A safe eGFR level is generally considered to be more than 90 in adults, although eGFR naturally declines with age, even without kidney disease.
Understanding eGFR
eGFR, or estimated Glomerular Filtration Rate, is a measure of how well your kidneys are filtering waste from your blood. A higher eGFR indicates better kidney function.
Normal eGFR Ranges
| eGFR Level | Interpretation |
|---|---|
| 90 or greater | Normal kidney function |
| Below 90 | Possibly reduced kidney function; further investigation may be needed |
Factors Affecting eGFR
- Age: As we age, it’s normal for eGFR to decrease, even in the absence of kidney disease.
- Health conditions: Diseases like diabetes, high blood pressure, and heart disease can affect kidney function and lead to a reduced eGFR.
- Medications: Certain medications can impact kidney function.
- Lifestyle: Factors such as smoking, diet, and lack of exercise can also affect your kidneys.
What If Your eGFR is Below 90?
If your eGFR is below 90, it does not automatically mean you have kidney disease. It warrants further investigation by your healthcare provider to understand the cause and determine if treatment or lifestyle changes are necessary.
Practical Insights
- Regular check-ups, including eGFR testing, are crucial for monitoring kidney health.
- Lifestyle choices, such as maintaining a healthy weight, blood pressure, and blood sugar levels, can help protect kidney function.
- It’s important to discuss any concerning symptoms or medical history with your doctor.
In summary, while an eGFR of more than 90 is generally considered normal for adults, individual results should be assessed within the context of a person’s age, overall health, and any other existing conditions.
