Skin Allergies

аллергия на коже фото Allergy on the skin is the reaction of the human body to a certain stimulus, manifested by the sudden appearance on the skin of swollen pale red patches or nodules and their continuous itching. These allergy symptoms are most pronounced in those parts of the skin covers, where clothes are most closely attached to the body or the greatest number of skin folds is present. You should know that in spite of the constant itching of these places, they should not be combed, as this will only worsen the situation. Also, this should not be done due to the fact that through the combs formed during combing, all sorts of pathogenic infections and bacteria can enter the body, which will lead to the development of inflammation. In addition, the wound after healing can leave in its place quite unsightly scars.

Allergy to the skin in children often causes serious itchy skin, and the affected skin can not only itch, but also burn or stove. A rash can appear on any part of the body, even ears, a throat, tongue, lips and face are not insured from it. In its length, the rash can also vary significantly - from an area of ​​a few centimeters to the size of the dinner plate. In addition, the skin rash areas are prone to unification, thereby forming even larger areas of damage. Before the skin rashes on the body begin to gradually fade, must pass at least a few hours or even days.

Angioedevrichesky edema on the symptomatology is very similar to a urticaria. The difference between them is only that the swelling does not develop on the surface of the skin, but under it. Angioedevrichesky edema is characterized by a deep swelling of the skin around the lips and eyes, and in some cases on the feet and hands, and also in the genital area. Most often this disease lasts longer than urticaria, but the tumor usually disappears in less than a day. In severe cases, angioedema of the lungs, tongue, or throat complicates breathing, blocking the airways. In this case, this condition can seriously endanger life

Skin Allergies - Causes

Both the formation of an allergic rash and the development of angioedema are directly related to the immune response of the body to the chemical element histamine, which is emitted through the special cells into the blood vessels of the skin. Insect bites contained in food chemicals, allergic reactions, exposure to medications or sunlight provoke secretion into the skin of histamine. In some cases, the exact cause of the rash can not be established.

The most common skin-affecting allergens include daily household chemistry (spirits, toilet water, deodorants, soap, washing powders, etc.), which are used daily by all, and when contact occurs, the allergen penetrates directly under the skin, causing an allergic rash. For some people, very strong allergens are some natural tissues, especially for wool. The reason for the appearance of skin allergies in children can be made from nickel such items of clothing as buttons, rivets or zippers. Some plants, pet hair can also cause allergic rashes.

The most common food allergens that can cause allergies on the skin include tomatoes, nuts, seafood, chocolate, strawberries, etc. Skin rash may occur as a reaction to certain medications.

The main difference of allergy to the skin from other types of rash is the absence of deterioration in overall well-being. If you specify, then because of an allergic rash in a person there is no weakness, lethargy, the appetite does not go away, but the body temperature does not rise. However, in exceptional cases with a very strong allergic reaction, in addition to the rash, swelling of the lips and eyelids can be observed.

There are many types of allergic rash, below we describe the most common:

• Acute hives. This type of allergic rash is in the active phase for at least six weeks. Its most likely causes are available acute infections, taking certain medications or eating certain foods. Internal diseases and insect bites can also lead to acute urticaria.

Usually an allergy to the skin - a rash occurs due to eating foods such as milk, fresh berries, eggs, tomatoes, fish, chocolate and nuts. An allergic reaction is often provoked by fresh food. Preservatives and certain nutritional supplements of similar effect can also cause.

Capable of provoking angioedevrichesky edema and allergic rash medicines: painkillers (codeine, etc.), non-steroidal anti-inflammatory drugs (ACE, aspirin, ibuprofen, etc.)

• Chronic urticaria and chronic angioedema. These types of rashes last more than six weeks, and the reasons for their development are much more difficult to determine than the causes of acute urticaria. Nearly 90% of people suffering from chronic urticaria have a problem provoking the disease.

Chronic form of angioedema and chronic urticaria affect the gastrointestinal tract, muscles and lungs, manifested by such symptoms as diarrhea , vomiting, difficulty breathing, muscle pain

• Physical urticaria. Allergic rash physical hives appear in case of physical irritation of the skin, which usually occurs as a result of sweating, pressure, exercise, vibration, exposure to sunlight, heat or cold. Symptoms of physical urticaria are usually observed in places where the skin has been physically affected. Most often, these allergic rashes occur after an hour from the moment of irritant effect

• Dermatografism. This type of allergy is a manifestation of scratching or bruising a certain area of ​​the skin and is often combined with other forms of urticaria фото аллергии на коже

Diagnosis of skin allergy is based on a thorough examination by a dermatologist and / or a therapist and on medical history. To identify a specific substance, which could develop an allergic reaction, take skin tests. To establish the possible provoking in the patient allergy diseases, show the delivery of standard blood tests

Skin Allergies - Treatment

To prevent skin allergies, every person susceptible to developing allergic reactions should necessarily know the entire list of allergen-provoking allergens. However, it is often impossible to establish a provocateur for skin rashes on your own. Therefore, with the appearance of the slightest signs of skin allergy, you should not hesitate to consult a doctor. After the appointment of a number of specific tests and analyzes, the diagnosis can be established more accurately, after which the doctor will be able to prescribe an appropriate treatment for the patient.

At the same time I want to note that absolutely no treatment for skin allergy will not be able to help the patient in case the provoking allergen has not been removed from his daily life. In the absence of a provocateur, often an allergy to the skin passes by itself. If this does not happen, the patient is prescribed the use of antihistamines (fenistil, suprastin, tavegil, etc.), which not only remove the skin rashes, but also eliminate the inconvenient itching. In addition, antihistamines are able to eliminate such common signs of an allergic reaction as swelling. In particularly severe cases, the appointment of glucocorticoids is indicated.

Most allergists attribute to their patients hormonal creams and ointment from skin allergies . These drugs are not dangerous at all, as modern creams and ointments contain so little doses of hormones in their composition that they are practically not absorbed into the blood, while having a good antiallergic effect.

Allergy to the skin in children due to the susceptibility of the child's body to hormonal drugs, hormonal creams and ointments is usually not treated. In such cases, funds are used that do not contain hormones in their composition that deal with this problem no less well.
