Transplant surgery is a medical procedure that involves replacing a damaged or failing organ with a healthy one from a donor. Common organs that can be transplanted include the heart, kidneys, liver, and lungs. The goal of the surgery is to restore normal function and improve the patient's quality of life. Before the surgery, patients undergo thorough evaluations to determine their eligibility. After the transplant, they require lifelong follow-up care and medications to prevent organ rejection, where the body’s immune system attacks the new organ. Successful transplants can significantly extend and enhance the lives of recipients.
