Allergy causes and symptoms

An allergy is a hypersensitivity of the body to foreign substances. Our defense system (immune system) can usually distinguish between harmless substances, such as foods and hazardous substances, foreign bodies or pathogens. This distinction is necessary in order to combat these dangerous substances and can be rendered harmless. The immune system of some people, however, tends in an excess to be sensitive to certain substances and also even in part harmless for the body substances. That is, even harmless substances such as pollen, are held for a foreign body and trigger an immune response.

Causing

The allergy causing substances are called allergens. In a first contact with these allergens there is no allergic reaction, but the body makes antibodies (repellents) and long lived, so called memory cells against the allergen. With a new contact, it therefore comes to an allergic reaction.
Approx. 80 percent of all allergic reactions take place in the skin or mucous membranes, as this takes place, the main contact with the allergy causing substances.
