In brachyplasty, the excess of fat is subjected to liposuction and the loosened excess skin trimmed to get a satisfactory body contour. When there is drastic loss of weight either by dieting or bariatric surgery, the loss of subcutaneous fat results in skin becoming lax and hangs at dependant areas. Body contouring is a combination of liposuction and surgery to give improved appearance to certain parts of the body such as arms, thighs, abdomen and hips.
