A liver transplant is the replacement of your liver with one that has been donated by someone else. The donated liver comes from someone who has died. In the future, it may be more common for donated liver tissue to come from a living person, such as a family member. In this case, you receive only a part of the donor's liver.
A number of diseases can directly damage the liver. Damage to the liver can seriously affect the absorption of vitamins and nutrients, prevent waste products from being effectively removed from the system, and reduce the production of proteins needed to clot the blood. If the damage is severe enough, transplantation may be necessary. A transplant provides a patient with a liver that can keep up with the demands of a full, active life.
