There is no “best and fastest” way to reduce creatinine, you need to identify the cause of creatinine elevation, and then choose the appropriate way to reduce creatinine, the cause of creatinine elevation may be pathological or physiological factors. 1. Pathological factors: including pre-renal, renal, post-renal and other factors, such as massive loss of body fluids, acute glomerulonephritis, prostatic hyperplasia leading to urinary retention, etc. Many factors may lead to renal insufficiency, resulting in persistent creatinine increase, and specific treatment options are completely different, such as rehydration, diuresis, transurethral resection of the prostate and even dialysis, etc. Therefore, there is no such thing as a “pathological” method to lower creatinine. Therefore, there is no “best and fastest” way to reduce creatinine, and many diseases can not be cured only by “eating”, but also combined with intravenous drugs, dialysis, surgery and other means of treatment. 2. Physiological factors: Occasionally a physical examination found that creatinine elevation may be caused by physiological factors, such as eating more high-protein foods, strenuous exercise, fever, etc. At this time, creatinine elevation is temporary, you can adjust the diet, choose low-salt, low-fat and low-protein diets, eat more vegetables and fruits, and timely recheck. If the creatinine is elevated, it is recommended to consult the doctor in the regular hospital in time, and actively treat it.
