Treatment of creatinine reduction: 1. Treatment for the cause. Common causes of elevated creatinine are primary glomerulonephritis, hypertensive nephropathy and diabetic nephropathy. For hypertensive nephropathy and diabetic nephropathy, we should actively regulate blood pressure and blood sugar to keep them within the normal range, which can achieve a certain creatinine lowering effect. 2, oral medication to lower creatinine. The reason why these drugs can lower creatinine is by increasing the number of human bowel movements so that creatinine is excreted from the feces. 3, oral adsorbents. For example, activated charcoal and the like can lower creatinine. Finally, hemodialysis and peritoneal dialysis can be used to achieve the creatinine lowering effect.
