A pannus, or panniculus, also called an abdominal apron, is a flap of excess skin, fat and tissue at the bottom of the abdomen. It occurs on overweight and morbidly obese patients as well as on people who have lost large amounts of weight but still have excess skin. Doctors can remove the surplus tissue with a surgical procedure called a panniculectomy. An excessively large pannus causes back strain.
