It is scarring of the liver and poor liver function as a result of chronic damage to the liver. With mild cirrhosis, the liver can make repairs and continue its function in the body. However, with more advanced cirrhosis, more and more scar tissues form in the liver which cause the liver to gradually lose its ability to function normally.
There are many causes of cirrhosis. The common causes are chronic alcohol abuse, chronic viral hepatitis B or hepatitis C infection, autoimmune hepatitis, cryptogenic cirrhosis (cirrhosis due to unknown causes), and inherited disorder such as hemochromatosis (abnormal accumulation of iron) and Wilson’s disease (abnormal accumulation of copper).
There is often no sign or symptom until the liver damage is already quite extensive.
