Hemodialysis vs. Peritoneal Dialysis: Pros and Cons / Hemodialysis vs. Peritoneal Dialysis:
About 14% of Americans have chronic kidney disease (CKD), according to the National Institute of Diabetes and Digestive and Kidney Diseases. This means their kidneys are not working properly.
What is Dialysis?
Dialysis is a treatment that filters waste from the blood. It helps when kidneys fail to do their job.
Types of Dialysis
There are two main types of dialysis: hemodialysis and peritoneal dialysis. Each type works differently and has different benefits.
Choosing the Right Dialysis
You should discuss with your doctor whether hemodialysis or peritoneal dialysis is better for you. Your doctor will guide you in making the best choice for your situation.
Hemodialysis vs. Peritoneal Dialysis:
Hemodialysis is a type of dialysis that cleans the blood using a machine. This machine is called an artificial kidney or dialyzer.
How Does Hemodialysis Work?
During hemodialysis, blood flows from an access point in the arm into the dialyzer. The machine filters the blood through a membrane, removing waste products.
The Dialysis Process
The filtered waste products are washed away with a fluid called dialysate. Cleaned blood is then returned to the body.
Treatment Schedule and Options
Hemodialysis treatments usually occur three times a week and last about four hours each. Some patients may also choose home hemodialysis for more convenience.
What is Peritoneal Dialysis?
Peritoneal dialysis is another type of dialysis that removes waste products from the blood when your kidneys are not functioning properly. The biggest difference in hemodialysis vs peritoneal dialysis is that hemodialysis requires an artificial kidney machine to filter blood while peritoneal dialysis does not. Rather than using a machine, peritoneal dialysis uses the lining on the inside of the belly as a natural filter for blood.
During peritoneal dialysis, the dialysate flows through a catheter into part of the abdomen. The peritoneum, which is the lining of your abdomen, acts as a natural filter and removes the waste products from your blood. After a set “dwelling” time, the fluid containing the filtered waste products flows out through the catheter so it can be safely discarded.
This type of dialysis is a good option for patients that meet certain health requirements and want fewer restrictions than they’d have with hemodialysis. However, this type of dialysis is not ideal for all patients. There are two types of peritoneal dialysis: continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis.

With CAPD, the abdomen is filled with dialysate. The patient allows it to stay for a set dwell time before draining.
How CAPD Works?
Gravity moves the dialysate through the catheter without the need for a machine. The process relies on gravity rather than mechanical assistance.
Treatment Schedule and Flexibility
According to the National Kidney Foundation, patients typically need three to five exchanges during the day. Additionally, they require one exchange with a longer dwell time while sleeping.
Performing Exchanges
Exchanges can be done in any clean and sanitized location. Patients can continue their usual activities while the dialysate is in their abdomen.
Prevalence of Chronic Kidney Disease (CKD)
According to the National Institute of Diabetes and Digestive and Kidney Diseases, about 14% of Americans have CKD. This indicates a significant portion of the population is affected.
What is Dialysis?
Dialysis is a treatment designed to filter waste products from the blood. It is used when kidneys cannot perform their function properly.
Types of Dialysis
There are two main types of dialysis: hemodialysis and peritoneal dialysis. Each has different methods and benefits.
Choosing the Right Dialysis
It’s important to discuss with your doctor whether hemodialysis or peritoneal dialysis is better for you. Your doctor will help determine the best option based on your condition.
Hemodialysis vs Peritoneal Dialysis
When comparing hemodialysis and peritoneal dialysis, consider which is best for you. Peritoneal dialysis offers continuous filtration and less disruption to daily life. On the other hand, hemodialysis is better for patients with more severe kidney function loss.
Factors Affecting Your Choice
Peritoneal dialysis may not be suitable for obese patients or those with abdominal scarring. Hemodialysis is often preferred for patients who want professionals to handle more treatments.
Key Considerations
Only you and your doctor can decide the best type of dialysis. Factors to consider include your kidney function, overall health, home situation, lifestyle, and personal preferences.
