Weight Loss and Non-alcoholic Fatty Liver Disease: Falls In Gamma-Glutamyl Transferase Concentrations are Associated with Histologic Improvement

Background: The ability for aminotransferase levels to track histological features of non-alcoholic fatty liver disease (NAFLD) with weight loss has not been examined. Methods: We examined the effect of weight loss following laparoscopic adjustable gastric banding surgery on the histological features of NAFLD and plasma aminotransferase concentrations (AST, ALT and GGT) in 60 (12M, 48F) selected severely obese patients. All 120 paired biopsies...
