High LDL Cholesterol: what it means

A LDL Cholesterol result above the normal range is considered high. Here is what a raised LDL Cholesterol can point to, and when it is worth discussing with a doctor.

Reference range: Optimal <100 mg/dL; <70 mg/dL for very-high-risk patients

What a high LDL Cholesterol can mean

  • Atherogenic burden — every 1 mmol/L (38.7 mg/dL) reduction lowers major vascular events by ~22%.
  • Familial hypercholesterolaemia — values >190 mg/dL without lifestyle cause warrant genetic evaluation.
  • Dietary pattern — saturated fat and trans fat raise LDL more than dietary cholesterol does.
  • Hypothyroidism, nephrotic syndrome, cholestatic liver disease — secondary causes worth excluding.

When to discuss with a doctor

Risk-targeted thresholds (per ESC 2021 and AHA 2019): <100 mg/dL for low risk, <70 for high risk, <55 for very-high risk (prior heart attack, diabetes with target-organ damage, peripheral arterial disease). Mediora.AI plots your trajectory; lifestyle plus statin therapy decisions need a clinician who knows your full risk picture.

How to bring a high LDL Cholesterol down

  • Diet - reduce saturated fat (fatty meat, butter, palm/coconut oil), add soluble fibre (oats, legumes, fruit) and plant sterols.
  • Regular aerobic activity and weight loss lower LDL modestly and improve the whole lipid panel.
  • Stop smoking - it doesn't lower LDL directly but sharply cuts the cardiovascular risk LDL contributes to.
  • Statins and other lipid therapy lower LDL substantially - if your risk is raised, discuss whether medication is right for you.
  • Recheck after about 8-12 weeks of any change.
