Nocturnal dialysis is a slower, longer hemodialysis treatment that takes place at night while you sleep. It takes 6-8 hours per night and three or more times per week. This procedure can take place at home or in a dialysis center. 




There are two ways to have nocturnal dialysis:

  1. In center nocturnal dialysis: It requires you to sleep at the dialysis center overnight. Special nurses and technicians who are skilled in doing hemodialysis manage the treatment.
  2. Nocturnal home hemodialysis: Having  nocturnal dialysis at home, increases the relaxation and comfort of nighttime treatments. Before having nocturnal dialysis at home, the patient and the nurse have to get trained so that the medical team can be assured that procedures can be followed.


You can ask your doctor or primary nurse whether home or in center nocturnal hemodialysis is better for you. It is recommended that list all your questions about nocturnal dialysis before your doctor appointment.

What are the advantages of nocturnal dialysis?

According to a study on dialysis centers around the world the best treatment outcomes were in France, where patients are hemodialyzed for eight hours, three days a week.  It can be said that “The longer treatment lasts, the better the results.”.


Health Benefits

  • You can see improved dialysis results in nocturnal dialysis.
  • Nocturnal hemodialysis actually helps alleviate sleep apnea and increase restorative sleep in many patients. These benefits can continue even on the dialysis off-nights.
  • It lowers your blood pressure and cramping and improves your cardiac function.
  • One of the biggest pluses of nocturnal dialysis is that it lets many patients decrease the medications they need to take. For example, the longer sessions remove more phosphorus than conventional dialysis. So, many patients can lower the number of phosphate binders they have to take, and some are able to completely discontinue the medications. Further, lower phosphorus levels contribute to better long term bone health.
  • It helps to improve sexual performance.


A Better Quality of Life

  • Dialyzing at night while sleeping leaves more time for daily routines.  It ensures patients live a more normal life working, playing with their kids, hanging out with friends-on the same schedule as everyone else.
  • Patients in nocturnal units feel more “in control of their lives.” 
  • Patients experience less depression and are better able to socialize. 
  • Nocturnal hemodialysis even has a positive effect on patients’ financial health. Patients have fewer concurrent illnesses, so they need less hospitalization. One study estimated that six times per week nocturnal dialysis patients needed 64 percent fewer hospital days. In addition, their need for fewer medications accounts for still further cost-savings.
  • Most people on nocturnal dialysis say they feel better and have a better appetite.
