Perimenopause: the signs most women miss

Why symptoms often start in your 40s, and what treatments really help.

Read it, or listen hands-free.

Quick answer

  • Menopause means 12 months in a row without a period, usually around age 51.
  • Perimenopause is the transition before it and can start years earlier, often in the 40s.
  • Symptoms are common and treatable. Nobody has to just push through.

What's happening

Estrogen and progesterone rise and fall unevenly, then decline. Common symptoms include hot flashes, night sweats, poor sleep, mood changes, brain fog, joint aches, vaginal dryness and irregular periods.

Lower estrogen also affects bone and heart health over time.

Key facts

Symptoms are often mistaken for stress or depression.

Many women are not told their symptoms could be hormonal. Ask your provider directly.

Thinking on hormone therapy has changed a lot since the early 2000s.

For many healthy women under 60, benefits can outweigh risks. Your provider can help you decide.

Strength training protects bone and muscle.

Bones can thin faster after menopause. Muscle-strengthening activity helps slow that down.

What you can do

  • Track symptoms and cycles, and bring your notes to appointments.
  • Ask your provider about hormone and non-hormone treatment options.
  • Build strength training into your week.
  • Protect your sleep and cut back on alcohol, which can worsen hot flashes.

When to get help

  • Any bleeding after 12 months without a period.
  • Very heavy or very frequent bleeding during perimenopause.
  • Symptoms affecting your sleep, work, mood or relationships.
