Staying up late generally does not lead to elevated blood creatinine, but it may lead to elevated blood creatinine if the patient has underlying renal disease.
Elevated blood creatinine is divided into physiologic and pathologic. Physiological cases include strenuous exercise, consuming large amount of meat, etc., which will usually return to normal after resting and controlling the diet; pathological cases include diabetic nephropathy and glomerulonephritis.
Staying up all night does not usually lead to elevated blood creatinine, and staying up all night may lead to hormone metabolism disorders, acne, etc. Most of them will not damage kidney function. However, if the patient himself has kidney disease, such as glomerulonephritis, pyelonephritis, etc., staying up all night may aggravate the condition, which may lead to elevated blood creatinine.
If you find high blood creatinine, you should go to the hospital in time to find out the cause and treat under the guidance of professional physicians.
