My doctor told me I have chronic parenchymal liver disease. I don't have Hep A, B, C. I drink alcohol in moderation. Is this reversible?

Liver disease. The answer you have been given so far is incomplete. The dr. is telling you that you have liver disease, but not what the cause of the liver disease is. Just because you do not have viral hepatitis does not mean that you do not have liver disease. I would stop drinking alcohol completely for now, until you have answers. You need further testing by a gastroenterologist to sort this out. Good luck.
