Liver Regeneration: The Body’s Remarkable Self-Repair Ability

The liver is the second fastest-healing organ (after the corneal epithelium) and uniquely capable of regenerating lost tissue. After surgical resection or injury, it can regrow up to 75% of its original mass within weeks through hepatocyte proliferation.

This regenerative capacity allows living-donor liver transplants and recovery from significant damage, provided the underlying cause (alcohol, virus, toxin) is removed and sufficient healthy tissue remains.
