Weight loss surgeries can result in long-lasting weight loss and enhanced outcomes for people with type 2 diabetes, but the degree of improvement varies depending on the procedure.
Researchers in a study analysed data from 27 patients, 18 of which had type 2 diabetes with half undergoing a sleeve gastrectomy and the other half a duodenal switch procedure. One month prior to surgery and 72 hours post-surgery, blood samples were collected to compare before and after values for markers including blood sugar, insulin levels, the appetite hormone ghrelin, and gut hormones, such as GLP-1.
3 days after surgery, those who got the duodenal switch operation had much lower fasting blood sugar levels as well as lower postprandial glucose excursions (PPGEs). Majority of the patients had diabetes cured in just 48 hours.
According to the researchers, the improvement of diabetes outcomes seen after the duodenal surgery can be primarily attributed to hormonal changes. This study suggests that such changes, which depend in part upon the length of intestine bypass, are more favourable with the duodenal surgery rather than the sleeve gastrectomy.
