Angioedema

Angioedema is a condition characterized by sudden, localized swelling that occurs beneath the skin's surface. It typically affects areas such as the face, lips, tongue, throat, and sometimes the hands and feet. Angioedema is caused by a buildup of fluid in deep layers of the skin and underlying tissues.

It can be classified into two types: allergic angioedema, which is often triggered by an allergic reaction, and non-allergic angioedema, which can be caused by various factors such as medications, infections, or genetic predisposition. The swelling in angioedema can be accompanied by itching, burning, or a tingling sensation. In some cases, it may be associated with other symptoms, such as hives or difficulty breathing.

Angioedema can range from mild to severe and, in rare cases, can be life-threatening if it affects the airways and causes swelling that obstructs breathing. Prompt medical attention is crucial, especially if there are signs of respiratory distress or a history of severe reactions. Treatment for angioedema may involve identifying and avoiding triggers, managing underlying conditions, and, in severe cases, the administration of medications to reduce swelling and alleviate symptoms.
