Dr. Loren Wissner Greene, an endocrinologist at NYU Langone Medical Center in New York City, expressed little surprise at the findings.
"That's been widely reported," she noted. "Of course, how one fares does depend on the individual. One can eat around any procedure, meaning that if a patient drinks high-caloric liquids following surgery, and manages not to lose weight, that can affect the result," Greene explained.
"At the same time, there is very good evidence for diabetic remission after surgery, particularly for diverting procedures, where there could be a beneficial impact on gut hormones like leptin and ghrelin," Greene added.
"There are some risks, however," she cautioned. "And people who have bad presurgical problems -- those with high blood pressure or obesity-related sleep apnea -- might be limited in terms of the type of obesity surgery they can get. But for those who can do it, it may really be the better way to go. And in the end, though surgery is extremely expensive, it might even be cheaper than having to take expensive diabetic medications for years to come."
