Q: 

What are the causes of allergic reaction?

A: Almost anything can trigger an allergic reaction. The body''s immune system involves the white blood cells, which produce antibodies.When the body is exposed to an antigen, a complex set of reactions begins.The white blood cells produce an antibody specific to that antigen. This is called ''sensitization.''The job of the antibodies is to detect and help destroy substances that cause disease and sickness. In allergic reactions, the antibody is called immunoglobulin E or IgE.This antibody promotes production and release of chemicals and hormones called ''mediators.''Mediators have effects on local tissue and organs in addition to activating more white blood cell...
