There are 2 main types of dialysis—hemodialysis (HD) and peritoneal dialysis (PD)—and each has different advantages, requirements and scheduling options. Depending on your health, lifestyle and other factors, you and your doctor should decide which type of dialysis is right for you.
Hemodialysis
The word hemo means “blood” and dialysis means “filter.” Simply put, hemodialysis is a process where blood is filtered outside the body by a machine called a dialyzer or “artificial kidney,” and then returned to your body.
Peritoneal dialysis
Peritoneal dialysis gets its name from the lining of your abdomen, which is called the peritoneum. This lining is a membrane that surrounds the space in your abdomen called the peritoneal cavity. This natural lining can be used to filter your blood.
