Fatigue/dizzy: The numbers above appear normal, you cite the creatinine as 56 or is that 0.56 because the estimated GFR is ok. Causes for fatigue/dizziness: smoking,diet, perimenopause, no exercise, thyroid, anemia, low B12, B6, low magnesium. For dizziness also consider sinusitis, allergies, otitis, low blood pressure when initially standing up,vertigo,less likely carotids, vascular ,tumors,autoimmune
