- Cirrhosis is a late stage of scarring (fibrosis) of the liver caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcohol abuse. The liver carries out several necessary functions, including detoxifying harmful substances in your body, cleaning your blood and making vital nutrients.
- Cirrhosis occurs in response to damage to your liver. The liver damage done by cirrhosis can’t be undone. But if liver cirrhosis is diagnosed early and the cause is treated, further damage can be limited. As cirrhosis progresses, more and more scar tissue forms, making it difficult for the liver to function (decompensated cirrhosis). Advanced cirrhosis is life-threatening.
