Angioedema
Angioedema (pronounced: an-gee-oh-eh-dee-muh) is a medical condition characterized by swelling beneath the skin, often around the eyes and lips.
Etymology
The term "Angioedema" is derived from the Greek words "angeion" (meaning vessel) and "oídēma" (meaning swelling).
Definition
Angioedema is a condition that involves deep dermal, subcutaneous, and/or submucosal swelling. This is due to vascular leakage in the deeper layers of the skin and mucosa. The condition is often associated with hives, but the swelling is beneath the skin rather than on the surface.
Symptoms
Symptoms of angioedema can vary, but often include:
- Swelling of the skin, often around the eyes and lips
- Swelling of the hands, feet, and throat
- Abdominal cramping
- Difficulty breathing
Causes
Angioedema can be caused by an allergic reaction, a genetic mutation, or an unknown cause (idiopathic). It can also be a side effect of certain medications, such as ACE inhibitors.
Treatment
Treatment for angioedema depends on the cause. It may include avoiding triggers, such as certain foods or medications, and taking medications to reduce swelling and manage symptoms. In severe cases, emergency treatment may be needed to prevent airway obstruction.
