A flat and well-toned abdomen is something many of us strive for through exercise and weight control. Sometimes these methods cannot achieve our goals. Even individuals of otherwise normal body weight and proportion can develop an abdomen that protrudes or is loose or sagging. Also known as a abdominoplasty, a tummy tuck removes excess fat and skin, and is most cases restores weakened or separated muscles creating a abdominal profile that is smoother and firmer.
