Understanding a Rising GFR in Stage 3a CKD: A Positive Sign of Stability and Improvement

In the context of chronic kidney disease (CKD), a rising Glomerular Filtration Rate (GFR) can be a reassuring sign. Typically, in CKD, GFR declines over time, making a rise a positive indicator of stable or slightly improved kidney function. For more insights, refer to my Quora profile!

What Does a Rising GFR Mean?

A rising GFR in the context of CKD can be encouraging. In CKD, GFR usually declines as the disease progresses. A rise in GFR, especially from a GFR of 54 and 57 last year to 59 this year, indicates a potential stabilization or mild improvement in your kidney function.

Factors Contributing to a Rising GFR

Several factors can contribute to a rising GFR, including:

Changes in Treatment: If you've made lifestyle changes or started new medications, these may improve your kidney function. Hydration Status: Fluctuations in hydration can affect GFR readings. Diet and Nutrition: A diet that supports kidney health may also contribute to improved GFR. Management of Underlying Conditions: Effectively managing conditions like diabetes or hypertension can have a positive impact on kidney function.

Why Not Overread GFR Values?

Small day-to-day fluctuations in GFR readings (up or down by 10 percent in your case, 5 points) can be misleading. There are several reasons for these fluctuations. These include:

Creatinine Lab Variations: Different labs can give varying results from day to day, often within a 5 to 10 percent range. Medications and Blood Pressure Changes: Medications and changes in blood pressure can affect GFR readings.

It's important to discuss these fluctuations with your healthcare provider. They can provide personalized insights based on your overall health and treatment plan.

Steps to Protect Kidney Function in Stage 3a CKD

At stage 3a CKD, the chance of kidney failure is low, but proactive steps can help preserve the kidney function you have left. Here are some steps to consider:

Better Hydration: Ensure you stay properly hydrated. Management of Blood Sugar and Blood Pressure: Effectively manage your blood sugar and blood pressure to protect your kidneys. Dietary Changes: Reduce soda intake and NSAID medications, and focus on a plant-based diet with less red meat. Exercise: Regular physical activity can support kidney health.

These lifestyle modifications can help stabilize GFR and potentially lead to better results in future GFR tests.

Conclusion

A rising GFR, especially in the context of CKD, can be a positive sign. However, it's crucial to maintain regular monitoring and follow-ups with your healthcare provider. Small fluctuations are common, and significant changes should be discussed with a medical professional. By taking proactive steps to protect your kidney function, you can improve your overall health and well-being.
