What is it?

Angioedema is swelling of the deep layers of the skin, typically around the face and lips. Acute angioedema is a pretty common presentation that usually resolves on its own. The cause for angioedema is often not found. It may be caused due to exposure to foods (peanuts, shellfish,fish, milk, soy), medications, allergens such as pollen and insect bites. Angioedema may become life-threatening if the tongue or the throat get swollen and block the airway.

Signs & symptoms

Angioedema symptoms may include welts, swelling, especially around the eyes, cheeks or lips, pain and warmth in the affected areas.


Diagnosis is based upon findings from medical history and physical examination. Further evaluation may include blood tests and allergy skin tests.


Sometimes, angioedema does not require any treatment and may resolve on its own. If there is discomfort for the patient, treatment such as antihistamines may help. For severe angioedema, oral corticosteroid may be given. If the trigger is known, it's best to avoid it the next time.
