I have hepatitis C and I'm notice one thing on my blood work my ALT levels keep going up and down why is this it will be high one year then normal?

No telling. I am very glad that you're taking a proactive approach to your health and following your values. Truth be told, hepatitis c is a chaotic system, more or less active at any time like the weather. I'm going to assume that you're not taking other meds; even an Ibuprofen tablet or two can raise it. I wish you the best and hope that new work in hepatitis c care will help you.
