腎絲球過濾率 eGFR
eGFR (Estimated Glomerular Filtration Rate)
*eGFR is a key indicator for assessing kidney filtration function. It estimates the volume of blood filtered by the glomeruli per minute (measured in mL/min/1.73㎡) based on serum creatinine, age, gender, and ethnicity.
*Normal Range
Healthy Adults: >60 mL/min/1.73㎡ (may be age-related).
eGFR naturally declines with age, but values below 60 usually indicate abnormal kidney function.
*Causes of eGFR Decline
-Chronic Kidney Disease (CKD):
Common causes include diabetes, hypertension, and glomerulonephritis.
-Acute Kidney Injury (AKI):
Triggered by infections, dehydration, or nephrotoxic drugs (e.g., NSAIDs, contrast agents).
-Aging:
eGFR naturally decreases with age but should be monitored if levels are too low.
-Other Factors:
Renal artery stenosis, hereditary kidney disorders (e.g., polycystic kidney disease).
*How to Protect Kidney Function
-Control Chronic Diseases:
Maintain stable blood sugar and blood pressure to reduce kidney burden.
-Stay Hydrated:
Drink adequate water to avoid dehydration and support normal filtration.
-Avoid Nephrotoxic Medications:
Minimize use of NSAIDs and other drugs harmful to kidneys.
-Adopt a Healthy Diet:
Follow a low-sodium, low-protein diet to ease kidney strain, and avoid high-sodium and high-phosphorus foods.
-Regular Monitoring:
High-risk individuals (e.g., those with diabetes, hypertension, or a family history of kidney disease) should regularly check eGFR and urine markers.
*Conclusion
eGFR is a core metric for evaluating kidney function and identifying risks of kidney decline early. By managing chronic conditions, adopting a healthy diet, and maintaining a balanced lifestyle, kidney function can be preserved effectively. If eGFR continues to decrease or falls below 60, seek medical advice for further evaluation and treatment.
