Dialysis Treatment Options


Dialysis Treatment Options

Dialysis is a treatment that removes excess fluid and waste from your body when your own kidneys aren’t able to do their job effectively. In the last stage of chronic kidney disease, your kidneys have lost about 85% to 90% of their function. People who develop end-stage kidney failure need dialysis or kidney transplantation to live. 


What Does Dialysis Do?

Dialysis doesn’t “fix” the kidneys. It works like a kidney outside the body to remove wastes and fluids from the blood. Dialysis helps keep the body in balance by doing the job of healthy kidneys. It is important to find the dialysis treatment that is right for you, based on your physical, emotional, and lifestyle needs.

Hemodialysis

Hemodialysis uses an artificial kidney (hemodialyzer) to clean your blood outside of the body. It filters excess fluid and waste from your blood. To get blood from your body into the artificial kidney, the doctor makes an access (or entrance) into your

      FAQs About Hemodialysis

      Where is hemodialysis done?

      Dialysis can be done 

      • In a hospital 
      • In a dialysis center
      • In other medical facilities 
      • At home 

      You and your doctor will decide which place is best, based on your medical condition and your wishes. 

      How much time do hemodialysis treatments take?

      At a dialysis center, hemodialysis is typically done 3 times per week. Each treatment lasts about 3 to 5 hours. 

      At home, people do their hemodialysis treatments about 4 to 7 days per week. Each treatment lasts about 3 to 4 hours. 

      Is it possible to no longer need dialysis?

      If your kidney disease was caused by sudden or acute kidney injury, you may need dialysis for only a short time until your kidneys get better. 

      Patients who receive a kidney transplant no longer need dialysis for as long as their new kidney is working effectively. 

      Do I need a special diet?

      People on hemodialysis typically need to eat more protein and limit potassium, phosphorous, sodium, and fluid in their diet. People who have diabetes or high blood pressure may need other changes to their diet as well. Be sure to talk to your dietician or provider about the type of diet you need. 

      Is home dialysis better?

      Some research suggests that home dialysis is linked to 

      • Better results and health outcome because dialysis is done more often 
      • Improvement in some of the symptoms that dialysis patients often have, such as cramping, nausea, trouble sleeping, and loss of energy 
      • Better quality of life and ability to keep doing many of your normal activities 

      Peritoneal Dialysis

      Peritoneal dialysis (PD) cleans blood inside your body. The inside lining of your abdomen (peritoneal cavity) acts as a natural filter and is called the peritoneum, or peritoneal membrane. Before PD treatment, a catheter is placed into the peritoneal cavi

          How peritoneal dialysis works

          PD is carried out through a catheter placed in the peritoneum, which is located in your abdomen. This is where you exchange old solution for new solution. The 3 main steps in fluid exchange for PD are drain, fill, and dwell.
