Abdominoplasty, also known as a tummy tuck, is designed to firm and smooth the abdomen. This cosmetic procedure removes excess skin and fat from the abdomen and may also tighten the muscles of the abdominal wall. Abdominoplasty is best suited for women and men who are in relatively good shape but have loose abdominal skin and/or a significant amount of abdominal fat that won’t respond to dieting or exercise.
