Third, they have better control of blood pressure levels and less anemia. Fourth, they can put insulin in the peritoneal cavity with the dialysate. Insulin taken this way better controls blood glucose. The major problem with CAPD is infection, which can occur in the abdomen or at the catheter. A person using CAPD must keep the catheter area clean and follow all procedures carefully.
Some people get lower back problems and weak abdominal wall muscles or a hernia.
CAPD is not for everyone. A person must see well and have good motor skills. CCPD is similar to CAPD in that the exchange of dialysate and blood is done in the abdominal cavity. The difference is that in CCPD, the exchange is done automatically by a machine called a cycler. A cycler delivers the dialys-ate and drains it.
