Angioedema Overview

What Is Angioedema?

Angioedema is swelling that occurs beneath the surface of the skin. It commonly affects areas such as the face, lips, eyelids, and throat.

Common Symptoms

Symptoms may include:

  • Swelling of the lips, face, or eyelids
  • Swelling of the tongue or throat
  • Tightness or discomfort in affected areas
  • Episodes that may develop suddenly

How It Differs from Hives

Unlike hives, angioedema:

  • Affects deeper layers of the skin
  • May not be itchy
  • Often causes more noticeable swelling
  • Can occur with or without hives

Possible Causes

Angioedema may be triggered by:

  • Allergic reactions (foods, medications, insect stings)
  • Certain medications
  • Chronic hives
  • Unknown causes

When to Seek Medical Care

Immediate medical attention is needed if swelling:

  • Affects breathing
  • Involves the throat
  • Occurs rapidly and severely

Follow-up with a specialist is important after any serious episode.
