Allergy is a health condition that arises when you inhale/eat or touch certain substances your immune system is oversensitive to. Allergy may develop relatively quickly, for example you may have eaten shellfish for years with no negative effects, you try it today and oops! You discover that you're allergic to it.

The things that cause allergy are called allergens. Virtually everything might be an allergen, though there are some things that cause it much more often than others.
