Possible Liver Transplant Complications

People who receive a liver transplant may develop complications after surgery. Your transplant team will help you understand the warning signs of possible complications, discuss your care, and recommend further treatment when necessary.


Rejection is the most common complication following transplant surgery. It happens when the immune system, which defends the body against foreign agents such as viruses or bacteria, treats a transplanted organ as foreign and will try to attack it. To prevent your body from rejecting your new liver, you will take medications called immunosuppressants to suppress the immune response that rejects the foreign tissue.


As a liver transplant recipient, you will be more susceptible to infection because you will take immunosuppressant medications to help prevent rejection. The risk of infection from bacteria and viruses is greatest in the early period after transplant, when immunosuppresant dosages are at their highest.

Hypertension (High Blood Pressure)

Many transplant recipients take medications to control hypertension or high blood pressure, since prednisone and cyclosporine, two of the medications used to prevent rejection, can raise blood pressure.

Renal (Kidney) Dysfunction

Some of the medications that patients are required to take after transplant to prevent rejection can have an adverse effect of the kidney's filtering function. The transplant team will use caution when considering the use of other drugs that can also be toxic to the kidneys in light of the potential adverse effects of the transplant medications.

Hyperlipidemia (High Cholesterol)

Hyperlipidemia can occur early post-transplant due to the effects of cyclosporine and Prograf. Patients may be placed on a cholesterol-lowering medication immediately following transplant for lipid control.

Post-Transplant Diabetes

Some of the immunosuppressant medications that you take may increase your risk of developing diabetes. Diabetes is an increased level of sugar in your blood. Signs of diabetes may include excessive thirst, frequent urination, blurred vision, drowsiness, or confusion. Notify the transplant team if you notice any of these signs. In some cases, high blood sugar can be reduced and managed by weight loss, careful diet and exercise. However, you may need an oral diabetes drug or insulin injections. If you develop diabetes, you will be educated on how to deal with this problem.

Cytomegalovirus (CMV)

Cytomegalovirus (CMV) is a very common virus. About 70 percent of adults have been exposed to CMV at some time. It usually causes a flu-like illness with fever, general body aches, and decreased appetite which lasts two or three days. After exposure to the CMV virus, your body forms antibodies in your blood to protect you from future exposures to CMV. This is similar to what happens after you have chicken pox. We are able to do blood tests to check both the transplant recipient and donor for the presence of CMV antibodies.

Because of the immunosuppressant medications, you will be at risk for infection with CMV after transplant. During the first few months, while the immunosuppressant doses are highest and your immune system is especially weak, the CMV virus can reactivate or "wake up." A CMV infection can range from flu-like symptoms to more serious infections involving your stomach and lungs (pneumonia).

If either you or your donor were positive for CMV antibodies, you will be given antiviral medications for the first few months after transplant. As your doses of immunosuppressants are lowered over time, your risk of CMV will decrease and the medication will be stopped. If you develop an active CMV infection again, you will be treated with IV medications.
