What is an Allergy?

Allergies occur when the immune system creates antibodies to attack substances that are not harmful to most people. When this occurs, your immune system overreacts and releases histamines, causing an allergic reaction to particular allergens, such as dust, pet dander, pollen, insects, ticks, foods, and some medicines.
