Peritoneal Dialysis

The process of peritoneal dialysis

Peritoneal dialysis uses a natural filter inside your body-the lining of your belly, called the peritoneal membrane-to remove wastes and extra fluid from your body. It also works to restore the normal balance of certain minerals in the blood (electrolytes).

The dialysis fluid fills the belly and pulls out extra minerals and fluids from the bloodstream. These wastes then drain out of the body along with the dialysis fluid into a collection bag.

Peritoneal dialysis is usually done at home.
