Currently, the high growth rate of non-alcoholic fatty liver disease (NAFLD) is estimated by the tendency of the population to become obese. However, as the level of obesity increases, the severity of the disease also increases. NAFLD occurs with 30-100% obesity. In NAFLD, most patients (48-100%) are asymptomatic and are detected during general examinations. A nonprogressive form of NAFLD - hepatic steatosis occurs in 40-78% of patients. When the disease progresses periodically, 12-40% of patients may develop non-alcoholic steatohepatitis after 8-13 years, and 15% of patients may develop liver cirrhosis and liver failure. 7% of patients with liver cirrhosis may develop hepatocellular carcinoma after 10 years
