NAFLD (Non-Alcoholic Fatty Liver Disease) includes all fatty liver diseases from simple steatosis, characterized by excessive lipid accumulation, to more severe hepatic diseases. NAFLD is considered as the hepatic manifestation of metabolic syndrome, which is defined notably by increased waist circumference, insulin resistance and dyslipidemia.

The hepatic steatosis has a benign prognosis but for 30% of case, it can progress to a more severe form of NAFLD, which is called non-alcoholic steatohepatitis (NASH). Steatohepatitis presents steatosis, signs of inflammation and hepatocyte injury with or without fibrosis. This can later lead to cirrhosis, liver failure and hepatocellular carcinoma. According to the American Liver Foundation, 10-24% of the American population develops NAFLD and approximately 8.6 million people have developed NASH.
