Effects of oral nutritional supplementation in a case-management model on body composition changes in patients after bariatric surgery.

This study explores the effects of oral nutritional supplementa-tion in a case-management model on body composition alterations in patients after bariatric surgery. One hundred and twenty obese patients admitted to the Jiangsu Province Suqian Hospital from January 2024 to March 2025 who underwent bariatric surgery were included. Patients were divided into an obser-vation group and a control group. The control group adopted routine nursing measures. Based on routine nursing measures, the observation group adopted an individualized nutritional supplement intervention according to the ideal body weight and the principle of limiting energy intake. One and three months after surgery, compared with the control group, the improvements of body fat percentage, free fat mass (FFM), body mass index (BMI), body weight, skeletal muscle mass, and excess weight loss rate in the observation group were more significant. The albumin, hemoglobin, and total protein levels were higher; emotional eating, external eating, restrained eating, and the Bariatric Surgery Self-management Questionnaire (BSSQ) scores were significantly improved. The scores of physical function, social function, physical pain, emotional func-tion, general health, mental health, physical role, and vitality were higher. The total incidence of postoperative complications was lower, while the total nurs-ing satisfaction rate of patients was higher. To sum up, oral nutritional sup-plementation in the case-management model can improve body composition, promote nutritional status, reduce the incidence of complications, promote postoperative self-management ability, and enhance the quality of life and nurs-ing satisfaction in patients after bariatric surgery.
