Understanding organ donation
Audience: patients-public, students-learners ยท Review state: published
What it is
Organ donation is giving an organ or tissue to help someone who needs a transplant. One deceased donor can save several lives - heart, lungs, liver, kidneys, pancreas, intestines - and improve many more through donated tissue such as corneas, skin, and bone.
Kidneys and parts of the liver can also be donated by living people, because the body manages with one kidney and the liver regrows.
The need
Far more people wait for transplants than organs become available, and many die waiting. Kidneys are the most needed organ by far; most people on waiting lists need one, and dialysis is only a partial substitute.
Donation rates vary widely between countries and communities, and every registered donor genuinely matters.
How deceased donation works
Deceased donation happens only after death is declared by doctors independent of the transplant team, most often after brain death with the body supported on a ventilator. The donor's medical care is never compromised to obtain organs - the teams are separate, and saving the patient's life comes first, always.
Families are consulted, and in most systems their support is sought even when the person had registered as a donor. Donation does not disfigure the body and does not prevent an open-casket funeral, and donors are not charged for the process.
Registering and living donation
Registering as a donor takes minutes through national registries or, in many places, a driving license or health card. Telling your family your wishes is the most important step, because they are the ones asked at a difficult moment.
Living donation, usually a kidney for a relative or friend, involves thorough medical and psychological evaluation to confirm the donor stays healthy. It is a major, voluntary decision with no payment involved - selling organs is illegal almost everywhere.
