Cirrhosis is a condition characterized by large areas of scar tissue on the liver. It is often the result of many long-term liver diseases, such as different forms of hepatitis or medical conditions people are born with (these are called congenital conditions). Infections, drug and/or alcohol abuse, or a blocked bile duct can cause cirrhosis as well. Unfortunately, the scarring is permanent; but treatment can stop or slow down further progression and reduce complications.
