Non-alcoholic fatty liver disease (NAFLD) is caused by fatty infiltration of the liver in the absence of alcohol consumption. The incidence of NAFLD in general population is 30-40%. NAFLD is considered by some authors to be the liver manifestation of the metabolic syndrome and by other authors is considered to be a separate entity. The pathogenesis of NAFLD and metabolic syndrome seems to have common pathophysiological mechanisms, with focus on insulin resistance as a key factor.
