I Have Fatty Liver That Is Now Cirrhosis Non Alcoholic.

I have fatty liver that is now cirrhosis non alcoholic. My 17yr old daughter complains of upper abdominal pain after eating anything with red dye. Also see feels nausea, loss of appetite on and off and she is losing weight. Sometimes she gets diarrhea. She was anemic and she gets dehydrated. I had her liver checked and everything was fine. The doctor put her on prolesec and she is worried about her weight. The doctor thought maybe she has a ulcer? Before her period she gets real pale, her blood level is 13 for cbc iron. My father was a alcoholic and my mother was addicted to Tylenol with codine. I'm not sure if she took it while pregnant with me? Should I have my daughter checked for hep C?
