No, you cannot donate your liver more than once, even though it has the remarkable ability to regenerate after a partial hepatectomy (liver donation).
While the liver does regenerate to nearly its original size and function after a living donor liver transplant (LDLT), the remaining liver needs to fully recover and be dedicated to the donor's health and well-being. A second donation would place an unacceptable risk on the donor.
Here's a breakdown of why repeat liver donation isn't possible:
-
Donor Safety: The primary concern is the health and safety of the living donor. Undergoing a second major surgery to remove a portion of the liver would significantly increase the risk of complications, including liver failure, bleeding, infection, and other surgical risks. The liver needs to maintain sufficient size and function for the donor's long-term health.
-
Regeneration Limitations: While the liver regenerates, it's not an unlimited process. Repeated removal of liver tissue can potentially impair its regenerative capacity over time, leading to chronic liver problems for the donor.
-
Ethical Considerations: Transplant centers prioritize the well-being of living donors. Performing a second liver donation would be considered unethical due to the increased risks and potential long-term health consequences for the donor.
In summary, although the liver can regenerate after a donation, the risks associated with a second donation are too high to consider it a viable or ethical option. Protecting the donor's health is always the top priority in living donor liver transplantation.
