What is high creatinine urine?

High urine creatinine can be seen in normal physiological phenomena. Creatinine is a metabolite of protein. If you eat more protein foods, such as seafood, animal viscera or beef, you will cause increased creatinine production, so urine creatinine will rise accordingly, but generally blood creatinine is in the normal range. Urinary creatinine elevation can also be seen in patients with disease, more common in kidney disease, due to kidney disease caused by kidney filtration function decline, resulting in reduced water excretion in the body, so the performance of creatinine concentration in the blood, urine creatinine concentration will also rise.
