[Clinical features of NASH].

Nonalcoholic fatty liver disease (NAFLD), including simple steatosis and nonalcoholic steatohepatitis (NASH), is commonly associated with metabolic syndrome. Many of NASH patients do not have subjective symptoms. The NASH is often found by routine health checkups etc. It is difficult to distinguish the simple steatosis and the NASH by transaminase level. It is reported that 25% of the NASH patient progress to cirrhosis in a decade. However, there is no study by a lot of patients concerning the prognosis of the NASH, and further studies will be required in the future.
