Key takeaways

  • Average duration: 4-8 years
  • Smoking shortens timeline by ~2 years
  • Family history is a moderate predictor — mother's timing predicts yours within 2-3 years

The 4-stage perimenopause model

STRAW+10 framework breaks perimenopause into early and late stages, distinguishing variable cycles (early) from prolonged amenorrhea (late, within 1-2 years of menopause).

Factors that lengthen or shorten

Smoking accelerates by ~2 years. Genetics affect timing significantly. BMI extreme highs or lows shift timeline. Surgical interventions (oophorectomy) cause sudden menopause regardless of age.
