turbulent and sometimes unpredictable reactions of the body can cause the usual, at first glance, substances and products.Hypersensitivity - this is a reaction of the immune system on the impact of different origin components, penetrating into the body through food, air and by contact with the skin or as a result of medical treatment.The cause of the disease are considered different disorders of the immune functions of the body.The immune system responds to the penetration of foreign substances isolation of antibodies designed to neutralize and destroy 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 flow may be mild or carry dangerous nature in the form of shock (anaphylaxis).
hypersensitivity reactions may cause allergens such as pollen of various plants, animal dander, household dust, waste products of fleas, dust mites.Manifestations of reaction to such stimuli may be shortness of breath

and asthma attacks.The foods that most commonly cause allergic reactions are milk, eggs, fruits, nuts and shellfish chitin (crayfish, crabs, lobsters).Food allergic reaction is usually manifested skin condition violation (flaking, dryness, redness, contact dermatitis, atopic eczema), but it does happen and the indigestion.Contact dermatitis is the result of hypersensitivity skin to various stimuli (metals, cosmetics, detergents, rubber, cement mortars).Sensitivity to insect bites (wasps, bees, etc.) and drugs (sulfonamides, aspirin) can cause severe response in the body, manifesting the onset of anaphylactic shock and damage to the brain cells, liver and kidneys.The onset of this condition requires emergency medical attention.
diagnosis of predisposition to hypersensitivity and identification of allergens, triggering a condition made by means of skin prick test.Estimated stimulus is applied to the pre-damaged skin and the reaction is determined whether the substance is an allergen or not.In identifying the allergen must be avoided contact with the substance.Some types of hypersensitivity can be eliminated by administering drugs that suppress (reduce) the immune response through the regular administration of minimal doses of the allergen.Heavy state of shock (swelling, breathing spasms) are eliminated hormonal injections and antihistamines.
In general, susceptibility to certain hypersensitivity is genetic and inherited.State of the environment, social environment and lifestyle can be attributed to factors affecting the appearance and development of this disease.
