What Causes High Creatinine Level

Creatinine is a waste product that the body produces when muscles are used. A similar substance, creatine is used by the muscles to produce energy. The muscles metabolize creatine into creatinine and then release creatinine into the bloodstream. A person’s kidneys filter creatinine from the blood and remove it from the body during urination. People with poor kidney function generally develop increased creatinine levels in the blood. this is the cause of high creatinine level.

1. Dehydration or inadequate water intake such as high fever, sweating, diuresis can cause blood concentration and reduced blood flow in the kidneys. Creatinine will increase.

2. Over-tiredness, lack of rest can cause elevation of creatinine level.

3. Urine abnormalities such as long term hematuria, proteinuria can be accompanied by high creatinine.

4. Intake of drugs that have renal toxicity can cause high creatinine which can even be irreversible.

5. If renal dysfunction patients have infections such as cold, pneumonia, intestinal infection, urinary tract infections can increase creatinine level in short time.

6. Badly controlled high blood pressure can cause high creatinine.
7. Kidney disease patients with recurrent illness conditions can have high creatinine levels.


We should pay attention to the tips above which may cause the high creatinine. Patients with high creatinine should nurse themselves well to avoid the increase of the creatinine.
