Abstract

Abstract:

Bariatric and metabolic surgery has been widely adopted both domestically and internationally for the treatment of obesity and its-related metabolic disorders, owing to its excellent efficacy in weight loss and metabolic disease remission. However, unlike other surgical procedures, bariatric and metabolic surgery, by removing a large portion of the stomach tissue and/or bypassing part of the small intestine, increases the risk of malnutrition. Malnutrition is a common clinical problem after bariatric and metabolic surgery, thus it is crucial to prevent complications related to malnutrition while achieving effective weight loss and alleviating metabolic diseases. This article reviews the mechanism, incidence, and postoperative management of malnutrition after bariatric and metabolic surgery, with the aim of providing reference for clinical work.

Key words: Obesity, Metabolic Disease, Bariatric and Metabolic Surgery, Malnutrition, Management
