　　【Summary】 The incidence of obesity and obesity-related diseases (such as T2DM) increases year by year in the world. Metabolic surgery has increasingly been applied to patients with severe obesity. Studies have indicated that metabolic surgery is effective in obesity and obesity-related diseases. Since patients undergoing metabolic surgery are obese or severely obese，whose physiological and pathological changes are different with those of non-obese patients，a comprehensive assessment and management during perioperative period and after the operation were needed. This article mainly expounds preoperative evaluation and preparation，management of surgery process and postoperative nutrition and endocrine management.
