@mimi234 I want to qualify my previous post and say that a sudden drop should be investigated. And of course your doctor can monitor you and explain things.

Technically an eGFR under 60 is called "stage 3 kidney disease" but my primary care doctor never even mentioned it (I saw it in my portal) and I did not get referred to a nephrologist until I suddenly dropped to 36. I think a lot of us "over 29" have eGFR's in the 50's.

I don't hydrate enough!
