Duodenal-Jejunal Bypass Preferentially Elevates Serum Taurine-Conjugated Bile Acids and Alters Gut Microbiota in a Diabetic Rat Model

Background Bile acids (BAs) have emerged as important signaling molecules in regulating metabolism and are closely related to gut microbiota. Bariatric surgery elevates serum BAs and affects gut microbiota universally. However, the specific profiles of postsurgical BA components and gut microbiota are still controversial. The aim of this study is to investigate the serum profiles of BA components and gut microbiota after duodenal-jejunal bypass (DJB).
