Glomerular Filtration Rate (GFR) measures how well your kidneys filter waste. A higher GFR is better, but it naturally declines with age.
🔹 Normal GFR by Age
| Age | Normal GFR (mL/min/1.73 m²) |
|---|---|
| 20–29 years | 90–120 (Optimal) |
| 30–39 years | 85–115 |
| 40–49 years | 80–110 |
| 50–59 years | 75–105 |
| 60–69 years | 70–100 |
| 70+ years | 60–90 |
💡 For your age (47 years), a GFR of 80–110 is considered normal.
🚨 A GFR below 60 for more than 3 months may indicate chronic kidney disease (CKD).
🔹 What If Your GFR Is Low?
✔ Stay hydrated and eat a kidney-friendly diet.
✔ Control blood pressure & blood sugar (leading causes of CKD).
✔ Avoid NSAIDs (ibuprofen, naproxen) & high-protein diets.
✔ Use herbs like nettle leaf, punarnava, and dandelion to support kidney function.
✔ Get regular kidney function tests to monitor changes.
🔹 Conclusion
- Your target GFR (47 years old) should be around 80–110 mL/min.
- A GFR above 60 is generally fine unless there are symptoms of kidney disease.
- If your GFR is low, lifestyle changes can help improve or stabilize it.
