I had a fatty liver and had a biopsy during my open RNY. I just went back for my 3 mo check up (down 80 lbs) and my doc said my liver function still isn't normal but he said it should be when i go for my 6 mo check up. If it isn't then he said I would have to see a specialist but he said he is confident that it will go back to functioning normally on its own.
