Steatosis (fatty liver) is an accumulation of fat in the liver. When this progresses to become associated with inflammation, it is known as steatohepatitis. Fatty liver disease is divided into: Alcohol-related fatty liver disease. Non-alcoholic fatty liver disease (NAFLD).
1 Fatty liver disease is characterized by increased accumulation of fat, especially triglycerides, in the liver cells.  It is normal for the liver to contain some fat and by itself, this causes no symptoms. In some patients, the excess fat can cause inflammation called steatohepatitis (steato=fat+hepar=liver +itis=inflammation), although there is no relationship between the amount of fat present and the potential for inflammation.
