I assume you've been checked for hepatitis A,B&C. Have you been evaluated and followed by a hepatologist or a gastroenterologist? Has nonalcoholic faffty liver disease been unequivocally ruled out? Has any of your test given the estimated fat content of your liver?Has a liver biopsy been recommended? Perhaps seeing a hepatologist at a university hospital for a 2nd opinion would be advisable.
