5 things I tell women about perimenopause

In October 2026, Dr. Robin Arora completed The Women’s Health Summit: From Perimenopause to the Power Years, an accredited continuing medical education program from the George Washington University School of Medicine and Health Sciences (20 AMA PRA Category 1 Credits™).

As a woman and a physician, I know how easy it is to put your own health last. Perimenopause is one of the easiest things to brush off, so here is what I want every woman in her late 30s, 40s and early 50s to know.

1. It can start earlier than you think

Perimenopause is the transition before your final period. According to Cleveland Clinic, it usually begins in the mid-40s, about 8 to 10 years before menopause, but it can start anywhere from the mid-30s to the mid-50s. It lasts about four years on average and can go on for eight or more.

The first signs are often not a missed period. They can be poorer sleep, night sweats, a shorter fuse, anxiety you didn’t used to have, heavier or closer-together periods, or brain fog. If several of these show up together, it’s worth asking whether hormones are part of the picture.

2. A single blood test usually can’t tell you

This surprises a lot of women. In perimenopause, hormone levels can swing widely from one day to the next, so one normal result doesn’t rule it out and one abnormal result doesn’t confirm it. Cleveland Clinic notes that the diagnosis is usually based on your age, symptoms, cycle history and an exam.

Labs still have a place, mainly to rule out look-alikes such as thyroid problems or low iron. Read more in Do I need my hormones tested? and Is it perimenopause or your thyroid?

3. Your symptoms are real, and they can last years

Hot flashes and night sweats are not a brief phase for many women. In the Study of Women’s Health Across the Nation (SWAN), which followed more than 3,000 U.S. women, frequent hot flashes and night sweats lasted a median of 7.4 years. Women whose symptoms began early in the transition had them longest, and Black women had a median of 10.1 years.

That is a long time to sleep badly and feel unlike yourself. You don’t need to wait until it’s unbearable to ask for help.

4. Some changes need a check, not a shrug

Irregular periods are expected in perimenopause, but some bleeding patterns can have other causes and should be checked. Cleveland Clinic lists:

• Very heavy bleeding, large clots, or soaking a pad or tampon every one to two hours
• Bleeding that lasts several days longer than usual
• Spotting between periods or bleeding after sex
• Periods that come less than 21 days apart

And one more: pregnancy is still possible in perimenopause. If you don’t want to get pregnant, keep using birth control until your clinician tells you it’s safe to stop.

5. You have options, and you get to decide

Treatment is not one-size-fits-all. For some women, steady sleep habits, strength training and cutting back on alcohol make a real difference (see Strength after 40 and Mood, sleep & brain fog). Others need more, and there are both hormonal and non-hormonal medical options.

On hormone therapy, The Menopause Society’s 2022 position statement says that for most healthy women with symptoms who are younger than 60 and within 10 years of menopause, the benefits outweigh the risks. It also says the decision should be individualized and revisited over time. That is how we approach it: we go through your history, your family history and your goals, and you decide with us.

Why I’m writing this

Many women tell us it’s easier to bring this up with another woman. Whether you’d rather talk with me or with Dr. Robin Arora, who leads our hormone care, the first step is the same: tell us what you’re noticing. Our free 3-minute symptom check is a good place to start, and you can bring the results to your visit.

Every plan is individualized, and treatment is recommended only when it’s right for you after your consultation.
