What is Dialysis?

Dialysis is a treatment that does some of the things done by healthy kidneys. It is needed when your own kidneys can no longer take care of your body's needs.

What does Dialysis Do?

Like healthy kidneys, dialysis keeps your body in balance. Dialysis does the following:

  • removes waste, salt and extra water to prevent them from building up in the body
  • keeps a safe level of certain chemicals in your blood, such as potassium, sodium and bicarbonate
  • helps to control blood pressure

Can I get dialysis at home?

Yes. Dialysis can be done in a hospital, in a dialysis unit that is not part of a hospital, or at home.

What is hemodialysis?

Hemodialysis is dialysis of the blood, esp. with an artificial kidney, for the removal of waste products. Minor surgery is involved.

What is peritoneal dialysis and how does it work?

The removal of soluble substances and water from the body by transfer across the peritoneum, utilizing a solution which is intermittently introduced into and removed from the peritoneal cavity (which lines the abdominal cavity).

There are advantages and disadvantages with peritoneal dialysis. Some advantages are:

  • it can be done at home
  • steps are easy to learn
  • easy to travel with
  • fluid balance is easier to maintain

Disadvantages:

  • very invasive
    • infection is a concern
  • requires attention to cleanliness
