Weight loss surgery may be a more effective treatment strategy for obese people with type 2 diabetes than lifestyle interventions alone, says a new study.
The study was conducted by researchers at the University of Pittsburgh's Medical Center on 61 obese adults with type 2 diabetes between the age group of 25 and 55 years. Some underwent weight loss surgical procedure while others were given intensive weight loss intervention for one year followed by a low-level lifestyle intervention for 2 years. The duration of the study was for three years.
After three years, the results of the study revealed that 40 percent of the participants who received gastric bypass procedure and 29 percent of the participants who received a laparoscopic gastric band procedure reported either partial or complete remission of their type 2 diabetes.
Complete remission of type 2 diabetes was achieved in 15% of gastric bypass patients and 5% of laparoscopic gastric banding patients.
No one was reported getting rid of type 2 diabetes in the non-surgical group who received intensive lifestyle interventions.
The researchers noted that blood sugar control improved more in the participants who received surgical procedure, compared to the lifestyle intervention group. The surgery groups were also more likely to no longer need medication for diabetes management.
Lead author Dr Anita Courcoulas, University of Pittsburgh Medical Center, said, "I do think it adds strongly to the growing body of data that surgery should be considered to treat people with obesity and diabetes."
The study was published online in JAMA Surgery.
