Common complications of the different stages of kidney disease (1):
Stage 1 (GFR > 90 mL/min/1.73 m2 with other evidence of kidney damage) | in patients with stage 1 CKD - hypertension more frequent than amongst patients without CKD |
Stage 2 (GFR 60-89 mL/min/1.73 m2 ) with other evidence of kidney damage | hypertension frequent in patients with stage 2 CKD mild elevation of parathyroid hormone |
Stage 3 (GFR 30-59 mL/min/1.73 m2 ) | hypertension common decreased calcium absorption reduced phosphate excretion more marked elevation of parathyroid hormone altered lipoprotein metabolism reduced spontaneous protein intake renal anaemia left ventricular hypertrophy |
Stage 4 (GFR 15-29 mL/min/1.73 m2) | As above but more pronounced plus - metabolic acidosis hyperkalaemia decreased libido |
Stage 5 (GFR 0-14 mL/min/1.73 m2 ) | All the above (with greater severity) plus - salt and water retention causing apparent heart failure anorexia vomiting pruritus (itching without skin disease) |
