Metabolic syndrome (MS) is a conglomeration of risk factors associated with obesity and cardiovascular disease. Bariatric surgery is an effective treatment for obesity and its comorbidities. The aim of this study is to evaluate the remission rates of metabolic syndrome after bariatric surgery.


We retrospectively studied our bariatric population between 2005 and 2018. We analyzed patients who met the WHO Criteria for MS and determined the effects of bariatric surgery at 12 months on MS and its individual components. SPSS software was used to apply t-test for means.


Among the 1785 number of patients reviewed, 1491(83.5%) met WHO criteria for MS. Predominant procedure was LSG 62.9%(N=939), RYGB 22 %(N: 331), and gastric band(LAGB) conversions 14 %(N: 221). Mean BMI before surgery was 47±15.8 kg/m2. In post RNYGB patients, including conversions from LAGB, mean BMI preoperatively was 44.8±10kg/m2 versus postoperatively 31.5±5kg/m2 (P< 0.0001), preoperative glycemia 152.5±49mg/dL versus postoperative 102±23(P<0.0001), preoperative triglycerides 176±66 versus postoperative 102.7±33(P<0.0001), preoperative HDL 37.7±11 versus postoperative 57±12(P<0.0001) and MS remission rate at 12 months of 29%. In the post LSG patients, including conversions from LAGB, mean BMI preoperative was 48.2±17kg/m2 versus postoperative 32.1±14kg/m2(P< 0.0001), preoperative glycemia 149±45mg/dL versus postoperative 101±16mg/dL (P<0.0001), preoperative triglycerides 176±69mg/dL versus postoperative 105±37mg/dL(P<0.0001), preoperative HDL 38.8±12mg/dL versus postoperative 57±10mg/dL(


Bariatric Surgery is an effective method for reversing and controlling MS and its individual components. No difference in LSG and RYGB was noted.
