Symptoms can vary from person to person and attack to attack

The most common symptoms of hereditary angioedema (HAE) are repeated attacks of extreme swelling and pain. HAE attacks can be hard to predict and can begin without any warning signs. The severity and frequency of HAE symptoms can also be very different from person to person. Some people might have an HAE attack every 3 days, while others may have only 1 or 2 attacks per year.

Attacks can occur in many different parts of the body, including the skin, abdomen (trunk area) and throat.

  • Difficulty breathing
