According to a study from the Institution of Internal Medicine in Finland, bariatric surgery has helped to significantly increase the remission rate for type 2 diabetes in both short term and long term obese patients. It also contributed to preventing any complications of diabetes.
About the Study
At just two years, nearly 72% of patients who had bariatric surgery were in remission compared with 16.4% of controls. The number of patients still in remission 15 years after surgery fell to 31% however this figure is higher than ever seen before. Ultimately, bariatric surgery typically results in a remission rate of up to 90% of patients in the first two years after surgery. However, many studies have assessed various outcomes and there has been nothing found about why some patients have long-lasting remission and why others do not.
A larger study of nearly 2,010 obese patients who had bariatric surgery was done with 2,037 controls who received typical care. This study was held jointly by both the American Society for Metabolic and Bariatric Surgery and The Obesity Society.
The current analysis for this study includes nearly 345 patients and 262 controls that had type 2 diabetes. 68.1% of the patients had vertical banded gastroplasty, 18.7% gastric banding and 13.2% gastric bypass surgery. Both the control and surgery groups were the same, although the control group had a slightly higher age average and the surgery group of patients had a slightly higher average body mass index.
The duration of diabetes diagnoses was both 3 and 3.5 years in both the surgery and control groups and fasting glucose levels were about 156 mg/dL for both groups. While the control group didn’t lose a lot of weights, the largest and most sustained weight loss occurred in the surgery group.
Nearly two years post-surgery, more than 90% of those who had diabetes for less than a year before surgery were in a remission state. Ultimately, remission rates at two years for those with diabetes for more than three years were low. This means the sooner bariatric surgery is had after a diagnosis, the better the chance for remission after weight-loss surgery.
Researchers also found that bariatric surgery can prevent complications, and they concluded that there was a 47% reduction in stroke and myocardial infarction. To show the effects of bariatric surgery, researchers double-checked the obesity database. They found that in the last 20 years, there was a 47% reduction in microvascular complications and nearly 34% less macrovascular complications.
Ultimately, those with a disease for less than a year, there was a 53% reduction in complications from their diabetes and a .74 hazard ratio.
