  • Question:What is fatty liver disease?
  • Answer:
    NAFLD: When too much fat is present in the liver of someone who doesn’t drink much alcohol, this is called “Nonalcoholic Fatty Liver Disease” or “NAFLD”. A little bit of fat in the liver is normal, but when too much of it accumulates, it can damage the liver.


    NASH: When too much fat causes significant damage to the liver, this is called “Nonalcoholic steatohepatitis” or “NASH”. “Steato” means fat and “hepatitis” means inflammation and damage in the liver.


    By these definitions, everyone with NASH has NAFLD, but not everyone one with NAFLD has NASH. NASH is the worst type of NAFLD because it can cause scar tissue to build up in the liver to the point of cirrhosis and liver failure.
