3. Grizzwald Chapman
Known as Grizz on the hit show 30 Rock, Grizzwald Chapman suffers from severe hypertension. In 2010, the disorder worsened considerably, causing his kidneys to fail. As a result, Chapman needed to have a kidney transplant and underwent dialysis prior to the surgery.
Without a kidney transplant, those who suffer kidney failure have no choice but to undergo dialysis. There are two variations of the procedure, but both are meant to remove the toxins from your body when the kidneys are no longer capable of doing it themselves. It is possible to maintain this treatment for a couple of months or years before finding a donor, but it is not meant to be a long-term solution; it is harsh on the body.
