Final answer:
The major advantage of peritoneal dialysis is the ability for patients to conduct treatment at home with a less restrictive diet, offering greater convenience and a more normal lifestyle.
Step-by-step explanation:
One of the major advantages of peritoneal dialysis is that the diet is less restricted and dialysis can be performed at home. Unlike hemodialysis, which often requires patients to go to a dialysis center multiple times per week, peritoneal dialysis can be done in a patient's own home, providing greater convenience and flexibility. Additionally, dietary restrictions are typically less stringent for those undergoing peritoneal dialysis compared to hemodialysis, permitting a more normal lifestyle.
