Body lifts are surgical procedures that tighten skin that has loosened after weight loss or normal aging. These include inner thigh lifts, lower body lifts (tummy tuck extending to the back to tighten loose buttock and lateral thigh skin) and brachioplasty (arm skin tightening). The length of the surgery and where it is done depends on how many locations are tightened. Insurance will occasionally contribute to the cost if the operation is done to correct massive weight loss such as after stomach stapling or bypass for morbid obesity.
