Hi there, There are a lot of things that can cause your liver enzymes to elevated. As a general surgeon, I often see patients with elevated liver enzymes, and am asked to evaluate them. NASH is a chronic process, and usually your liver enzymes won t be elevated until there is a significant amount of damage done. This means that just because your liver enzymes are normal doesn t mean NASH has resolved. What NASH basically means is that you have a fatty liver, and the fat can damage the liver over time. In terms of your liver enzymes being elevated, you are correct in saying that it was likely due to your illness. Any illness can cause your liver enzymes to be elevated, and this will usually resolve over time. Drugs like acetominophen (tylenol) and alcohol can cause your liver enzymes to be acutely elevated. I think the marijauna, while a better pain reliever than prescription pain meds, didn t cure your liver. Time and stopping the pain meds helped your liver enzymes go back to normal. With patients who have NASH, I recommend a low fat diet, minimal alcohol use (really try to limit it to 2 drinks a week, and cut it out totally if you can), and avoid tylenol use (try to limit to 2grams per day, and only if you absolutely need it). Marijuana won t harm your liver acutely, but we still don t know the long term effects of marijuana on the liver, lungs, and the brain. I hope this answers your question. Feel free to contact me if you have any further questions!
