No, tummy tuck is not a weight loss surgery and should not significantly affect your weight. Although Dr. Green can remove a small amount of fat when performing tummy tuck, this surgery is primarily focused on removing loose skin that makes your midsection appear wider than it is. Tummy tuck is best for patients who are near their goal weight and have maintained a steady weight for several months. If your main concern is losing weight, diet and exercise remain your best options.
