Why do we have allergic reactions?

Filed under: allergic reactions 

What is it with our bodies that some have allergic reactions to certain things and others don't?

Ex. I'm severely allergic to aspirin.

When your body's immune system senses an "enemy" like a virus, it triggers lots of different actions, including an inflamatory response to help get rid of it. For some reason, certain substances in certain people cause these defenses to falsely react to something. This leads to an inflammatory response, which may be minor, such as sneezing, itching, watery eyes etc. or major, such as swelling throat etc. which can be life threatening. So, basically it is a false inflammatory response. Anti-allergy medicine, such as antihistimines, block these responses from occuring.
