Proper diet and exercise does not always result in a flat stomach. Loose skin, excess fat and lax abdominal muscle can sometimes limit your abdominal appearance.
If you are bothered by the appearance of your stomach, a tummy tuck (Abdominoplasty) may be a good solution
A tummy tuck surgically removes redundant skin and unwanted fat from the abdominal area and may also tighten the muscles of the abdominal wall. The result is a sleeker profile and a tighter, flatter stomach.
