Signs of perimenopause, and what can help

Perimenopause is the time before menopause when hormone levels start to change. It often begins in your 40s and lasts about four years on average. Common signs are changes in your periods, hot flashes, night sweats, trouble sleeping, mood changes and brain fog. Menopause is confirmed after 12 months in a row without a period.

Key takeaways

  • Perimenopause often starts in your 40s, sometimes in your late 30s.
  • Changing periods are often the first sign.
  • You can still get pregnant during perimenopause.
  • Many symptoms can be treated, so it's worth talking to your doctor.

What are the first signs of perimenopause?

Signs vary a lot from person to person. Common ones include:

  • Periods that come closer together, further apart, or become heavier or lighter.
  • Hot flashes and night sweats.
  • Trouble falling or staying asleep.
  • Mood changes, irritability, anxiety or low mood.
  • Brain fog and trouble concentrating.
  • Vaginal dryness or discomfort during sex.
  • Joint aches and tiredness.

How long does perimenopause last?

On average, about four years, but it can be a few months or more than ten years. In the US, the average age of menopause is around 51. Menopause is the point 12 months after your last period.

What can help with symptoms?

Small changes help some people: keeping the bedroom cool, layering clothes, regular exercise, limiting alcohol and caffeine if they trigger hot flashes, and keeping a steady sleep routine.

There are also effective treatments, including hormone therapy and non-hormonal options. Your doctor can talk through what's right for your symptoms and health history.

Can I still get pregnant?

Yes. As long as you're still having periods, even irregular ones, you can get pregnant. Doctors usually advise using contraception until you've gone 12 months without a period, or as your doctor advises.

When to see a doctor

  • Symptoms affect your sleep, work, relationships or mood.
  • You bleed very heavily, for longer than usual, or between periods.
  • You have any bleeding after 12 months without a period.
  • You have signs of perimenopause before age 40.
  • You feel very low, anxious or hopeless. In the US, you can call or text 988.

Frequently asked questions

At what age does perimenopause start?

Most often in your 40s. Some people notice changes in their late 30s.

Can a blood test confirm perimenopause?

Usually not on its own, because hormone levels go up and down. Doctors mostly look at your age, periods and symptoms.

Is it perimenopause or something else?

Thyroid problems, anemia and depression can cause similar symptoms. That's why it's worth seeing a doctor rather than guessing.
