Many diseases can damage the kidneys so that waste isn’t properly removed from your body.
When this happens, the waste builds up in your body. Over time, your health will seriously deteriorate (get worse).
If the damage becomes very bad, your kidneys don’t recover.
Without treatment, you will live as long as your kidneys can support you. The length of time that your kidneys continue to support you can depend on other medical conditions.
This is called end-stage kidney disease.
One option that is appropriate for some people with end-stage kidney disease is a kidney transplant from either a live or deceased donor.
