In its "Well" blog, the New York Times (11/28, O'Connor) reports that "weight loss surgery, which in recent years has been seen as an increasingly attractive option for treating type 2 diabetes, may not be as effective against the disease as it was initially thought to be, according to a new" study published in the journal Obesity Surgery. According to the article, "the study found that many obese type 2 diabetics who undergo gastric bypass surgery do not experience a remission of their disease, and of those that do, about a third redevelop diabetes within five years of their operation." The blog notes that "the findings contrast with the growing perception that surgery is essentially a cure for type 2 diabetes." The study monitored for a period lasting more than a decade thousands of diabetics who underwent gastric bypass surgery.
MedPage Today (11/29) reports that the study found that in "follow-up of 2,254 patients who showed complete remission of type 2 diabetes following bariatric surgery indicated that 35.1% (95% CI 32.0% to 38.4%) developed renewed symptoms within five years, according to David E. Arterburn, MD, MPH, of Group Health Research Institute in Seattle, and colleagues." The article adds that "moreover, the relapses did not appear to be closely related to subsequent regain of weight, the researchers reported." The researchers advised in their study, "Patients should be counseled that bariatric surgery alone does not reliably 'cure' diabetes."
