National Kidney Foundation creatinine high causes how to lower creatinine kidney disease
Do you mean creatinine on a kidney blood test, or the creatine supplement?
If you mean high creatinine, the goal is not to lower the number by itself. It is to find and treat the cause. Creatinine varies with muscle mass, diet, hydration, exercise, supplements, and kidney filtration, so the key results are usually eGFR and a urine albumin-creatinine ratio (uACR), not creatinine alone. The National Kidney Foundation explains this relationship.
What to do:
- See a clinician promptly for repeat creatinine/eGFR, urinalysis/uACR, blood pressure, and review of medicines.
- Stay normally hydrated unless you have a fluid restriction from heart or kidney disease. Do not force excessive water.
- Avoid NSAID pain medicines such as ibuprofen, naproxen, and diclofenac unless your clinician says they are safe. They can harm kidney function, particularly with dehydration or existing kidney disease.
- Review supplements. Creatine supplements, very intense exercise, and a large cooked-meat meal before testing can raise measured creatinine. Do not stop prescribed medicine on your own.
- Control blood pressure and diabetes if present. These are leading causes of chronic kidney disease. A clinician may use kidney-protective medicines depending on your situation.
- Avoid smoking, limit salt, and follow a dietitian or kidney clinician’s protein advice rather than drastically restricting protein yourself. Treatment focuses on the underlying cause and risk factors, as summarized by the National Kidney Foundation.
Get urgent medical care today if you have very little or no urine, new swelling or shortness of breath, confusion, severe vomiting/diarrhea, chest pain, or a rapidly rising creatinine.
If you share the creatinine value, eGFR, age, sex, current medicines/supplements, and whether this is a new result, I can help interpret what it may mean.
