A liver transplant is an operation to remove a diseased or damaged liver from the body and replace it with a healthy one.
It is recommended when the liver has been damaged to the point that it cannot perform its normal functions and is likely to fail.
Read more about why you might need a liver transplant.
Although fairly common, a liver transplant is a major operation. One of the biggest risks is that the body will reject the new organ. To prevent this from happening, you will have to take medication to suppress the immune system for the rest of your life.

The liver can become damaged as a result of illness, infection or alcohol. This damage causes the liver to become scarred, which is known as cirrhosis.
Some of the most common causes of liver damage and cirrhosis are:
Once cirrhosis reaches a certain level, the liver gradually loses all of its functions. This is known as liver failure, or end-stage liver disease.
The only hope for the long-term survival of a person with liver failure is a liver transplant.
There are three types of liver transplant:
Read more about how a liver transplant is performed.
Survival rates can be influenced by a number of factors, including:
The long-term use of immunosuppressants can also cause a wide range of side effects and make a person more vulnerable to infection.

The number of people who need a liver transplant is much higher than the number of livers donated.
For adults, the average waiting time for a liver transplant is around 142 days, and for children it is about 78 days.
It is estimated that in the past 20 years, the number of people who could benefit from a liver transplant has increased by 90%, but the number of available donations has remained the same.
Consequently, deaths from liver disease remain high.
You will be contacted by staff at the liver transplant centre as soon as a suitable liver becomes available. It will need to be the right size and match your blood group.
The call could be at any time during the day or night, so you may be given a bleeper to alert you. If necessary, you may be given transport to the transplant centre.
It is important not to eat or drink anything from the time the transplant centre contacts you.
Once you arrive at the transplant centre, you will be given a chest X-ray and an electrocardiogram (ECG) so that your heart and lung function can be reassessed. You will then be given a general anaesthetic in preparation for the transplant.
The most common type of liver transplant is an orthotopic transplant, where a whole liver is taken from a recently deceased donor.
The surgeon will make a cut in your abdomen and remove your liver. The donor liver will then be put in position and connected to your blood vessels and bile ducts (small tubes that move bile out of the liver).
After the donor liver is in place, the incision will be sealed using dissolvable stitches. Drainage tubes will be attached to drain away extra fluids, and they will usually remain attached for several days after surgery.
Once the transplant has been completed, you will be moved to an intensive care unit (ICU) to recover.
During a living donor transplant, the donor will have an operation to remove either the left or right side (lobe) of their liver.
Right lobe transplants are usually recommended for adults. For children, left lobe transplants are recommended. This is because the right lobe is bigger and better suited for adults, while the left lobe is smaller and better suited for children.
After the donor operation, your liver will be removed and replaced with the donor's liver lobe. Your blood vessels and bile ducts will then be connected to the liver lobe.
Following transplantation, the transplanted lobe will quickly regenerate itself. In most cases of living donor transplants, the new lobe will grow to 85% of the original liver size within a week.
A split donation may be carried out if a donor liver becomes available from a recently deceased person, and you and a child are both suitable candidates for a donation.
The donated liver will be split into the left and right lobes. Normally, you will be given the larger right lobe and the child will receive the smaller left lobe.
A number of liver transplant units have performed successful split donation transplants in two adults, although the adult receiving the smaller left lobe usually has to be much smaller than average for the transplant to be successful.
A liver transplant becomes necessary when the liver has been damaged to such an extent that it cannot perform its normal functions. This is known as liver failure.
Although liver failure can usually be managed by medication for a short while, a liver transplant is currently the only cure.
Unlike the kidney, heart or lungs, there is no mechanical device, such as a dialysis machine, that can replicate the function of the liver.
There are two main ways that a liver can fail:
Every time you drink alcohol, your liver filters out the poisonous alcohol from your blood. Each time your liver filters alcohol, some of the liver cells will die.
The liver can grow new cells, but if you drink heavily for many years, your liver will lose this ability and the dead cells will build up and scar your liver (cirrhosis).
If too much of your liver becomes scarred, it will lose its ability to function and liver failure will occur.
In most cases of alcoholic liver disease, you will have no symptoms until liver failure occurs.
Hepatitis C is a bloodborne virus that you can catch if you come into contact with the blood or, less commonly, body fluids of someone who is infected. Drug users sharing needles are at particular risk.
The virus can cause swelling and scarring of the liver tissue. In some cases it causes significant liver damage.
An estimated one in seven people who contract hepatitis C will have liver failure, often 20 to 30 years after contracting the initial infection.
Primary biliary cirrhosis (PBC) is a type of long-term liver disease thought to be caused by a build-up of bile inside the liver. Bile is a liquid produced inside the liver that helps the body digest fats.
PBC is a relatively rare condition, but it is one of the most common reasons why a person requires a liver transplant.
Hepatitis B is a less common type of viral hepatitis that can be spread during unprotected sex or by sharing needles.
An estimated 2-10% of people will go on to develop a chronic (long-term) infection where the virus stays in their body, although they may not necessarily have any symptoms.
Without treatment, an estimated 15-25% of people with chronic hepatitis B experience liver failure.
Primary sclerosing cholangitis (PSC) is a type of liver disease that causes long-lasting inflammation of the liver. It usually leads to liver failure.
PSC is a rare condition that affects about 1 in 16,000 people. It usually occurs in people who are 30-50 years old.
Autoimmune hepatitis is a rare cause of long-term hepatitis. The white blood cells attack the liver, causing inflammation and damage. This can lead to more serious problems, such as liver failure. The reason for this reaction is not known.
Biliary atresia is a rare childhood condition where babies are born with blockages in their bile ducts. This leads to a build-up of bile, similar to PBC, which results in scarring and, eventually, liver failure.
Biliary atresia affects only 1 in every 18,000 births, but is the most common reason why a child would need a liver transplant.
Liver cancer is a rare and aggressive type of cancer.
There is a strict assessment process that decides who can have a liver transplant, as donated livers are scarce around the world.
Transplant centres use a scoring system to calculate the risk of a person dying if a transplant is not performed.
Assessing your quality of life can be a subjective process. However, the following signs and symptoms represent a decline in quality of life that many people would find intolerable:
The assessment of your likely survival rate is based on your individual circumstances and associated factors, such as:
A number of tests will also be carried out to assess your health and your likelihood of survival.
These tests can include extensive investigations of your heart, lungs, kidneys and liver, as well as checking for any signs of liver cancer.
It is unlikely that you will be offered a liver transplant if you have two or more of the following conditions:
A liver transplant will not be offered if you have any of the following conditions:
Additionally, a liver transplant will also not be offered if you are:
Because of the lack of available livers, it is rarely possible to have a liver transplant as soon as it is needed, so it is likely that you will be placed on a transplant waiting list.
Depending on the clinical need for a liver transplant, you will be placed either on a high-priority or medium-priority waiting list. Many people are well enough to stay at home until a liver becomes available.
The transplant centre will need to be able to contact you at short notice, so you must inform staff of any changes to your personal contact details. You should also inform staff if there are changes to your health – for example, if you develop an infection.
While waiting for a donated liver to become available, it is important that you stay as healthy as possible by doing the following:
The average waiting time for a liver transplant is 142 days for adults and 78 days for children.
However, your waiting time may be a lot shorter if you are on a high-priority waiting list. In some circumstances, you may be able to shorten your waiting time if a relative, or possibly a friend, has the same blood type as you and is willing to take part in a living donor liver transplant.
If your child needs a liver transplant, you may also wish to discuss the possibility of taking part in a living donor liver transplant with staff at the transplant centre.
Prepare an overnight bag and make arrangements with your friends, family and your employer so that you can go to the transplant centre as soon as a donor liver becomes available.
It is possible for a planned transplant to be cancelled, for example because your health deteriorates to such as an extent that a transplant would no longer be safe or effective. You should discuss this possibility with the staff at your transplant centre and, if necessary, with friends, family and loved ones.
The stress of living with a serious liver condition can be bad enough, so the added anxiety and pressure while waiting for a liver to become available does not make the situation any easier.
Because of this extra stress, it is common for potential candidates for a liver transplant to have depression.
One study found that around one in four people waiting for a liver transplant had symptoms of moderate to severe depression.
Signs that you may be depressed include:
It is important not to neglect your mental health as this can have an adverse effect on your physical health.
If you think you may be depressed, contact your doctor for advice.
Shohanna Newman-Kidd likes dancing, running and painting rainbows, but she's had to fight hard to enjoy doing what other children take for granted.
Shohanna was born in 1998 without a bile duct, a condition called biliary atresia, which meant her liver couldn't work properly and poisons were building up in her system. When she was just four weeks old, Shohanna had the first of two operations designed to correct the problem.
Her mother Deloris Newman recalls how her daughter's treatment dominated everything: "She was on 12 medications, some three times a day. I had to mix a special feed for her and insert a feeding tube through her nose and into her stomach. We hardly got out at all. She developed rickets too as a result of her liver problems."
When Shohanna was two-and-a-half, her health deteriorated. "The doctors said a liver transplant was urgently needed. Within five days of her going on the transplant list, we had a late night call to say there was a liver for her," says Deloris.
"We'd thought we might have to wait for years and I felt we were going ahead of other children who'd been waiting longer, but we were assured that it was all about who was the best possible match."
Shohanna had a split liver transplant. She received the smaller lobe of a liver while the larger part was transplanted into an adult patient.
"I'm very proud of how she's coped. She understands what's happened to her, knows about healthy eating and is happy to try any new food. She also understands that she has to take it easy sometimes when her friends are racing about. She's even fine with the bitter taste of the steroids and immunosuppressants. Sadly, she has developed eczema, which is another battle for her, but she manages."
Deloris admits that when Shohanna was in hospital for her operations it was hard to imagine her going on outings, or taking part in school sports days. "Every day was a bonus then. The doctors didn't expect her to do so well, but she showed us all."
Once your liver transplant is complete, you will be moved to an intensive care unit (ICU).
A ventilator will assist you with your breathing. A tube will be inserted through your nose and into your stomach to provide you with nutrients and fluid. These tubes can normally be removed after a few days.
After the transplant, you are likely to be in some pain. You will therefore be given pain relief as required.
Most people are well enough to move out of the intensive care unit (ICU) and into a hospital ward within a few days of having a liver transplant. They can leave hospital within two to three weeks.
Recovering from a liver transplant can be a long, slow process. Aim to gradually build up your health and fitness. It may take three to six months before you are ready to return to work and resume normal activities.
After a liver transplant, one of the biggest risks is that your immune system will not recognise the new liver and begin to attack it. This is known as rejection.
Read more about rejection and liver transplant complications.
To prevent rejection, you will be required to take medicines that suppress your immune system. These medicines are called immunosuppressants.
As the risk of rejection is highest in the first three months after a transplant, it is likely that you will initially be given a relatively high dose of immunosuppressants.
Your dose will then be reduced to a level thought high enough to prevent your immune system rejecting your new liver, but low enough to minimise unpleasant side effects.
To assess how well the immunosuppressants are working, it is likely that you will be given regular blood tests when you first start taking them.
Achieving the balance between preventing rejection and minimising side effects can be challenging. It may take several months before the optimal dose for you is achieved.
Two main types of immunosuppressants are used to treat people after a liver transplant:
Each type of medication is discussed in more detail below.
Calcineurin inhibitors work by blocking the effects of a protein called calcineurin, which is responsible for activating a type of white blood cell known as T cells. The immune system uses T cells to fight infection.
Blocking the effects of calcineurin should mean that your immune system will not send T cells to attack the tissue of your new liver.
The two most widely used calcineurin inhibitors are ciclosporin and tacrolimus, which can be given either in tablet or capsule form, or as an injection.
Common side effects of ciclosporin and tacrolimus include:
For a complete list of side effects and interactions with other medicines, see the Medicines information section on [ciclosporin].
Although these side effects may be troublesome, you should never stop or reduce the recommended dose of immunosuppressants because it could lead to your liver being rejected.
Always check with your pharmacist or doctor before you begin taking any other medication.
Corticosteroids can penetrate the wall of immune system cells. Once inside the cells, corticosteroids can "switch off" the genes responsible for releasing many of the chemicals that the immune system would otherwise use to attack your new liver.
A widely used corticosteroid in liver transplant patients is prednisolone.
Common side effects of prednisolone include:
For a complete list of side effects, see the Medicines information section on [prednisolone].
The long-term use of corticosteroids can also lead to more serious side effects. Read more information about the side effects of corticosteroids.
Around 1 in 20 people have serious mental health symptoms while taking prednisolone, such as:
If you experience any of these symptoms, contact your doctor or a member of your care team immediately. If this is not possible, telephone your local out-of-hours service.
When Gordon Bridewell was rushed from the West Country to London on New Year's Eve 1975 to undergo a pioneering liver transplant, he was also travelling into the record books.
For Gordon, now 59, is the UK's longest surviving liver transplant patient and one of the world's top 10 longest living liver transplant recipients.
It started with a minor injury during a football match. "A tiny lump appeared on my leg and it ached when I walked. I was keen on sport, so I went to my doctor," says Gordon.
After an operation to remove it, Gordon started having blackouts and hallucinations. One theory was that his liver had not filtered out the anaesthetic. Before he could return to work, his doctor recommended a precautionary visit to King's College Hospital in London for further tests.
"At King's they did about 20 to 30 tests. I wondered what I was doing there, I felt fine. Then the consultant told me what I had – a tumour on my liver."
The tumour was removed, but tests revealed a second one, which was inoperable. The specialists suggested a liver transplant.
"I was shocked. I still hadn't recovered from the news about the second tumour. I knew kidney transplants were being done but I'd not heard about liver transplants, except as a last resort, and mostly for elderly people."
"It was a waiting game – I had four false alarms, arriving in London to find that the organs weren't compatible." Enquiries were extended to the rest of Europe to find a suitable match.
In December 1975, Gordon was called for another potential transplant. The 12-hour operation was led by Roy Calne (now Professor Sir Roy Calne), who performed the first liver transplant in Europe in 1968. Waking up immobile and attached to a host of tubes, Gordon was determined to get back on his feet, despite 30 external stitches and even more internal ones. He has nothing but praise for the support and skill of the team involved in his transplant.
He recovered well and returned to work after 13 months: "Two hours a day with a pocketful of tablets – those hours were like a lifetime," he says. "I still had a tube attached to me to take out bile until the new liver functioned properly. I had to empty it two or three times a day."
Gordon soon started doing sports again. In 1980 he trained for the Ross-on-Wye 100-mile raft race and became the first transplant patient in the UK to compete in it. Over the years, he has also counselled people from around the world to help them prepare for their liver transplant.
Gordon is grateful to his donor and proud to be the longest surviving liver transplant patient in the UK: "It makes me honoured and privileged. Every New Year's Eve it all floods back and I always celebrate. I'm so glad to be here."
"The operation changed my whole life – I'd only been given five months when the suitable liver became available. I talk to many people about becoming a donor and ask them what if your son or daughter needed an organ transplant?"
Gordon thinks his sense of humour has played a part in helping him keep well, but it would take a lot to beat his first full meal after his operation: "I was really looking forward to it and the nurse lifted the lid and gasped 'I can't give you this!' It was liver and onions!"
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, such as diabetes.
It is common for the immune system to attack the new liver. This occurs in up to 40% of cases, typically in the first 7-14 days after the transplant.
Symptoms of liver rejection include:
Most cases can be successfully managed by altering your dose of immunosuppressants.
Immunosuppressants make you more vulnerable to infection. You will be particularly vulnerable to:
As a precaution, you will usually be given a course of antifungal medication, such as fluconazole, to take for several months after your transplant.
Symptoms of these types of fungal infection will depend on what part of your body is affected, but may include:
More serious fungal infections can also develop inside your body, such as in the lungs (fungal pneumonia) or bloodstream.
The symptoms of even a minor infection can rapidly get worse and can lead to fatal complications if you are taking immunosuppressants. You should see your doctor or transplant team as soon as possible if you notice the symptoms of a fungal infection.
As a precaution against cytomegalovirus (CMV), you may be given a course of antiviral medication to take for several months after your transplant.
Symptoms of a CMV infection include:
Contact your doctor or transplant centre as soon as possible if you think you have a CMV infection.
After a liver transplant, there is a risk of conditions that affect the biliary tract, including:
These can usually be treated with an endoscopy. A short, wire-mesh tube called a stent can be inserted to allow bile to flow more freely. In some cases, further surgery is needed.
Type 2 diabetes is a common and potentially serious complication of a liver transplant. It affects an estimated one in five people.
Symptoms of diabetes include:
Exactly why liver transplant patients have an increased risk of developing diabetes is unclear. But more than half of all cases of diabetes that develop after a liver transplant are in people with a history of hepatitis C.
Kidney failure is another common and serious complication that affects one in five people with a liver transplant, usually within five years.
Kidney failure happens when the kidneys lose their function and are no longer able to filter out waste products from the blood.
It is thought the main cause of kidney failure is a side effect of the calcineurin inhibitor type of immunosuppressant. These medicines are known to damage the kidneys in certain people.
Symptoms of kidney failure include:
Graft failure is a medical term meaning that the transplanted organ is not working properly. It is one of the most serious complications of a liver transplant and occurs in 1 in 14 cases.
The most common cause of graft failure is a disruption to the blood supply to the transplanted liver caused by blood clots (thrombosis). This includes:
Other causes of graft failure include:
In many cases, however, no obvious cause can be found.
A person with graft failure will deteriorate rapidly and can have a range of symptoms, ranging from muscle spasms to double vision, eventually leading to a coma.
While medication can stabilise the body in the short term, the only cure is to transplant a new liver into the body.
Post-transplant lymphoproliferative disorder (PTLD) is an uncommon and serious complication occuring in around 1 in 50 people who have had a liver transplant.
PTLD is a general term used to describe a range of symptoms caused by the Epstein-Barr virus infecting white blood cells, which in turn can lead to abnormal growths spreading throughout the body.
PTLD typically occurs in the first year after a transplant, although it can develop at any time.
Symptoms of PTLD include:
PTLD is a serious complication as it can cause multiple organ failure and death. An estimated 40% of people who develop PTLD after an organ transplant will die from the condition.
PTLD is treated by temporarily withdrawing the immunosuppressants and using antiviral medication to fight off the underlying viral infection.
People with a transplanted liver have an increased risk of developing some types of cancers, such as:
It is thought this increased risk is a side effect of taking immunosuppressants.
The risk of skin cancer is particularly high – a person with a transplanted liver is thought to be 20 times more likely to develop skin cancer than the population at large.
Because of this increased risk, if you have had a liver transplant you should avoid prolonged exposure to sunlight or artificial forms of ultraviolet light, such as sunbeds or sun lamps. Regular check-ups with a dermatologist (skin specialist) will probably be recommended.
