You can look forward to a smaller waistline and leaner looking stomach after a tummy tuck, but it is important to understand that a tummy tuck is not a weight loss surgery. People who have lost a significant amount of weight may reward themselves with tummy tuck surgery to remove loose skin and pockets of excess fat. A tummy tuck can be a powerful way to complete your weight loss journey, but you should be at a healthy and stable weight before surgery.
