Liver Transplant

Introduction

A liver transplant is a major surgery in which a diseased liver is replaced with a healthy liver, or a portion of a healthy liver, from a donor. For people with advanced liver disease, certain liver cancers, or sudden liver failure, transplant can be a life-saving option when other treatments are no longer enough.

If you or someone in your family has been told that a liver transplant may be needed, you are likely facing a lot of new information at once — how the waiting list works, the difference between deceased and living donor transplants, what the surgery involves, how long recovery takes, and what life looks like afterwards. This guide walks through each of these topics in plain language. It is written for people who are being evaluated for transplant, are on the waiting list, or are in the early months or years after surgery, as well as for the family members supporting them.

A transplant is not a single event. It is the start of a long-term relationship with a specialised medical team, with regular check-ups, lifelong medication, and close attention to your health. Understanding what to expect at each stage helps you take part in the decisions ahead.

What Is a Liver Transplant?

The liver is the largest internal organ in the body. It sits in the upper right side of the abdomen, just under the ribs. It carries out hundreds of essential jobs — cleaning toxins from the blood, producing bile to help digest food, storing energy, making proteins that help blood clot, and supporting the immune system. When the liver is badly damaged, the body cannot easily replace these functions, and serious illness follows.

A liver transplant, also called hepatic transplantation, is the surgical replacement of a failing liver with a healthy one. The new liver may come from a deceased donor (someone who has died and whose family has consented to organ donation) or from a living donor (usually a close family member who donates part of their own liver). The liver has a unique ability to regenerate — both the portion left in the living donor and the portion placed in the recipient grow back to a near-normal size over weeks to months.

A liver transplant is considered when medical treatments can no longer control liver disease, when complications of liver failure become life-threatening, or when certain liver cancers cannot be treated effectively in other ways. It is not a first-line treatment. It is reserved for situations where the benefits of transplant outweigh its considerable risks and where a person is healthy enough overall to undergo major surgery and lifelong follow-up.

Types of Liver Transplant

Liver transplants are generally grouped by the source of the donor liver. The decision about which type is appropriate is made by the transplant team based on the recipient's condition, urgency, donor availability, and other medical factors.

Deceased-donor liver transplant

In a deceased-donor liver transplant, the whole liver comes from a person who has died and whose family has agreed to organ donation. In most cases, this is someone who has been declared brain-dead while their heart is still functioning with support, which allows organs to be retrieved in good condition. In some programmes, donation after circulatory death is also possible.

Deceased-donor livers are allocated through a national or regional waiting list. Patients on the list are prioritised based on how sick they are, not how long they have been waiting. The most widely used measure of urgency is the MELD score (Model for End-Stage Liver Disease), which uses simple blood tests to estimate how severely the liver is failing. Patients with higher MELD scores generally move higher on the list. In India, deceased-donor allocation is coordinated through state and national organ transplant registries under the framework of the Transplantation of Human Organs and Tissues Act.

Living-donor liver transplant

In a living-donor liver transplant, a portion of the liver is taken from a healthy living person and transplanted into the recipient. Because the liver regenerates, both the donor's remaining liver and the transplanted portion grow over the following months to take on full function.

In adult-to-adult transplants, the right lobe of the donor's liver (the larger side) is usually used. In adult-to-child transplants, a smaller portion (the left lateral segment) is generally enough.

Under Indian law, living donors are typically close relatives — parents, siblings, children, spouse, or grandparents. Donation by other related or unrelated persons is possible only with the approval of a state-level authorisation committee, which exists to confirm that the donation is voluntary and not for any form of payment. Selling or buying organs is illegal.

Living-donor transplant has several practical features. The surgery can be planned rather than waiting for a deceased-donor organ to become available. Wait times can be shorter, which matters when liver disease is progressing quickly. However, it involves a major operation for a healthy person — the donor — with its own risks, and the donor evaluation is rigorous.

Split-liver and other variants

In some situations, a deceased-donor liver is divided so that two recipients — often an adult and a child — can each receive a portion. This is called a split-liver transplant. Specialised programmes may also offer domino transplants or other variants in particular medical conditions. These approaches are less common and are decided on a case-by-case basis by the transplant team.

Why Is a Liver Transplant Performed?

Liver transplant is considered when the liver is failing and no other treatment can restore enough function. The underlying conditions that lead to transplant fall into a few broad groups.

End-stage chronic liver disease (cirrhosis)

Cirrhosis is the scarring of the liver that results from years of injury. As scarring builds up, the liver cannot work properly. Common causes of cirrhosis that lead to transplant include:

• Chronic hepatitis B and hepatitis C infections. Newer antiviral medications have changed the picture for many patients, but advanced damage that has already occurred may still progress.
• Alcohol-related liver disease. Transplant is generally considered after a period of confirmed abstinence and supportive care, in line with current programme criteria.
• Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH), increasingly common causes of cirrhosis linked to obesity, diabetes, and metabolic syndrome.
• Autoimmune liver diseases, such as autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis.
• Genetic and metabolic conditions, such as Wilson's disease, hereditary haemochromatosis, and alpha-1 antitrypsin deficiency.

Liver cancer

Hepatocellular carcinoma (the most common primary liver cancer) may be treated with transplant when the cancer is confined to the liver and meets specific size and number criteria. The Milan criteria are widely used internationally, with some centres applying expanded criteria. Transplant in this setting treats both the cancer and the underlying cirrhosis that often coexists.

Acute liver failure

Acute liver failure is a sudden, severe loss of liver function in a person without prior chronic liver disease. Causes include certain drug reactions, paracetamol (acetaminophen) overdose, acute viral hepatitis, and unknown causes. When this happens, transplant may be the only life-saving option, and patients are usually placed at the top of the waiting list.

Other indications

Less commonly, transplant is considered for certain bile duct cancers, large benign liver tumours that cannot be resected, severe complications of polycystic liver disease, and some inherited metabolic disorders in which the liver itself is structurally normal but produces or fails to process certain substances correctly.

Who Is a Candidate?

Not everyone with advanced liver disease is suitable for transplant. The evaluation aims to identify patients for whom transplant offers a meaningful chance of long-term benefit and who can tolerate the surgery and lifelong follow-up.

Evaluation typically includes:

• Detailed assessment of liver function, including blood tests, imaging (ultrasound, CT, or MRI), and sometimes biopsy.
• Heart and lung evaluation, because the surgery and anaesthesia place significant strain on these organs.
• Screening for infections and for cancers outside the liver.
• Kidney function tests, since kidney disease often accompanies advanced liver disease.
• Nutritional assessment.
• Psychological and social evaluation, including support at home and, where relevant, assessment of substance use and recovery.
• Dental evaluation, because untreated dental infections can cause problems after transplant.

Conditions that may make transplant inadvisable include active uncontrolled infection, cancer outside the liver that has spread, severe heart or lung disease that would not survive the surgery, and active substance use that has not been addressed. Some of these are absolute, while others are relative and may be reconsidered if circumstances change.

Age alone is not a strict cut-off in current practice. Older adults with otherwise good health may be considered, while younger patients with significant other illnesses may not. Each transplant programme has its own criteria, and the team's judgment of overall fitness matters more than a single number.

Alternatives to Liver Transplant

Before transplant is recommended, doctors typically try to manage liver disease and its complications with other treatments. Even when transplant is being planned, these treatments often continue to keep a patient as well as possible while waiting.

• Antiviral medications for hepatitis B and C have transformed outcomes for many patients and, in earlier disease, can stop or even reverse damage.
• Lifestyle and metabolic management — weight loss, control of diabetes, treatment of high cholesterol — can slow or improve fatty liver disease.
• Abstinence from alcohol, with structured support, is critical in alcohol-related disease and can lead to meaningful recovery in earlier stages.
• Medications to manage complications of cirrhosis, such as diuretics for fluid build-up, beta-blockers for variceal bleeding risk, lactulose and rifaximin for hepatic encephalopathy, and ursodeoxycholic acid for some cholestatic diseases.
• Procedures to manage complications, such as endoscopic banding for variceal bleeding, drainage of fluid (paracentesis), and TIPS (transjugular intrahepatic portosystemic shunt) for portal hypertension.
• Liver-directed cancer treatments, such as surgical resection, radiofrequency or microwave ablation, transarterial chemoembolisation (TACE), and radioembolisation, may be options for some liver cancers depending on tumour size, number, and liver function. These can sometimes be used as a bridge while waiting for transplant.

When these treatments can no longer maintain reasonable quality of life or when survival without transplant becomes limited, transplant becomes the focus of care.

Preparing for a Liver Transplant

Preparation begins long before the day of surgery. It involves medical preparation, listing or donor work-up, and practical and emotional preparation.

Listing for deceased-donor transplant

After evaluation, suitable patients are placed on a waiting list. While waiting, regular check-ups continue. Blood tests are repeated periodically to update the MELD score, since priority can change as the disease progresses. Patients are advised to remain reachable at all hours, keep a small bag ready, and avoid travel that would prevent reaching the hospital within a few hours of being called.

Waiting times are unpredictable. Some patients receive an organ within weeks; others wait many months. Living-donor transplant may be discussed as an alternative if a suitable donor is available within the family.

Living-donor evaluation

When a family member is being considered as a living donor, they undergo their own detailed evaluation. This protects the donor by confirming that they are healthy, that their liver anatomy is suitable, and that donating a portion of the liver is safe for them. The evaluation includes blood tests, imaging of the liver and its blood vessels, heart and lung assessment, and psychological evaluation. The donor's consent must be entirely voluntary, and the donor can withdraw at any time without any consequences to their care.

Staying as healthy as possible

While waiting, patients are usually advised to:

• Follow the team's dietary plan, which often emphasises adequate protein and calories, salt restriction in those with fluid retention, and fluid limits in some.
• Stay as physically active as their condition allows, since better fitness before surgery supports better recovery afterwards.
• Avoid alcohol and any non-prescribed medications, including herbal supplements, that could affect the liver.
• Keep all routine immunisations up to date as advised by the team, since some vaccines cannot be given after transplant.
• Address dental issues before transplant when possible.
• Report any new symptoms promptly, such as fever, confusion, worsening jaundice, vomiting blood, or black stools.

Practical and emotional preparation

Major surgery and a long recovery affect the whole family. It often helps to plan ahead for time off work, childcare, and household tasks. Many patients and families benefit from talking to others who have been through the process, from peer support groups, or from the hospital's social work and counselling team.

What Happens During the Surgery

For the recipient:

• General anaesthesia is given, and several lines and tubes are placed to monitor and support the body during surgery.
• A long incision is made across the upper abdomen, often in a shape sometimes called a Mercedes-Benz incision.
• The diseased liver is carefully separated from surrounding blood vessels and the bile duct, and removed.
• The donor liver is placed in position. The main blood vessels (the inferior vena cava, portal vein, and hepatic artery) are connected. The bile duct is then joined either directly to the recipient's bile duct or to a loop of small intestine.
• The team confirms good blood flow and bile drainage, places drains, and closes the abdomen.

In a living-donor transplant, two operations happen in parallel — one to remove the portion of liver from the donor, and one to place it in the recipient. The timing is coordinated so that the donor liver is transferred with as little delay as possible.

The first days in intensive care

In the ICU, the breathing tube is usually removed within a day or two once the patient is stable. Pain is managed with medications. Frequent blood tests check that the new liver is working, that bleeding has stopped, and that infection is not developing. The team watches for early signs of rejection or complications and starts immunosuppressive medications to prevent rejection.

The hospital ward

Once stable, patients move from ICU to a transplant ward. Eating, drinking, and walking start gradually. Drains and lines are removed as they are no longer needed. The medication routine is taught in detail — both to the patient and to the family member who will help at home. A typical hospital stay is around two to four weeks, although this varies widely and may be longer if complications arise.

The first three months at home

The first three months are the most critical period for rejection and infection. Frequent clinic visits and blood tests are usual — sometimes twice a week at first. Energy returns slowly. Walking, light activity, and a balanced diet are encouraged. Heavy lifting and strenuous activity are usually restricted for several weeks to allow the abdominal wound to heal.

Many patients find this period harder emotionally than they expected. It can feel slow, and minor setbacks — a small rise in a liver enzyme, a mild infection — can be frightening. The transplant team supports patients through this phase, adjusting medications and providing reassurance.

Three to twelve months

Most patients gradually return to many of their normal activities through this period. Energy continues to improve. Driving usually resumes when off strong pain medication and able to brace safely for an emergency stop, generally weeks after surgery. Return to work depends on the type of job and varies from a few months for office work to longer for physically demanding roles. Clinic visits become less frequent as long as everything is stable.

Living donors

For living donors, recovery is shorter but still significant. Most donors are in hospital for about a week and return to office-type work in around six to eight weeks. The remaining liver regenerates substantially within a few months, although follow-up continues for a longer period. Donors do not need lifelong medication.

Risks and Complications

Liver transplant is a major operation, and complications are possible during surgery, in the early weeks, and over the longer term. The transplant team works to prevent, detect, and treat these as early as possible.

Surgical complications

• Bleeding, which may require return to the operating room.
• Blood clots in the hepatic artery or portal vein, which can affect the new liver.
• Bile leaks or bile duct narrowing, which may need endoscopic procedures or further surgery.
• Wound infections or hernia at the incision over time.

Rejection

Rejection happens when the immune system identifies the new liver as foreign and attacks it. Acute rejection most often occurs in the first weeks to months. It is usually detected on blood tests before causing symptoms and is treated by adjusting immunosuppressive medications. Most episodes respond well. Chronic rejection is less common with current medications.

Infection

Because immunosuppression reduces the body's ability to fight infection, transplant recipients are more vulnerable to bacterial, viral, and fungal infections. Cytomegalovirus (CMV) is a particularly important virus that the team screens for and treats. Preventive medications are given for several months after surgery.

Side effects of immunosuppression

The medications that prevent rejection have side effects that vary by drug and dose. These can include high blood pressure, kidney impairment, raised blood sugar or new-onset diabetes, raised cholesterol, tremor, headache, gum overgrowth, hair changes, and an increased long-term risk of certain cancers, particularly skin cancers. The team monitors for these and adjusts medications over time to balance protection against rejection with side effects.

Recurrence of underlying disease

Some of the conditions that led to transplant can affect the new liver. Hepatitis B and C can recur, although effective antiviral treatments now greatly reduce this risk. Autoimmune diseases may recur in a minority of patients. Fatty liver disease can develop in the new liver if metabolic factors are not addressed. Cancer can recur, particularly in the first few years. Surveillance is part of long-term follow-up.

Donor risks

Living donation is a major operation for a healthy person. Most donors recover well, but donors face risks including bleeding, bile leak, infection, blood clots, and, very rarely, more serious complications. Transplant programmes evaluate donors carefully to keep these risks as low as possible and follow donors for a defined period afterwards.

Life After a Liver Transplant

For most people who have a successful transplant, life gradually returns to a sense of normality, often with improvements in energy, appetite, and overall well-being compared with the months before surgery. Living well with a transplanted liver, however, involves ongoing care.

Immunosuppression for life

Anti-rejection medications must be taken every day, on time, for life. Skipping doses, even briefly, can trigger rejection. Most patients take a combination of medications in the first months, which is usually reduced and simplified over time as the risk of rejection falls. Common medications include tacrolimus, cyclosporine, mycophenolate, and corticosteroids. The team adjusts doses based on blood tests.

Follow-up and monitoring

Regular blood tests check liver function, kidney function, blood sugar, cholesterol, and drug levels. Imaging may be repeated periodically. Vaccinations are kept up to date, although live vaccines are generally avoided. Skin checks, dental care, and screening for common cancers are part of long-term health maintenance.

Diet, alcohol, and lifestyle

A balanced diet, regular physical activity, and a healthy weight all support long-term liver and overall health. Salt restriction may continue if there are concerns about blood pressure or fluid balance. Food safety becomes important because of immunosuppression — recipients are usually advised to avoid raw or undercooked meat and fish, unpasteurised dairy, and certain other foods. Alcohol is generally discouraged, and is strictly avoided where the original disease was alcohol-related.

Work, travel, and relationships

Most people return to work and to their usual activities. Travel is possible, with planning around medications, vaccinations, and access to medical care at the destination. Intimate relationships and sexual function often improve as overall health returns. Pregnancy after transplant is possible for many women, but should be planned with the transplant and obstetric teams because of medication and timing considerations.

Mental and emotional health

Many transplant recipients describe a complex mix of gratitude, relief, anxiety, and at times guilt — particularly toward a deceased donor's family or a living donor. Anxiety about rejection or infection is common, especially in the first year. Counselling and peer support can be valuable. Family members, who often carry significant stress during the waiting and recovery period, may also benefit from support.

Liver Transplant in Children

Children can also undergo liver transplant, often with excellent long-term outcomes. The causes of liver failure in children differ from those in adults. The most common indication is biliary atresia, a condition in which bile ducts do not develop normally. Other indications include inherited metabolic diseases, certain liver tumours, acute liver failure, and progressive familial cholestasis.

The surgery and immediate recovery follow similar principles to adult transplant, adjusted for the child's size. Specialised paediatric transplant teams, with paediatric anaesthetists, surgeons, intensivists, and hepatologists, manage these cases.

Long-term care in children includes attention to growth, development, schooling, and gradual education of the child about their own medications and health as they get older. Adolescence is a recognised period of higher risk for missed medications, and transplant teams work closely with families during the transition to adult care. With good long-term care, many children who receive a transplant grow into healthy adults.

Frequently Asked Questions

How long does a transplanted liver last?

Many transplanted livers function for decades. International studies generally describe survival of around 85 to 90 percent at one year after transplant and around 70 to 75 percent at five years, with outcomes continuing to improve over time. Individual outlook depends on the underlying disease, age, other health conditions, and how well the transplant goes. Your transplant team can provide an estimate based on your specific situation.

Will I need to take medication forever?

Yes. Anti-rejection medication is taken every day for life. The number and dose of medications is usually highest in the first months and is reduced over time. Taking medication exactly as prescribed is one of the most important things a transplant recipient does.

Can I live a normal life after transplant?

Most transplant recipients return to work, family life, travel, and recreation, often feeling significantly better than they did before transplant. “Normal” includes lifelong medications, regular check-ups, and some adjustments around food safety, infection precautions, and sun protection. Within those, full and active life is the usual goal.

Is living-donor transplant safer for the recipient than deceased-donor?

Both can have excellent results. Living-donor transplant offers the advantages of planned timing and shorter waiting, which can be important when liver disease is progressing quickly. Deceased-donor transplant uses a whole liver, which has some technical advantages. The right choice depends on the recipient's condition, donor availability, and the transplant team's assessment. It is not a question of one being universally safer than the other.

What are the risks for a living donor?

Most living donors recover well and return to normal life. The operation is major, however, and risks include bleeding, bile leak, infection, blood clots, and, very rarely, serious complications. Donor evaluation is rigorous specifically to keep these risks as low as possible. Donors are followed up after the surgery to confirm that their liver has regenerated and that they remain well.

Can I drink alcohol after transplant?

Alcohol is generally discouraged, and is strictly avoided if the original liver disease was alcohol-related. Even for other recipients, alcohol can interact with medications and stress the new liver. Most transplant teams advise abstinence.

Can the same disease come back in the new liver?

For some conditions, yes. Hepatitis B and C can recur but are now usually well controlled with antiviral medication. Autoimmune liver diseases can recur in some patients. Fatty liver disease can develop in the new liver if metabolic factors such as obesity and diabetes are not managed. Cancer can recur, particularly in the first few years. Long-term follow-up looks for these so they can be addressed early.

How is a donor matched to a recipient?

For liver transplant, the main factors are blood group compatibility and body size, so that the donor liver fits well and supplies enough function. Detailed tissue typing, as required for some other organ transplants, is not generally needed for liver. The transplant team considers all these factors when allocating a deceased-donor organ or assessing a potential living donor.

Can someone be a living donor for me if they are not a relative?

Under Indian law, living donation is generally limited to close relatives. Donation by other individuals is only allowed with approval from a state-level authorisation committee, which exists to confirm that the donation is voluntary and not connected to any form of payment. Any form of paid donation is illegal.

What happens if my body rejects the new liver?

Acute rejection is usually picked up on routine blood tests before symptoms appear. It is treated by adjusting immunosuppressive medications, often with a short course of higher-dose steroids. Most episodes respond well. Severe or chronic rejection that does not respond to treatment is uncommon with current medications but, when it occurs, may eventually require re-transplantation.

Conclusion

A liver transplant is one of the most significant treatments in modern medicine. For people whose livers can no longer support life or whose disease cannot be controlled in other ways, it offers a real chance at long, active years ahead. It is also a long journey — evaluation, waiting, surgery, and lifelong follow-up — that involves the patient, the family, and a specialised team working together over many years.

Understanding the types of transplant, the reasons for considering it, what the surgery involves, how recovery unfolds, and what life looks like afterwards helps patients and families take part in the decisions ahead with clearer expectations. Every transplant journey is individual, and the most important conversations are the ones you have with your transplant team about your particular situation, your options, and your goals.
