Written by: When you undergo a routine health checkup, one of the most critical numbers to check is Serum Creatinine. Creatinine is a chemical waste byproduct of normal muscle breakdown that healthy kidneys filter out of the blood. If your report shows elevated creatinine, it indicates that your kidneys are experiencing stress or filtration issues.
Review glomerular filtration mechanics, hypertensive renal strain, and cardiorenal syndrome in our Cardiovascular & Heart Health Hub or check parameters in our Kidney Function Test (KFT).
What Causes High Creatinine?
Elevated creatinine can be triggered by several factors, ranging from temporary lifestyle issues to chronic medical conditions:
- Dehydration: When you don't drink enough water, the concentration of waste products in your blood rises, causing a temporary creatinine spike.
- Intense Exercise or High-Protein Diets: Bodybuilders or individuals consuming high protein or creatine supplements often show slightly elevated levels.
- Chronic Hypertension & Diabetes: The two leading causes of long-term kidney damage, causing stress to the kidneys' tiny blood vessel filters.
- Medication Stress: Frequent use of NSAID painkillers can reduce blood flow to the kidneys, increasing waste retention.
Normal Reference Ranges
Normal serum creatinine typically ranges between 0.7 and 1.3 mg/dL for men and 0.5 and 1.1 mg/dL for women, reflecting differences in muscle mass.
How to Support Kidney Health
- Stay consistently hydrated by drinking 2.5 to 3 liters of water daily.
- Control underlying diabetes and blood pressure levels through diet and medication.
- Avoid self-medicating with over-the-counter painkillers.
