What are the reasons for high urine creatinine?

If a casual physical examination reveals that your creatinine level is high, this is not enough to indicate that you have kidney disease. It is recommended that you relax and not put too much pressure on yourself. Even if the urine creatinine is detected to be high, other symptoms should be combined to judge the condition. The reasons for high urine creatinine may not be clear to everyone. Let's hear what the experts have to say.

A creatinine value that is higher than the normal value is called high creatinine. Creatinine includes blood creatinine and urine creatinine, but blood creatinine is a more meaningful measure of kidney function. Therefore, high creatinine generally refers to high blood creatinine.

The normal value of blood creatinine varies from hospital to hospital. Generally speaking, the normal value of blood creatinine is 44-133umol/L. When blood creatinine exceeds 133umol/L, it means that the kidneys are damaged and renal insufficiency or renal failure has occurred. (133umol/L and above is the inflammatory damage stage, 186umol/L is the renal function damage stage, and 451umol/L is the renal failure stage).

Causes of high creatinine:

1. People with existing renal insufficiency, if combined with infection, including colds, pneumonia, intestinal infections, urinary tract infections, etc., may experience elevated blood creatinine in a short period of time.

2. Water loss in the body, such as fever, sweating, reduced water intake, polyuria leading to blood concentration, reduced renal blood flow, and increased blood creatinine.

3. Patients with existing kidney disease who use drugs that damage the kidneys may experience elevated blood creatinine, which may even be irreversible.

4. Patients with existing kidney disease may experience oliguria or even anuria due to relapse of the disease, which may be combined with acute renal insufficiency, leading to increased blood creatinine.

5. Fatigue, lack of rest, and inattention to life details can also cause a transient increase in blood creatinine.

6. Existing hypertension, uncontrolled blood pressure, long-term moderate or large amounts of proteinuria (total urine protein in 24 hours greater than 1 gram or even 1.5 grams) can slowly progress to elevated blood creatinine without being noticed.

The above points are the reasons for high blood creatinine. If your blood creatinine is high, you must go to a regular hospital for routine examinations to get a confirmed diagnosis and receive appropriate treatment.
