I have had numerous blood tests done in the past 6 months (5) for various health insurance inquiries (life, disability, and a "prevention plan" for my group insurer) and I have followed up with my doctor twice due to the results. In each test everything was normal (all liver function tests, kidney, cholesterol, and glucose) except in each test my ALT liver enzyme has been slightly elevated (72, 52, 62, 64, and 68, respectfully). I am a 26 years old male and I am not overweight, I excercise regularly, and I am displaying no symptoms of anything. As far as I can tell I am completely healthy. My doctor has reassured me that this slightly elevated liver enzyme is nothing to worry about, and that we should maybe just keep an eye on it. But, it remains in the back of my mind. I do drink alcohol a little more than I should (probably 15-20 drinks per week, always beer). I am not on any medication and I never have been. I don't know if it's relevant, but I think I may have a minor case of IBS because I sometimes get stomach aches that are relieved by bowel movements (1 every two weeks or so).
