A tummy tuck, or abdominoplasty, is a cosmetic surgical procedure aimed at reshaping and firming the abdomen. The process involves removing excess skin and fat, as well as tightening the underlying abdominal muscles. This surgery is particularly beneficial for individuals who have loose skin or separated muscles that do not respond to diet or exercise. By addressing these issues, a tummy tuck helps create a smoother, more contoured abdominal profile.
