A flat abdomen can be an attractive asset, but there are many factors in life that can impact the midsection of the body. Weight fluctuations, pregnancy, aging, medical procedures and even genetics can all create looser skin, excess fat and a bulge around the middle. Abdominoplasty or the “tummy tuck” is a cosmetic surgical procedure that can remove excess fat and skin, while restoring the tightness of the abdomen wall muscles.
