Creatinine 120μmol/L belongs to stage 1-2 kidney disease. Elevated creatinine indicates renal failure. renal failure can be divided into 4 stages according to the previous division. stage 1 belongs to the compensated stage of renal failure, with creatinine below 133 μmol/L. stage 2 is the decompensated stage of renal failure, with creatinine between 133 and 221 μmol/L. stage 3 is the decompensated stage of renal failure, with creatinine between 221 and 442 μmol/L. stage 4 is the renal failure Uremic phase, with creatinine above 442μmol/L. From here, we can see that creatinine 120μmol/L belongs to stage 1 of renal failure. The current common chronic kidney disease staging is 5 stages, according to the glomerular filtration rate staging, creatinine 120μmol/L is estimated to be in stage 1-2. Patients with stage 1-2 renal failure are mainly given conservative treatment, such as applying uremic pellets, Haikun Renxi capsules or medicinal charcoal tablets to detoxify the kidney, and if there is anemia, erythropoietin needs to be applied to correct the anemia. In addition, the application of amlodipine these antihypertensive drugs to control blood pressure, the main thing is to treat the underlying disease, such as blood sugar, blood pressure and so on.
