A new study, according to WebMD, found that bariatric surgery was effective in patients with a body mass index (BMI) of less than 35. This means the weight-loss surgery could also benefit non-obese patients.

In addition to losing weight, patients with type 2 diabetes had their diabetes go into remission, according to WebMD.

Currently, the National Institute of Health recommends gastric bypass surgery only for patients whose BMI is over 35 for diabetes patients and for patients with a BMI of over 40 for those without diabetes or other obesity-related conditions.

According to WebMD, while the study supports the idea that weight-loss surgery can benefit the less obese, the study was done on a small sample of people. The study -- that was done by researcher John M. Morton, an associate professor of surgery and director of bariatric surgery at Stanford University – was done on a group of 15 people, including 12 who had diabetes.
