What are the Types of Peritoneal Dialysis

Peritoneal dialysis is a process by which you remove waste products and extra fluids from your blood. If we had to be asked what’s peritoneal dialysis, the answer would be when the body’s own peritoneal cavity is used to clear the blood. The peritoneal cavity is a space in your abdomen. So, in peritoneal dialysis blood is cleaned from inside and not outside your body. Peritoneal dialysis is considered as an advantage over hemodialysis by many people.

Peritoneal dialysis is to be done every day, seven days a week for the dialysis patient. This fact of PD to be done daily is seen as one of the good virtues of it as there is minimal buildup of salt, water, and waste products in the body due to peritoneal dialysis.

In this blog we will detail out the two main types of peritoneal dialysis:

  • CAPD
  • APD


CAPD is an acronym for Continuous Ambulatory Peritoneal Dialysis. The steps of dialysis involve in this process are as follows:

  • In this type, the catheter for peritoneal dialysis is connected to a special tube that is designed to allow two to three quarts of cleansing fluid known as dialysate to flow into the peritoneal cavity in the abdomen. The whole process of filling your abdomen with the dialysate takes 10-15 minutes
  • Once the abdomen is filled with dialysate, the catheter is capped to prevent any leak
  • The lining of the abdomen also known as the peritoneum acts as a natural filter between the dialysate and blood. It lets the wasteful toxins and extra fluid in the blood pass into the dialysate while acting as a barrier for the important components of the blood.
  • The dialysate is kept in the abdomen for a few hours depending upon evaluation by the doctors for you on the basis of your body type. This time period is known as dwell time
  • After the dwell time, the dirty dialysate is drained into a waste bag from your body via the other ends of the catheter.
  • This waste bag is then discharges
  • The same process is repeated three to four times a day. Every new process starts with the draining of old dialysate and filling up of new dialysate. This is known as exchanges in CAPD

The biggest advantage of CAPD is that it can be done at any place and at any given time as it cleans your blood while it is inside your body


APD stands for automated peritoneal dialysis. This is a type of peritoneal dialysis in which a machine called cycler does the job of performing exchanges for you while you are asleep. The catheter for peritoneal dialysis is connected to the cycler at the night in this type. This means that you would not be doing the exchanges during the day instead the draining and fill up of dialysate will be done automatically. Except for the above mentioned difference APD and CAPD are same.

Of the two types of peritoneal dialysis, the one suitable for you will depend upon your lifestyle and also your preference. One might also switch from one type of PD to another if the first one will seem not suitable

Effects on peritoneal dialysis on your normal life

  • If PD is the type of dialysis you choose for yourself, you will be taught certain new things related to the procedure. This will include:

    • What supplies do you need to order
    • How to prevent infections
  • Your monthly schedule will certainly include a checkup from a health care team to monitor your lab results, medicines etc.
  • It is important to know that PD is an efficient method to remove waste from your body but it can’t take place of the normal functionality of your kidneys. That is why, to make it more efficient, you’ll need t take medicines.
  • Restrictions in the food you eat is an obvious effect of dialysis but with PD your will be restricted less in diet in comparison to hemodialysis
  • It is necessary to keep your blood pressure in control


It is completely necessary to understand that even after choosing any one of the types of peritoneal dialysis; you can still be evaluated for hemodialysis or even transplant. Kidney failure is not something for there is a linear treatment. Many people experience the need of different treatment while going through kidney failure and then throughout their life.
