Core Tip

Core Tip: Sleeve gastrectomy and distal small intestine bypass induced a reduction in body weight and significant improvements in glucose and lipid metabolism in the rats with streptozotocin-induced nonobese diabetes. The gut abundance of some Lactobacillus spp. increased in both the sleeve gastrectomy and distal small intestine bypass groups after surgery. The gut abundance of Lactobacillus was significantly correlated with the improvement in glycolipid metabolism and the change in serum fibroblast growth factor 21 levels.
