The best candidates for a tummy tuck are men and women who would like to achieve smooth abdominal contours by removing excess stomach skin and fatty tissue and repairing any loose or separated abdominal muscles. The most common tummy tuck patients have undergone weight loss or pregnancy, resulting in saggy skin, stubborn fatty deposits and loose abdominal muscles. It’s also important to be in good overall physical and mental health, and to have realistic expectations about your results.
