After a kidney transplant, you will need to take rejection medication for the rest of your life. Kidney transplantation is the transplantation of an allogeneic kidney into a patient. Because the autoimmune cells do not recognize the transplanted kidney, a rejection reaction occurs. However, as the transplanted kidney becomes more and more dependent on the recipient, the dosage of drugs will be reduced but not stopped, so kidney transplant patients need to take anti-rejection drugs for life. Kidney transplant patients need to pay attention to prevent chronic rejection. They should take the medication on time and should not stop taking it without authorization. Meanwhile, they should also go to the hospital for regular checkups during the period of taking it to prevent kidney abnormalities. Normally, you can exercise appropriately to enhance your physical fitness. Don’t overwork, don’t stay up late, and prevent respiratory infections. Pay attention to diet, do not smoke, do not drink, choose to eat fresh fruit.
