With a new liver, you should feel more energetic and healthy because your body is functioning properly again. Hopefully, you will also have a longer lifespan.
According to the Organ Procurement and Transplantation Network, for transplants performed between 1996 and 2001:
Survival rate after 1 year is 88.1%
Survival rate after 3 years is 79.7%
Survival rate after 5 years is 74.3%
Transplant recipients who have hepatitis C have slightly lower-than-average survival rates after 3 years. These rates are still higher than those for a person with hepatitis C who is referred for transplant but doesn't get one. The 5-year survival rate for these persons is only 30% to 50%.
