Dialysis, used in end stage kidney disease (also referred to as kidney failure, chronic kidney disease, and renal failure), it is a process where a machine filters the blood since the kidneys are no longer able to.[3] In addition to the inability to filter blood, kidney failure results in the body’s inability to make some vitamins and minerals (example: vitamin D), as well as difficulty excreting excessive amounts of certain vitamins and minerals (example: phosphorus).
