What Is a Living Organ Donor? Understanding the Gift of Life
A living organ donor is one of the rarest kinds of heroes — someone who gives part of themselves so another person can live. Here's what that really means.
February 2, 2026
Most people associate organ donation with the decision marked on a driver's license — a gift given at the end of one life so others may continue theirs. But there is another, rarer path: living organ donation. A living donor chooses, while perfectly healthy, to give a piece of themselves to someone else. This guide explains what that means, what's actually involved, and how to honor someone walking through it.
What is a living organ donor?
A living organ donor is a healthy person who voluntarily donates an organ — or part of an organ — to another person, usually someone facing organ failure. Unlike deceased donation, the donor is awake, recovering, and continuing their life afterward. Roughly 6,000 living donations happen in the United States every year, most commonly kidneys, followed by partial liver donations.
What organs can be donated while alive?
Kidneys — the most common. Humans are born with two and can live a full, healthy life with one.
Liver — a portion is donated; both the donor's and recipient's liver tissue regenerates within months.
Lung lobe, partial pancreas, partial intestine — rare and reserved for specific medical cases.
The donation process
Living donation begins with extensive medical and psychological evaluation, often spanning months. Donors are tested for compatibility, overall health, and emotional readiness. Surgery itself is typically laparoscopic (small incisions), and most kidney donors are discharged within 2 to 3 days. Full recovery takes 4 to 6 weeks.
Donors do not pay for the surgery — the recipient's insurance generally covers all donor medical costs. Lost wages, travel, and lodging may be reimbursed through programs like the National Living Donor Assistance Center.
Who can become a living donor?
Eligibility varies by transplant center, but typically: age 18 or older, in good physical and mental health, with a compatible blood type and no major medical conditions like uncontrolled diabetes or active cancer. You do not need to be related to the recipient.
Life after donation
The vast majority of living donors return to their normal lives with no long-term restrictions. Studies of kidney donors show life expectancy and overall health remain comparable to the general population. Many describe donation as one of the most meaningful experiences of their lives.
How to honor a living donor
Words rarely feel like enough. A small piece of engraved jewelry, a handwritten letter, a meal train through recovery, and remembering the donation date every year afterward all matter. The donor gave something irreplaceable. The least we can do is make sure they know it was seen.
