Tummy tuck primarily helps improve the look of the lower stomach region. Patients with excess skin after weight loss, pregnancy, and age can tighten the skin on the abdomen with a tummy tuck, resulting in a more flattering appearance. Sometimes, stubborn fat can linger in the abdominal region, and a tummy tuck can help address this. While a slimmer profile can be achieved with a tummy tuck, it is important to note that this procedure is not used to address weight loss.
