Nutritional status of type 2 diabetic patients after gastric bypass and its influencing factors
Objective To investigate the nutritional status of patients with type 2 diabetes after gastric bypass and its influencing factors.Methods The clinical data of 129 patients with type 2 diabetes who underwent gastric bypass in Shanghai Sixth People's Hospital from May 2018 to April 2021 were retrospectively analyzed.The nutritional status of the patients was evaluated by the control the nutritional status(CONUT)scoring 3 months after surgery.According to the nutritional status,they were divided into malnutrition group and normal nutrition group.Multivariate logistic regression analysis was used to assess the influencing factors of malnutrition 3 months after gastric bypass in patients with type 2 diabetes mellitus.Results Three months after gastric bypass,36 patients(27.91%)were cured,68 patients(52.71%)were relieved,and 25 patients(19.38%)were ineffective,with a total effective rate of 80.62%.Of the 129 patients,68(52.71%)had normal nutrition and 61(47.29%)had malnutrition,including 45 cases(73.77%)of mild malnutrition,13 cases(21.31%)of moderate malnutrition,and 3 cases(4.92%)of severe malnutrition.The age and course of disease in the malnutrition group were higher than those in the normal nutrition group(P＜0.05),while the circumference of the upper arm,triceps skinfold thickness,preoperative hemoglobin(Hb),glycosylated hemoglobin and triacylglycerol(TG)levels in the malnutrition group were lower than those in the normal nutrition group(P＜0.05).Multivariate logistic regression analysis showed that age,course of disease,preoperative Hb and TG were influencing factors of malnutrition in type 2 diabetic patients 3 months after gastric bypass(P＜0.05).Conclusion Gastric bypass is effective in patients with type 2 diabetes,but postoperative nutritional status still needs to be improved.Age,course of disease,preoperative Hb and TG levels will affect the nutritional status of patients with type 2 diabetes after gastric bypass.
