THE EAR INSTITUTE OF TEXAS PROVIDES ALLERGY TESTING AND IMMUNOTHERAPY
Allergies are one of the most common chronic diseases. A chronic disease lasts a long time or occurs often. An allergy occurs when the body’s immune system sees a substance as harmful and overreacts to it. The substances that cause allergic reactions are allergens. When someone has allergies, their immune system makes an antibody called immunoglobulin E (IgE). These antibodies respond to allergens. The symptoms that result are an allergic reaction.
AAFA has a lot of information on our site to help you learn more about allergies. Also consider joining a local support group or contacting a regional chapter if one is in your area.

What Are the Symptoms of Allergies?
The most common allergy symptoms can simply make you uncomfortable. For example, you may have watery eyes, runny nose, sneezing, a rash or hives. Other more serious symptoms, like trouble breathing and swelling in your mouth or throat, may be a life-threatning reaction called anaphylaxis (“anna-fih-LACK-sis”).
