ABSTRACT
Objective:To explore the association of weight loss with diabetes remission after metabolic surgery in patients with type 2 diabetes mellitus(T2DM) for 10 years and more.Methods:Data of T2DM patients with obesity who underwent metabolic surgery in the General Surgery Department & Obesity and Metabolic Disease Center of China-Japan Friendship Hospital from November 2017 to June 2021 were retrospectively collected and analyzed. Remission of diabetes was defined as glycated hemoglobin (HbA1c) < 6.5% or fasting blood glucose < 7.0 mmol/L after discontinuing anti-diabetic medication for more than 3 months. The patients were followed up and divided into two groups according to whether the percentage total weight loss (%TWL) was ≥ 20% or not. The age, sex, body mass index (BMI), fasting C-peptide, and HBA1c were compared between the two groups.Results:Among 65 (28 males and 37 females) patients with T2DM for ≥ 10 years , 50 (76.9%) achieved diabetes remission after a median of 12-month follow-up. 6.2%, 41.5% , 38.5% and 13.8% of the patients achieved %TWL < 10%, 10~20%, 20~30% and ≥ 30% , respectively. The diabetes remission rates were 50%, 63.0%, 92.0% and 88.9%, respectively. Compared with the %TWL < 20% group, the preoperative weight [(95.5±18.8) kg vs (85.5±11.0) kg, P = 0.012] and BMI [(34.4±6.0) vs (30.9±3.3) , P = 0.006] were significantly higher in the %TWL ≥ 20% group, and diabetes remission rates was aslo significantly higher in the %TWL ≥ 20% group (91.2% vs 61.3%, P = 0.010) . After adjusting for age, preoperative BMI, fasting C-peptide and duration of T2DM, Cox multivariate regression analysis showed that %TWL ≥ 20% was independently associated with diabetic remission after metabolic surgery in patients with T2DM for ≥ 10 years (HR = 1.99, 95% CI: 1.03 to 3.83, P = 0.04). Conclusions:More than 70% of patients with T2DM for ≥ 10 years could achieve diabetes remission after metabolic surgery. %TWL ≥ 20% may be one independent factor of diabetes remission in patients with long-duration T2DM.
ABSTRACT
La diabetes es una enfermedad croÌnica que aparece cuando el paÌncreas no produce insulina suficiente o cuando el organismo no utiliza eficazmente la insulina que produce. La insulina es una hormona que regula el azuÌcar en la sangre. El efecto de la diabetes no controlada es la hiperglucemia (aumento del azuÌcar en la sangre), que con el tiempo danÌa gravemente muchos oÌrganos y sistemas, especialmente los nervios y los vasos sanguiÌneos.
Diabetes is a chronic disease that appears when the pancreas does not produce enough insulin or when the body does not use the insulin it produces effectively. Insulin is a hormone that regulates blood sugar. The effect of uncontrolled diabetes is hyperglycemia (increased blood sugar), which over time severely damages many organs and systems, especially nerves and blood vessels.
ABSTRACT
OBJECTIVES: Several predictors of type 2 diabetes mellitus (T2DM) remission after metabolic surgery have been proposed and used to develop predictive scores. These scores may not be reproducible in diverse geographic regions with different baseline characteristics. This study aimed to identify predictive factors associated with T2DM remission after Roux-en-Y gastric bypass (RYGB) in patients with severe obesity. We hypothesized that the body composition alterations induced by bariatric surgery could also contribute to diabetes remission. METHODS: We retrospectively evaluated 100 patients with severe obesity and T2DM who underwent RYGB between 2014 and 2016 for preoperative factors (age, diabetes duration, insulin use, HbA1c, C-peptide plasma level, and basal insulinemia) to identify predictors of T2DM remission (glycemia<126 mg/dL and/or HbA1c<6.5%) at 3 years postoperatively. The potential preoperative predictors were prospectively applied to 20 other patients with obesity and T2DM who underwent RYGB for validation. In addition, 81 patients with severe obesity (33 with T2DM) underwent body composition evaluations by bioelectrical impedance analysis (InBody 770®) 1 year after RYGB for comparison of body composition changes between patients with and those without T2DM. RESULTS: The retrospective analysis identified only a C-peptide level >3 ng/dL as a positive predictor of 3-year postoperative diabetes remission, which was validated in the prospective phase. There was a significant difference in the postoperative body composition changes between non-diabetic and diabetic patients only in trunk mass. CONCLUSION: Preoperative C-peptide levels can be useful for predicting T2DM remission after RYGB. Trunk mass is the most important difference in postoperative body composition changes between non-diabetic and diabetic patients.

Recently, the number of obesity and diabetes mellitus have increased rapidly not only in Korea but also around the world. It is even called the new pandemic of the 21st century. In Korea, the diabetes growth rate, which exceeds the obesity growth rate, is a bigger problem. Accordingly, the simultaneous treatment of diabetes and obesity has become a global issue. In this article, we will review various obesity treatments to help diabetes remission and take a look at meaningful previous study about dietary methods for obesity. This overview includes the update of medications for obesity and the practical method for clinicians in field of obesity treatment in Korea.
