Hereditary Angioedema (HAE)
Hereditary angioedema is a rare genetic disorder characterised by recurrent episodes of severe swelling (angioedema).1 The most common areas of the body affected are the limbs, face, intestinal tract, and airway.1 Episodes may be caused by minor trauma or stress, but swelling often occurs without a known trigger.1 Swelling in the airway can restrict breathing and lead to life-threatening obstruction of the airway.1
