WOW! There is no other medical or life style that would have caused a fatty liver. I have a new MD and after reviewing my case, including alcohol and other med's, told me that long term us of PPI's can cause a fatty liver. I also told a family member that works in pharmacy and they said yes, it can and they are only meant for short term. Just ask your pharmacists about what the side effects of long term use are. I did do a google search on the matter and it doesn't say much about liver damage but it did mention a side effect of osteoporosis. I was a little shocked by that one. You are to young to have osteoporosis, with out any other medical problems. I'm 48 and I can't imagen having that too. There is a facebook page called nissen fundoplication take down and another that is called nissen fundoplication. You may look there for some much needed support and answers to other question that you may have. You are not alone! Good Luck and God Bless.
