Bile acids and bariatric surgery / 中华胃肠外科杂志

ABSTRACT

As an essential metabolic molecule, bile acids regulate triglyceride, cholesterol, energy metabolism. Bariatric surgery offers a treatment that can reduce weight and induce metabolic syndrome, but the mechanism is still unclear. New researches reveal that serum bile acids are elevated after surgery, as well as the improvement of metabolic disease. The surgery changes gastrointestinal tract, resulting in a short circuiting of the enterohepatic circulation of bile acids. Here we review the bile acids metabolism and their effect after bariatric surgery.
