John needs a kidney. You could be the one who saves his life.

Living with one kidney is something thousands of people do safely every year. The remaining kidney grows slightly larger and takes on most of the work of two. Long-term studies of living donors show life expectancy comparable to people who never donated.

You will need to avoid contact sports and certain anti-inflammatory medications afterward, and you'll have lifelong follow-ups. Your transplant team walks you through every risk before you commit.

Most living donors leave the hospital in 2 to 3 days. Back to desk work in 2 to 4 weeks. Back to full physical activity in 6 to 8 weeks. The surgery is laparoscopic — small incisions, minimal scarring.

The donor pays nothing for the medical side. The recipient's insurance covers your testing, surgery, hospital stay, and follow-up. This is federal law.

What's not always covered: lost wages during recovery, travel, childcare. The National Living Donor Assistance Center exists specifically to help with these.

Yes. That's the entire point. John is enrolled in paired kidney donation. The program is specifically designed for healthy donors who don't match a specific patient.

Your kidney goes to someone who matches you. Their donor — who matches John — gives John his kidney. Both transplants happen on the same day.

Yes. At any point. No pressure, no judgment. The program will give you a private medical reason if you need to withdraw without explaining to family or friends.

Maybe, maybe not. The screening is the only way to know. Common ranges are 18 to 70, no uncontrolled high blood pressure, no diabetes, no kidney disease of your own, BMI typically under 35. Talk to the team — some conditions disqualify you, some don't, some you can fix.

Share this page with someone who can. Most donors heard about their patient from a friend, not a hospital. You forwarding this URL to ten people in your network may be the action that finds John his match.
