What Is Dialysis?
Who needs dialysis
When a person with chronic kidney disease (CKD) reaches end stage renal disease (ESRD), also known as kidney failure or stage 5 kidney disease, the kidneys are no longer functioning to filter and clean the blood the way healthy kidneys normally would. Without treatment, life-threatening waste and toxins will build up in the body. At this point, dialysis treatment or a kidney transplant is needed to prolong life.
Doctors use a number of kidney function tests when determining kidney health. Early diagnosis of CKD and regular monitoring can help you keep kidney function for as long as possible—and allow you and your doctor to plan for ESRD treatment when necessary.
EXPLORE TREATMENT OPTIONS
There are several treatment options when kidney failure occurs at stage 5 CKD. Discuss all the choices with your doctor to determine what’s right for you.
How does dialysis work?

What are the 2 types of dialysis?
Hemodialysis and peritoneal dialysis are the 2 main kinds of dialysis. Both types of dialysis filter unwanted waste from your bloodstream. Depending on which type of dialysis you choose, you may also have options for treating in a center or at home.
Hemodialysis
Hemodialysis filters your blood through a dialysis machine. Once you are connected to the machine via your hemodialysis access, blood flows into the machine, gets filtered and is returned to your body. There is a choice in where you do hemodialysis and who performs the treatment. In-center hemodialysis is performed by a trained team of nurses and technicians. At-home hemodialysis can be performed in the comfort of your own home, either with the help of a care partner or on your own. See how hemodialysis machines work.
Peritoneal dialysis
Peritoneal dialysis uses the blood vessels in the lining of your abdomen—the body's natural filter—along with a solution called dialysate to filter blood via a peritoneal catheter. With this method, blood never leaves your body. Peritoneal dialysis can be done with a machine or manually at home, at work or even while traveling. See how peritoneal dialysis machines work.
Dialysis treatment is prescribed by your doctor. Together, you and your doctor will discuss treatment options and determine what's right for you. If you decide to go on dialysis, your doctor will prescribe your treatment time and frequency based on your unique health needs. It's important to complete your dialysis treatment exactly as prescribed to feel your best.
