Globally, fatty liver disease affects 15 to 40% of the general population. NASH affects 10-20% of patients with fatty liver and incidence increases with weight gain. Although having fat in the liver is not normal, it usually causes no problems or permanent damage. If fatty liver is suspected based on blood test results or scans of the liver, this problem is called nonalcoholic fatty liver disease (NAFLD). When a liver biopsy is performed, it will show that some people have NASH while others simply have fatty liver. There are currently no medicines available to treat patients with NASH.
