A tummy tuck (abdominoplasty) is an excellent way to remove this excess fat and skin from the middle and lower abdomen (or tummy) region when diet and exercise yield insufficient results. A tummy tuck contours the abdominal area, making the stomach flatter and the waist slimmer. The muscles can be tightened and brought closer to the middle of your belly making them more efficient and flatter while reversing some separation that may have been caused by pregnancy or previous weight gain.
