Angioedema is a type of swelling that occurs just beneath the skin or in the mucous membranes lining the mouth, throat, and airways. It is often accompanied by itching or hives. Angioedema can be triggered by a variety of factors, including allergies, medications, and certain underlying medical conditions.

Angioedema can range in severity from mild to severe. In mild cases, the swelling may be limited to the face or lips, and may resolve on its own within a few days. In more severe cases, the swelling may involve the throat or tongue, which can obstruct the airway and cause difficulty breathing. This can be a life-threatening emergency and requires immediate medical attention. Treatment for angioedema typically involves medications to reduce swelling and control any underlying triggers, such as antihistamines or corticosteroids. In some cases, epinephrine may be necessary to open the airway and restore normal breathing.
