Which term describes swelling caused by an allergic reaction to bee stings or ACE inhibitors?

The term that describes swelling caused by an allergic reaction to bee stings or ACE inhibitors is angioedema. This condition specifically involves the rapid swelling of the deeper layers of the skin and mucous membranes, often affecting the face, lips, throat, and sometimes the gastrointestinal tract. The swelling occurs as a result of the release of histamines and other chemicals in response to an allergen, leading to increased permeability of blood vessels.

Angioedema can manifest on its own, but it can also be associated with other allergic reactions. In the case of bee stings, the venom acts as an allergen, prompting the immune system to respond. Similarly, certain medications, including ACE inhibitors, can induce a hypersensitive reaction in some individuals, resulting in angioedema.

While dermatitis represents inflammation of the skin often due to irritants or allergens, it is a surface-level condition and not primarily characterized by the deeper swelling seen in angioedema. An asthmatic reaction primarily involves bronchospasm and respiratory distress rather than localized swelling. Anaphylaxis is a severe, systemic allergic reaction that includes multiple symptoms, such as difficulty breathing and a drop in blood pressure, but angioedema can be a symptom of anaphyl
