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. When chronic kidney disease becomes so severe that your kidneys are no longer working properly, you may need dialysis. You may use dialysis to replace the work of the kidneys for many years.
