Anaphylaxis

Anaphylaxis is a severe and rapid systemic allergic reaction to a trigger substance, called an allergen. Minute amounts of trigger substances may cause a life-threatening anaphylactic reaction. Anaphylaxis may occur after ingestion, inhalation, skin contact or injection of a trigger substance. The most severe type of anaphylaxis - anaphylactic shock - will usually result in death if untreated.
