Whether a high blood creatinine without proteinuria is serious depends mainly on the cause of the elevation. If creatinine is elevated due to physiological reasons or acute kidney injury, creatinine may return to normal after removing the influencing factors, and it is usually not serious at this time. If the creatinine is elevated due to chronic kidney disease, with the progress of the disease, it may develop into uremia, which is relatively serious.
Some patients with elevated creatinine may be due to their own muscle content is higher, or usually eat more meat, exercise more caused by the routine urine and urinary system ultrasound and other related tests are not abnormal, clear kidney without obvious disease, this kind of situation is usually not serious.
If the patient due to various reasons for acute kidney injury creatinine elevation, correct the reversible causes, creatinine may return to normal, this is usually not serious; if chronic kidney disease caused by creatinine elevation, with the progress of the disease, may develop into uremia, this is relatively more serious.
If patients find high creatinine, it is recommended to go to regular hospitals in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
