Nonalcoholic fatty liver disease (NAFLD) is not a serious condition on its own, but can eventually lead to serious disorders. NAFLD is capable of causing enlargement and damage to the liver (nonalcoholic steatohepatitis), and this in turn can lead to liver scarring and permanent damage (cirrhosis). These can be life threatening, and lead to liver failure. Because of these consequences, NAFLD can become a serious concern if it is combined with behaviors that damage the liver. You can address the seriousness of NAFLD by engaging in behaviors that decrease its risk and effects.
