Abstract: Background: the increased prevalence of overweight and obesity has reached alarming proportions worldwide and has serious health implications, including an association with an increase in metabolic syndrome. Among the methods to control metabolic syndrome, bariatric surgery plays an important role and can provide a significant improvement in the components of metabolic syndrome.Objective: the aim of this study was to determine the relationship between the preoperative body mass index (BMI) and the postoperative resolution of metabolic syndrome [using the National Cholesterol Education Program (NCEP ATP III criteria)] in patients undergoing Roux-en-Y gastric bypass (RYGB).Methods: Retrospective analysis of a consecutive series of cases, stratified by BMI into three groups (group 1, BMI < 40 kg/m(2), group 2, BMI 40-49.9 kg/m(2), and group 3, BMI 50 >= kg/m(2)) consisting of both sexes between 20 and 60 years of age. the cohort consisted of 149 patients undergoing RYGB. Anthropometric, biochemical, and clinical evaluations were performed preoperatively and then at 30 and 180 days postoperatively.Results: the average age was 40 years, and the patients were predominately female (72%). At the end of the study period, all groups showed a significant reduction in metabolic syndrome compared with preoperative levels. Logistic regression showed a higher percentage of metabolic syndrome in patients in group 3 after 180 days.Conclusion: There was significant resolution of metabolic syndrome in all groups, independently of the preoperative BMI. However, in group 3 (BMI >= 50 kg/m(2)), 22% of individuals still presented with metabolic syndrome at 180 days postoperatively (P = 0.03).
