Overall blood cholesterol, one input to cardiovascular risk, not a sole verdict.
What it is
Total cholesterol in mmol/L sums cholesterol in all lipoprotein particles. BSHC notes lipids may lack a single fixed “normal” band; UK practice emphasises overall CVD risk and lipid fractions.
Total cholesterol adds cholesterol in HDL, LDL, and other lipoproteins. It is a starting number, not a complete risk assessment. UK reports use mmol/L.
Why it matters
There is no universal ideal cholesterol for everyone. UK guidance focuses on QRISK-style CVD risk, family history, diabetes, and blood pressure, not total cholesterol alone. Lifestyle and medicines are clinician-led decisions.
This guide is educational only and cannot diagnose you. Discuss results, especially anything outside your laboratory’s reference interval, or that does not match how you feel, with a GP or other appropriately qualified clinician.
How it affects the body
Cholesterol is a building block for cell membranes, steroid hormones, and bile acids. The liver and gut regulate circulating levels via lipoproteins.
Every cell membrane needs cholesterol; adrenals and gonads make steroid hormones from it; liver makes bile acids. Blood total cholesterol says little about those tissue pools and more about circulating lipoprotein traffic.
For athletes
Masters athletes still face atherosclerotic risk: fitness helps but does not grant immunity. Use full lipid profile and clinical risk assessment, not total cholesterol vanity targets.
Use full lipids and clinical risk tools. Seasonal body-mass swings move lipids; compare like-with-like training phases.
