Liver transplant
A liver transplant is an operation to remove a diseased or damaged liver and replace it with a healthy one.
There is a strict assessment process that is used to decide who can have a liver transplant, as donated livers are scarce both in the UK and around the world.
Due to the lack of available livers, it's rarely possible to have a liver transplant as soon as it's needed, so you'll usually be placed on a waiting list.
You will be contacted by staff at the liver transplant centre as soon as a suitable liver becomes available.
Recovering from a liver transplant can be a long, slow process, but most people will eventually be able to return to most of their normal activities and have a good quality of life.
Complications of a liver transplant can include rejection, an increased risk of infection, graft failure, biliary conditions and a higher risk of developing certain conditions.
