Hi guys,

I had a very pleasing 6 month review this week, however, I am concerned by my GFR, which is to do with the rate that the kidneys do their stuff!.

On my test results, it states that my GFR is 78, which is acceptable, as the normal range is >60.
On further investigation, I read that a normal rate is actually > 90 and that a reading between 60 and 90 is an indicator of "mild" kidney failure!!. :shock:

I also read that GFR naturally decreases with age.
I do a lo carb diet and the main theme of current advice states that the high protein content of a lo-carb diet does tax the kidneys to a degree, however for normal healthy kidneys, this is not an issue.

So :?:
as a 53 year old, T2, is a GFR of 78 acceptable?

Regards Steve.
 
I would have thought an eGFR of 78 in your circumstances was absolutely fine, provided it doesn't change significantly over time. You don't get on the transplant list until around 20 and dialysis doesn't start until 15, so you're way off those numbers. Further info on the specifics of CKD (Chronic Kidney Disease) available at /www.renal.org, click on the CKD link.
 
Steve,

On a low carb, higher protein diet you may well find your GFR slowly improving over time. This has been my experience, and that of others on a low carb diet.
The damage is done by elevated glucose and/or insulin levels and once these are sorted out, the kidney function can begin to restore itself. Mine is on the way up, not down, desite yeaars of previous abuse.

All the best,

Them's great links Graham!
The calculator I'd used before gave me a reasonable eGFR which I was happy enough with. Using the one you posted, I worked out my GFR from my clinic tests in 1999 (before I'd even heard of low-carb), and then my most recent one in May this year.
Bear in mind that GRF is expected to fall slowly as we age.
Well it turns out that my GFR 10 years ago was 89. Now, 10 years later and following a diet higher in protein which, according to some at least, compromises kidney function over time, my GFR is apparently 105!
You've made my day and I think I'll order a bigger turkey this Xmas. :D

All the best,

Hi Ferg,
Mine came out at 104 which for a 65 year old seems fine to me :D

Have you got room for another round the table at Xmas :?: you may need some help with the turkey :lol:

Cheers
Graham
 
Hah! 105! In your face 'ol timer! :lol:
Always room for another 'round the Xmas table, actually in the space once used for roast spuds 'n parsips. They're not invited again this year.
