Diabetes Remission after weight loss surgery: is it
just weight loss?
Summary : Bariatric surgery results in weight loss of great magnitude and sustained overtime, with
remarkable improvement and/or remission of type 2 diabetes. The favorable change in the incretin gut
hormones after gastric bypass surgery (GBP) is thought to be responsible, in part, for diabetes remission
after GBP, independent of weight loss. After GBP, the post-prandial incretin hormones plasma
concentrations increase by 3-5 fold and the blunted incretin effect on insulin secretion improves rapidly
in patients with diabetes. In addition to changes in incretins, insulin secretion and glucose levels,
circulating branched chain amino acid, know to be associated with insulin resistance, decrease more
after GBP compared to diet. Bile acids and microbiota may also play a role in the improvement of glucose
metabolism after GBP. The relative role of weight loss and of bypass will be discussed. Understand the
mechanisms by which diabetes improves after GBP and may help develop less invasive treatment
options for obesity and diabetes.
