If the elevation of blood creatinine is caused by kidney disease, it is more serious; if it is caused by physiological conditions such as staying up late at night or eating a lot of meat food, it is generally not serious.
Blood creatinine generally refers to endogenous creatinine, which is mainly produced by the body’s muscle exercise metabolism, and then excreted in urine after glomerular filtration, so when creatinine is elevated, it may be due to the rise of muscle content, or kidney damage.
Generally, the muscle content of human body will not change suddenly, so when the creatinine value increases, we should consider the possibility of kidney injury, generally the normal reference value of male blood creatinine 53~106μmol/L; female reference value of 44~97μmol/L, creatinine elevation if it is caused by kidney injury, such as glomerulonephritis, hypertensive nephropathy and so on, generally more serious.
But at the same time can not be excluded physiological conditions such as late at night, muscular athletes, eat a lot of meat food, etc., at this time is generally not serious, no special treatment, regular review can be.
It is recommended that patients with abnormal blood creatinine should go to regular hospitals for kidney test in time, and if there is kidney damage, it should be treated in time.
