Angioedema

Angioedema is a condition characterized by sudden swelling beneath the skin, often affecting the face, lips, throat, and sometimes the hands and feet. It typically occurs as an allergic reaction, where the body responds to allergens—like certain foods, medications, or insect stings—by releasing chemicals that cause blood vessels to leak fluid. This swelling can be uncomfortable and, in severe cases, may obstruct breathing, requiring prompt medical attention. While it can happen on its own, it may also accompany hives or other allergic symptoms. Management often includes avoiding triggers and using antihistamines or other medications.
