What Are Allergies?

An allergy is your body’s overreaction to something that doesn’t cause a problem for most people. One of the marvels of the human body is its ability to defend itself against harmful invaders, such as viruses and bacteria. With allergies your immune system overreacts by attacking harmless things such as dust, molds, or pollen. The body treats these as invaders and releases chemicals to defend itself. It is these chemicals that cause allergic reactions from mild to severe.
An allergic reaction can affect any part of the body, but its symptoms are most often felt in the nose, eyes, lungs, lining of the stomach, sinuses, throat, and skin,. These are places where immune system cells stand ready to fight off invaders that come into contact with the skin, are inhaled or swallowed. An allergist can work with you to determine what causes your problems and to develop a tailored plan that matches your lifestyle and provides the most effective treatments.
