Chronic Kidney Disease and Dialysis, Explained
The kidneys quietly clean the blood every day. When they fail gradually, early detection and the right treatment make a big difference.

What do the kidneys do?
The kidneys filter waste and extra fluid from the blood, balance salts and minerals, and help control blood pressure. In chronic kidney disease (CKD), this filtering ability declines slowly over months or years.
Why it often goes unnoticed
Early CKD usually causes no symptoms. As it advances, warning signs may appear.
- Swelling in the feet, ankles or around the eyes
- Tiredness, poor appetite or nausea
- Passing less urine, or frothy urine
- Difficult-to-control blood pressure
Main causes and risk factors
- Long-standing diabetes
- Uncontrolled high blood pressure
- Recurrent kidney infections or stones
- Overuse of certain painkillers
How CKD is managed
Early on, the focus is on controlling blood sugar and blood pressure, diet, and protecting remaining kidney function. Regular blood and urine tests track progress.
When kidney function becomes very low, dialysis takes over the job of filtering the blood, or a kidney transplant may be considered. A well-run dialysis unit keeps patients comfortable and stable for years.
