Find cause: Your physician may repeat this off all rx's, or proceed directly to testing for hepatitis b & c if not done already, hemochromatosis, wilson's, autoimmune hepatitis, and maybe a few others. If all negative, perhaps you're one of those folks for whom heavy-duty aerobic conditioning helps control elevated liver function tests and overall wellness. Good luck.
