Cirrhosis is a chronic, progressive disease in which the functions of the liver are gradually lost as normal liver tissue is replaced by scar tissue. Damage to the liver occurs from a virus, a poison, or disease. As part of the healing process, scar tissue forms and replaces normal liver cells and tissue. As liver function is gradually lost, some or all of these signs of liver disease may appear:
Cirrhosis is ultimately a terminal condition. Although there are treatments that may slow down damage to the liver, the liver will eventually fail to respond to these treatments. When this occurs, liver transplantation may be indicated.
Common causes of cirrhosis in the adult are chronic hepatitis, primary sclerosing cholangitis, primary biliary cirrhosis, hepatic vein thrombosis, chronic alcohol abuse, and cryptogenic or unknown causes.
