Thank you for your question. A tummy tuck will address excess skin & repair of the abdominal muscle. The abdominal wall can be weakened after pregnancy and (or) significant weight gain & loss. By repairing the muscle, not only does the appearance of your abdominal area improve, but your core strength as well. The repair of the muscle will cinch your waist like an inner corset, which will accentuate your curves. Liposuction will remove excess fat from unwanted areas with some skin retraction. Your expectations and health will dictate the best procedure(s) for you. I suggest a consultation with a board certified plastic surgeon to go over the options that best address your goals. Best of luck! Dhaval Patel MD Double Board Certified Plastic Surgeon Chicago South Barrington Oakbrook Orland Park
