Angioedema
Angioedema is a swelling of the deeper layers of the skin. It happens most often on the hands, feet, and face. If the angioedema occurs in the throat, normal breathing or swallowing can be blocked and emergency measures must be taken. Fortunately, angioedema rarely happens in the throat. Angioedema can also cause swelling of the lips or eyes and has no long-lasting effects. It usually lasts one or two days and often occurs in conjunction with hives.
Hereditary angioedema is a rare inherited form that differs from other types of angioedema. It is not triggered by an allergic reaction and involves deep tissue swelling and is never associated with hives. Swelling in the gastrointestinal tract can led to severe pain in the abdomen and can be mistaken for appendicitis. Hereditary angioedema can be detected through blood tests and can be effectively treated with special hormone medications.
