Living donors can donate one lung, but full lung donation is rare and requires strict medical criteria and compatibility.
The Reality of Lung Donation from Living Donors
Lung transplantation has saved thousands of lives worldwide, but the supply of donor lungs remains critically limited. Unlike kidneys or a portion of the liver, donating an entire lung from a living person is far more complex and rare. The human body depends heavily on both lungs for adequate oxygen exchange, making the risks and challenges of lung donation significant.
Living lung donation usually involves donating a single lobe rather than an entire lung. This procedure is called a lobar lung transplant. In some cases, two living donors each donate one lobe to replace both lungs in the recipient. This approach is complex but has been performed successfully in select medical centers.
The question “Can You Donate A Lung To Someone?” requires understanding these nuances: full lung donation from living donors is nearly impossible due to anatomical and physiological constraints. However, lobar donation offers a viable alternative, especially for pediatric patients or smaller adults who require smaller lung volumes.
Medical Criteria for Lung Donation from Living Donors
Strict medical screening ensures donor safety and recipient success. Potential living lung donors must meet rigorous criteria:
- Excellent pulmonary function: Donors must have near-perfect lung capacity and no history of respiratory disease.
- Overall good health: No chronic illnesses, infections, or conditions that could complicate surgery or recovery.
- Compatible blood type: Blood group compatibility between donor and recipient reduces rejection risks.
- Size match: Donor lobes must fit the recipient’s chest cavity to ensure proper function.
- No smoking history: Smoking damages lung tissue and disqualifies most donors.
These criteria are non-negotiable because the surgery carries substantial risk not only for the recipient but also for the donor. Removing part of a healthy lung affects breathing capacity and increases vulnerability to infections post-operation.
Surgical Procedure: Lobar Lung Transplantation
The surgical process involves removing one or more lobes (sections) of the donor’s lungs rather than an entire organ. The human right lung has three lobes; the left has two. Surgeons carefully extract these lobes while preserving as much healthy tissue as possible in the donor.
In recipients, these lobes replace diseased lungs or parts thereof. This method is particularly useful in children or small adults whose chest cavities cannot accommodate whole adult lungs.
The surgery can last several hours and requires general anesthesia with advanced monitoring. Postoperative care is critical to manage pain, prevent infection, and support breathing during recovery.
The Risks Involved in Donating a Lung or Lobe
Donating a portion of your lung isn’t without serious risks. Both short-term surgical complications and long-term health impacts exist:
- Pneumothorax (collapsed lung): A common risk after surgery where air leaks into the chest cavity.
- Respiratory infections: Reduced lung volume may increase susceptibility to pneumonia or bronchitis.
- Reduced exercise capacity: Donors often experience decreased stamina due to less overall lung function.
- Surgical complications: Bleeding, blood clots, or adverse reactions to anesthesia can occur.
- Pain and scarring: Thoracic surgery results in significant postoperative pain and permanent scars.
Despite these risks, many donors recover well with proper care and rehabilitation. Long-term studies show most return to normal activities within months but may need lifestyle adjustments.
Lung Function After Donation
After donating a lobe, the remaining lung tissue undergoes compensatory growth over time—meaning it expands slightly to improve function. However, total lung capacity never fully returns to pre-donation levels.
Studies indicate that donors typically lose about 20-30% of their total pulmonary function immediately after surgery but regain much of it within one year through rehabilitation exercises like breathing therapy.
This partial loss means donors should avoid high-risk activities that demand peak respiratory performance post-donation.
The Demand vs. Supply Challenge in Lung Transplantation
Lung diseases such as chronic obstructive pulmonary disease (COPD), cystic fibrosis, pulmonary fibrosis, and severe asthma often lead patients to require transplants when other treatments fail.
Unfortunately, donor lungs are scarce because:
- Lungs are highly sensitive organs prone to damage during brain death events.
- Lungs must be free from infection or injury at time of donation.
- Lungs from deceased donors deteriorate quickly after removal.
Living donor lobar transplantation helps bridge this gap slightly but cannot meet overall demand due to its complexity and limited donor pool.
Lung Donation Compared to Other Organs
Here’s how lungs stack up against other commonly donated organs:
| Organ | Living Donation Possible? | Main Challenges |
|---|---|---|
| Lung (whole) | No (only lobes) | Anatomical complexity; vital for breathing; limited regeneration |
| Liver (partial) | Yes | Surgical complexity; regeneration capability high |
| Kidney (whole) | Yes | Donor can survive with one kidney; lower surgical risk than lungs |
| Heart | No (deceased donors only) | No regenerative ability; critical organ function |
| Pancreas (partial) | Sporadically yes | Surgical complexity; metabolic impact on donor/recipient |
This table highlights why “Can You Donate A Lung To Someone?” is answered differently than other organ donations—lungs are unique in their structure and function.
The Ethics Behind Living Lung Donation
Because living donation carries risk without direct health benefit for the donor, ethical considerations are paramount:
- Informed consent: Donors must fully understand risks before agreeing.
- No coercion: Pressure from family or society invalidates voluntary consent.
- Psycho-social evaluation: Ensures mental preparedness for impact on lifestyle after donation.
- Recipient benefit vs. donor risk balance: Medical teams weigh potential outcomes carefully before approving procedures.
Hospitals employ multidisciplinary teams including surgeons, ethicists, psychologists, social workers, and coordinators to uphold these standards rigorously.
The Process From Evaluation To Surgery For Living Lung Donors
Becoming a living lung donor involves multiple steps designed to protect both parties:
- Candidacy referral: Recipient’s medical team identifies potential living donors among relatives or friends.
- Initial screening: Blood tests, chest X-rays, CT scans evaluate basic eligibility.
- Pulmonary function tests: Measure how well lungs work under various conditions.
- Psychological assessment: Determines mental readiness for donation experience.
- Surgical consultation: Detailed discussion about procedure risks and benefits with thoracic surgeons.
- Surgery scheduling: Coordinated timing between donor and recipient surgeries minimizes ischemic time (time organs remain without blood supply).
After surgery, both patients require intensive monitoring in specialized units before moving toward rehabilitation phases.

Frequently Asked Questions
Can You Donate A Lung To Someone as a Living Donor?
Yes, living donors can donate part of a lung, typically a single lobe, rather than an entire lung. Full lung donation from living donors is extremely rare due to the complexity and risks involved. Lobar lung transplants are a safer and more common alternative.
What Are the Medical Criteria to Donate a Lung to Someone?
Donors must have excellent lung function, no history of respiratory disease, good overall health, compatible blood type, appropriate size match, and no smoking history. These strict criteria ensure donor safety and increase the chances of transplant success for the recipient.
How Does Donating a Lung to Someone Affect the Donor’s Health?
Donating a lung lobe reduces breathing capacity and increases vulnerability to infections. The surgery carries significant risks, so only healthy individuals with strong pulmonary function are considered for donation to minimize complications and ensure recovery.
Is Full Lung Donation Possible from Living Donors?
Full lung donation from living donors is nearly impossible due to anatomical and physiological challenges. Instead, lobar lung transplantation—donating one or more lobes—is performed. This method helps recipients without severely compromising the donor’s respiratory health.
Who Typically Receives Lungs Donated by Living Donors?
Lobar lung transplants are often performed on pediatric patients or smaller adults who require smaller lung volumes. In some cases, two living donors each donate one lobe to replace both lungs in a recipient, making this complex procedure lifesaving in select situations.
Conclusion – Can You Donate A Lung To Someone?
The straightforward answer: donating an entire lung as a living person isn’t feasible due to physiological demands on both donor and recipient. However, you can donate a lobe—a portion of your lung—in select cases through living lobar transplantation programs designed with strict criteria ensuring safety for all involved.
This nuanced approach offers hope for patients awaiting transplant while highlighting how vital matching anatomy and health conditions are when considering “Can You Donate A Lung To Someone?” It’s a testament to modern medicine’s balance between pushing boundaries and protecting life at every step.
