What Is an Allergy?
Allergies are an abnormal response of the immune system. People who have allergies have an immune system that reacts to a usually harmless substance in the environment. This substance (pollen, mold, animal dander, etc.) is called an allergen.
Allergies are a very common problem, affecting at least two out of every 10 Americans.
