Fatty liver disease (FLD) is the general term applied to a collection of diseases where there is an accumulation of excess fat in the liver. FLD is a common, often “silent” disease that may cause inflammation and damage to the liver.
There are two basic categories of fatty liver disease, depending on whether alcohol has caused the problem. Non-alcoholic fatty liver disease (NAFLD) occurs if the fatty liver was caused by metabolic conditions unrelated to alcohol. Non-alcoholic steatohepatitis (NASH) may be occur if fat accumulation is severe. If alcohol is involved, then the disease is called alcoholic fatty liver disease (AFL); alcoholic steatohepatitis (AH) refers to its more severe version.
