Liver steatosis: The new epidemic of the Third Millennium. Benign liver state or silent killer?

Until the end of the 90's of the last century, rather little attention was paid to the issue of the non-alcoholic fatty liver disease (NAFLD), perhaps due to the fact that the newly discovered hepatitis C virus did attract a paramount interest of hepatologists and researchers. On the other side, fatty liver was considered a relatively uncommon cause of liver damage, occurring almost exclusively in obese females, often associated with non-insulin dependent diabetes mellitus (NIDDM), and with a relatively benign prognosis. Due to the complexity of international available guidelines, we decide to approach the main unsolved issues on this topic in the form of a dialog between a hepatologist and a man suffering from NAFLD, trying to give evidence-based answers to the more frequently asked questions from patients and their GPs. This is the third instalment of the Trilogy of Dr. Calm, a skilled hepatologist who will try to clearly explain to his patient Mr. Frightened the natural history of NAFLD, the diagnostic workup, indications for liver biopsy and suggested medical treatments, advicing him on the importance of dietary intervention and lifestyle modifications.
