Regular exercise with elevated creatinine is a normal physiological phenomenon. Creatinine is an indicator of kidney function, and elevated creatinine indicates abnormal kidney function. Creatinine is also a product of muscle metabolism, and all exercises that can lead to enhanced muscle metabolism may lead to elevated creatinine, such as the usual running, push-ups, swimming, sit-ups, etc. Therefore, it is not necessary to worry too much when creatinine is found to be elevated after exercise, as it is a normal physiological phenomenon. For patients with abnormal kidney function, it is still recommended to exercise, mainly to enhance the resistance of patients. But when choosing exercise, avoid choosing too strenuous exercises, such as push-ups, it is recommended to choose more moderate exercises, such as jogging, brisk walking, swimming and so on. In addition, if you usually eat more lean meat, which is equivalent to the intake of exogenous creatinine will also increase, can also lead to the increase of creatinine, which is a normal physiological phenomenon.
