How long does each phase of menopause actually last?
Most women think menopause is one long phase.
It’s not. There are three distinct stages, each with different timing.
Perimenopause
• Usually starts in your 40s (sometimes late 30s)
• Can last 4–10 years
• Hormones fluctuate
• Periods become irregular
• Symptoms often include sleep issues, anxiety, brain fog, weight changes, and mood shifts
This is when many symptoms start — even if your period hasn’t stopped.
Menopause
• This is one moment in time, not a phase
• Defined as 12 consecutive months without a period
• Average age is around 51
That’s it. One day marks menopause.
Postmenopause
• Begins after menopause
• Lasts the rest of your life
• Hormones remain lower and more stable
• Focus shifts to long-term health: bone, brain, heart, muscle, and quality of life
Why this matters:
Knowing which phase you’re in changes how symptoms are interpreted and treated.
If hormones feel confusing, it’s often because no one explained the timeline.
