Answer 1

Answer:

Peritoneal dialysis (PD) is a type of dialysis which uses the peritoneum in a person's abdomen as the membrane through which fluid and dissolved substances are exchanged with the blood.[1] It is used to remove excess fluid, correct electrolyte problems, and remove toxins in those with kidney failure.[2] Peritoneal dialysis has better outcomes than hemodialysis during the first couple of years.[3] Other benefits include greater flexibility and better tolerability in those with significant heart disease.[3]
