What is Angioedema?

An allergic reaction causing sudden swelling in the deep layers of the skin or mucous membranes

Swelling occurs in the lips, eyelids, tongue, and throat, with histamine release being the primary cause. It may appear alongside hives.

Caution

Seek emergency medical attention immediately if throat swelling causes difficulty breathing.

Main causes & characteristics of Angioedema

This reaction is known to involve a sudden increase in vascular permeability in the deep dermis, subcutaneous tissue, or mucous membranes, resulting in localized swelling. Histamine release triggered by allergies to foods, medications, or insect stings is commonly cited; non-allergic types — including hereditary and drug-related forms — are also known to exist. It frequently occurs alongside urticaria (hives).

Managing Angioedema

If swelling involves not just the lips and eyelids but also the tongue or throat, causing difficulty breathing, this may constitute an emergency and seeking immediate medical attention is strongly recommended. Recording and avoiding foods or medications suspected as triggers is advisable. When episodes recur, consulting a dermatologist or allergist to identify precipitating factors is recommended.

Related information

Urticaria (hives), histamine, allergic reactions, anaphylaxis, and hereditary angioedema are commonly discussed alongside this condition. Unlike superficial urticaria, angioedema is distinguished by its involvement of deeper skin layers.

Everyday care tips

When starting new foods, medications, or cosmetics, testing a small amount first and keeping a written record of past triggers that caused swelling may help.
