The allergy represents hyper reaction of an organism to influence of certain external factors and irritants which are perceived by it as potentially dangerous.
The answer of immunity to any antigens which intruded in an organism is very difficult and includes development of antibodies which are peculiar defenders of an organism. However there are situations when immunity "runs away" and begins to perceive absolutely harmless antigen as dangerous. At such moments destructive hyper reaction which is shown in the form of an allergy is also started.
Immunity is allocated with remarkable memory therefore if there was the first contact of an organism with alien substance, and the mechanism of development of antibodies for neutralization of antigens was started, then this process (allergy) will repeat at each new meeting with this antigen (allergen).
Potentially practically any substance, and also certain physical factors, such, for example, as the low air temperature or influence of sunshine can become the reason of development of an allergy.
The irritants provoking an allergy depending on an origin are divided into several groups:
All above-mentioned substances become allergens only if in immune system failure is observed, otherwise – they do not cause an allergy.
There are several major factors of risk of developing of an allergy:
This disease can proceed in several forms:
- allergy of respiratory tracts: symptoms of catarrhal diseases are characteristic: transparent allocations from a nose, repeated and frequent sneezing, however are shown they much longer;

- acute anaphylaxis: this form of an allergy is the most dangerous and can be shown in an interval of several seconds till several o'clock (usually to five) from the moment of hit of allergen in an organism. The allergy to medicines or stings of animals which is expressed as follows can be the cause of an acute anaphylaxis: a loss of consciousness, spasms, a sharp otdyshka, vomiting, rash on a body, an uncontrollable urination and defecation. At manifestation of similar symptoms of an allergy it is necessary to call the ambulance immediately.
This type of an allergy demonstrates that on mucous or allergen got to blood and is shown in the form of reddenings and an itch. The allergy on skin is most brightly shown on those sites to which or densely the clothes adjoin, or there is a large number of skin folds.
The allergy on skin can be an effect of food allergy as reaction of an organism to various food stuffs from which are the most potentially dangerous honey, whole milk, nuts, a citrus.
Not only food allergy, but also other types of this disease can cause manifestations on skin, so, for example, pollen, hair of animals, dust, household chemicals, medicines and some types of fabrics can also become allergens.
