Hereditary Angioedema (HAE) Defined

Hereditary Angioedema (HAE) is a rare genetic condition. The term “edema” means swelling. Symptoms of HAE can include painful episodes of swelling, typically in the face, hands, feet or genitals. Dangerous swelling can also occur in the airways of the lungs or the intestinal walls.

HAE is an inherited condition. Both HAE and allergic angioedema can cause swelling, but allergic angioedema is skin reaction commonly associated with urticara (hives).
