After gastric bypass surgery the body fat is sucked out leading to significant reduction in your weight, but the skin does not contract due to loss of elasticity. This leads to sagging skin. Body contouring surgery is performed to remove the excess skin. The body contouring procedure involves multiple procedures like tummy tuck, arm lift and thigh lift. The downtime for recovery depends on the extent of the surgery; usually it is between 1-2 months. The cost ranges somewhere between $20,000-$40,000 and there is no insurance coverage for this surgery.
