Which condition is characterized by airway obstruction due to swelling, often after an insect sting?

The condition characterized by airway obstruction due to swelling, often after an insect sting, is angioedema. This condition involves the rapid swelling of the deep layers of the skin and submucosa, commonly affecting areas like the face, throat, and airways. When angioedema occurs in the throat, it can lead to significant airway obstruction, making it a critical medical emergency.

One notable aspect of angioedema is its potential connection to allergic reactions, including those triggered by insect stings. In such instances, the swelling can occur quickly and may necessitate immediate intervention to secure the airway and manage the swelling.

While anaphylaxis also involves severe allergic reactions and can lead to airway obstruction, angioedema specifically refers to the type of swelling itself. Anaphylaxis encompasses a broader set of symptoms, including cardiovascular instability and respiratory distress, alongside angioedema. Differentiating between the two is important for medical treatment and management.

Urticaria, commonly known as hives, primarily affects the superficial layers of the skin and usually presents as itchy welts, rather than swelling that would obstruct the airway. Asthma, on the other hand, is a chronic respiratory condition characterized by bronchoconstriction, inflammation
