Dialysis is a treatment for kidney failure that helps filter waste products from the blood when the kidneys are not working properly. The two main types of dialysis are hemodialysis and peritoneal dialysis.
- Hemodialysis uses a man-made membrane (dialyzer) to filter wastes and remove extra fluid from the blood. It is usually done in a hospital or outpatient dialysis centre 3 times a week. Some types of hemodialysis are done at home.
- Peritoneal dialysis uses the lining of the abdomen (peritoneal membrane) and a solution (dialysate) to remove wastes and extra fluid from the body. Treatment can be done at home over several sessions each day or for several hours at night.
