Diabetes reversal after bypass surgery linked to changes in gut microorganisms

Studies have shown that bariatric surgery can lead to remission of type 2 diabetes mellitus (T2DM) in rodents and humans, but this beneficial effect cannot be explained solely by weight loss. In a new study, researchers investigating gastric bypass in a mouse model of T2DM confirmed that bypass surgery improves glucose tolerance and insulin sensitivity. Interestingly, the improved metabolism occurred in conjunction with changes in gut microorganisms, suggesting a potential role for gut microbiota in diabetes remission.
