Life After a Liver Transplant

Problems after transplant arise from several sources: rejection (the immune system attacking the graft, as the new liver is called), infection because of reduced immunity, side effects of medicines (kidney problems, high blood pressure, high blood sugar, high cholesterol, tremor, bone thinning), narrowing or clotting in the blood vessels or bile ducts of the new liver, and return of the original liver disease (for example hepatitis B or C, fatty liver or autoimmune disease). Missing doses of medicine is one of the most important avoidable causes of rejection.

Most people who have a liver transplant need to take anti-rejection medicines for the rest of their lives. Some degree of rejection or other complications can occur at any time, but most can be treated if found early.

Because anti-rejection medicines must be taken at set times, discuss with your team before fasting in Ramadan whether fasting is advisable for you and how to time your doses; do not change timing on your own. For Umrah, Hajj or other travel, ask about infection precautions, vaccines and carrying a supply of medicines with a letter from your team.

Follow-up is frequent at first and gradually becomes less frequent. Blood tests check liver tests, kidney function, blood counts and the level of your anti-rejection medicines. If tests are abnormal, ultrasound or other imaging and sometimes a liver biopsy (a small tissue sample taken with a needle) are used to find the cause, such as rejection, infection or bile duct narrowing. Your team also screens for the side effects of treatment, such as diabetes, high blood pressure, high cholesterol, kidney problems, bone thinning and skin cancer, and checks for recurrence of the original liver disease.

Your daily habits protect the new liver.

• Take anti-rejection medicines at the same times every day, never skip, never stop on your own, and never change brands or forms without telling the team.

• Do not run out: keep a stock, and order refills early, especially before travel, Ramadan and holidays.

• Wash hands often, avoid close contact with sick people, and keep vaccinations up to date; live vaccines are generally avoided, so check first.

• Protect your skin from the sun, use sunscreen and have regular skin checks.

• Do not drink alcohol or smoke, and keep a healthy weight; stay active with regular exercise as advised.

• Keep a medicine card or list with you and tell every doctor, dentist and pharmacist that you have had a transplant.

A balanced diet protects your weight, bones, kidneys and blood sugar, and food safety is important because your immunity is lower.

• Eat a balanced diet with vegetables, fruit, whole grains, lean protein and enough calcium.

• Limit salt, sugar and saturated fat to help control blood pressure, blood sugar and cholesterol.

• Avoid grapefruit, pomelo and Seville orange, and ask your pharmacist about other foods or herbs, because some change the level of anti-rejection medicines.

• Avoid raw or undercooked meat, fish and eggs, unpasteurised milk and cheese, and wash fruit and vegetables well.

• Do not use herbal, traditional or "liver detox" supplements without checking with your team.

Anti-rejection medicines are the most important part of your care. The team chooses the combination, adjusts the amounts based on blood levels and may change them over time.

• Medicines commonly used include tacrolimus, mycophenolate, everolimus and corticosteroids, alone or in combination, as decided by your team.

• Blood tests to check the medicine level are usually taken before your morning dose; follow the team's instructions on timing.

• Before taking any new medicine, including antibiotics, painkillers, herbal products or over-the-counter products, check with the transplant team or pharmacist, because many interact.

• Report side effects early, since often the plan can be adjusted.

• Women who may become pregnant should talk to the team before conceiving, as some medicines must be changed first.

Most people do not need further operations, but some procedures may be needed if problems arise.

• Liver biopsy can confirm rejection or other causes of abnormal tests.

• Narrowed bile ducts or blood vessels can often be opened with endoscopic or radiology procedures.

• Regular screening procedures, such as colonoscopy and skin checks, are recommended by your team.

• A repeat transplant is considered only in rare cases when the new liver fails.

Many centres try to use the lowest effective level of anti-rejection medicine to protect the kidneys and lower side effects, and they individualise this. Researchers are studying ways to detect rejection earlier with blood tests and to reduce reliance on medicines in selected patients, but these approaches are not routine and should only be used under the guidance of the transplant team.

Many people enjoy a good quality of life, return to work and family life, and may even have healthy pregnancies with specialist planning. Long-term success depends on taking medicines every day, attending follow-up, protecting yourself from infections, and living a healthy lifestyle. Your team can explain what to expect in your own case.

• Which medicines must I take, at what times, and what if I miss a dose?

• How often do I need blood tests and clinic visits?

• Which over-the-counter and herbal products are unsafe for me?

• Which vaccines should I have or avoid?

• Is it safe for me to fast, travel or plan a pregnancy?

• Whom do I call urgently if I feel unwell?
