Important anti-rejection medications, Cyclosporine and Tacrolimus, can also decrease kidney function. Immediately after surgery, medications will be carefully adjusted to allow your kidneys to function as well as possible. If necessary, dialysis will be performed until your kidneys recover function. The process of your immune system trying to fight off the new liver is called rejection. Rejection is a normal response of your immune system to the transplanted organ.
Many patients experience an episode of rejection at one point or another after transplant.
Medicine is given to prevent your immune system from rejecting your new liver. Blood tests are also done to measure liver function. If the blood test results are abnormal liver biopsies may be performed to look at the liver tissue under the microscope. However, an abnormal liver test could mean something other than rejection. There are many ways for your doctor to treat a rejection episode.
