I am a 43 yo woman with no major health issues other than a hiatal hernia and acid reflux - plus GED (generalized anxiety disorder).
My mother is diabetic and my father pre-diabetic but all my diabetes tests are fine so far.
On last year's physical (July 2015) I found that my eGFR dropped to a 77 from 98 the previous year. Dr was not at all worried bc. it is still considered within normal range, very good blood pressure and no diabetes.
So she said several things can contribute to fluctuations in e-GFR including dehydration or some medicine/supplements, etc. Kidneys are fine as far as she's concerned. She did not want to repeat the test and said we'll take a look again next year.
I said OK but I waited 3 months (Nov 2015) and went to AnyLab test on my own to re-do the Metabolic Panel. This time I had more water in the morning, and the GFR came out at 86. A bit better but it still indicated a drop of over 10 in only one year. I also did a urine test for protein which came out negative (all good).
This year on the annual physical dr. ordered the metabolic panel again and the GFR came out at 75. Even lower than last year.
I think I was indeed dehydrated as I was fasting with no water since the evening before. I had also recently started weight lifting and a bit more vigorous exercise, as well as some supplements/herbs.
Dr. is still completely NOT worried and said "no kidney problems".
She tried to explain the drop with dehydration and age.
But really...In 2012 (at 40 yo) it was 104, in 2014 - 98, in 2015 - 77 and in 2016 - 75. This is too fast a drop to be attributed to aging only.
I insisted to see a nephrologist so she put in a referral even though she doesn't think I need to see one.
If these two values in the 70's were correct, something must have happened to my kidneys to experience such a major loss of renal function in only one year. This is supposed to be a value for a woman in her 70's, not early 40's.
Then again, I am thinking that I did experience a rise to 86 after the 77 value...but I am not sure which is closer to reality? The 70's or the 86?
At this age I probably should be somewhere in the mid- to upper 90's - for someone with no kidney issues whatsoever, as my dr. says - but now lower.
Every time I went to my physical I was indeed dehydrated because I was fasting to ensure all blood test come out accurate - and in fasting I also included "water fasting". This may have been a stupid idea.
Do you think e-GFR-s can fluctuate even by 20 points due to dehydration, recent supplements or weight lifting?
I tried to lift a bit more vigorously, indeed - but I am nowhere close to muscular or a major athlete (in fact quite a bit flabby). What about stress - as I HAVE gone through an unusually stressful period lately.
Thank you so much for any information or words of encouragement you might have for me and I apologize if this seems a bit on the frivolous side to people who are actually diagnosed with kidney disease.
I am just a major basket case when it comes to health issues and I sometimes wonder how much longer will my "frantic prevention" approach work?

Highly anxious about abrupt GFR drop
