Liver Transplant Rejection
What is Liver Transplant Rejection?
Liver transplant rejection happens when your immune system attacks your new liver. Your body sees the transplanted organ as a foreign threat and tries to destroy it. This is a normal immune response, but it can damage or destroy the transplanted liver if not treated quickly.
There are three types of rejection. Acute cellular rejection is most common in the first six months after surgery. Chronic rejection develops slowly over months or years. Hyperacute rejection is rare and happens within hours of transplant. Most rejection episodes can be reversed with medication when caught early.
Around 25 to 50 percent of liver transplant recipients experience at least one rejection episode. Regular blood testing helps doctors spot rejection before serious damage occurs. Monitoring liver enzymes like ALT is the first line of defense in detecting rejection early.
Symptoms
- Elevated liver enzymes on blood tests
- Fever above 100 degrees Fahrenheit
- Yellowing of skin or eyes, known as jaundice
- Dark colored urine that looks like tea
- Light colored or pale stools
- Abdominal pain or tenderness near the liver
- Fatigue and weakness
- Loss of appetite
- Nausea or vomiting
- Itchy skin
Many people have no symptoms in the early stages of rejection. Blood tests often detect rejection before you feel sick. This is why regular monitoring is critical after a liver transplant.

Causes and risk factors
Liver transplant rejection occurs when your immune system recognizes the new liver as foreign tissue. Your T-cells attack the donor organ to protect your body from what it perceives as an invader. Taking immunosuppressant medications helps prevent this response, but rejection can still happen even with proper medication.
Risk factors include missing doses of immunosuppressant drugs, infections that activate your immune system, and genetic differences between you and the donor. Younger recipients and those with autoimmune conditions may face higher rejection risk. The risk is highest in the first three to six months after surgery but remains present throughout your life.
How it's diagnosed
Doctors diagnose liver transplant rejection through blood tests and liver biopsy. Blood work checks liver enzymes like ALT, which rise when the liver is damaged or inflamed. An increase in ALT levels often signals rejection before symptoms appear. Regular monitoring helps your medical team catch rejection episodes early and adjust treatment quickly.
Rite Aid offers ALT testing as part of our flagship blood panel. We recommend regular testing for transplant recipients to track liver function between doctor visits. If blood tests show elevated enzymes, your doctor may order a liver biopsy to confirm rejection and determine the type and severity.
Treatment options
- Increase dosage of existing immunosuppressant medications
- Add high-dose corticosteroids like prednisone or methylprednisolone
- Switch to different immunosuppressant drugs if current ones are not working
- Use anti-thymocyte globulin for severe or resistant rejection
- Take all medications exactly as prescribed without missing doses
- Attend all follow-up appointments and lab testing
- Avoid infections by practicing good hygiene and avoiding sick contacts
- Maintain a healthy diet rich in vegetables, lean protein, and whole grains
- Stay physically active within your doctor's recommendations
- Avoid alcohol completely to protect your transplanted liver
- Report any new symptoms to your transplant team immediately

Frequently asked questions
The first sign is often elevated liver enzymes on routine blood tests. ALT levels rise before physical symptoms appear. Some people develop fever, fatigue, or abdominal discomfort. Jaundice and dark urine may occur in more advanced cases.
Testing frequency depends on how long ago you received your transplant. Most people need weekly or biweekly tests in the first three months. Testing becomes less frequent over time, typically monthly or quarterly after the first year. Your transplant team will set your specific schedule.
Yes, most acute rejection episodes can be reversed with treatment. Doctors typically increase immunosuppressant medications or add corticosteroids. Early detection through blood monitoring gives the best chance of successful reversal. Chronic rejection is harder to reverse and may require retransplantation.
Elevated ALT suggests your liver cells are damaged or inflamed. This could indicate rejection, infection, medication toxicity, or bile duct problems. Your doctor will compare your current ALT to your baseline levels. Additional tests help determine the specific cause.
A liver biopsy is often needed to confirm rejection and assess its severity. Blood tests show something is wrong, but a biopsy reveals exactly what is happening in the liver tissue. The procedure is usually done with a needle under local anesthesia. Results guide your treatment plan.
Common immunosuppressants include tacrolimus, cyclosporine, mycophenolate, and prednisone. Most people take a combination of two or three medications. These drugs suppress your immune system to prevent it from attacking the transplanted liver. You must take them every day for the rest of your life.
Diet and lifestyle cannot prevent rejection on their own. However, healthy habits support your overall health and help medications work better. Avoid alcohol completely, maintain a healthy weight, and stay active. Never skip medications, as this is the leading cause of preventable rejection.
Chronic rejection that does not respond to treatment can lead to liver failure. In this case, you may need another liver transplant. This is called retransplantation. Your transplant team will monitor your liver function closely and discuss all treatment options with you.
Yes, acute rejection is most common in the first three to six months. Your immune system is most reactive during this period. Risk decreases over time but never disappears completely. Lifelong monitoring and medication adherence remain essential even years after transplant.
Infections can activate your immune system and potentially trigger rejection. They can also make it harder to tell if symptoms are from infection or rejection. Both cause fever and elevated liver enzymes. Your doctor will test for infections while monitoring for rejection to ensure proper treatment.
