Things You Must Know About Being a Living Kidney Donor
A person may want to donate a kidney to a family member, friend or, in some cases, someone they do not know. While most healthy people can live normally with one kidney, they should understand that donation involves surgery and carries risks before making a decision.
Prior to approval, a prospective donor undergoes a thorough medical and psychological evaluation. The goal is simple: to ensure donation is relatively safe for the donor and the kidney is appropriate for the transplant.
Who Can Become a Living Kidney Donor?
A living donor is usually an adult who is healthy enough to undergo surgery and live comfortably with one kidney remaining. In India, the law requires a person to be at least 18 years old to donate a kidney. But there is no age limit for kidney transplants that automatically qualifies someone to donate.
Eligibility Criteria
The kidney transplant team considers a person’s overall health rather than focusing on a single test or figure. Things to consider may include:
- General physical health and age
- Kidney function and urine protein
- Cardiovascular health and blood pressure
- History of blood sugar and diabetes
- Weight and general metabolic health
- Previous medical illnesses and operations
- Compatibility of blood groups and tissues
- Ability to grasp risks and to provide informed consent
Important Consideration A potential kidney donor also must feel comfortable with the decision. Donations should be voluntary and not under pressure from family members, the recipient or anybody else. |

Common Medical Exclusions
Certain conditions may make donation unsafe. These can include significant kidney disease, serious uncontrolled heart or lung disease, some cancers, active infections and certain uncontrolled metabolic conditions. The exact criteria vary across transplant centres.
This variability is also why the age limit for kidney transplants should not be viewed as a simple cutoff. An older person may be considered if their overall health and kidney function are suitable, while a younger person may be declined if donation could place their health at unacceptable risk.
The Living Donor Evaluation Process
The evaluation is deliberately thorough because the donation is performed on a healthy person. The transplant team needs to understand both the immediate surgical risks and the donor's longer-term health.
Medical Tests and Screening
A potential living donor may undergo:
- Blood and urine tests to assess kidney function
- Blood pressure measurement
- Blood group and tissue compatibility testing
- Tests for infections
- Heart and lung assessment
- Imaging of the kidneys and urinary system
- Assessment of blood sugar and other health markers
- Additional cancer screening where appropriate
In India, NOTTO's donor criteria include kidney function testing, urine protein assessment, infection screening and imaging as part of donor evaluation.
What Happens During Kidney Donation Surgery?
Once the evaluation is complete and the donor is approved, surgery is planned with the transplant team. The kidney is removed under general anaesthesia and prepared for transplantation into the recipient.
Types of Donor Surgery: Open vs. Laparoscopic
Most centres use minimally invasive or laparoscopic methods when they are suitable. The surgeon makes a few small cuts and uses special tools to remove the kidney. However, sometimes you have to do an open operation.
The specific surgical procedure depends on the anatomy of the donor, the transplant centre and the surgeon’s judgement.
Recovery Timeline
Recovery varies from person to person. Many donors remain in hospital for a few days and gradually return to normal activities over the following weeks. Donors may return to their pre-donation activities in around four to five weeks, although recovery can take longer for some people.
During recovery, rest, short walks, adequate nutrition and following wound-care instructions can help. Also, heavy lifting should be avoided until the surgical team confirms that it is safe.
Risks and Long-Term Health Effects of Donating a Kidney
Most donors remain healthy, but some may have a slightly higher risk of high blood pressure or kidney problems. Individual risk depends on overall health and kidney function before donation.
| Risk | What to know |
|---|---|
| Pain and discomfort | Usually improves during recovery. |
| Bleeding and infection | Possible risks of any major surgery. |
| Blood clots | A small risk after surgery. |
| Anaesthesia reactions | Possible side effects or complications. |
| Reduced kidney function | Kidney function decreases after donation because only one kidney remains. |
Life After Donation: What Changes and What Doesn't
Giving a kidney does not mean living a restricted life. Most donors can return to work, exercise, and other normal activities after recovery, but they should still take their healthcare needs seriously.
Diet and Lifestyle Adjustments
Most donors do not need a special long-term diet simply because they have donated a kidney. A balanced diet, regular physical activity, healthy weight and avoiding smoking can support long-term health. It is also sensible to avoid unnecessary medicines or supplements that could affect kidney function.
Long-Term Follow-Up Care
Regular health checks can include blood pressure measurement, kidney function testing and urine testing. A person who decides to donate a kidney should therefore think beyond the surgery itself, as long-term follow-up is part of responsible donor care.
Financial and Emotional Support for Living Donors
Donation can affect work, travel, family responsibilities and finances during recovery. Discuss these practical issues before surgery so the donor has enough support in the weeks after the operation.
Potential donors should ask the transplant centre about the following points:
- Medical and follow up costs
- Travel and hotel expenses
- Time off from work
- Insurance coverage
- Financial aid available
- Counselling and emotional support services
Conclusion
Choosing to donate a kidney requires careful thought and a clear understanding of both the benefits and risks. A thorough medical assessment helps determine whether donation is appropriate, while long term follow up helps protect the donor's health after surgery. There is no universal age limit for kidney transplants that can replace an individual medical assessment, so anyone considering donation should speak directly with an authorised transplant centre.

Frequently Asked Questions (FAQ's)
Is it safe to live with one kidney after donation?
Most carefully selected kidney donors can live healthy lives with one remaining kidney. The remaining kidney usually increases its workload to compensate for the removed kidney. However, donation does reduce overall kidney function, so regular health checks remain important.
What tests are done before someone can donate a kidney?
The evaluation can include blood and urine tests, kidney function measurements, blood pressure checks, imaging, infection screening, cardiovascular assessment and compatibility testing. Psychological and social assessments are also part of the process.
Can a living donor's remaining kidney fail later in life?
It is possible, although the risk is low in carefully selected donors. The risk varies with factors such as age, blood pressure, kidney function and other health conditions. That is why donor assessment considers a person's long-term health rather than focusing only on whether they are fit for surgery.
Does donating a kidney affect life expectancy?
There is no indication that donating a kidney reduces a donor’s life expectancy. Donation has not been shown to reduce life expectancy; however, it does involve medical risks and a lifelong commitment to maintaining good health.
