Kidney Function (Creatinine & eGFR)
Indicators of renal clearance and filtration capacity.
Clinical Relevance
Creatinine is a waste product of muscle metabolism cleared by the kidneys. The estimated Glomerular Filtration Rate (eGFR) calculation determines how effectively the kidneys filter waste.
Why It Varies
Influenced by muscle mass size, high protein intake, acute dehydration, and cardiovascular blood flow pressure.
Longevity & Lifestyle Pointers
- Ensure consistent, adequate hydration throughout the day.
- Monitor blood pressure, as hypertension is the leading driver of kidney strain.
- Maintain a balanced protein distribution rather than massive single-meal boluses.
Clinical Governance & Disclaimer
An eGFR above 90 is optimal. Values consistently below 60 require careful clinical assessment and monitoring for chronic kidney health.
