Any type of surgery that permanently changes the size of the stomach, bypasses part of the small intestine, or both, is called bariatric surgery. This is not the same as liposuction, a procedure that involves the suctioning of fat from certain parts of the body for cosmetic surgery.
Liposuction may alter a person's shape, but it does not improve overall health. Weight loss operations, on the other hand, can provide a major benefit to both life and death, such as a diabetes type 2 treatment, for the right person.
