What do you mean by Allergy?
Allergy may be defined as a reaction by our immune system to something that does not trouble most other people. It affects a person more specifically.
When a person gets affected by any allergy, the immune system of that person may overreact by producing more antibodies. These antibodies attack the allergen particles and cause adverse symptoms.
