What a low LDL Cholesterol can mean

  • Usually a benign or beneficial state — very low LDL is the goal in many secondary-prevention regimens.
  • Severe liver disease — impaired synthesis.
  • Hyperthyroidism — accelerated clearance.
  • Inflammation, malnutrition — transient drops.

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.
