Severe Allergic Reaction (Anaphylactic Shock) Topic Guide

Severe Allergic Reaction (Anaphylactic Shock) Severe Allergic Reaction (Anaphylactic Shock): The severe reaction of anaphylaxis is an immune allergic response that is life-threatening. The symptoms are breathing problems, shock, or death. Reactions may result from an insect sting or certain foods to which the body has been "sensitized" and has developed a powerful antigen for. Anaphylaxis occurs when the imune system overreacts to the antigen.
