Cosmetic plastic surgery removal of excess weight isn't a realistic technique for weight loss. This is simply because it isn't rational to place elective surgery patients through intensive surgical procedures that ultimately might fail. If people don't seem to be willing to adhere to a rigid weight loss program, then they'll not have long- term success once surgery has been performed. Though there are some studies that appear to demonstrate that enormous volume liposuction might cure diabetes, this is often controversial. The best way for patients to achieve long-term weight loss is with bariatric surgery.
