@kathymiami having your lab results bounce around sure can be frustrating. Especially when we can’t identify reasons for the improvements or worse ones. My eGFR has bounced too, between 14 - 42 since 2016 when I started really paying attention to it. It is currently 36. I don’t track my creatinine as well as you do (since it figures in to the eGFR). I have protein in the urine, but it has been negligible for awhile now. I have anemia related to my kidney disease. In the past I’ve had to take iron supplements and even iron IV infusions. My iron is stable right now. I also recall experiences of being tired and light headed. The worst was associated with an episode of severe anemia. I think that was before I even knew I had kidney disease and was another unrelated condition. Still my nephrologist asks me if I am experiencing those symptoms (tiredness and lightheaded) when I have office visit follow ups. Could you mention those symptoms to your nephrologist at your next follow up?
