Dialysis is a mechanical process that performs the work that healthy kidneys would do: It clears wastes and extra fluid from the body and restores the proper balance of chemicals (electrolytes) in the blood. Dialysis is needed when chronic kidney disease becomes so severe that the kidneys are no longer working properly. Follow the links below to find WebMD's comprehensive coverage about dialysis, how dialysis works as a treatment, the different kinds of dialysis, and much more.
