What is Allergy?

Well, an allergy is nothing but an exaggerated reaction which our immune system gives in response to exposure to specific foreign substances. The response is harmful as normally these foreign substances are usually seen by the body as harmless and non-allergic individuals do not produce a response. The body recognizes the foreign substance in case of allergic individuals and one arm of the immune system generates a response.

If you want to gather knowledge about allergy, then you need to know that allergens are the substances which are foreign to the body and are able to cause an allergic reaction in certain people. If any individual is allergic and he/she comes in contact with any allergen, then his/her immune system will generate a response via antibody. So those people who are prone to allergies are called atopic or allergic.

The allergy symptoms include the nose, eyes, lungs, gastrointestinal tract and skin. Though the various allergic diseases and signs of allergies may appear different, but they all result from an irregular immune response to foreign substances in sensitive individuals.
