Encouraging Health

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.

Most of the surgery patients were able to stop taking diabetes drugs and achieve normal blood tests.

“It’s the best therapy for diabetes that we have today, and it’s very low risk,” said the study’s lead author, Dr. John Dixon of Monash University Medical School in Melbourne, Australia.

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.

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.

In the Australian study, all the patients were obese and had been diagnosed with type 2 diabetes during the past two years. Their average age was 47. Half the patients underwent a type of surgery called laparoscopic gastric banding, where an adjustable silicone cuff is installed around the upper stomach, limiting how much a person can eat.

Both groups lost weight over two years; the surgery patients lost 46 pounds on average, while the standard-care patients lost an average of 3 pounds.

Blood tests showed diabetes remission in 22 of the 29 surgery patients after two years. In the standard-care group, only four of the 26 patients achieved that goal. The patients who lost the most weight were the most likely to eliminate their diabetes.

Both patient groups learned about low-fat, high-fiber diets and were encouraged to exercise. Both groups could meet with a health professional every six weeks for two years.

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.

Diabetes in men can affect testosterone, too.
