Allergies are reactions of the immune system to substances that, in most people, cause no symptoms. Contact with allergens can cause symptoms such as runny nose, sneezing, headache, and more. Allergies affect more than 60 million people in the United States. It is the 5th most prevalent chronic disease in the U.S. among all ages, the 3rd most prevalent among children. Here at Northeast Atlanta ENT, we can test patients for allergies to dust, roach, cat, dog, molds, and a variety of grass, tree and weed pollens. In addition to environmental allergies, we can also test for a large number of food allergies.
