Predictive factors to estimate the severity of nonalcoholic fatty liver disease in candidates for Roux-en-Y gastric bypass.

Objectives: Non-alcoholic fatty liver disease (NAFLD) is related to obesity, insulin resistance, dyslipidemia, and metabolic syndrome. The increasing prevalence of NAFLD results in a significant number of patients manifesting chronic liver disease over time. The aim of this study was to analyze the predictive factors to estimate NAFLD severity in patients who are candidates for Roux-en-Y gastric bypass.

Methods: The sample consisted of women aged 20-65 years submitted to Roux-en-Y gastric bypass with monitoring equal to or higher than 24 months.

PRE- AND POSTOPERATIVE IN BARIATRIC SURGERY: SOME BIOCHEMICAL CHANGES.
