Peritoneal dialysis – A gentle approach that works around the clock, using your body’s own natural membrane
Your abdominal lining does the work
The peritoneum — a thin, smooth lining inside your belly — acts as a natural filter. It’s rich in tiny blood vessels, making it perfect for this purpose.
A cleansing fluid is introduced
A special fluid (called dialysate) flows through a small, permanent tube into the belly.
It sits there for a few hours (dwell time) while waste products and excess water pass across the membrane into it.
The used fluid drains out
After the dwell time, the fluid — now carrying the waste and extra water — drains out and is replaced with fresh fluid.
This cycle runs continuously, keeping you in balance.
You stay at home
A small machine can run overnight while you sleep (automated PD), or you do exchanges yourself during the day.
Most people manage this independently after a short period of training.
