| allergy |
A major defense mounted by the body's immune system against normally harmless substances, or allergens, such as chemicals in pollen, food, bee stings, animal dander, or dust. An allergic reaction is the body's strong reaction to these substances in a person who is sensitive to them. Reactions range from mild to severe, and may include sneezing, a rash, or difficulty breathing (which can be fatal). Allergens trigger allergic reactions in people with allergies.
