An allergy  is something which triggers an allergic reaction. This is the immune system defending the body against attack by bacteria and viruses.

Sometimes the systems goes wrong, and is triggered by some quite normal food, or flares up when the family pet comes into the room. That is what the ordinary person calls an 'allergy'.

They may cough and sneeze. They may develop a rash called hives. Their faces may swell up. If it is a food allergy, the person may get an upset stomach.

When this happens, a doctor must give the person a medicine called epinephrine to make the swelling go down. Some people with allergies to very common things, like bee stings or fish, carry this medicine with them so it can be used quickly in an emergency. The device they use to inject the medicine is called an epinephrine autoinjector.
