Actress and singer Selena Gomez recently posted to her Instagram account that she received a kidney transplant because of her lupus; the transplanted kidney was donated to her by a close friend. For people facing kidney failure, transplantation of a healthy kidney from a living donor often presents a much better option than the alternative of dialysis. According to the Beth Israel Deaconess Medical Center, dialysis can only replace 10 percent of the work performed by a functioning kidney. On average, patients who received kidney transplants lived longer than those who remained on dialysis. The kidney donor also does not face significantly increased health risks from donating a kidney. There are the expected risks of going through a major surgery, as well as some increased risk of kidney failure, but there is no evidence that donating a kidney decreases life expectancy.
