Donating a liver does not in principle affect the donor’s life expectancy, but a small percentage of donors may experience postoperative complications that may affect their life expectancy. When donating a liver, the donor is usually required to have good liver function and no underlying liver disease. In addition, donor livers usually require only a small portion of the liver, with most of the liver still present in the donor’s body. The regeneration and repair ability of liver cells is relatively strong. Generally, if the donor can recover the original volume and size of the liver within six months after the operation and can resume normal function, it will not affect the patient’s normal life expectancy, and he/she can live like a normal person. However, a small number of donors may develop complications such as biliary fistula and hemorrhage after the operation, which may jeopardize the donor’s life and health and shorten his/her life expectancy if not dealt with effectively.
