My eGFR was about 77 before12/23 norovirus (extreme dehydration, fever, BP spike) resulted in an eGFR of 56. I'm 71 and (was) very active; the eGFR dropped to 32-39 the next summer, enough to see a nephrologist. She said just stay hydrated, 8-9 glasses of water a day. Because 32-39 is stage 3b, I modified my diet to less protein and simple carbs, more fiber and complex carbs. My kidney biopsy last year just showed scarring of glomeri and tubes. I'm now on Jardiance 12.5 mg/d to "relax" my blood and kidney vessels and excrete excess salt and glucose. It is usually diagnosed for those with high BP, Type 2 diabetes, and/or heart disease (none of which I have). With it, my eGFR is 42 and my previous avg. resting BP of 120/70 is now 105/73. I don't know if the CKD is leaving me fatigued, or if the now lower BP is limiting how much O2 I can deliver to cells. My nephology NP just said maybe I will feel better next year. Does having state 3b CKD result in mild to moderate fatigue?
