What Is a Good Kidney Number? Understanding eGFR and Kidney Health

Learn what a good kidney number means, how eGFR measures kidney function, and why monitoring it is essential for kidney health.

A good kidney number refers to the estimated Glomerular Filtration Rate (eGFR), which measures kidney function. A normal eGFR ranges from 90 to 120 mL/min/1.73m². Values above 90 indicate healthy kidney function, whereas numbers below 60 for three months or more may suggest chronic kidney disease. It's crucial to monitor these values regularly, especially for those at risk.

FAQs & Answers

  1. What is considered a normal eGFR value? A normal estimated Glomerular Filtration Rate (eGFR) ranges from 90 to 120 mL/min/1.73m², indicating healthy kidney function.
  2. What does a low kidney number mean? A kidney number (eGFR) below 60 for three months or more may indicate chronic kidney disease and requires medical attention.
  3. How often should I check my kidney function? Regular monitoring of eGFR is recommended, especially for individuals at risk of kidney disease, such as those with diabetes or high blood pressure.
  4. Can lifestyle changes improve my eGFR? Yes, maintaining a healthy diet, staying hydrated, managing blood pressure, and avoiding nephrotoxic substances can help support kidney function.
