What is the life span of a person with a liver disease? Is there a cure for a person with a liver disease?

Diseases of the liver are a major cause of morbidity and mortality.The answer to your question I think depends on the extent of disease that is affecting the liver.

Cirrhosis of the liver is common, this is when the organ develops fatty infiltrates due to chronic alcoholism. The efficiency is damaged and normal physiology is lost. Cirrhosis may or may not develop into fulminant liver failure. Some people live with this condition for many years.

Liver failure, on the other hand, is almost always fatal. The damaged organ losses elasticity and becomes unable to filter toxins from the blood. These toxins accumulate, ammonia levels rise intravascularly, delirium soon follows as does coma and death. In addition, coagulopathies develop which lead to hemorrhage, the patient slowly bleeds to death.
