Obesity surgury can cure diabetes
The AP is reporting that in a new study gives the strongest evidence yet that obesity surgery can cure diabetes.
Patients who had surgery to reduce the size of their stomachs were five times more likely to see their diabetes disappear over the next two years than were patients who had standard diabetes care, according to Australian researchers.
The patients had stomach band surgery, a procedure more common in Australia than in the United States, where gastric bypass surgery, or stomach stapling, predominates.
Gastric bypass is even more effective against diabetes, achieving remission in a matter of days or a month, said Dr. David Cummings, who wrote an accompanying editorial in the journal but was not involved in the study.
Diabetes experts who read the study said surgery should be considered for some obese patients, but more research is needed to see how long results last and which patients benefit most. Surgery risks should be weighed against diabetes drug side effects and the long-term risks of diabetes itself, they said.
Experts generally agree that weight-loss surgery would never be appropriate for diabetics who are not obese, and current federal guidelines restrict the surgery to obese people.
The diabetes benefits of weight-loss surgery were known, but the Australian study in Wednesday's Journal of the American Medical Association is the first of its kind to compare diabetes in patients randomly assigned to surgery or standard care. Scientists consider randomized studies to yield the highest-quality evidence.
Obesity is a major risk factor for diabetes, and researchers are furiously pursuing reasons for the link as rates for both climb. What's known is that excess fat can cause the body's normal response to insulin to go haywire. Researchers are investigating insulin-regulating hormones released by fat and the role of fatty acids in the blood.
The death rate for stomach band surgery, which can cost $17,000 to $20,000, is about 1 in 1,000. There were only minor complications in the study. Stomach stapling has a 2 percent death rate and costs $20,000 to $30,000.
In the United States, surgeons perform more than 100,000 obesity surgeries each year.
The American Diabetes Association is interested in the findings. The group revises its recommendations each fall, taking new research into account.
