Introduction to anaphylaxis
Anaphylaxis refers to a rapidly developing and serious allergic reaction that affects a number of different body systems at one time. Severe anaphylactic reactions can be fatal. Although many patients experience minor allergy symptoms, a small number of people are susceptible to a severe reaction that can lead to shock or even death.
Anaphylaxis is often triggered by substances that are injected or ingested and thereby gain access into the bloodstream. An explosive reaction involving the skin, lungs, nose, throat, and gastrointestinal tract can then result. Although severe cases of anaphylaxis can occur within seconds or minutes of exposure and be fatal if untreated, many reactions are milder and can be ended with prompt medical therapy.
