The purpose of a tummy tuck is to eliminate excess skin and fat and to restore weak muscles, according to the American Society of Plastic Surgeons. Called abdominoplasty, the procedure gives a patient a firmer and flatter abdomen but does not compensate for lack of proper diet and regular exercise.
Candidates for tummy tucks include healthy women who have had multiple pregnancies that resulted in sagging skin and stretched abdominal muscles, according to WebMD. The procedure can benefit healthy people who have lost significant amounts of weight that resulted in sagging abdominal skin. A tummy tuck is a major surgical procedure that can take up to five hours under general anesthesia. Patients may experience soreness for weeks or months after the procedure, which leaves permanent scars.
