An allergy is a long term condition in which the immune system mounts an abnormal reaction to an ordinarily harmless substance called an allergen. Allergic reactions vary in severity from relatively minor symptoms to life-threatening.
Allergic reaction[edit | edit source]
An allergic reaction occurs when the person's immune system produces Immunoglobulin E (IgE). When the person comes into contact with an allergen, the IgE travels to cells that release histamine and other chemicals; it is the histamine that causes the allergic reaction.
