A kidney transplant is a surgical procedure that replaces a failing or damaged kidney with a healthy one from a donor. This can be a living donor, such as a family member or friend, or a deceased donor. The new kidney helps restore normal kidney function, allowing the recipient to live a healthier life. 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 those with chronic kidney disease or kidney failure.
