What Is a Liver Transplant?

Here's a question worth starting with: why replace the liver at all, rather than repair it? The short answer is that a badly damaged liver can't be patched back to health. When it stops doing its many jobs — filtering blood, making proteins, helping with digestion — the only option that can restore those functions is a healthy liver in its place.

The video at the top of this page introduces liver transplantation in just that way: surgery to remove a diseased or injured liver and replace it with a healthy whole liver, or a segment of one, from another person, called a donor. What follows unpacks the questions people usually ask next.

Who might need one, and where do donor livers come from?

People with either acute or chronic liver failure may need a transplant to survive — that's the framing the video itself uses, and it covers both situations you hear about: a liver that fails suddenly, and one that declines over a long period. Not everyone with liver disease is a candidate, though. Transplant teams assess each person carefully, because donor organs are scarce and the surgery and lifelong follow-up that come with it are demanding.

Donor livers come in two broad forms. A whole liver can come from a deceased donor, allocated through the transplant waiting system. Alternatively, a living donor can give a segment of their liver — the approach followed in this living donor liver transplantation video. The liver is unusual here: a segment can grow, which is part of what makes living donation possible at all.

So what actually happens during the operation?

In theatre, the surgical team removes the failing liver and connects the donor liver — or segment — in its place, joining its blood vessels and bile duct so blood can flow through it and bile can drain as it should. It's major surgery, carried out by a specialist transplant team, and the details vary with whether the graft is a whole organ or a living-donor segment.

Afterwards, monitoring is close, especially early on. The team watches how the new liver is working and how you're recovering, and that hospital phase is only the start. If you've read our guide to kidney transplants, you'll recognise a shared theme across transplant care: the operation is one chapter, and the follow-up is the rest of the book.

What does life look like afterwards?

Recovery is gradual. You'll have regular checks and blood tests so the team can track liver function and adjust your care, and you'll take medicines that prevent your immune system from attacking the new organ — medicines transplant patients generally stay on long-term, exactly as their own team directs. That follow-up isn't a sign something has gone wrong; it's how transplant teams catch small problems early, when they're easiest to address.

It's also worth saying plainly what a transplant is not. It isn't a return to life with no medical care at all — it's a swap of one serious condition for a managed one, with a working liver at the centre of it. For people facing liver failure, that swap can be life-saving, and your own transplant team is the right source for what it would mean in your particular case.

Frequently Asked Questions

Can a living person donate part of their liver?
Yes. A living donor can give a segment of their liver, and the segment can grow after transplantation. Living donation is one route alongside whole livers from deceased donors, and donor and recipient are both assessed carefully by the transplant team.

How long do you stay on transplant medicines?
Generally long-term. Medicines that stop the immune system attacking the new liver are a standard, ongoing part of transplant care, taken exactly as your own team directs, alongside regular checks and blood tests.

Is a liver transplant a cure with no follow-up needed?
No. It replaces a failing liver with a working one, but it brings lifelong follow-up — monitoring, blood tests, and transplant medicines. Think of it as exchanging liver failure for a closely managed condition, not for a life without medical care.
