What the kidneys do
The kidneys clean the blood. They remove waste and extra water. They also help to control blood pressure and to make red blood cells.
When the kidneys fail
Kidney failure means that the kidneys cannot do this work well enough. Waste and water then build up in the body. Without treatment, kidney failure is a danger to life.
What dialysis does
Dialysis does part of the work of the kidneys. It removes waste and extra water from the blood. It does not cure kidney failure.
The two main types
| Type | How it works | Where it happens |
|---|---|---|
| Haemodialysis (HD) | A machine cleans your blood through a filter. | Usually at a dialysis unit, a few times a week. |
| Peritoneal dialysis (PD) | A fluid in your belly takes up waste. You drain it and put in new fluid. | Usually at home, every day. |
Most patients in Kenya use haemodialysis. Few patients use peritoneal dialysis.
Who decides
Your kidney doctor (nephrologist) decides if you need dialysis. The doctor also decides which type suits you. Ask your renal team about every option, including a transplant.
