Can a blood creatinine of 500 μmol/L heal itself?

Blood creatinine 500μmol/L suggests that it enters the renal failure stage, which is more difficult to be cured, including acute renal failure and chronic renal failure.
1. Acute renal failure: it is a clinical syndrome caused by various etiological factors resulting in short-term renal function injury, which can be seen in the increase of blood creatinine. The cause should be recognized as early as possible, and timely intervention measures should be taken to avoid further damage to the kidneys, which can be partially cured after active treatment, but it is more difficult to be cured by oneself.
2. Chronic renal failure: it is the common outcome of all kinds of chronic kidney diseases developing to the end stage. It is characterized by water-electrolyte balance imbalance and systemic dysfunction. Treatment is based on treating the primary disease and controlling the development of the disease. Usually, it cannot be cured by itself, and the only way to restore kidney function is through successful kidney transplantation.
If there is an increase in blood creatinine, you should go to the hospital in time and take treatment under the guidance of the doctor.
