Symptoms:
fever, nausea, itching, vomiting, diarrhea, skin rash, abdominal pain
Food allergy is the body's reaction to allergens, received food through. It is able to occur in a large number of cases receiving allergopotentsialnyh products. There are two types:
1. mild;
2. severe.
How does a food allergy
The manifestation of the disease begins a few minutes after a meal. But the probability and a delay of up to 2 hours. In this case, symptoms are less pronounced and not as bright as at the instant reaction to the allergen.
In mild observed following symptoms:
rash as a reddish-pink dots or urticaria;
stuffy nose;
tingling in the mouth;
gastrointestinal disorders;
itchy rash on the body.
In severe marked symptoms such as:
angioedema, covering throat, esophagus, mouth, lips, neck, ears, hair and body parts of the gastrointestinal mucosa;
diarrhea;
intestinal cramps and spasms;
vomiting;
burning;
extensive rashes on the body (abdomen, arms, legs, chest, groin);
strong reddening of the skin;
weakness throughout the body;
dizziness;
coughing and wheezing;
shallow breathing;
distraction or drowsiness.
What causes food allergies
The cause of food allergies - food. In the list of the most common allergens include:
peanuts;
walnuts;
wheat;
soybeans;
shellfish;
shrimp;
fish;
eggs;
milk;
hazelnuts;
almonds.
Usually, the problem is their constituent protein. It is he who makes these products allergens. A person suffering from severe reactions, even quite a smell of food, or touching the product to trigger an allergic response.
Another active allergen - sulfite (a chemical). It is part of the artificially colored food: food, carbonated drinks, some cheap sweets. Also used to make dried fruits and vegetables a bright color.
Food allergies starts with itching, redness of the skin and rashes on the body. They can concentrate on the inside of the forearm, chest, abdomen, in the folds of the joints, on the cheeks and ankles. If there is a mild reaction, then that's about it. However, severe disease manifestation of a more complex, acute and rapid.
In allergy may start swelling of the throat, palate, tongue, abdominal symptoms in the form of swelling of the mucous membrane of the esophagus, stomach, intestines. This in turn triggers diarrhea, vomiting, nausea, choking, wheezing. Such a reaction is called angioedema. It is the most dangerous.
It is noted that the immediate appearance of allergies as a result of the meal proceeds more clearly and problematic, with serious consequences. In case of postponement is less pronounced symptoms and does not cause major problems. In general, the allergic response of an organism depends on the amount of antibody concentrations in the blood.
The most acute manifestations - anaphylaxis. It affects the whole body. As a rule, there is after 1 hour after receipt of the allergen into the body. Able to re-aggravation of 1-2 hours. The most dangerous complications are also observed:
loss of consciousness;
swelling of the throat and tongue (angioedema in the composition);
bronchial asthma;
bronchitis;
eczema;
obstruction of air into the lungs;
coma;
death.
Diagnosis of food allergy
The diagnosis is made on the basis of external characteristics. If the allergen is unknown, appointed special studies:
laboratory tests;
skin tests.
The first list includes:
examination of blood levels of antibodies;
ELISA (enzyme-linked immunosorbent assay);
RAST (radioallergosorbent test).
The second list includes:
prick test (mini-prick with the application of a liquid on the skin to allergens);
provocation test (with false-positive results or blurred symptoms).
Prevention of food allergy
Best option - to refuse a potentially safe food. To do this, you must know exactly what is an allergy and learn to "decode" the labels. Thus, by "kozeinatom" is meant milk, under "hydrolysed vegetable protein" - peanuts under "gluten" - wheat. To prevent overreaction, you should always carry a first aid kit and a special bracelet. It should include all allergens.
