Abstract:

Metabolic and bariatric surgery (MBS) is an internationally recognized effective and sustained treatment for obesity. More and more studies have confirmed that patients with obesity already have a certain extent of nutritional deficiency before surgery. Due to the changes in the anatomy and function of digestive tract after surgery, patients can lose weight steadily and continuously, while the preoperative nutritional deficiency will also be aggravated, and a series of nutrition-related complications will occur. This article elaborates the mechanism of nutritional deficiency and the treatment of nutritional complications in patients before and after MBS. Combined with clinical experience, it summarizes perioperative nutritional management, so as to provide reference for clinical medical staff to improve the nutritional status of bariatric surgery patients.

Key words: Metabolic and bariatric surgery, Nutrition, Mechanism, Prevention, Treatment, Perioperation
