The goal of surgery after weight loss is to remove excess skin and fat and improve body contours. After significant weight loss, it is quite common to have large amounts of inelastic skin with or without large fatty deposits that cause distortion of the normal body shape. Virtually any area of the body can be affected. There are several surgical procedures that fall under this heading to address the various regions of the body. Often these procedures are more extensive than similar surgeries in the non-massive weight loss patient, therefore staged procedures are usually necessary to address all areas of concern.
