Dialysis: Your Options, Explained
How dialysis steps in for failing kidneys, the two main types, and how you choose.
Last updated: 2026-09-24
Dialysis does some of the work your failing kidneys can no longer do — removing waste, salt and extra fluid from your blood. You usually need it when your kidney function drops below about 15%.
Two ways to dialyse
- Hemodialysis — your blood is cleaned by a machine, usually at a centre two to three times a week
- Peritoneal dialysis — your blood is cleaned inside your body using the lining of your abdomen, often at home
How you choose
This is a medical decision, not just a preference. It depends on your remaining kidney function, your abdomen’s suitability, your vascular access, your home situation and your own priorities. Many people switch between the two over time.
Dialysis keeps you well, but it doesn’t cure kidney failure. Many people on dialysis go on to have a transplant, which usually offers a better long-term outlook.
Frequently asked questions
How long can you live on dialysis?
Many people live for years on dialysis with good control of blood pressure, anaemia and diet. A transplant remains the best long-term option.
Can I keep working?
Often yes. Home peritoneal dialysis and evening sessions can help you keep a normal routine.
