Is hereditary angioedema misdiagnosed?

ANSWER

A correct diagnosis of hereditary angioedema (HAE) is key. Sometimes people are treated for allergies when it's really HAE that causes their swelling. Antihistamines and corticosteroids that treat allergies don’t work well for this disease.

You can have severe stomach cramps. And if misdiagnosed, it can lead to surgery you don't need.

Your doctor will do a physical exam, and you'll need blood tests to confirm it’s HAE. Other members of your family may need to be tested, even if no one has symptoms.
