In a healthy human body, kidneys are responsible for purifying the blood. As long as the kidneys perform this task well, there is no need for a patient to use dialysis treatment.
Due to reasons such as kidney failure and certain medical conditions (damaged kidneys and other diseases), kidneys become unable to carry out this purification process. This is when the dialysis process comes in handy!
When natural purification of blood (by kidneys) stops, it becomes necessary to intervene and perform artificial purification.
