Becoming a Living Kidney Donor: What You Need to Know

​​

What Living Kidney Donation Is

Living kidney donation is when a healthy person donates one kidney while they are alive. The donor keeps one kidney, which usually grows a bit and does the work of both. The transplant center’s job is to make sure you are healthy enough to donate, guide you through surgery, and support you during recovery.

 

Who Can Be a Living Donor?

Most transplant centers share some basic requirements:

• You must be an adult (at least 18; some centers require 21 or older).

• You need generally good physical and mental health.

• Certain conditions—like uncontrolled high blood pressure, diabetes, or cancer—can prevent donation.

• If you smoke, you will likely be asked to quit before you can be approved.

Every center is different, so you should never rule yourself out on your own. If you’re interested, let the transplant team decide if you’re a good candidate. Being turned down at one center doesn’t always mean you’ll be turned down everywhere.

​

Types of Living Donation

There are two main ways to donate a kidney while you’re alive:

• Directed donation
  You choose a specific person to receive your kidney—often a family member, partner, friend, or coworker. This is the most common type of living donation.

• Non-directed (altruistic) donation
  You donate to someone you do not know personally. The transplant team matches your kidney to a patient in need. These donors are sometimes called altruistic or “Good Samaritan” donors.

If you want to donate to someone you know but you’re not a good match, paired exchange may be an option. In a paired exchange, two (or more) donor–recipient pairs “swap” donors so each recipient gets a kidney that matches them better.

​

Benefits of Being a Living Donor (for the Recipient)

As a donor, you don’t gain physical health benefits—but your gift can transform someone else’s life. For the person receiving your kidney, living donation can mean:

• A shorter or no wait on dialysis, sometimes avoiding dialysis completely with a preemptive transplant.

• A better genetic match in many cases, lowering the risk of rejection.

• A kidney that is more likely to start working right away.

• A kidney that, on average, lasts longer than a deceased donor kidney.

• The ability to plan surgery for a time when both of you are as healthy and prepared as possible.

Your decision can give someone freedom from the dialysis chair and a real second chance at life.

​

Risks of Donating a Kidney

Like any surgery, living donation has risks. Short-term risks can include:

• Bleeding or infection near the surgical area

• Hernia if you lift something heavy too soon

• Urinary tract infection after surgery due to the catheter used during the operation

The living donor team will also talk with you about possible long-term risks—such as small changes in kidney function and a slightly higher risk of certain health issues—and will only move forward if they believe the risk is low and acceptable for you.

​

Making the Decision to Donate

Donating a kidney is a deeply personal decision. You should:

• Take time to think and talk it through with people you trust.

• Ask every question you have—no question is too small.

• Remember that you should never feel pressured or guilty, no matter what you decide.

You will have your own dedicated donor team whose only job is to look out for your health and your interests, not the recipient’s. You can change your mind at any time, for any reason, and the team will protect your privacy.

How to Start the Donation Process

If you’re interested in becoming a living donor:

1. Contact a transplant center to begin an evaluation.

   • If you want to donate to someone specific, reach out to their transplant center.

   • If you don’t have a specific recipient in mind, you can contact any transplant center.

2. Complete a 1–2 day evaluation that includes blood and urine tests, imaging (like X-ray or CT scan), and meetings with the donor team.

3. If you are approved, you’ll work with the team to schedule surgery for a time that works for you and the recipient (if there is one).

Most living donor surgeries are done laparoscopically, meaning several small cuts instead of a large incision. Donors usually stay in the hospital 1–2 nights and need about 4–6 weeks to fully recover and return to normal activities.

Life After Donating a Kidney

For most donors, life after donation looks a lot like life before:

• Research shows donors live just as long as people who never donated.

• You do not need lifelong medication just because you donated.

• You don’t need a special diet, though a healthy lifestyle is encouraged.

• You can drink alcohol in moderation if your doctor says it’s okay.

You should protect your remaining kidney—especially during contact sports—and keep up with regular medical checkups. Women are usually advised to wait 6–12 months after donation before becoming pregnant and should work closely with their doctors during pregnancy.

​

Questions to Ask the Living Donor Team

If you’re considering donation, good questions include:

• “What will my evaluation look like, and how long does it usually take?”

• “Will I need someone to stay with me during and after surgery?”

• “What costs are covered, and are there any programs to help with lost wages or travel?”

• “Can you connect me with someone who has already donated at this center?”

• “What will my follow-up care and long-term monitoring look like?”
