Hereditary Angioedema (HAE) is a very rare and potentially life-threatening genetic condition that occurs in about one in 10,000 to one in 50,000 people. HAE symptoms include episodes of edema (swelling) in various body parts including the hands, feet, face and airway.
In addition, patients often have bouts of excruciating abdominal pain, nausea and vomiting that is caused by swelling in the intestinal wall. Airway swelling is particularly dangerous and can lead to death by asphyxiation. For more detailed disease information on HAE, please visit www.haea.org
