Abdominoplasty, known more commonly as a tummy tuck, is a major surgical procedure to remove excess skin and fat from the middle and lower abdomen and to tighten the muscles of the abdominal wall. The procedure can dramatically reduce the appearance of a protruding abdomen. But bear in mind, it does produce a permanent scar, which, depending on the extent of the original problem and the surgery required to correct it, can extend from hip to hip. Your scars may actually appear to worsen during the first three to six months as they heal, but this is normal. Expect it to take nine months to a year before your scars flatten out and lighten in color. While they'll never disappear completely, abdominal scars will not show under most clothing, even under bathing suits. Complete abdominoplasty usually takes two to five hours, depending on the extent of work required. Partial abdominoplasty may take an hour or two.
