Frequently Asked Questions

18. What is kidney failure?

When your kidneys fail, they are no longer able to filter blood and remove waste from your body well enough to maintain health. Kidney failure causes harmful waste and excess fluid to build up in your body. Your blood pressure may rise, and your hands and feet may swell. Since the kidneys are not working well, the goal is to find treatments that can replace kidney function in order to maintain health. There are two main options for this: dialysis and transplantation.
