Causes of Allergy:

The white blood cells present in blood produce antibodies. WBC is responsible for producing antibody specific to the antigen to which the body is exposed. The antibodies detect and destroy the substances which cause the disease. The antibody increases the production of mediators, which is a kind of hormone. This hormone activates more WBC and also affects the local tissues and organs. Sudden allergic reactions are observed when mediators are released extensively.
