Living Partial Liver Donation
A Living Gift With the Power to Save a Life
Living partial liver donation allows a healthy person to give a portion of their liver to someone whose liver is failing. The liver's unique ability to regenerate makes this possible: after surgery, the donor's remaining liver and the transplanted portion grow until each can meet the body's needs. A living-donor transplant may shorten a patient's wait and allows surgery to be planned when the donor, recipient, and transplant teams are ready.
Donation may be directed to a relative, friend, acquaintance, or another specific person, or non-directed to someone the donor does not know. MatchingDonors.com helps potential living donors and patients find one another and offers access to specialists and mentors who understand the transplant journey. A qualified U.S. transplant center independently evaluates every donor, determines compatibility, approves donation, and performs the transplant.
How liver regeneration works
The liver has a remarkable ability to regenerate. After donation, liver cells in both the donor and recipient grow rapidly, and the liver usually returns close to an appropriate size within weeks to months. Regeneration means growth of functioning liver tissue; it does not mean that the removed lobe grows back in its original shape. During recovery, donors need follow-up testing and must follow their transplant team's guidance about medicines, alcohol, diet, lifting, work, and activity.
Donor evaluation and eligibility
Potential donors must be adults who can make an informed, voluntary decision and are healthy enough for major surgery. MatchingDonors.com requires potential donors using its service to be at least 21. Transplant programs set their own medical criteria, so an online profile or initial screening does not guarantee approval. Evaluation is designed to protect the donor first—not simply to make a transplant happen.
- Medical evaluation: health history, physical examination, blood and urine tests, liver-function testing, infection screening, and heart and lung assessment.
- Liver imaging: CT or MRI scans map the liver's size, blood vessels, and bile ducts. Some donors may also need a liver biopsy.
- Psychosocial evaluation: the team considers motivation, emotional readiness, support at home, financial concerns, and whether anyone is pressuring the donor.
- Independent support: an Independent Living Donor Advocate protects the donor's interests and helps the donor understand choices, risks, and rights.
Some medical or psychosocial conditions may make donation unsafe. A potential donor may pause or stop the process at any time, including after evaluation. The decision must remain free from pressure, and the donor's private medical information is protected.
How donor and recipient matching works
Matching involves more than willingness. The transplant center checks compatible blood types, donor and recipient body size, the amount and anatomy of liver tissue needed, and whether the recipient can safely receive the graft. Blood tests may include tissue typing and a crossmatch to assess immune compatibility. Unlike a kidney exchange, there is no single routine “swap” process for liver donation; the surgical team creates an individualized plan for each donor-recipient pair.
Surgery, recovery, and help at home
Donor and recipient operations are performed at a transplant hospital, usually at the same time. Surgeons remove the portion best suited to the recipient while preserving enough healthy liver for the donor. The exact operation depends on anatomy and recipient size. Donor surgery is major abdominal surgery and generally takes several hours.
A liver donor can expect a hospital stay of about five days, although every recovery is different. Many donors gradually return to normal activities in about eight to twelve weeks. Fatigue and discomfort are common early on, and return to driving, lifting, exercise, and work depends on healing and the type of job.
Before surgery, identify a dependable care partner and arrange transportation, meals, household help, dependent or pet care, and time away from work. Caregivers should understand wound care, medicines, activity limits, warning signs, and whom to call after hours. Donors need scheduled transplant-program follow-up and should continue routine medical care throughout life.
Risks, safety, and informed choice
Most living donors do well, but donation provides no medical benefit to the donor and carries real short- and long-term risks. These can include pain, bleeding, infection, blood clots, reactions to anesthesia, bile leakage or narrowing, hernia, bowel problems, injury to nearby organs, psychological distress, liver failure, need for another operation or transplant, and—rarely—death. Risks differ by the portion donated, surgical approach, donor health, and transplant center experience.
The transplant team should explain the donor's individualized risks, the program's outcomes, alternatives for the recipient, and what is known—and not known—about long-term effects. The decision must be voluntary. Donors may change their mind at any point, including after evaluation, without owing the recipient or MatchingDonors.com an explanation.
Costs and financial considerations
The recipient's insurance generally covers the donor's transplant-related evaluation, surgery, and hospital care, but coverage varies. Donors may still face travel and lodging expenses, lost wages, dependent care, routine health testing, treatment of an unrelated condition discovered during evaluation, or some long-term care. Donation can also affect access to or the cost of life, disability, or long-term-care insurance.
Before testing begins, ask the transplant center's financial coordinator exactly what is covered. Eligible U.S. donors may receive help with travel, lodging, lost wages, and dependent care through the National Living Donor Assistance Center; an application generally must be approved before surgery. Federal law prohibits buying or selling an organ or receiving anything of value in exchange for donation.
Support from MatchingDonors.com and your care team
Living liver donation affects potential donors, recipients, caregivers, and entire families. MatchingDonors.com offers more than a place to connect: our team can help people find compassionate support from healthcare professionals, kidney and transplant mentors, patients, family mentors, and legal or advocacy specialists.
- Healthcare professionals: speak with experienced physicians, specialists, nurses, healthcare professionals, or medical volunteers about general organ-transplant, diabetes, and dialysis questions.
- Transplant mentors: connect with experienced peer mentors who understand evaluation, transplantation, living donation, and the questions families often face.
- Patient and family mentors: hear from people with firsthand experience navigating transplant, donation, recovery, and caregiving.

These services complement the transplant center's donor coordinator, social worker, financial coordinator, pharmacist, mental-health professionals, and Independent Living Donor Advocate. Personal medical advice, eligibility, compatibility, surgery, and follow-up must come from the transplant center.
Emotional and family support
Hope, uncertainty, fear, relief, guilt, and disappointment can all be part of living donation. These feelings may affect donors, recipients, and caregivers differently—even when surgery goes well. Peer mentors can offer perspective and reassurance, while transplant social workers and mental-health professionals provide confidential clinical support.
Ask for help when stress begins to affect sleep, relationships, daily life, or the ability to follow medical care. Caregivers should share responsibilities, accept specific offers of help, and protect time for their own rest and healthcare. Seeking support is part of a safe transplant plan.
The donation process
- Learn and connect. Create a MatchingDonors.com donor profile, respond to a patient's story, or contact a living-donor transplant program.
- Complete an initial screening. A living-donor coordinator reviews basic health information and explains the program.
- Undergo evaluation. Medical, surgical, psychosocial, compatibility, and financial reviews protect both donor and recipient.
- Receive an independent decision. The transplant program decides whether donation can proceed safely; the donor separately decides whether to continue.
- Plan surgery. If approved and matched, both teams coordinate timing and prepare the donor and recipient.
- Recover and follow up. The donor attends required follow-up visits and returns to daily life gradually.
Common questions
Does the liver really grow back?
Both portions grow after transplant and usually reach a size that supports each person's needs. The liver regenerates functioning tissue, but not necessarily the exact original shape.
Do I need to be related to the recipient?
No. Donors may give to a relative, friend, acquaintance, or someone they do not know. The transplant center—not the relationship—determines medical suitability.
Can I live a normal life after donation?
Most donors return to active, healthy lives after recovery. Individual outcomes vary, and lifelong healthy habits, routine care, and transplant-center follow-up remain important.
Will I need anti-rejection medicine?
The donor generally does not need anti-rejection medicine because the remaining liver is their own. The recipient will need immunosuppressive medicine to reduce rejection risk.
What if I am not approved or change my mind?
Evaluation is designed to protect you, and not every willing person can donate safely. You can stop at any time. The transplant team will protect your privacy and can help communicate that donation will not proceed.
Does creating a MatchingDonors.com profile make me a donor?
No. A profile expresses interest and may help you connect. Donation happens only after a transplant center completes evaluation, confirms a safe match, obtains informed consent, and approves surgery.
What support is available to donors and families?
MatchingDonors.com can help people connect with healthcare professionals, transplant mentors, patient and family mentors, and legal or advocacy specialists. The transplant center also provides donor coordination, independent advocacy, social work, financial guidance, education, and clinical follow-up.
