This disease is also characterized by severe itching.

The urticaria got its name because of the similarity of the symptoms of the disease with a nettle burn. The cause of such rashes can be food, household chemicals, insect bites.

Hives are often the result of exposure to cold or heat.

Cross

The main feature of this type of allergy is its high sensitivity to a whole group of allergens that have a similar structure.

Certain substances have a similar set of amino acids, and the immune system reacts habitually to each of them.

This disease is very insidious, since it is very difficult to identify all allergens with a similar structure. Currently, only the most common categories are known.

Cross-allergy has the same symptoms as other types of the disease:

dermatitis;
redness on the skin;
itching and burning sensation;
allergic rhinitis;
hives;
sneezing;
lacrimation;
violation of the stool;
pain in the abdomen;
swelling of the mucous membranes;
sore throat;
vomit;
Quincke's edema.

Complication cross allergies bronchial asthma may appear.

The intensity of the symptoms of the disease depends on the amount of the allergen and the sensitivity of the immune system.

Since it is difficult to identify cross-allergens, the reaction can be very severe.

Forms of complications

If you do not start treating allergies in a timely manner, conditions can develop that pose a real danger to human life.

Quincke's edema

This condition is characterized by the development of allergic edema of the mucous membranes. It can be localized in different organs and occurs in about a fifth of patients.

The main danger of Quincke's edema is that it leads to respiratory failure.

This pathology is characterized by pallor of the skin and the appearance of shortness of breath. During inspection oral cavity you may notice swelling. If you do not provide help to a person in a timely manner, he may die of suffocation.

Anaphylactic shock

This term is understood as an acute reaction that can develop literally within a few minutes.

This condition is characterized by the suppression of some important functions of the body - in particular, a sharp decline blood pressure.

In addition, anaphylactic shock is accompanied by impaired breathing and wheezing. This is very dangerous condition that requires urgent medical attention.

What to do and where to run?

The main goal of allergy treatment is to eliminate the signs of the disease and reduce the hypersensitivity reaction.

For the therapy to be as effective as possible, you need to see a doctor on time. First of all, experts recommend eliminating contact with the allergen.

One of the most effective methods of treatment is allergen-specific immunotherapy. The essence of the procedure is that an antigen is injected into the patient's body in small quantities.

As a result, he gets used to the allergen, and the hypersensitivity reaction disappears.

Also used to eliminate allergy symptoms medications... However, they do not affect the causes of the development of the disease and cannot be used for a long time.

antihistamines- reduce hypersensitivity to allergens and have an anti-inflammatory effect;
stabilizers mast cells - are applied a couple of weeks before the onset of the allergy. If the reaction has already appeared, the desired effect cannot be achieved;
glucocorticosteroids and immunosuppressants- such funds are used in severe conditions. Indications are usually urticaria, bronchial status, anaphylactic shock.

Prophylaxis

To prevent the development of allergies or to avoid the appearance of its symptoms, you need to adhere to some rules.

Allergy prevention includes:

balanced diet. Allergies are often accompanied by pathologies of the digestive system. So good nutrition help reduce the likelihood of illness;
elimination of potential allergens. The development of hypersensitivity is facilitated by house dust, wool, pollen of plants, as well as the use of certain products - honey, chocolate, raspberries. Therefore, it is so important to minimize contact with allergens and do wet cleaning every day;
changing of the climate. If a person has already developed an allergy, an effective way of prevention is to change the environmental conditions;
room humidity control. If the humidity in the room is high, mold can develop, which increases the risk of developing the disease. To avoid such problems, you need to monitor the humidity and regularly ventilate the room.

In order for the treatment of allergies to be as effective as possible, when the first symptoms of the disease appear, you should consult a doctor. Only a specialist will be able to determine the type and form of pathology and select adequate methods of therapy.

Skin allergy photos in adults

What does skin allergy look like in adults? The answer to this question will help you understand what signs you need to see a doctor without delay.

Many allergic dermatoses, other diseases against the background of hypersensitivity of the body are easier, faster and cheaper to treat if you visit a dermatologist and allergist on time. Medical advice will be useful to all patients who pay attention to their health.

Causes of occurrence

Doctors warn patients about two types of negative reactions:

True allergy. Negative symptomatology occurs when the body comes into contact with a foreign protein, which provokes an increased production of immunoglobulin E. In response to the action irritant, against the background of the release of histamine, an immune reaction occurs, signs of allergy appear on the skin. With dermatitis of various kinds, intolerance to drugs, certain types of food, contact with irritating components, mild, moderate or severe symptoms occur.
Pseudoallergy. Red spots, blisters, itching, slight swelling of tissues appears with excessive consumption of foods with high allergic activity. The main difference from true allergies- the immune system is not involved in response to a stimulus. When overeating, not only negative skin signs appear, but also bright disruptions in work digestive tract: diarrhea, bloating, epigastric pain. Pseudo-allergies are often caused by oranges, tangerines, chocolate, eggs, honey. An important condition: a large number of product: half a citrus does not harm, a kilogram of juicy fruit causes negative symptoms.

medicines;
household chemicals;
pollen of plants;
synthetic additives in the composition of products;
stinging insect bites;
heavy metal salts;
animal wool and saliva;
highly allergenic products;
prolonged contact with detergents, oils, disinfectants, solvents at home and at work.

Signs and symptoms

What does skin allergy look like in adults? Symptoms depend on the type of disease, but with pseudo-allergies and an acute immune response, similar symptoms appear.

A visit to a dermatologist and allergist is needed when the following symptoms appear:

peeling, redness of the skin;
severe itching of the skin;
blisters, red spots;
blistering rashes on different parts of the body;
seborrheic crusts;
inflammation, hyperemia in the skin folds;
conjunctivitis;
nasal congestion;
dermatitis, weeping eczema;
swelling of tissues;
discharge of odorless and colorless mucus from the nasal passages;
itching, swelling of the eyelids;
headache;
swelling of the palate, tongue, face, larynx. We need an ambulance call: a severe form of allergy develops - a dangerous angioedema.

Types of skin allergies

Doctors identify several types of skin allergies in adults:

contact dermatitis. Blisters, rashes, redness are the result of the action of toxic substances, household chemicals, washing powder, cosmetic compositions, varnishes and paints;
eczema. A serious illness with a complex of negative symptoms. On the early stage peeling, itching, crusts appear, then weeping develops, serous wells are formed, ulcers, papules appear, the patient feels intolerable itching... During the period of remission, the symptoms are poorly expressed, the skin thickens;
atopic dermatitis more often develops in children of the first year of life, sometimes atopy persists in adolescence and adulthood. The face, elbows, skin folds, knees from the inside are covered with red crusts, itching is felt, a rash is noticeable. One of the causes of the disease is hereditary predisposition. Atopy worsens after the consumption of highly allergenic foods by a baby or a nursing mother. Dermatitis in adults develops upon contact with irritants against a background of weakened immunity, chronic diseases, and digestive problems;
toxicoderma or toxic-allergic dermatitis. The disease develops after taking medication. Main irritants: antibiotics, sulfonamides. Acute reactions are often noticeable, the negative effect of drugs on many organs and systems. The main signs: erythematous rash, erythema on the mucous membranes of the mouth, hands, groin, blisters appear less often. A dangerous form is Lyell's syndrome with a complex of negative manifestations. In the absence of competent therapy, blisters cover up to 80-90% of the body, health worsens, and death is possible;
hives. Red spots or pale pink blisters appear on the skin (with giant urticaria, the convex formations are not light, but purple). Sometimes a rash appears that resembles nettle burns. Skin negative reactions appear suddenly, the body itches, after treatment, the symptoms disappear without a trace.

How to Distinguish Skin Allergies from Skin Diseases

When rashes, redness, itching on the body, face, scalp appear, it is important to remember:

what products were on the menu yesterday / today / last week, how many citrus, honey, chocolate, eggs were eaten these days;
whether potent drugs were prescribed: antibiotics, pain relievers, sulfonamides often cause allergies;
Symptoms may have occurred after a cat or dog recently appeared in the house;
maybe negative reactions appeared after walking next to ragweed thickets, flowering alder, birch or poplar;
whether gloves were used to protect hands when using caustic household chemicals.

So you have to go through all the points about the action of possible allergens (the types of irritants are described in the section "Causes of Skin Allergy in Adults"). Preliminary analysis important for guessing which substance, product, or drug might be causing the negative symptoms. The next stage is a visit to the doctor. At the doctor's appointment, it is important to give detailed answers to each item so that the doctor can assess the clinical picture of the disease.

Causes of advanced cases of the disease

What are the mistakes of patients with cutaneous manifestations allowed most often? How to prevent severe allergies in adults?

many patients in whom the doctor diagnoses eczema, urticaria, contact and atopic dermatitis, neurodermatitis come to see the doctor late, when the disease has turned into chronic stage... One of the reasons is self-medication, the use of homemade ointments, potent, but not suitable for a particular patient, ointments and creams;
for allergies in adults with pronounced skin symptoms, antihistamines are definitely needed ( local funds and pills for skin allergies). Without antiallergic drugs, even the most expensive ointment for skin allergies in adults with a wound-healing, softening effect will not completely eliminate the symptoms. In severe cases, the doctor prescribes a short course of hormonal creams to combat allergic inflammation;
active components of antihistamines suppress the release of histamine, interrupt the chain of negative reactions, prevent the development of an immune response to an irritant;
only when the level of immunoglobulin E decreases, all types of signs accompanying allergic diseases subside. For this reason, when negative symptoms appear on the skin, you should not experience "miraculous" balms and ointments, take herbal baths, take pills on the advice of neighbors or relatives;
only a visit to a dermatologist, consultation with an allergist (according to indications) will make it possible to clarify the diagnosis, prescribe the correct, timely therapy.

Effective treatments

How and how to treat skin allergies? After confirming the diagnosis and the allergic nature of the disease, the doctor prescribes a set of measures. For successful treatment eczema, contact and atopic dermatitis, urticaria, neurodermatitis, ointments or tablets alone are not enough: you need to act on the cause of the disease from the inside and outside, follow a diet, give up some habits. Only with this approach will therapy be effective.

General rules of therapy

Five basic principles of treatment:

Identification of the irritant, refusal of contact with the allergen. If it is impossible to comply with this rule (the effect of cold, UV rays, strong wind, pollen), protect the body: a medical mask, cream on the face and hands, a respirator, filters for the nose.
Hypoallergenic diet for skin allergies. It is allowed to eat foods with a low risk of allergic reactions. Prohibited names: chocolate, fat milk, honey, seafood, citrus fruits, nuts. Not worth eating sea fish, ready-made sauces, pickles, canned food, strawberries, raspberries, tomatoes. Names with artificial ingredients do not benefit: preservatives, emulsifiers, colorants.
Taking a set of medicines. Preparations for external application and oral administration are required. An important element is sorbents that actively cleanse the body.
Refusal from overuse alcohol(it is better not to drink at all during therapy), smoking. Coffee, cocoa, soda, strong black tea are drinks that often cause cross-allergies.
Replacement of household chemicals(powders and aerosols) by means of a gel or liquid concentrate... The absence of volatile allergens reduces the risk of skin reactions. Rubber gloves are needed to protect hands and prevent contact dermatitis.

Medicines

To relieve puffiness, itching, redness, and reduce the area of rashes, doctors prescribe a set of drugs:

antihistamines last generations... Telfast, Claritin, Feksadin, Erius and others, as prescribed by a specialist;
antiallergic drugs of the first generation to combat the signs of Quincke's edema. Fast-acting medicines: Suprastin, Diazolin, Tavegil, Diphenhydramine;
sorbents for removing residues of allergen, toxins, bowel cleansing. Multisorb, White coal, Enterosgel, Polyphepan, Smecta, Laktofiltrum, Sorbeks, activated carbon;
allergy ointments with corticosteroids for severe forms allergies in adults. Prednisolone, Advantan, Elokom, Hydrocortisone, Triderm, Akriderm;
fortifying compounds: calcium chloride, calcium gluconate;
sedatives. Motherwort and valerian tincture, Persen, Novopassit, lemon balm decoction, Karvelis.

Folk remedies and recipes

Useful herbal remedies reduce discomfort against the background of skin symptoms:

Healing baths. Add to the water herbal decoction based on string, chamomile, sage, yarrow, oak bark, calendula.
Lotions on the affected areas with decoctions of the herbs listed in the previous paragraph.

Skin allergy photos in adults

Allergic rash on the skin of a person can manifest itself due to various dermatological diseases, which can be a consequence of an allergic reaction. This is due to the excessive sensitivity of the skin to external and internal stimuli. These irritants are often drugs, food, tissue, pollen, pet dander, and more.

Causes of Skin Allergy in Adults

There are a large number of allergens that can trigger an unwanted skin reaction. This, in turn, is the reason for the development allergic dermatosis.

Many experts believe that the number of allergy sufferers began to increase rapidly due to unfavorable changes in the environmental situation and due to the ingestion of genetically modified products.

In addition, in various cosmetics includes haptens, which can also provoke skin allergies.

Skin rashes can be caused by the following allergens:

Household dust.
Chemistry.
Cosmetics.
Medications.
Food.
Personal hygiene products.
Pet hair.
Pollen.

Mechanism of skin allergy

The main factor in the manifestation of allergic dermatosis is considered to be any allergen- a substance of molecular structure, which is of protein origin.

It happens that allergens can be various elements that do not at all provoke an immune response when entering the bloodstream. Particles that are carried by antigenic determinants are called haptens. These elements can bind to tissue proteins. Haptens are found in medicines and other chemicals.

If an allergen or irritant enters the human body, the development of sensitization begins, which further leads to excessive sensitivity histamine receptors. This action due to the formation of antibodies or the synthesis of sensitized leukocytes.

In most cases skin allergy may be accompanied by itching of varying intensity. The main causes of itching are external and internal allergens.

The body begins to perceive such allergens as dangerous, as a result of which it manifests itself allergic reaction in the form of itching. There are several major cutaneous allergic diseases which may be accompanied by itching. These diseases are described below.

Here you will find in more detail the answer to the question of what to do when the spot on the skin itches with allergies.

Allergic rashes in adults

The appearance and characteristics of skin rashes depend on the type of allergic dermatosis. The rash can appear on a specific area of the body, for example, allergies on the legs, or localized throughout the body.

That is why there are several main types of allergic reactions in medicine:

Atopic dermatitis

Atopic dermatitis is an individual skin disease that is not transmitted by contact. Atopic dermatitis is prone to complications and relapses, so this disease must be constantly monitored, like any other type of allergy.

Symptoms of atopic dermatitis:

Atopic dermatitis can be triggered by the following factors:

Dust.
Insect bites.
Pet hair.
Pet food.
Medications.
Unfavorable ecological situation.
Food.

Skin rashes with allergies (photos are presented below) manifest themselves in several forms: Quincke's edema, eczema, atopic dermatitis, in the form of urticaria.

Skin rash with urticaria

Hives get their name because their rashes are very similar to stinging nettle burns. It has more to do with the symptom than with the disease in its own right.

acute, lasting several weeks;
chronic, lasting can reach several years.
The manifestations of hives on the skin can be affected by both internal and external factors. Some diseases can provoke such a rash ( diabetes, infectious diseases, hepatitis, herpes, gastritis), as well as a weakened immune system and some food.

A rash on the skin with hives (a sign of allergies) looks like small spots or blisters that can be seen in the photo provided. This rash can go away after a couple of hours, and after a while it reappears.

Rash with neurodermatitis

Neurodermatitis is a common skin disease that greatly weakens a person's immune system. Multiple rashes are a hallmark from other types of allergies.

Skin rashes with neurodermatitis (allergies) affect the entire body in the form of small pimples (this can be seen in the presented photos). Over time, nodules appear, which begin to merge into a common spot.

Skin allergy manifestation: symptoms

The first symptom of an allergy is the appearance of a characteristic rash on the skin, and it can occur anywhere. It is possible to damage both only a small area of the skin and the whole body.

An allergic rash is characterized, in most cases, by the sudden onset and rapidity of spread. On the affected areas, characteristic symptoms appear - (see photo), it is also felt strong burning... In this case, it is necessary to prescribe treatment and stop contact with the allergen.

Skin allergy treatment

If there is an allergy to the skin, which is accompanied by red spots that itch, treatment should be started with the elimination of the allergen. Tablets are treated in situations where the reaction makes itself felt quite powerfully.

In such a situation, taking medications is the only way out when skin allergies are tired. The treatment regimen for skin allergies should be chosen depending on whether it will be local or systemic.

For systemic treatment use: antihistamines, cromones and corticosteroid hormones.
For local treatment use: tar preparations, glucocorticoids in the form of ointments, local antiseptics and antibiotics, soothing and moisturizing creams and lotions.

Before starting to treat an allergy, it is, of course, necessary to determine what type it belongs to.

Drug treatment

Drug treatment consists of taking:

(tavegil, fenkarol, suprastin).
Sorbents that absorb excess toxins and remove them from the body (enterosgel).
Local effects - treatment of skin allergies with ointments and compresses
Physiotherapy (electrophoresis, phonophoresis, UV radiation).
Corticosteroids.
Immunomodulators.

The decision on how to treat skin allergies should be made by an allergist with the involvement of related specialists, individually for each case. After the diagnosis is made, he prescribes modern antihistamines, in particular, pills for skin allergies, which are smaller side effects- claritin, zyrtec, loratadine.

Skin allergy ointment for adults

In adults, various ointments for skin allergies are used for topical use.

Bepanten, Lanolin, D-Panthenol - eliminate dryness and improve skin regeneration.
Among the well-known remedies for skin allergies are Fenistil-gel, Gistan cream.

They relieve itching and irritation, redness and other symptoms. However, remember that these drugs are hormonal, so they are used strictly as directed by the doctor.

Diet

In this case, diet is not a temporary change in the diet, but a way of life. As a rule, allergy sufferers know from childhood what foods their immune system reacts to, so they try to observe it throughout their lives.

Very often in childhood, skin allergies in the form of diathesis are caused by citrus fruits, cherries, fish, eggs, etc.

Allergy to the skin is the response of an adult's or a child's body to the action of allergens, the nature of which is quite diverse. Both external and internal irritants provoke the appearance of a characteristic allergic rash, which can appear as spots or dots that have a reddish tint. It is important to start treating the disease from the moment the first negative symptoms appear, acting in a comprehensive manner.

An allergic reaction on the skin manifests itself anywhere - from the face to the legs. Sometimes not local lesion, and the ubiquitous distribution of characteristic spots. It is possible to diagnose a rash provoked by an allergy by the suddenness of its appearance and rapid spread, the presence of additional signs in the form of itching, burning sensation, peeling of the skin and its swelling.

Types and characteristics of skin allergies

An allergic rash can manifest itself in several variants, each of which has characteristic features of its course. The most common forms of skin allergies are eczema, urticaria, neurodermatitis, and atopic dermatitis.

1. Urticaria.

The disease can take one of three forms:

Acute - outwardly, the rash looks like a nettle burn, there is a feeling of severe itching, which is sometimes simply unbearable. Red spots can coalesce into large plaques. When affected by rashes of mucous membranes, attacks of suffocation are possible. The rash sometimes persists on the body for weeks or even months.
Chronic - a rash on the body in the form of red spots lasts about six weeks. At the same time as a rash in adults, Quincke's edema may develop.
Physical - such an allergy on the body in adults becomes the result of regular sweating, cold wind blowing, frostbite or exposure to ultraviolet radiation. Red spots appear immediately after exposure to a negative factor and can persist until the cause of the allergy is eliminated. Often these allergic rashes are seasonal.

Skin allergies are caused by genetic factors. Symptoms such as large red spots or pinpoint rashes (vesicles) can last for a couple of weeks or several months. Formed lesions can not only itch, but also cause pain. In severe cases, watery blisters form. If an infection enters them (upon opening), a serious skin pathology in the form of pyoderma.

3. Contact dermatitis.

It develops through direct contact of the skin and substances or objects-allergens.

4. Eczema.

In adults, such skin rashes with allergies can be determined by the presence of red spots, which look quite rough because of the rough surface. Often, the rash is accompanied by severe itching, and the formed bubbles eventually turn into open erosion, which become wet and flaky. A feature of this type of allergy is the rapid development of eczematous foci, their presence on the hands and face.

5. Neurodermatitis.

With this disease, an allergic rash looks like papular formations (nodules that rise above the skin). Their peculiarity lies in the tendency to merge. Also, doctors consider the main symptom of neurodermatitis to be an increase in unpleasant itching in the area of the rash in the evening. The skin in adults with this disorder looks rough and dry. The places of localization of plaque-like red spots are the neck, the ulnar and popliteal fossa, the tissues surrounding the anus.

Experts identify several types of neurodermatitis, which provoke allergies and itching on the skin. This is a limited (only certain areas are affected) and diffuse (there are extensive foci) forms. Also, dermatographism is referred to the category of allergic reactions that cause changes in the skin. As shown in adults, in this case, red spots appear after trauma to the skin and the appearance of scratches on it. Usually, localized redness is complemented by a rash that looks like hives.

What is the reason for the change in the state of the skin?

Allergy to the skin is a fairly common type of allergic pathology. In terms of prevalence, such a violation is equated to bronchial asthma. They can provoke a negative reaction of the skin various factors, including age, ecological situation, presence chronic diseases(especially often a rash develops against the background of metabolic disorders and pathological deformations in the organs of the digestive system).

Significant external irritants that provoke the appearance of an allergic rash are plants in the flowering phase (daffodils, tulips, geraniums, lilies of the valley and others), food (strawberries, honey, kiwi, yoghurts with additives, sweet curds, juices, fast food), cosmetics and hygiene products, household chemicals. Also strong allergens for some people are synthetic fabrics, animal hair, house dust. If present seasonal allergies, it is worth considering as the root cause of rashes the influence physical factors in the form of cold, sunlight, wind, water.

An allergic reaction that developed against the background of a negative psychological state if a person is exposed nervous disorders, depressed, is overly touchy and impulsive.

Key causes of major allergies

As noted above, the characteristic symptoms of an adult rash determine the type of allergy. Depending on the same criterion, one can single out the reasons, the elimination of which is the main factor in the success of treatment:

1. An allergic rash in the form of contact dermatitis can be provoked by any factors, including mechanical, chemical and biological. For adults, the first group is especially important. A mild course of the disease is often caused by prolonged temperature drops, regular exposure to radioactive or X-rays. When the first signs of rashes appear, extended allergy tests must be done, excluding a negative reaction to household chemicals, paints, plants, food, fabrics.

2. Eczema can provoke both the action of an allergen and genetic predisposition organism, internal pathologies, neuropsychiatric disorders. The most common factor is the effect of hair dyes and cosmetics containing paraphenylenediamine, nickel jewelry, medicinal products intended for external use in the form of ointments, patches. An important place is given to and nervous stress, the course of pregnancy. For example, if the expectant mother had severe toxicosis or lacked adequate nutrition, the likelihood of developing eczema in a child increases significantly.

3. For an allergic reaction in the form of atopic dermatitis, the main provoking factor is poor heredity and a genetically determined disruption of the immune system. In this case, the formation of pathological processes occurs at the stage of intrauterine development.

4. The main cause of urticaria is the presence of increased vascular permeability. As a result of the action of the allergen, edema develops around the vascular structures, which leads to the appearance of a visible allergic rash.

With toxidermia, a feature of which is a rash on both the skin and mucous membranes (including inside the body), doctors consider taking medications and their side effect or influence food allergen... Of the medicines, such a violation is often provoked by drugs of the antihistamine group, which are prescribed precisely for allergies.

The first symptoms of skin allergy

You can suspect a skin lesion with an allergic rash by a number of signs:

Increased dryness of the skin.
Swelling of the skin.
The emergence of uncharacteristic bright points or stains.
Itching sensation.

At the initial stage, most rashes appear as pale red nodules. Sometimes symptoms can be supplemented by an increase in temperature, which indicates a rather severe form of a negative process. It is important to react in time to rashes in children and adults and not to comb problem areas.

To confirm an allergic reaction and plan recovery activities healthy state the skin and the body as a whole, carry out comprehensive examination... The main thing in the diagnosis is the study of the reaction to various allergens (allergy tests). As a rule, when a patient presents with symptoms characteristic of an allergy, doctors conduct a thorough visual examination, assess the presence of chronic internal pathologies and heredity. Skin tests are then ordered and general analyzes urine, blood.

Ways to eliminate skin rashes

For the early relief of an allergic reaction and negative symptoms, first of all, they try to exclude the allergen that caused the negative changes.

It is important to understand that self-medication for any rash is unacceptable, therefore it is imperative to seek medical help for a specialist to plan individual treatment consisting of the following points:

Elimination of symptoms of an allergic reaction. Symptomatic treatment needed to relieve itching and general discomfort. Usually, therapy is carried out using saline compresses.

Local treatment with ointments and creams. Specialty medicines for rashes help in enough short time completely eliminate itching, relieve the burning sensation and return the skin to its natural color. Children and adults can be prescribed Fenistil (in the form of a gel), Bepanten, Advantan, Sinaflan.
Reception of immunomodulators. Based on the general picture of the rash, the doctor chooses a drug of general or local action. Treatment with vitamin complexes that stimulate the immune system may be considered. As a result, the body's defenses are strengthened, which becomes less susceptible to the influence of allergens.
Local immunomodulators in the form of creams or ointments are indicated for application to skin that is sensitive to physical factors.

For maximum effect treatment for rashes, it is important to adhere to the special hypoallergenic diet... To do this, store sweets, red fruits and vegetables, most seasonings and spices are excluded from the diet. Sometimes the ban is even imposed on homemade baked goods.
