My brother has Hep C and is not overweight, but has a lot of vomiting, fevers, chills, night sweats, etc. He has a lot of pain in his upper right quadrant as well. He doesn't have a fatty liver, but more of a scarred liver. He is being put on an experimental thing involving Milk Thistle in large quantities at a hospital in Philadelphia. Milk Thistle is supposed to help cleanse the liver, maybe talk to your doctor about it, and speak with someone specializing in hep c who knows all the ins and outs.
Cirrhosis can be suggested in the ultrasound, and if it's not seen, it's an unlikely diagnosis. That said, the most definitively test would indeed by a liver biopsy. But, given the clinical picture, this does not present like a typical cirrhotic patient.
Non-alcoholic fatty liver, or NASH, is best treated with lifestyle changes, including weight loss.
If the diagnosis continues to be non-revealing, another referral can be sought with a GI physician.
