Diabetic patients with blood creatinine 150μmol/L suggests that the creatinine is elevated, which may be caused by dietary factors, but also may be caused by diabetic nephropathy, acute renal insufficiency and other disease factors. Dietary factors can be recovered, while diabetic nephropathy is difficult to recover. 1. Dietary factors: eating a large amount of meat products in a short period of time can cause a temporary increase in creatinine, which can be normalized in such cases. 2. Disease factors: Diabetic nephropathy may also cause creatinine elevation, which suggests that the patient’s renal function is impaired, and it is difficult to recover. Acute renal insufficiency can also cause elevated creatinine. Patients with acute renal insufficiency who are treated in time may recover in the early stage, but if the treatment is not timely, it is difficult to recover. Diabetic patients with elevated creatinine are advised to go to the hospital and ask the doctor to make a judgment, and should not make a blind judgment on their own.
