Kidney Transplant
Human beings are normally born with two kidneys but can survive with one kidney. Kidney donors can survive after donating a kidney, but they do put themselves at risk of complications.

Close relative
- Many patients choose to have a kidney transplant, which often comes from a close relative. Close relatives have a higher chance of being a tissue match.

Other registered donor
- Kidneys can also be transplanted from people who have recently died, provided that they are a tissue match and have registered onto the organ donor register.

Immunosuppressants
- Patients receiving a donor kidney often have to take immunosuppressant drugs for the rest of their lives.
- These drugs suppress the immune system to prevent it from attempting to destroy the foreign cells of the transplanted kidney.
