I have mildly elevated AST and ALT levels for over a year, with no identified cause. My recent blood work shows AST: 40 (ULN: 34) and ALT: 66 (ULN: 41), along with elevated BUN: 27 (ULN: 23) and a BUN/Creatine Ratio. I had a CT scan that showed no signs of fatty infiltration, blockage, or enlargement, and all hepatitis and autoimmune tests were negative. I have a history of mild obesity, symptomatic gallstones, and a family history of cryptogenic cirrhosis. My weight is currently normal, and I rarely drink alcohol or take Tylenol. Could I have non-alcoholic fatty liver disease (NAFLD) despite my normal weight and CT scan? What else could be causing the elevated liver enzymes?
