Cirrhosis of the liver is an irreversible livershrinkage in which liver tissue is destroyed leading to scars in the tissue. This reaction is caused by various liver diseases that have not healed for several years.
If too much functional tissue is destroyed, the performance of the liver is impaired. If the disease is not treated, it can lead to death by a breakdown of all functions of the liver. In the case of advanced liver shrinkage, about 40 to 60 percent of those affected die within one year. As the main cause of this disease is excessive alcohol consumption and hepatitis, alcoholics who overcome their addiction have the best chances of recovery (50 percent of liver cirrhosis caused by alcohol abuse, 30 percent of liver shrinkage caused by hepatitis).
