Hepatitis C (HCV) is the most common form of viral hepatitis. Hepatitis is inflammation or swelling of the liver. If a person has symptoms (many do not), often it is like symptoms of the flu.
Nonalcoholic fatty liver disease (NAFLD) happens when your liver stores too much fat and it is not related to heavy alcohol use. Nonalcoholic steatohepatitis, or NASH, is a more severe form of nonalcoholic fatty liver disease that causes inflammation, called hepatitis, and liver cell damage.
Cirrhosis is permanent damage to the liver by chronic diseases, such as viral hepatitis, NAFLD or long-term alcohol abuse.
