What are the symptoms of hereditary angioedema?

The main symptom of HAE is swelling (angioedema). Swelling (angioedema) occurs or reoccurs in the hands, feet, gastrointestinal tract, genitals and throat that can develop over several hours and can last for two to five days. Painful swelling in hands and feet can decrease daily activities. When swelling (angioedema) involves the face or throat, seek immediate medical treatment. Swelling of the throat is dangerous due to blockage of the airways of the lungs and could be deadly. Swelling in the stomach can result in severe pain, vomiting, nausea, diarrhea and dehydration. These symptoms vary in frequency, severity and location from patient to patient.2

How is it diagnosed?

The diagnosis of hereditary angioedema is based upon patient history and physical findings during episodes of swelling (angioedema) combined with unexplained abdominal pain, family history and X-rays. Blood and genetic samples are also required to diagnose and distinguish between the two different types of hereditary angioedema, Type I and II.
