A bad allergic reaction affects your whole body. Doctors call it an anaphylactic reaction. Your immune system may have reacted to food or medicine. Or maybe you had an insect bite or sting. This kind of reaction can happen the first time you come into contact with a substance. Or it may take many times before a substance causes a problem.
