Food allergy: symptoms, treatment, photos, causes

Aggressive response( response) of the immune system to certain foods is characterized by the production of chemicals( histomins), causing in the body, this or that, allergic reaction - so is characterized by food allergy.

This indicates an increased sensitivity of the body to certain types of food component directly related to the work of the immune system, when its protein( immunoglobulin "E"), reacting with allergens chemically, causes the appearance of external or internal symptoms.

Failure in immune processes begins at an early age and can adversely affect the operation of many organs and body systems - respiratory and cardiovascular systems, GIT.

Classification of

The reaction of immunity to a food allergen can develop as a result of various factors - when eating, with its odor or even contact.

Food allergy in children and adults is divided into two types - latent and pronounced. The hidden view is dynamic. Regular or excessive use of a provoking product leads to a chronic form of the disease. Excluding it from the diet leads to a rest phase.

The hidden form of food allergy is divided into groups:

1. 1) Year-round - manifested on an ongoing basis throughout the day;
   
2. 2) Leapfrog is a manifestation of an unusual reaction to foods that are not even allergenic, and is expressed mainly by headaches;
   
3. 3) Temperature at which the allergy is manifested even with a slight supercooling of the body, causing an accelerated manifestation of symptoms;
   
4. 4) Complementary, which is a mixed species. Signs of food allergies are exacerbated not only by food products, but also by smells.

A pronounced species is characterized by the manifestation of allergic reactions immediately after ingestion of the allergen product. Allergic reactions in adults are most often manifested when consumed:

• fish products and seafood;
  
• some fruits and berries;
  
• of
  
• eggs of peanuts and various kinds of nuts;
  
• honey and chocolate.

• eggs and carrots;
  
• melon and citrus fruits;
  
• honey, chocolate and coffee;
  
• fish, mushrooms, red berries and many other products.

Causes of food allergy

The development of the disease has its origins since early childhood, and the causes of food allergies are very diverse.

In adults, the reaction manifests itself as a result of:

• hereditary predisposition;
  
• effects of intestinal microflora;
  
• weakened immunity;
  
• hypersensitivity of the gastrointestinal mucosa;
  
• of the regular exposure of the allergen to the body

As for children, the predisposition of the child to allergic reactions is laid even during fetal development and continues right after his birth. And everything begins with the wrong diet of a pregnant woman.

In the future, allergic manifestations develop as a result:

1. 1) Immobilization of antibodies in the body of a child with mother's milk, as a result of improper feeding of the nursing mother;
   
2. 2) Short breastfeeding is the introduction of artificial mixtures, most of which are cooked on cow's milk, the protein of which causes an allergic reaction. If the baby's milk is not enough for the child, hypoallergenic mixtures are chosen according to the doctor's recommendation.
   
3. 3) A large volume of food at the first lure.

Treatment of food allergies

In the treatment of food allergies apply an integrated approach, dividing it into stages. Therapy is aimed at eliminating symptoms, and preventing the exacerbation of the disease. One of the main conditions is to maintain a proper balanced diet.

1. In acute form of the disease, drugs that intensively eliminate symptoms - Suprastin or Tavegil are prescribed.
   
2. With an average and mild degree, the most intense antihistamines are Telfast, Loratadine, Kestin, Cetirasine.

Such drugs do not have "reefs" in the form of side effects, so they are safe and assigned to even the youngest children. If the child suffers from an allergy, it usually manifests as a dysbacteriosis. And the treatment, first of all, is aimed at restoring the physical condition of the microflora.

Sometimes, no medications are needed, just remove the provoking factor from the diet.

Allergen-specific immunotherapy is one of the modern methods of treatment. It is not assigned to adults. It is carried out only in the case when the allergen is vital, and it is impossible to exclude it from the diet. Applies to children who are breastfeeding, but have an allergic reaction to milk.

With any severity of food allergy, you need to see a doctor. Self-medication, of course, can give results, but relapses are not ruled out.
