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 alcoholism. 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. Each time your liver is injured, it tries to repair itself. In the process, scar tissue forms. As cirrhosis progresses, more and more scar tissue forms, making it difficult for the liver to function.
Decompensated cirrhosis is the term used to describe the development of specific complications resulting from the changes brought on by cirrhosis. Decompensated cirrhosis is life-threatening.
The liver damage done by cirrhosis generally can't be undone. But if liver cirrhosis is diagnosed early and the cause is treated, further damage can be limited and, rarely, reversed.
