Clinical Information

Angioedema is a rapid, localized skin swelling that often affects deeper layers of the skin and mucosa. The swelling is usually non-itchy but can be painful. Here are some essential points:

• Angioedema can occur due to an allergic reaction or non-allergic causes.
• It often affects areas with loose tissues, such as the face, throat, and limbs.
• The condition can be life-threatening if it causes airway obstruction.
• Treatments include avoiding triggers, antihistamines, and steroids.
• Genetic angioedema is a hereditary condition requiring different treatment approaches.

Synonyms Include:

• Allergic Angioedema
• Anaphylactic shock
• Non-allergic Angioedema
• Hereditary Angioedema
• Acute Angioedema
