Overview
Fatty liver is a type of liver disease, characterized by inflammation of the liver with concurrent fat accumulation in liver ("steato", meaning fat, "hepatitis", meaning inflammation of the liver). Classically seen in alcoholics, steatohepatitis also is frequently found in people with diabetes and obesity. When not associated with excessive alcohol intake, it's referred to as non-alcoholic steatohepatitis, or NASH. Steatohepatitis of either etiology may progress to cirrhosis, and NASH is now believed to be a frequent cause of unexplained cirrhosis.
Pathophysiology
Fatty liver is the fatty degeneration of the parenchymal cells causing a yellow discoloration of the liver. It is a reversible condition where large vacuoles of triglyceride fat accumulate in liver cells via the process of steatosis. Despite having multiple causes, fatty liver disease (FLD) can be considered a single disease that occurs worldwide in those with excessive alcohol intake and those who are obese (with or without effects of insulin resistance). The condition is also associated with other diseases that influence fat metabolism[1]. Morphologically it is difficult to distinguish alcoholic FLD from non alcoholic FLD and both show micro-vesicular and macrovesicular fatty changes at different stages.
