title: Metabolic Syndrome After Roux-en-Y Gastric Bypass Surgery in Chinese Obese Patients with Type 2 Diabetes.
abstract: Roux-en-Y gastric bypass (RYGB) surgery is currently the most effective treatment for substantial and sustained weight loss in morbidly obese individuals. We aim to determine the prevalence in Chinese obese patients with type 2 diabetes (T2DM) and the efficacy of surgical treatment of the metabolic syndrome (MetS) and its components with a control group in medical therapy.
  
  
  
  A total of 121 obese T2DM individuals who underwent RYGB and 93 nonoperative obese patients with T2DM were enrolled in the study. MetS was defined according to the criteria established by the Chinese Joint Committee for Developing Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults (JCDCG). We determined the change in MetS and the prevalence of its components and performed logistic regression models to evaluate predictors of MetS remission.
  
  
  
  One year after RYGB, all MetS components improved in the RYGB group and medication use decreased. Of the RYGB group, MetS prevalence decreased from 108 patients (83.3 %) to 20 (16.5 %), and from 88 patients (94.6 %) to 76 (81.7 %) in the control group. Multiple logistic regression analyses indicated that a shorter diabetes duration and higher percent excess weight loss (%EWL) were associated with a greater chance of MetS remission after surgery.
  
  
  
  RYGB induces considerable and persistent improvement in MetS prevalence in Chinese obese patients with T2DM. Diabetes duration and %EWL might act as potential prognostic markers in predicting the MetS reversibility.
