Liver cirrhosis is a condition which is characterized by scaring of liver tissue. This scar formation reduces blood flow in liver and liver can not perform functions properly. Cirrhosis of liver can be due to use of alcohol, hepatitis B and C, autoimmune hepatitis, fatty liver, exposure to toxic material and blockage and inflammation of bile duct. Liver cirrhosis is irreversible. You can not reverse the damage but can stop further damage.
Currently there is no cure for it except liver transplant. However, possibly in the future there will be a cure as scientists are searching for one.
