Abdominoplasty, also known as a tummy tuck, is a surgical procedure that removes excess skin and fat from the abdomen and tightens the muscles in the abdominal wall. It is typically performed by a plastic surgeon and is usually done on an outpatient basis. Abdominoplasty can be used to improve the appearance of the abdomen and is often done after significant weight loss or pregnancy. It can also help to alleviate any functional problems caused by excess skin and muscle laxity in the abdominal area.
