Abdominal wall surgery is a procedure that improves the appearance of flabby, stretched-out abdominal (belly) muscles and skin. It is also called a tummy tuck. It can range from a simple mini-tummy tuck to more extensive surgery. Abdominal wall surgery is not the same as liposuction, which is another way to remove fat. But, abdominal wall surgery is sometimes combined with liposuction. Your surgery will be done in an operating room in a hospital. You will receive general anesthesia. This will keep you asleep and pain-free during the procedure. The surgery takes 2 to 6 hours. You can expect to stay in the hospital for 1 to 3 days after surgery.
