AI Summary In a 2024 survey of 57 liver transplant recipients, all reported at least one complication, most often elevated liver enzymes (44%), kidney problems (35%), or heart problems (19%).

Medically reviewed.
A liver transplant can restore health and add years of life, but recovery does not end in the operating room. Even years after surgery, transplant recipients can face complications from organ rejection, infection, and the lifelong immunosuppressant medicines that protect the new liver.
This page introduces the most common post-transplant complications — organ rejection, infection, biliary and vascular problems, disease recurrence, diabetes, kidney dysfunction, and cancer risk — so you know what to watch for and when to call your transplant team.

Common Complications After Transplant
Complications can appear early, in the first weeks after surgery, or emerge years later. Your transplant team screens for each of these at every follow-up visit.
Rejection happens when your immune system recognizes the transplanted liver as foreign and attacks it. It is the reason transplant recipients take lifelong immunosuppressant medicines. Rejection can be acute, often within the first year, or chronic, developing gradually over years.
Immunosuppressant medicines protect your new liver but also weaken your defenses against bacteria, viruses, and fungi. Common post-transplant infections include cytomegalovirus (CMV), BK virus, and Candida fungal infections. Hand hygiene, food safety, and prescribed anti-infective medicines lower this risk.
The bile duct connection is a common site of trouble after transplant. Bile can leak at the surgical connection, or the duct can narrow (a stricture) from scarring, sometimes related to reduced blood flow. Symptoms include jaundice, itching, fever, or abdominal pain, usually managed with endoscopy or a drainage procedure.
The blood vessels reconnected during surgery — mainly the hepatic artery and portal vein — can develop narrowing (stenosis) or clots (thrombosis). Hepatic artery thrombosis can reduce blood flow to the liver and bile ducts and raise the risk of infection or graft failure. Most vascular problems are found on imaging and treated with interventional radiology or surgical revision.
The disease that damaged your original liver can sometimes return in the new one. Fatty liver disease, viral hepatitis, and autoimmune liver diseases are among the conditions that can recur, so your transplant team continues to monitor liver enzymes and imaging long after surgery.
Because immunosuppressant medicines lower immune surveillance against abnormal cells, transplant recipients have about 2 to 3 times the risk of a new cancer compared with people of the same age and sex who have not had a transplant. Skin cancer is the most common, accounting for about 40% of these cancers; lymphoma and cancers linked to viruses such as HPV and Epstein-Barr virus are also more common. Routine skin checks, sun protection, and cancer screenings are part of long-term follow-up care.
Metabolic Complications
Two of the most common long-term complications are new-onset diabetes and declining kidney function, both closely tied to the immunosuppressant medicines that protect your graft.
Lifelong immunosuppressant medicines prevent rejection but come with trade-offs. Common side effects across core immunosuppressants (tacrolimus, cyclosporine, mycophenolate mofetil) and steroids include kidney function changes, high blood pressure, tremor, elevated blood sugar, increased infection risk, and changes in cholesterol or triglycerides. Never adjust or stop these medicines without your transplant team's guidance, since under-immunosuppression raises rejection risk.
See Post-Transplant Medication ClassesRegular blood tests and check-ins let your transplant team catch complications early, often before you notice symptoms. Typical monitoring includes liver enzymes and immunosuppressant blood levels, kidney function and blood pressure, blood glucose, lipid panels, and periodic imaging or skin checks. How often you're seen depends on how long ago you had your transplant and your individual risk factors.
Find a Liver SpecialistComplication patterns vary by age, how long ago the transplant took place, and what caused the original liver disease, according to a 2024 survey of 57 liver transplant recipients.
All respondents in the survey reported experiencing at least one post-transplant complication, underscoring why lifelong follow-up care matters no matter how well you feel.
A liver-friendly lifestyle supports your transplanted liver alongside your medicines. Focus on regular gentle movement, a balanced diet low in excess salt and sugar, good hand hygiene, sun protection, and consistent medication timing. Small, steady habits add up over years of living with a transplant.
Three balanced meals a day, food safety habits (thoroughly washing produce, avoiding raw fish, cooking meat well), and keeping a quick, reliable snack on hand can help you stay nourished, especially in the early months when appetite may be low.

Watch for fever, jaundice (yellowing of skin or eyes), dark urine, pale stools, abdominal pain or swelling, fatigue, or a sudden rise in liver enzymes on routine blood tests. Report any of these to your transplant team promptly rather than waiting for your next scheduled visit.
Organ rejection happens when your immune system attacks the transplanted liver as foreign. Acute rejection most often occurs within the first year after surgery, while chronic rejection develops more gradually over years. Lifelong immunosuppressant medicines are used specifically to prevent it.
Yes. Immunosuppressant medicines that prevent rejection also reduce your body's ability to fight off bacteria, viruses, and fungi, including cytomegalovirus (CMV), BK virus, and Candida infections. Many transplant recipients are prescribed anti-infective medicines during the highest-risk periods to help prevent this.
Overall survival after liver transplant is strong, with about 94% of recipients surviving at one year, 81% at five years, and 62% at ten years across all causes of transplant, according to AASLD guidelines. Long-term survival depends on managing complications like rejection, infection, kidney disease, and cancer risk as they arise.
No. Skin cancer, cardiovascular disease, chronic kidney disease, and recurrence of the original liver disease are the leading causes of illness and death in the years after a successful transplant, not just organ rejection. This is why lifelong monitoring covers far more than liver function alone.
