An allergy is a hypersensitivity disorder of the immune system. Allergic reactions occur when a person's immune system reacts to normally harmless substances in the environment. A substance that causes a reaction is called an allergen. These reactions are acquired, predictable, and rapid. Allergy is one of four forms of hypersensitivity and is formally called type I (or immediate) hypersensitivity. Allergic reactions are distinctive because of excessive activation of certain white blood cells called mast cells and basophils by a type of antibody called Immunoglobulin E (IgE). This reaction results in an inflammatory response which can range from uncomfortable to dangerous.
Source: WikipediaThe most common causes of allergic reaction are seasonal allergies (hay fever), allergy, and asthma. Other possible causes, such as gastroesophageal reflux disease (gerd), are more rare.
Within all the people who go to their doctor with allergic reaction, 41% report having skin rash, 29% report having nasal congestion, and 25% report having itching of skin.
