Chronic kidney disease affects over 10% of South Africans, often going undetected until advanced stages. While a dialysis recommendation can feel overwhelming, it is a vital step toward reclaiming your health and quality of life.
This guide simplifies medical jargon to explain the four primary types of dialysis. Our goal is to provide the clarity needed for confident discussions with your Advanced Renal Care team.
What is Dialysis and Why is it Necessary?
Before we explore the different types, let’s establish what dialysis does. Your kidneys are organs that work around the clock to filter waste products and excess fluid from your blood. When they can no longer perform this function effectively (a condition known as end-stage renal disease or ESRD), these toxins build up to dangerous levels.
Dialysis is a medical procedure that artificially performs the function of your kidneys. It’s not a cure for kidney disease, but it is a life-sustaining treatment that cleans your blood, allowing you to feel better and live longer.
The Four Main Types of Dialysis Explained
Choosing a dialysis method is a significant decision made in partnership with your nephrologist, balancing your medical needs with your lifestyle. Here is a breakdown of the four primary options:
- In-Centre Hemodialysis (IHD): The most common form, where you visit a clinic three times a week for approximately four-hour sessions. A machine filters your blood through an artificial kidney (dialyser). This is ideal for those who prefer professional medical supervision and a social environment.
- Home Hemodialysis (HHD): Using the same process as IHD, this version allows you to perform treatments at home after specialized training. It offers greater flexibility, with options for shorter, more frequent sessions or overnight treatment, leading to better health outcomes and fewer dietary restrictions.
- Peritoneal Dialysis (PD): This needle-free method uses the lining of your abdomen (peritoneum) as a natural filter. A permanent catheter allows cleansing fluid to enter and drain from your abdomen. It can be done manually throughout the day (CAPD) or automatically while you sleep (APD), offering maximum independence.
- Continuous Renal Replacement Therapy (CRRT): A specialized, 24-hour continuous treatment used exclusively for critically ill patients in the ICU. It is a gentle, life-sustaining measure for those too unstable for standard hemodialysis and is not an outpatient option.
Comparing Your Dialysis Options: A Quick Guide
Choosing a treatment method is about balancing medical needs with your personal lifestyle. Here’s a simple comparison based on key factors:
- Location: In-centre hemodialysis is the only option that requires you to travel to a clinic for every treatment. HHD and PD offer the freedom of being at home.
- Medical Supervision: IHD provides direct, on-site supervision by nurses and technicians. For HHD and PD, you manage your own care with 24/7 on-call support from your medical team.
- Schedule Flexibility: PD and HHD are the clear winners for flexibility, allowing you to integrate treatment around your life. IHD has a fixed, rigid schedule.
- Independence: If maintaining a high degree of independence is your priority, PD and HHD empower you to take an active role in managing your own health.

FAQs
Is dialysis painful?
The dialysis process itself is not painful. For hemodialysis, there is a prick when the needles are inserted into your access point, but this discomfort is brief. For peritoneal dialysis, there are no needles involved in the regular treatment, only the initial surgery to place the catheter.
How long do you have to be on dialysis?
For most people with end-stage renal disease, dialysis is a lifelong treatment. It performs the function of your kidneys but does not cure the underlying disease. The only alternative that stops the need for dialysis is a successful kidney transplant.
Can you work while on dialysis?
Absolutely. Many people on dialysis continue to work, study, and lead active lives. The flexibility of home hemodialysis and peritoneal dialysis (especially APD, which is done overnight) makes it easier to maintain a regular work schedule. Even with in-centre dialysis, clinics often offer different shifts to accommodate work.
What can you eat on dialysis?
Your diet is a very important part of your treatment. Most dialysis patients need to limit their intake of sodium, potassium, and phosphorus. You will also need to monitor your fluid intake. A renal dietitian will work with you to create a personalised eating plan that is both healthy and enjoyable.
Who pays for dialysis in South Africa?
In South Africa, dialysis is covered as a Prescribed Minimum Benefit (PMB) by medical aid schemes. This means that if you are on a medical aid, your scheme is required to cover the costs of your treatment. For patients without medical aid, treatment is available through the public healthcare system, though access can sometimes be limited by resource availability.
