Hello: Julie Chitwood @billchitwood

I am kidney transplant recipient ( my wife donated her kidney .. for which I am eternally grateful)
here are some of info I can share with you based on my experiences prior to the kidney transplant.

CKD= Five stages of chronic kidney disease
Stage 1 with normal or high GFR (GFR > 90 mL/min)
Stage 2 Mild CKD (GFR = 60-89 mL/min)
Stage 3A Moderate CKD (GFR = 45-59 mL/min)
Stage 3B Moderate CKD (GFR = 30-44 mL/min)
Stage 4 Severe CKD (GFR = 15-29 mL/min)
Stage 5 End Stage CKD (GFR <15 mL/min)

Yes as my kidney function deteriorated over time - I did become anemic too, figured that out why it happened after the kidney transplant - basically kidney plays an important role in the red blood cell creation cycle, the kidney signals the bone marrow to produce RBC and as the kidney function reduces the signal gets weaker (is my understanding) and hence less RBC are generated leading to anemia.

I had Stage 3B around in my 50s and had my transplant @ 70, A good nephrologist can help you navigate this CKD journey.

Also Low or high BP is not desirable if one experiences Kidney GFR issues, low BP reduces the perfusion function in the kidney where as high blood pressure destroys the nephron filters of the kidney
