The first year after surgery can be a “honeymoon” with new food choices, new habits, and improved self-esteem but many patients soon start regaining weight. Dr. John Morton, past president of the American Society for Metabolic and Bariatric Surgery (ASMBS) and head of bariatric surgery at Stanford University School of Medicine, California, indicates that obese patients who regain some weight can still see health benefits from the surgery .
Peter T. Hallowell, MD, of the University of Virginia, Department of Surgery, Charlottesville, Virginia, and colleagues studied bariatric surgery in 401 patients and reported a clear survival advantage in morbidly obese patients who pursued gastric bypass surgery over those not undergoing the procedure .
