You can also go to the top of the page, there is a magnifying glass icon, click on that, type in NAFLD and you will see others searching for help.
It can be reversible, from what I have read, diet and exercise play an important role.
I am sorry that your doctor has not let you know what you can do to help yourself.
I hope you can find more help.
