Explanation:
Detailed explanation-1: -Allergies are the result of your immune system’s response to a substance. Immune responses can be mild, from coughing and a runny nose, to a life-threatening reaction know as anaphylaxis. A person becomes allergic when their body develops antigens against a substance.
Detailed explanation-2: -Your immune system overreacts by producing antibodies called Immunoglobulin E (IgE). These antibodies travel to cells that release chemicals, causing an allergic reaction. This reaction usually causes symptoms in the nose, lungs, throat, sinuses, ears, lining of the stomach or on the skin.
