Chronic renal insufficiency can be categorized into 4 stages using blood creatinine as a criterion, chronic renal insufficiency compensated stage, decompensated stage, renal failure stage and uremia stage.
Chronic renal insufficiency compensated stage blood creatinine level in 133~177μmol/L, decompensated stage blood creatinine level in 178~442μmol/L, renal failure stage blood creatinine level in 451~707μmol/L, and uremia stage blood creatinine level ≥707μmol/L.
Patients with chronic renal insufficiency experience retention of metabolites, imbalance of water, electrolytes, and acid-base, causing systemic disorders in various systems. It often shows weakness, loss of appetite, bone pain, edema, proteinuria, oliguria or anuria.
Chronic renal insufficiency should go to the hospital in time and be treated under the guidance of professional physicians.
