Why do i have slightly elevated liver enzymes at times and not other times? docs have looked for hep. and many other things. going on 10 years.

Elevated LFTs: Without more details, it is hard to say. Levels that are no more than twice normal yield a different list of possibilities than if they are , say, 10x normal. Low elevations may be due to medications and/or supplements you take, metabolic conditions, or a long list of other causes. Inherited disorders are also possible. Consult a hepatologist.
