In a study published in the March 2009 issue of The American Journal of Medicine, investigators analyzed 621 studies from 1990 to April of 2006, which showed that 78.1% of diabetic patients had complete resolution and diabetes was improved or resolved in 86.6% of patients as the result of bariatric surgery.
It is now fully established that obesity is the most important reason for type 2 diabetes. Weight loss is the only way to control this chronic disorder. For individuals who have been unable to achieve significant weight loss through diet modifications and exercise programs alone, bariatric surgery may help to attain a more healthy body weight.
Bariatric surgery also known as weight-loss surgery refers to the various surgical procedures performed to treat obesity by modification of gastro-intestinal tract to reduce nutrient intake and/or absorption. Among the number of surgical options available to treat obesity the most popular ones are laproscopic adjustable gastric binding, gastroplasty, gastric bypass and biliopancreatic diversion/duodenal switch (BPD/DS).
Researchers observed a progressive relationship of diabetes resolution and weight loss as a function of the operation performed. Gastric banding yielded 56.7% resolution, gastroplasty 79.7%, gastric bypass 80.3% and BPD/DS 95.1%. After more than 2 year post-operative, the corresponding resolutions were 58.3%, 77.5%, 70.9%, and 95.9%. In addition, the percent excess weight loss was 46.2%, 55.5%, 59.7% and 63.6%, for the type of surgery performed, respectively.
Considering the potential benefits of millions of people, randomized clinical trials to compare surgery and medical therapies for type 2 diabetes is urgently required.
