Atopic dermatitis (AD) — a chronic inflammation of the genetically determined skin allergic nature. It may cause a few, and even a lot of factors — allergens enteringorganism baby food (with food), the contact (in contact with the skin and clothing, etc.), or respiratory infections (inhaled pollens, dust).

Atopic dermatitis usually develops in early childhood (most often — in2-3 months) and extends to3-4 years, but may remain for a lifetime.

The risk of developing atopic dermatitis increases with a genetic predisposition to allergic reactions, or if the expectant mother eats a large amount of allergens (such as citrus fruits, strawberries, etc.), especially in the last trimester of pregnancy.

What's going on?

Atopic dermatitis— It is not a disease of the skin. This is a manifestation of internal problems in the child and his immaturity gastrointestinal tract. The situation is as follows. Some fall withinorganism substances are not absorbed: they can not be digested in the intestine, liver neutralized or removed by the kidneys and lungs. These substances from certain transformations acquire properties antigens (foreign substances to the body), and cause the production of antibodies. Complexes antigen-antibody provoke the appearance of the rash.

Another option: Pregnant woman contacted (eating, smeared, breathing) with some "harmful". Eat chocolate, for example. A protein called cocoa appearance of antibodies in the fetus. Later, when thebaby eating chocolate, the antibodies react and rash.

Any allergic rash — a consequence. The reason — the body contact with certain substances which are specifically for this organism are the sources of allergies — allergens.

Allergen has the opportunity to get toorganism three children by natural means:

  1. During the food and drink — food allergies (most common);
  2. With the direct effects of allergen on the skin — contact allergy. For example, skin changes came after the parents of a new baby wash things detergent;
  3. In the process of breathing — breathing or respiratory allergy.

Often I search for the perpetrator of allergy is not possible.

What are the symptoms?

The appearance of the first signs of AD promotes consumption of cow's milk proteins (usually administered mixtures), as well as eggs, citrus, strawberry, strawberry, oats and other cereals. If a baby is breastfed, the diathesis may occur as a consequence of the use of the nursing mother of these products. Less commonly, the rash occurs while wearing clothes laundered with detergent.

Atopic dermatitis proceeds with exacerbations and remissions. Exacerbation of cutaneous manifestations may be caused by a violation of the diet, and the sudden change of weather, comorbidities, dysbiosis, performing vaccinations, etc. At the same time, a trip to the sea can significantly improve the condition of the child.

The most common manifestations of AD are redness, dryness and flaking of the cheeks (redness can be reduced or completely disappear when you exit the cold, and then resume). From a young age, these kids may experience overall dryness of the skin, prolonged diaper rash disappearing into the folds of the skin, especially in the crotch and buttocks. On the scalp formed "milk crust", or gneiss (scales that are glued sebum). Can develop a variety of rashes, itchy nodules filled with transparent content (strofulyus), moist skin.

These children are also characterized by "geographic" language (the language of a plaque, a variety of striated lines), prolonged conjunctivitis, rhinitis. SARS often proceeds at them with obstructive syndrome (problems with the respiratory tract) or false croup (an inflammation of the larynx) can cause problems with the chair (constipation or diarrhea). Body weight often grows unevenly.

By the end of the second year of life, atopic dermatitis usually soften and fade, but some children may develop into a serious allergic diseases such as bronchial asthma, allergic rhinitis. That is why it is important to help little body through this period with minimal risk and get out of this state.
