Cholesterol: Understanding Your Numbers and Reducing Your Risk

A full cholesterol panel (lipid profile) reveals your cardiovascular risk. Most people can significantly improve their numbers with lifestyle changes — and medication when needed.

Total cholesterol target
<5.0 mmol/L
LDL target (high risk)
<1.8 mmol/L
HDL — protective
Higher is better (>1.0 men; >1.2 women)
Fasting required
Yes — 9–12 hours

The Lipid Panel Explained

TestOptimalHigh Risk RangeRole
Total cholesterol<5.0 mmol/L>6.5 mmol/LOverall lipid load
LDL cholesterol<3.0 mmol/L (general); <1.8 (high CVD risk)>4.0 mmol/L'Bad' cholesterol — deposits in arteries
HDL cholesterol>1.0 (men); >1.2 (women) mmol/L<1.0 mmol/L'Good' cholesterol — removes LDL from arteries
Triglycerides<1.7 mmol/L>5.6 mmol/L — pancreatitis riskFat from diet and liver; raised by alcohol & sugar
Non-HDL cholesterol<4.0 mmol/L>5.0 mmol/LBetter predictor than total cholesterol

Diet Changes That Work

Statins Are Highly EffectiveStatins (atorvastatin, rosuvastatin) reduce LDL by 30–50% and significantly reduce heart attack and stroke risk in high-risk individuals. Muscle aches are the main side effect — discuss with your GP.
Should everyone with high cholesterol take a statin?
Not necessarily. The decision depends on your overall 10-year cardiovascular risk score (QRISK3), not just the cholesterol level alone. Discuss with your GP.
Can I lower cholesterol without medication?
Yes — for mild-to-moderate elevations. Diet changes, exercise, and weight loss can reduce LDL by 10–20%. However, familial hypercholesterolaemia usually requires medication regardless.
What is familial hypercholesterolaemia?
A genetic condition causing very high LDL from birth (often >5 mmol/L). Affects 1 in 250 people. Requires medication from an early age to prevent premature heart disease.
How often should I have my cholesterol checked?
Every 5 years if normal and low risk; annually if on treatment or high-risk. More frequently if levels are being treated or optimised.
