Hereditary angioedema, also known as HAE, is a rare genetic disorder that affects between 6,000 and 10,000 people in the United States. People who have HAE experience recurring episodes or attacks of severe swelling. These attacks most commonly affect the hands, feet, face, genitals, the gastrointestinal tract and the throat. There is no cure for HAE, but there are treatments available that can help people with HAE manage the condition. The following slides look at a few questions related to HAE attacks that you may want to discuss with your healthcare provider, including how attacks are treated, what can trigger an attack and when to seek emergency treatment.
