Abstract Objective: To investigate the impact of laparoscopic sleeve gastrectomy (SG) on plasma metabolites in obese patients with type 2 diabetes mellitus (T2DM) and identify key metabolites associated with weight loss. Subjects and methods: Nineteen obese T2DM patients who underwent SG surgery were selected as the study participants. Preoperative and postoperative plasma samples and clinical data were collected. High-performance liquid chromatography-mass spectrometry (LC-MS/MS) was used to detect plasma metabolites, and changes in the levels of metabolites before and after surgery […]
