High Creatinine: what it means
A Creatinine result above the normal range is considered high. Here is what a raised Creatinine can point to, and when it is worth discussing with a doctor.
Reference range: Men 0.7–1.3 mg/dL; Women 0.6–1.1 mg/dL

What a high Creatinine can mean
- Acute kidney injury — dehydration, drug toxicity (NSAIDs, contrast media, certain antibiotics), urinary obstruction.
- Chronic kidney disease — diabetes, hypertension, glomerulonephritis are the top causes.
- High muscle mass / heavy meat meal — modest rise without true kidney injury.
- Some medications — trimethoprim and cimetidine block tubular secretion of creatinine without changing actual filtration.
When to discuss with a doctor
Sustained eGFR <60 (typically pairs with creatinine >1.3 in men, >1.1 in women) is the threshold for chronic kidney disease and warrants a primary-care work-up. Sudden creatinine jumps within days/weeks are acute kidney injury and need urgent evaluation. Mediora.AI plots your trajectory; treatment of CKD is highly individualised and requires a clinician.
How to bring a high Creatinine down
A raised Creatinine is not brought down by diet or habits. It reflects something else going on, so what actually helps is finding that cause with a doctor - the value follows once the cause is addressed.
