Creatinine is a chemical waste product in the blood that passes through the kidneys to be eliminated in urine. The kidneys may not be functioning properly if the body has high levels of creatinine. The normal range of creatinine in blood is:
0.5 to 1.1 mg/dL (or 44 to 97 mcmol/L) for females
0.6 to 1.2 mg/dL (or 53 to 106 mcmol/L) for males
Because creatinine increases with muscle mass, men have usually higher levels than women.
Factors that contribute to high creatinine levels include:
- Dehydration or inadequate water intake
- Kidney problems
- Excessive blood loss
- Strenuous exercise
- Chronic diseases like kidney disease, diabetes, high blood pressure and thyroid disorders
- Medications like ACE inhibitors, NSAIDs like ibuprofen and aspirin, chemotherapy drugs and others
- Eating large amounts of meat, muscle building, and taking the dietary supplement creatine can elevate creatinine levels.
Common symptoms of high creatinine are:
- Urinary changes like frequent night urination, decreased urine output, and dark colored urine
- Itchy skin
- Shortness of breath
- Digestive problems like poor appetite, nausea, and vomiting
It is best to see your doctor for proper diagnosis and treatment, as high creatinine levels may indicate kidney problems and kidney damage.
