Angioedema Defined

Angioedema is swelling in the deep layers of the skin, often seen with urticaria (hives). Angioedema most often occurs in soft tissues such as the eyelids, mouth or genitals.

Angioedema is called "acute" if the condition lasts only a short time (minutes to days). This is commonly caused by an allergic reaction to medications or foods.

Chronic recurrent angioedema is when the condition returns over a long period of time. It most often does not have an identifiable cause.

Hereditary angiodema (HAE) is a rare, but serious genetic condition involving swelling in various body parts including the hands, feet, face, intestinal wall and airways.
