question: Hi, I am Kathy 53 yrs old today. Had blood work done recently for life insurance. My AST was 51 my ALT was 114 and my GGT wa 175. I haven t had a drink in two years and didn t drink but one or two glasses per month before that, of red wine. My BMI is 38.1, high also. Could this be a fatty liver or something more dire?
