Definition

In-Depth
What You Need to Know
Angioedema results from fluid leaking into deeper layers of the skin and subcutaneous tissue, producing soft, non-pitting swelling that is often asymmetric and can be disfiguring but is typically not itchy, distinguishing it from the superficial welts of hives. The condition can be allergic (triggered by foods, medications, or insect stings), non-allergic (often caused by ACE inhibitor medications), hereditary (due to C1-esterase inhibitor deficiency), or idiopathic. When angioedema involves the tongue, throat, or larynx, it can become a life-threatening emergency due to potential airway obstruction, requiring immediate administration of epinephrine and emergency medical care. Allergists play a critical role in determining the underlying cause through detailed history, blood tests including complement levels and C1-esterase inhibitor function, and allergy testing when appropriate. Treatment depends on the type of angioedema and may include antihistamines, corticosteroids, epinephrine for acute episodes, and for hereditary angioedema, specialized medications such as C1-esterase inhibitor concentrate, icatibant, or lanadelumab.
