A kidney transplant is a surgical procedure that replaces a failing or damaged kidney with a healthy one from a donor. The donor can be living or deceased, and the new kidney helps restore normal kidney function, which is essential for filtering waste and excess fluids from the blood. Before the transplant, patients undergo evaluations to ensure they are suitable candidates. After the surgery, they need to take medications to prevent their body from rejecting the new kidney. Successful transplants can significantly improve the quality of life for individuals with kidney disease or kidney failure.
