Having a tummy tuck, also known as an abdominoplasty, will benefit women whose muscles have loosened during pregnancy. This procedure allows the muscles to be pulled back together and stitched into a new position making them tighter. The cost for a full tummy tuck is roughly £5,600. You may only need a moderate tummy tuck which costs less however the surgeon will advise what procedure will be best for you and give you the best result.
