Chronic dialysis is a long-term therapy for kidney failure. It takes over part of the work your kidneys can no longer do. It filters waste, balances salts, and removes extra fluid. Some people stay on dialysis for years. Others use it while waiting for a transplant. Treatment can happen in a clinic or at home. If you are comparing options at dialysis centres in Johannesburg, you will see both routes. Your kidney team will tailor a plan around your health, routine, and goals. The goal is steady health and a life you can manage. This guide sets out what dialysis is, who might need it, the types, the main risks, and how life fits around treatment.
What chronic dialysis does
Dialysis is not a cure. It replaces key kidney functions to protect your health. It can ease swelling, nausea, and foggy thinking. It helps control blood pressure and fluid. Many people feel more energy once they are on a stable plan.
Types of chronic dialysis
You and your team will choose a method that fits your health and lifestyle. Both main types work well when done correctly. (nhs.uk)
Haemodialysis
Haemodialysis uses a machine to clean your blood. Blood flows to a dialyser, gets filtered, then returns to you. In a clinic, sessions are on fixed days. At home, training allows a more flexible schedule. Access is usually a fistula in the arm. A graft or catheter may be used if needed.
Peritoneal dialysis
Peritoneal dialysis uses the lining of your abdomen as a natural filter. A soft tube in your tummy allows cleansing fluid in and out. Some people do manual exchanges during the day. Others connect to a small machine at night while they sleep.
When treatment starts
Dialysis usually starts when symptoms and test trends show it is no longer safe to wait. The decision is not based on a single number. Teams look at the whole picture, such as uremic symptoms, fluid overload, blood pressure, and quality of life. This approach is supported by international guidance. (KDIGO)
Daily life on dialysis
You will follow a set routine. In clinic, expect several sessions each week. At home, you may dialyse more often with shorter sessions. You will track weight and blood pressure. Your team adjusts your prescription as your needs change. Work, study, and travel are possible with planning. Supplies and guest sessions can be arranged in advance.
Side effects and risks
Most people do well with a tailored plan. Some effects can happen. Tell your team so they can adjust treatment.
- Low blood pressure with cramps or dizziness
- Tiredness after sessions
- Itchy skin or restless legs
- Infection risk at the access site
- Weight or fluid gains between sessions that need control
Getting started
You will receive education and a plan for access. That may be fistula surgery for haemodialysis, or a catheter for peritoneal dialysis. Training covers infection prevention, fluid limits, and medicines. Ask about home support, transport, after-hours contacts, and travel options. In large cities, including dialysis centres in Johannesburg, you can compare in-centre times, home programmes, and support services.
FAQs
How do I choose between haemodialysis and peritoneal dialysis?
Both clean the blood well. The choice depends on your health, lifestyle, home setup, and comfort with self-care. Your team will guide you through training, risks, and support. (nhs.uk)
Can I travel while on dialysis?
Yes. In-centre patients can book guest sessions. Peritoneal dialysis patients can ship supplies ahead. Plan early and get letters and prescriptions ready.
Will I still need dialysis after a transplant?
A successful transplant often replaces dialysis. Some people may need dialysis again in the future. Your team will explain the pathway and monitoring schedule. (KDIGO)
Chronic dialysis is a partnership between you and your kidney team. The aim is steady health and a routine you can live with. The right start time is based on how you feel and how your results change, not one lab value. Both haemodialysis and peritoneal dialysis can work well. Diet, fluid control, and good access care help you feel better. You can still plan work and travel with a bit of organisation. If a transplant suits you later, dialysis can bridge you to surgery. Keep your questions ready, set clear goals, and review your plan often with your team.
