Patients who have loose abdominal skin and fat that is concentrated in the abdomen can benefit from tummy tuck surgery. Often, pregnancy or substantial weight loss may cause abdominal skin to become stretched out and excessive. A tummy tuck takes care of the belly pooch that does not go away even with diet and exercise. It tightens the abdominal muscles that have been separated and weakened in these cases. The procedure often eliminates stretch marks that are located below the naval, as the affected skin is removed as part of the operation.
