Angioedema is closely related to hives but largely affects the deeper layers of the skin. Many people who experience angioedema find it affects the face, especially around the mouth. Usually an allergic reaction, angioedema may also be a hereditary condition. It is not uncommon for people to have angioedema at the same time as hives. Though often harmless, angioedema can be life-threatening. Various treatments of angioedema exist.
While angioedema can be a hereditary condition, it may also be triggered by allergens. Allergies to insect bites or stings, contact with materials such as latex, medications, and food may trigger both angioedema and hives. In some cases, particularly among people with chronic urticaria (hives), the cause remains elusive. Allergists and dermatologists can help people treat angioedema.
