Stages of Chronic Kidney Disease (CKD)
Chronic kidney disease progresses through five stages, classified by the degree of kidney function remaining. Understanding which stage you are at helps determine the right monitoring plan, treatment approach, and when to prepare for more advanced interventions.
Early Stages of CKD
Chronic kidney disease usually shows no obvious signs or symptoms in its early stages. The body can generally compensate for a gradual reduction in kidney function — this is why a person can donate one kidney and still live a normal life, as the remaining kidney works harder to compensate.
However, regular health screening with blood and urine tests can detect potential kidney problems before symptoms appear. Early discovery allows for closer monitoring, dietary intervention, and medication to slow progression before irreversible damage occurs.
Late Stages of CKD
If kidney disease is not caught early, symptoms may begin to emerge — including blood or protein in the urine, increased urination frequency, muscle cramps, and poor appetite. By this point, kidney function has declined significantly.
The Glomerular Filtration Rate (GFR) is the primary measure used to assess how advanced kidney disease is. It estimates the percentage of kidney function remaining. Note that GFR alone is not sufficient to identify stages 1 and 2 — additional markers such as protein in the urine are also needed.
The 5 Stages of CKD
Kidney damage present (e.g. protein in urine) but GFR is normal or increased. No symptoms. Often detected only through routine screening. Early lifestyle and dietary intervention is most effective at this stage.
Mild reduction in kidney function. Usually no symptoms. Monitoring is important to track whether the condition is progressing. Risk factor management (blood pressure, blood sugar, diet) is the focus.
Moderate reduction in kidney function. Some patients begin to experience mild symptoms. Specialist nephrology review is generally recommended at this stage to guide management.
Moderate to significant reduction. Risk of complications rises. Most patients are referred to a nephrologist at this stage. Treatment to slow progression and manage complications becomes more intensive.
Severe reduction in kidney function. Symptoms are usually present. This is the stage at which planning for renal replacement therapy — dialysis or kidney transplantation — should begin, even if treatment has not yet started.
End-stage kidney failure. The kidneys can no longer sustain life without intervention. Dialysis or a kidney transplant is required. A transplant generally offers better long-term outcomes for eligible patients.
Early diagnosis and treatment are essential — especially for patients with diabetes. Diabetic patients should undergo a microalbuminuria test at least once a year to detect diabetic nephropathy early — the chronic loss of kidney function occurring in people with diabetes mellitus.
A Personalised Approach to CKD
Managing chronic kidney disease is rarely straightforward. Treatment varies significantly for each patient based on the stage of disease, medical history, current conditions, lifestyle, and diet. A personalised approach is essential.
