What sort of problem is anaphylaxis?

Allergic reaction: Anaphylaxis is a severe allergic reaction. Common symptoms are difficulty breathing, difficulty swallowing, a rash, skin redness, swelling, shortness of breath, coughing, and several others. It involves the entire body and needs to be treated right away as it can be life threatening.

Mortal allergy: Anaphylaxis is the most severe form of allergic reaction because it involves multiple organs. Death occurs perhaps in 0.1 to 1% of episodes because of laryngospasm (occlusion of the windpipe) or hypotension from leakage of plasma out of blood vessels. Other symptoms include asthma, hives, swelling of eyelids, lips, & tongue, nausea, vomiting & adbominal & uterine cramps. This is a 911 call.

Serious...: Anaphylaxis is a cascade of events that occurs due to a severe allergic reaction. In the worst cases, the throat swells to the point of obstructing a person's airway. This could be life-threatening. If this occurs, the person needs to get to the er stat so 911 should be called immediately.
