An allergy can be broadly defined as an abnormal, adverse, physical reaction of the body to certain substances known as allergens. It is usually referred to as a hypersensitive state because those who suffer from an allergy usually react to quantities of the allergen that leave most people unharmed. The process of how this allergen can cause a problem in the body involves the immune system. Most allergic individuals will develop an excess of the antibody IgE when exposed to an allergen. The IgE antibodies then attach to mast cells (a component of your immune system), and the mast cells cause histamines and leukotrienes to be released from certain other cells, causing the disturbing allergic reactions.
