Bariatric surgery is the technical term for operations that are designed to help people lose weight where diet and exercise alone have failed. Surgical therapy has been shown to be effective over both the short-term and long-term in achieving weight loss. However, surgery should be considered as part of an overall plan of weight management - it is not an option for all people who are overweight, and surgery alone without dietary or lifestyle modifications may not be successful.
