The fatty liver disease is usually reversible. The liver has an amazing ability to regenerate itself. Normally, fatty liver disease is caused by malnutrition, alcohol, poisoning, or in some cases pregnancy. Normally, you simply change your diet or stop drinking alcohol and you should see a reversal of it. If it is obesity or nutrition related, your doctor should either help you with a diet, or send you to someone who can help you with a diet. If it is alcohol related, stop drinking or at least cut back on the drinking until you can stop it, or get the pill that makes you sick everytime you get near alcohol to curb the drinking. If it is poison related, then keep a close eye on your wife....j/k. Whatever you do, don't leave it untreated or unchecked because once your skin turns yellow and you go jaundiced, your liver function is severely impaired and then you are in trouble.
