What is the purpose of skin removal surgery?

The purpose of skin removal surgery is to remove loose or sagging skin after considerable weight loss. The most common type of skin removal surgery is called a body lift or body contouring, explains WebMD.

During body contouring, the surgeon removes excess skin in the abdominal region with a single cut along the abdomen. He also lifts and tightens other areas of the body as needed, including the arms, buttocks, thighs, hips and waist. The results usually are long-lasting if the person's weight remains consistent. However, some people have scarring and others have continued issues with sagging skin, says WebMD.
