Liver cells have a high capacity for regeneration, so the liver can regenerate. However, the specific regenerative capacity of the liver is affected by many factors, such as age and health of the liver. If the age is young and the texture of the liver is good, the regenerative ability of the liver is excellent, and the liver can be improved by regeneration even after mild damage or resection, and can even regenerate effectively even after 80% of the liver has been resected. Liver surgery at this time will not affect the normal function and metabolism of the liver. If you are older or have hepatitis, cirrhosis, etc., the health of the liver declines significantly, then the regenerative capacity of the liver will be significantly reduced, and at most 50% of the liver can be removed, or even not allowed to be removed. Because of the liver’s strong regenerative capacity, both the patient and the donor can live a normal life after liver transplantation, but the regenerative capacity of the liver varies, depending on the individual.
