al•ler•gy(ˈæl ər dʒi)
n., pl. -gies.
1. an overreaction of the immune system to a previously encountered, ordinarily harmless substance, resulting in skin rash, swelling of mucous membranes, sneezing or wheezing, or other abnormal conditions.
2. Informal. a strong dislike or aversion: an allergy to hard work.
A condition in which exposure to a particular substance or environmental influence, such as pollen, certain foods, or sunlight, causes an abnormal physiological reaction. The reaction may include difficulty in breathing, sneezing, skin rashes, and in severe cases, shock or death.
Did You Know? Feeling miserable because of an allergic reaction? Perhaps you can find some comfort in the knowledge that the misery is an unhappy side effect of your immune system trying to protect you. The immune system recognizes that a particular substance, called an allergen (for example, dust, mold, or pollen), might be dangerous. Antibodies, special molecules whose job is to round up the invaders, charge into action. The immune system, however, can overreact, causing some people to be so sensitive to these outside substances that they develop unpleasant symptoms, such as rashes, runny noses, or even serious illness. People with severe symptoms can get a series of allergy shots that prevent or lessen the allergic reaction by training the immune system to accept the allergen. Oddly enough, many people develop allergies after repeated exposures to an allergen. The difference is that controlled, small exposures through shots prompt the immune system to grow accustomed to the allergen, while accidental, large exposures provoke the allergic reaction.
