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).
Within this group, some people develop a more serious condition called nonalcoholic steatohepatitis (NASH), in which the liver cells become inflamed and, in some cases, are replaced by scar tissue. Once the scarring, or cirrhosis, occurs, the liver begins to sustain permanent damage. (Source: ACG).
