Weight Loss Surgery May Not Combat Diabetes Long-Term.
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 report. 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.
“Some people are under the impression that you have surgery and you’re cured,” said Dr. Vivian Fonseca, the president for medicine and science for the American Diabetes Association, who was not involved in the study. “There have been a lot of claims about how wonderful surgery is for diabetes, and I think this offers a more realistic picture.”
The findings suggest that weight loss surgery may be most effective for treating diabetes in those whose disease is not very advanced. “What we’re learning is that not all diabetic patients do as well as others,” said Dr. David E. Arterburn, the lead author of the study and an associate investigator at the Group Health Research Institute in Seattle. “Those who are early in diabetes seem to do the best, which makes a case for potentially earlier intervention.”
After surgery, about 68 percent of patients experienced a complete remission of their diabetes. But within five years, 35 percent of those patients had it return. Taken together, that means that most of the subjects in the study, about 56 percent — a figure that includes those whose disease never remitted — had no long-lasting remission of diabetes after surgery.
