Dialysis is commonly administered to treat patients who suffer from kidney failure. The medical procedure, typically involving the use of a special machine, maintains a patient's vital signs by taking over the essential functions of the kidneys, as stated by WebMD.
Dialysis is categorized into two types: hemodialysis and peritoneal dialysis. A patient undergoing hemodialysis is connected to a dialysis machine, which removes wastes and excess fluids while keeping the normal balance of minerals in the blood through a dialyzer. Peritoneal dialysis involves internal filtering of the blood via a specialized cleaning solution known as a dialystate. Although treatment received from dialysis may help restore the kidneys back to their normal state, people with chronic kidney failure have only two long-term options: dialysis or kidney transplantation, according to Healthline.
