Is this age-related decline in GFR or kidney disease?

All my labs are normal. My egfr was 47 then a month later 52 testing again in a few weeks. Bun creatine ratio normal. No high blood pressure or diabetes. Not sure what's goong on. Increased hydration and exercise. 67 year old who has exercises fay for over 20 years. Not sure what to think. Google had me anxious all the time

@aconsolmagno Welcome to Mayo Clinic Connect! Most of us will agree, looking at trends in our kidney function, rather than a specific test, is the better way to view things.

What could cause the differences from lab test to lab test? Possibilities include:
-A different lab processing the samples.
-An infection or illness you are getting over.
-Dehydration.
-Change in medications/timing of periodic medications in relation to the testing date.

And, many of us were cringing when you mentioned Google causing you anxiety! It's so easy to "go down a rabbit hole" on Google, and information you find is not always accurate, nor relatable to your situation!

Has your medical team offered any explanation for the differences in your eGFR?

No they have not. Just improving and retest. I guess I don't understand how egfr with only 3 variables works. I do a very intense hot yoga with 35 year Olds and instructors are surprised I keep up plus cardio every day and weights at least once a week so probably for a 67 year old I'm fit. I'm just wondering if that makes a difference and no one answers

After following doctors orders to drink way more water on a daily basis, avoid salt, avoid aspirin and avoid sodas, gfr is 62 and creatinine is 9.6. Waaaay better.

Consider not exercising for at least 2 days before a creatinine blood test because the proteins will be affected by muscle metabolism. Stay hydrated but not too much salt(s) as well. I'm 71 and used to avg 160 mi/week on my bikes, but diagnosed with stage 3a CKD last summer so ramping down (no known risks other than having covid)

I’m a healthy 68 yo female, consider myself active.
No health issues.
Last annual Dr visit in April….All my labs were normal (pretty much same values as the last 12 years or so) except eGFR of 49.
No known risk other than Covid as well.
Going in for repeat soon. And also renal ultrasound before that visit.

That's encouraging. That's exactly what I'm doing but it's so hard not to imagine worst case thanks

Thanks I will try that. Hiws it been adjusting to the new normal? I'm just wondering g what to expect

That sounds very much like me. Surprised at my egfr. I'm very confused that the only 3 variable is age sex and creatine and not anything else. Can't get much information from Dr so googling as been my downfall and causing anxiety

So far I am asymptomatic, other than loss of endurance and touch of fatigue due to covid. I can still do long fast walks and bike rides, just not as long as before and I make sure my hydration/electrolytes are good. Early stage 3a CKD isn't supposed to have many symptoms. Nephrologist says at this stage mostly drink 8 glasses of water or more a day. A lot of CKD is the fear of what is going to rise up and bite us next, doing everything right and still this happens. If CKD stays at this level, we are good, with 3b the restrictions with meat proteins, phosphorus, potassium, and other salts begins. I've already made changes to my diet; because I have celiac I'm already used to not eating stuff. Thankfully dark chocolate is good.
