They need to do a lot of research into kidney failure. People with kidney failure need to dialysis 3 x weekly, they are on fluid restriction as they do not urinate, they are given a diet chart so they know what they can and can’t eat as the dialysis can not remove all the potassium from foods. The patients do not look pale and sick they look dehydrated. A person with kidney failure can live up to 30 years on dialysis. Other than that the show is entertaining
