Examination

Diagnosis

  • • ≥3 of: waist ≥90 cm (M)/80 cm (F) Asians, TG ≥150, HDL <40 M/<50 F, BP ≥130/85, FBG ≥100

Initial treatment / management

  • • Lifestyle modification first-line
  • • Treat each component to target

Drug therapy

  • • Statin if 10-yr CVD risk ≥10%
  • • ACEi/ARB for BP
  • • Metformin if prediabetes / IGT

Lifestyle advice

  • • Aerobic + resistance exercise 150–300 min/week
  • • 5–7% weight loss

Follow-up advice

  • • Review in 2–4 weeks or earlier if worsening
