The cause of repeated rise and fall of blood creatinine may be physiological or pathological, the former is caused by strenuous exercise, and the latter is caused by diabetes, chronic nephritis, urinary tract obstruction and so on.
Physiological causes of repeated rise and fall of blood creatinine is usually due to excessive consumption of meat or strenuous activities, which leads to fluctuations in blood creatinine, usually within the normal range, without special treatment.
Pathological causes such as diabetes, chronic nephritis, infection, urinary tract obstruction, dehydration and so on will lead to repeated rise and fall of blood creatinine, usually due to renal insufficiency.
Therefore, when blood creatinine fluctuates repeatedly, we should consult nephrology department in time to find out the causes of abnormal renal function and correct the factors leading to renal impairment, so as to avoid the continuous deterioration of renal function, which may progress to chronic renal failure or even uremia.
