Long-term studies show that bariatric surgery results in significant long-term loss of weight, and can aid in recovery from diabetes, improvement in cardiovascular risk factors, and a reduction in mortality of 23% from 40%. The U.S. National Institutes of Health recommends bariatric surgery for obese people with a body mass index (BMI) of at least 40, and for people with BMI 35 and serious coexisting medical conditions such as diabetes. However, research is emerging that suggests bariatric surgery could be appropriate for those with a BMI of 35 to 40 with no comorbidities or a BMI of 30 to 35 with significant comorbidities.
