What is the hypersensitivity of the body?

Stormy and sometimes unpredictable reaction of the body can cause habitual, at first glance, substances and products. Hypersensitivity is a reaction of the immune system to the effects of various components originating in the body with food, air, on contact with the skin or as a result of medical treatment. The cause of this disease is considered various violations of the body's immune functions. The immune system responds to the penetration of foreign substances by the release of antibodies aimed at neutralizing and destroying allergens. This process is accompanied by the release of histamine with the formation of edema, inflammation and itching of the skin. The severity of the reaction may be mild or of a dangerous nature in the form of a shock state( anaphylaxis).
Allergens can trigger the sensitivity reaction, such as pollen of various plants, animal hair, household dust, flea products, dust mites. Manifestations of reaction to such irritants can be asthmatic attacks and shortness of breath. Foods most often causing an allergic reaction are milk, eggs, fruits, nuts and chitinous shellfish( crabs, crabs, lobsters).Food allergic reaction, as a rule, manifests a violation of the skin( scaling, dryness, redness, contact dermatitis, atopic eczema), but digestive disorders also occur. Contact dermatitis is a consequence of skin hypersensitivity to various irritants( metals, cosmetics, washing powders, rubber, cement mortars).Sensitivity to insect bites( wasps, bees, etc.) and drugs( sulfanilamides, aspirin) can cause a severe reaction of the body, manifested by the onset of anaphylactic shock and damage to cells of the brain, liver, kidneys. The onset of this condition requires urgent medical intervention.

Diagnosis of susceptibility to hypersensitivity and detection of allergens that provoke this condition is performed using a prik test. The supposed stimulus is applied to the previously damaged skin area and the reaction determines whether the substance is an allergen or not. When detecting an allergen, you should avoid contact with this substance in every possible way. Some types of hypersensitivity can be eliminated by taking medications that suppress( reduce) the immune response through the regular administration of minimal doses of the allergen. Severe shock conditions( edema, respiratory spasms) are eliminated by injections of hormonal and antihistamines.
In general, the propensity for a particular hypersensitivity is genetic and is inherited. The state of the environment, social situation and way of life can be attributed to factors affecting the appearance and development of this disease.
