Nonalcoholic fatty liver disease involves the build-up of fat in the liver of people who drink little or no alcohol. It is a common condition. NAFLD may not cause any problems if it is mild. In some cases, it can cause inflammation and scarring in the liver. If this is severe, it can cause liver failure.
