How to distinguish the symptoms of the renal insufficiency in the different stages?

Kidney disease stage: You need to see a nephrologist to get a 24 hour urine for creatinine clearance and protein. This will give you your renal function and put you into a stage of chronic kidney disease (ckd). You may feel no symptoms until stage 5 CKD where you may have some anorexia or reversal of day-night sleeping patterns. Patients with CKD in stages 3-4 may have anemia and with high parathyroid hormone levels.
