Allergies Uncovered ; Your Body's Overreaction

Allergies occur when your body responds to a foreign protein. In some cases, these proteins, known as allergens, are innocuous. But if you're allergic to a specific protein, your body's immune system reacts excessively when it encounters this substance within your body. 
Allergic reaction :  
An allergic response is your body's defense against an allergen.

In the case of allergies, when you are exposed to a specific allergen for the first time, your body initiates a response by generating immunoglobulin E (IgE). The immune system produces these antibodies to create IgE.
IgE antibodies then adhere to mast cells, which are sometimes referred to as allergy cells, distributed in your skin, respiratory passages (airways), and the mucous lining of the interconnected organs spanning from your mouth to your anus, known as the gastrointestinal (GI) tract. This interaction triggers the release of histamine by the allergy cells. Histamine is responsible for allergy symptoms.
