Angioedema

What is angioedema?

Angioedema is swelling under the skin. The swelling is similar to what you see with hives, but it occurs in the deeper layers of skin.

The swelling usually affects the eyes or lips but can show up anywhere in the body. Any swelling that blocks the airway is a medical emergency. You must call 911 or go to the nearest hospital emergency room immediately.

What causes angioedema?

Allergies are the most common cause of angioedema, but you can develop swelling from other conditions. Dr. Tano classifies angioedema into four types based on their causes:

Allergic angioedema

Allergic angioedema is the most common kind and is usually caused by food or environmental allergies.

Drug-induced angioedema

Certain medications, like penicillin, aspirin, and nonsteroidal anti-inflammatory drugs (NSAIDs), can trigger angioedema.

Hereditary angioedema (HAE)

HAE is the rarest cause of angioedema. It develops because the body doesn’t make enough of a blood protein called C1 esterase inhibitor, resulting in fluid leakage through the walls of the blood vessels.

Idiopathic angioedema

Idiopathic angioedema means the cause of the swelling isn’t known. However, there are possible triggers like stress, minor infections, or too much exercise. Highs and lows in body temperature might also cause this type of swelling. 

What are the symptoms of angioedema?

Sudden swelling is the primary symptom of angioedema. You might also have hives (welts) with the swelling. The swelling can affect one area, creating a line of swelling, or it can spread out. You could also feel pain or warmth in the area. 

If you have hives with your angioedema, they can be very itchy.

Older adults and people of Hispanic descent with angioedema are more likely to have severe symptoms.

What is angioedema treated?

How angioedema is treated will depend on how severe your symptoms are. Dr. Tano customizes your treatment plan to best meet your needs. If your symptoms are mild, you might not need treatment.

To manage symptoms, Dr. Tano could recommend:

• Antihistamines to reduce itching
• Immune-suppressing medication
• Intravenous (IV) C1 esterase inhibitor for HAE
• Corticosteroids

If you have angioedema symptoms, Dr. Tano can help you determine why and get you the right treatment.
