I was diagnosed stage 3 CKD about 7 years ago. I brought my blood kidney numbers into normal range with nutrition, and my GFR fluctuates. The bloodwork before last it was normal, the last one was back down.The other day, I mentioned this to my opthalmologist and he said it was unusual to have low GFR and normal range for all other markers.
Can anyone tell me possible causes, please?
Thank you!
