Why anaphylactic shock occurs?

When an allergic person comes in contact to an allergic substance the body's defense system called immune system overreacts to this by releasing specific chemicals that cause allergy symptoms. Some times these allergic symptoms are not so severe and are confined to one location of the body. But in some cases the more susceptible people have more serious anaphylactic reaction and more than one part of the body at the same time.
