An anaphylactic reaction, also called anaphylaxis, is an immediate allergic reaction to a foreign substance (especially protein) that is introduced into the body. Previous exposure to the offending allergen is an important pre-requisite before anaphylactic reaction can occur. For example, a dog that is stung by a bee can sensitize the patient to the bee’s toxin as a result of the response of the immune system. The next time that the dog is stung, the immune system reacts by releasing substances that may trigger anaphylaxis. Mild cases of anaphylaxis usually result in extreme swelling at the site of the sting; while, in severe reactions, substances released by the cells of the immune system are distributed throughout the body, leading to systemic anaphylaxis. Mild reactions are more common than systemic anaphylaxis. It’s important to take note that these reactions are not normal because it is caused by the over-reaction of the body’s immune system to a foreign substance.
