What is Stage 3 CKD?

Moderate Kidney Damage with Reduced Function

Stage 3 chronic kidney disease is a more advanced stage in which kidney function is moderately reduced, with an estimated glomerular filtration rate (eGFR) between 30 and 59. At this point, the kidneys are not filtering waste and excess fluids as efficiently as before. This stage is often when symptoms may begin to appear, although some people may still feel relatively well. Early recognition and careful management during Stage 3 are essential, as kidney function can decline more rapidly without appropriate care.

Slowing progression is possible

Managing Stage 3 CKD

Preventing further damage through proactive care.

Managing Stage 3 CKD requires a more proactive and structured approach. Treatment typically focuses on controlling underlying conditions such as high blood pressure, diabetes, and heart disease, all of which can place added strain on the kidneys. Your healthcare provider may adjust medications, recommend dietary changes, and schedule more frequent follow-ups. With consistent care, many people are able to slow disease progression and maintain stability for an extended period of time.

Recognize the symptoms

Symptoms of Stage 3 CKD

Be alert to signs of kidney decline.

At Stage 3 CKD, some people may begin to notice symptoms related to reduced kidney function. These can include ongoing fatigue, swelling in the feet, ankles, or legs, changes in urination patterns, shortness of breath, or rising blood pressure. Symptoms may develop gradually and vary from person to person. Reporting new or worsening symptoms to your healthcare provider allows for timely evaluation and helps reduce the risk of complications.

Lifestyle matters

Dietary and Lifestyle Changes

Supporting kidney function with the right choices.

Lifestyle and dietary adjustments become especially important during Stage 3 CKD. A kidney-friendly diet may involve limiting sodium to control blood pressure, moderating protein intake to reduce kidney workload, and managing phosphorus and potassium levels as advised by your healthcare provider. Regular physical activity, maintaining a healthy weight, managing stress, and avoiding smoking or excessive alcohol can all support kidney and overall health.

Close monitoring

The Importance of Regular Monitoring

Frequent tests to track kidney function.

Close and consistent monitoring is a key part of managing Stage 3 CKD. Regular blood and urine tests, including eGFR measurements, help track how well the kidneys are functioning over time. Blood pressure checks and medication reviews are also important at this stage. These assessments enable your healthcare provider to adjust treatment as needed, address potential complications early, and reduce the risk of progression to more advanced stages of kidney disease.
