Peritoneal dialysis (PD) is a treatment that uses the lining of your abdomen (belly area), called your peritoneum, and a cleaning solution called dialysate to clean your blood. Dialysate absorbs waste and fluid from your blood, using your peritoneum as a filter. One benefit of PD is that it is not done in a dialysis center. You can do your PD treatments any place that is clean and dry. This can allow you more freedom to work, travel or do other activities you enjoy without worrying about scheduling dialysis appointments.
