2. Who is at Risk of Angioedema?

Risks of developing angioedema are higher in people who have experienced it before. Previous allergic reactions can also be a driving factor. Much more rarely, angioedema can be genetic, as a result of a condition called hereditary angioedema. Other environmental or physical factors that can cause angioedema or hives include sudden temperature changes and stress. Angioedema can also be a product of a previous injury.
