What Does an eGFR of 60 Mean?
If your recent blood test came back showing an eGFR of 60, you’re probably staring at that number wondering whether you should panic, relax, or call your doctor right now. You’re not alone — eGFR results in the 60s are one of the most common reasons people search for answers about their kidney health, and the truth is, the meaning of this number depends heavily on your individual context.
This guide breaks down exactly what an eGFR of 60 means, why it matters, what might be causing it, and what steps make sense next — written in plain language, without unnecessary alarm or false reassurance.
What Is eGFR, Exactly?
eGFR stands for estimated Glomerular Filtration Rate. It’s a calculation — not a direct measurement — that estimates how well your kidneys are filtering waste and excess fluid out of your blood. Your kidneys contain millions of tiny filtering units called nephrons, and each nephron has a structure called a glomerulus that does the actual filtering work.
Rather than measuring filtration directly (which would require an invasive test), doctors calculate eGFR using a simple blood test that measures creatinine, a waste product created by normal muscle activity. That creatinine level is then plugged into a formula along with your age, sex, and sometimes race or body size, to estimate how many milliliters of blood your kidneys filter per minute.
The result is expressed as mL/min/1.73m² — though most lab reports and doctors simply refer to it as a plain number, like “60.”
Is an eGFR of 60 Normal or a Problem?
This is where things get nuanced, and it’s the most important thing to understand about this number.
An eGFR of 60 sits right at the boundary between “normal” and “mildly reduced” kidney function, according to the staging system used by nephrologists and organizations like the National Kidney Foundation.
Here’s how eGFR ranges are generally categorized:
- 90 and above — Normal kidney function (assuming no other signs of kidney damage)
- 60–89 — Mildly reduced kidney function
- 45–59 — Mild to moderate reduction
- 30–44 — Moderate to severe reduction
- 15–29 — Severely reduced function
- Below 15 — Kidney failure
An eGFR of 60 technically falls into the Stage 2 Chronic Kidney Disease (CKD) range if it’s accompanied by other markers of kidney damage — such as protein in the urine, structural abnormalities, or genetic kidney disease. However, if there’s no other evidence of kidney damage, an eGFR of 60 on its own is often simply a sign of natural aging or a temporary fluctuation, not necessarily a diagnosis of kidney disease.
This distinction matters enormously. A 70-year-old with an eGFR of 60 and no protein in their urine may have perfectly normal kidney function for their age. A 30-year-old with the same number, plus protein in the urine, may be showing early signs of a kidney condition that deserves closer monitoring.
Why Context Matters More Than the Number Alone
Doctors don’t look at eGFR in isolation. They consider it alongside several other factors:
1. Your Age
Kidney function naturally declines with age, even in people without any kidney disease. It’s common for filtration rate to drop gradually starting in a person’s 40s or 50s, continuing through later decades of life. An eGFR of 60 in a 75-year-old is viewed very differently than the same number in a 35-year-old.
2. Urine Albumin or Protein Levels
A urine test called the urine albumin-to-creatinine ratio (UACR) checks for protein leaking into the urine — a key sign of kidney damage. If your eGFR is 60 and your UACR is normal, your kidney health is likely stable. If protein is present, your doctor may want to monitor things more closely or investigate further.
3. Trends Over Time
A single eGFR reading is a snapshot, not a trend line. What matters most to nephrologists is whether the number stays stable, improves, or declines over repeated tests taken weeks or months apart. A one-time reading of 60 that returns to 75 on a repeat test may simply reflect dehydration, a recent illness, or lab variability.
4. Underlying Health Conditions
Conditions such as diabetes, high blood pressure, autoimmune diseases, and recurrent kidney infections can all affect kidney filtration and are typically factored into how a doctor interprets your results.
5. Medications and Recent Activities
Certain medications (including some pain relievers, blood pressure medications, and antibiotics), high-protein diets, intense exercise shortly before testing, and dehydration can all temporarily lower eGFR readings without reflecting true kidney damage.
Common Causes of a Reduced eGFR
If your eGFR has dropped to around 60, several things could be responsible, ranging from harmless to more significant:
- Normal aging — a gradual and expected decline in filtration capacity
- Dehydration at the time of testing
- Diabetes, which is one of the leading causes of chronic kidney disease worldwide
- High blood pressure, which can damage the small blood vessels in the kidneys over time
- Recent illness or infection, which can temporarily affect kidney function
- Certain medications, especially long-term use of NSAIDs like ibuprofen
- A single functioning kidney, whether from birth or after donation or surgery
- Early-stage chronic kidney disease, particularly if paired with other risk factors
Because so many of these causes are temporary or manageable, an eGFR of 60 is rarely a medical emergency. It is, however, a signal worth paying attention to.
Symptoms You Might (or Might Not) Notice
One of the trickiest aspects of kidney function decline is that it’s often silent in its earlier stages. Many people with an eGFR around 60 feel completely normal and have no symptoms at all. This is precisely why routine blood work — even when you feel fine — plays such an important role in catching kidney changes early.
If symptoms do appear at this stage, they tend to be mild and nonspecific, such as:
- Slight fatigue
- Mild swelling in the ankles or feet
- Changes in urination frequency
- Difficulty concentrating
These symptoms are common to many conditions, so they shouldn’t be used to self-diagnose kidney issues — but they are worth mentioning to your doctor if they arise alongside a lower eGFR reading.
What Should You Do Next?
If your eGFR came back at 60, here’s a sensible, non-alarming path forward:
- Repeat the test. A single reading isn’t enough to draw conclusions. Ask your doctor about retesting in 3 months to check for stability or change, per standard clinical practice.
- Ask for a urine albumin test (UACR). This complements the eGFR and gives a fuller picture of kidney health.
- Review your medications with your doctor or pharmacist, especially if you regularly use NSAIDs or other drugs that affect kidney function.
- Manage blood pressure and blood sugar. These are the two most modifiable risk factors for kidney health, and keeping them well controlled can meaningfully slow or prevent further decline.
- Stay hydrated, particularly before blood tests, since dehydration can temporarily skew results.
- Consider a referral to a nephrologist if your eGFR remains at 60 or lower over repeated tests, or if you have additional risk factors like diabetes, high blood pressure, or a family history of kidney disease.
Lifestyle Habits That Support Kidney Health
Regardless of what’s causing an eGFR of 60, these habits are broadly protective for kidney function and overall health:
- Moderate protein intake — avoiding excessive protein, especially from processed sources, reduces strain on the kidneys
- Limiting sodium — supports healthy blood pressure, which protects kidney blood vessels
- Staying well hydrated — supports consistent, accurate kidney filtration
- Avoiding unnecessary NSAID use — for pain relief, alternatives like acetaminophen are often gentler on the kidneys when used as directed
- Regular physical activity — supports blood pressure and blood sugar control
- Routine checkups — especially important for anyone with diabetes, high blood pressure, or a family history of kidney disease
The Bottom Line
An eGFR of 60 is a number that sits right on the edge — it can represent a completely normal part of aging, a temporary dip caused by dehydration or illness, or an early marker of chronic kidney disease depending on your full clinical picture. It is not, by itself, a diagnosis, and it’s rarely cause for panic.
What it is, though, is useful information — a nudge to look a little closer, retest if needed, and address the factors within your control, like blood pressure, blood sugar, hydration, and medication use. Kidney health is best protected through early awareness and small, consistent habits, not last-minute intervention.
If you have an eGFR of 60 and questions about what it means for you specifically, the most reliable next step is a conversation with your doctor or a nephrologist, who can interpret the number in light of your full health history.
Frequently Asked Questions
Is an eGFR of 60 considered kidney disease? Not necessarily. It only counts as Stage 2 Chronic Kidney Disease if there’s also evidence of kidney damage, such as protein in the urine. Without that, it may simply reflect normal aging or a temporary factor.
Can eGFR go back up after being 60? Yes. If the drop was caused by dehydration, a temporary illness, or certain medications, eGFR can return to a higher level once the underlying cause resolves.
At what eGFR should I see a nephrologist? Many primary care doctors refer patients to a nephrologist when eGFR falls to 45 or below, or sooner if there are additional risk factors, protein in the urine, or a rapidly declining trend.
Does diet really affect eGFR? Diet can influence the factors that damage kidneys over time, such as blood pressure and blood sugar, and very high protein intake can put extra strain on kidney filtration. However, diet alone typically doesn’t reverse significant kidney damage.
Is 60 a bad eGFR for a 65-year-old? Not necessarily. Kidney function naturally declines with age, and an eGFR of 60 in someone in their 60s or older, without protein in the urine or other risk factors, is often considered within a normal range for that age group.
