Everyone told you about hot flashes. Nobody warned you that perimenopause symptoms would show up as exhaustion, a waistline you did not earn, and anxiety you never used to have.
You do not have to be menopausal to have every symptom on this list.
Perimenopause is the stretch of years when your ovaries have not quit but have stopped working with the regularity they had at 25. It usually starts in your forties, it can start earlier, and it can run for years before your periods stop for good.
The symptoms reach far past hot flashes. I am a board-certified OB/GYN with 23 years in private practice, and at Elle Medicine, my concierge practice for women in Dallas, the thirteen below are what women actually bring into the room. Most of them were never connected to hormones by anyone, including the woman living with them.
What perimenopause actually is
I love the definitions people bring in. “I think I am perimenopause.” “I am menopaused.” Let’s get this together.
Your ovaries work differently at 40 than they did at 20. That is obvious, otherwise everyone would still be getting pregnant at 45.
Menopause is reached after twelve consecutive months without a period. By then, the ovaries are no longer releasing eggs, and their production of estrogen and progesterone has dropped significantly.
Perimenopause is the time leading up to that, when the ovaries are sputtering along. They have not quit. They have just lost that beautiful regularity they had when you were younger.
And that is different for everyone. Some women have a period every month and then simply stop. Others have years of crazy bleeding and crazy symptoms before their periods stop completely. Your ovaries can work great for six or twelve months, and you think it is over, and then a few months later you are back in crazy town. They work, then they do not, then they do.
That is the nature of the beast.
How early it can start, and how long it lasts
The average age of menopause in the United States is 52 (Office on Women’s Health). Perimenopause runs ahead of that, and it is not necessarily short.
Some symptoms can also continue beyond the final period. In one major long-term study, hot flashes and night sweats lasted a median of 7.4 years (JAMA Internal Medicine, 2015).
It can also start far earlier than anyone expects. Sadly, very early. Ovarian function can decline in your twenties or your late thirties. When it happens before age 40, it may be diagnosed as primary ovarian insufficiency. Sometimes there is an identifiable medical, genetic or treatment-related cause. Other times, even after an evaluation, the reason remains unclear.
It is not common, but it absolutely happens.
And you do not have to be menopausal to have every symptom on this list. That is the part most women have never been told.
The 13 perimenopause symptoms women actually bring me
Hot flashes and night sweats are the two you already know. These are the rest, roughly in the order I hear them.
- Changes in weight and body composition. Often through the middle, sometimes without any obvious change in how you eat.
- Fatigue. The one I hear most. Tired in a way that sleep does not fix.
- Insomnia. Falling asleep, staying asleep or waking at three with your mind running.
- Anxiety that was never there before. You did not used to feel this way. Now you do.
- Depressive symptoms. Flat, low, not yourself.
- Low libido. Gone, and you cannot say when it left.
- Vaginal dryness. And intercourse that is uncomfortable when it never used to be.
- Urinary symptoms. Leaking, urgency and pelvic floor changes nobody mentions at a well visit.
- Loss of muscle tone. Same workouts, less back.
- Recovery that takes two days. You can get through the workout. Then you need to lie down for two days.
- Hair loss. Always a big one.
- Brain fog. Losing a word you have used a thousand times. Hormonal changes and disrupted sleep may contribute, but persistent or concerning cognitive changes deserve a broader evaluation.
- Periods that stop making sense. Heavier, lighter, closer together, gone for months and back again.
Changes in bleeding are common during perimenopause, but they should not automatically be blamed on hormones. Very heavy bleeding, bleeding between periods, bleeding after sex or any bleeding after menopause needs to be evaluated.
Why nobody warned you
Most women are braced for hot flashes and get something else entirely.
In an international app-based survey of 17,494 women across 158 countries, hot flashes were the symptom women most often associated with perimenopause, at 71 percent. Among participants over 35, what women actually reported most was fatigue and physical and mental exhaustion, each at 83 percent (Mayo Clinic and Flo, published in Menopause, 2026).
So you are tired, you are anxious, you are gaining weight, and none of it matches the picture of perimenopause symptoms you were given. You assume it is stress, or age, or you.
Hormonal changes may be part of the picture, and the fact that nobody connected those dots is not a failure on your part.
It is not simply your doctor either. In a 2019 survey of residents from 20 U.S. training programs, only 6.8 percent said they felt adequately prepared to manage menopause (Mayo Clinic Proceedings, 2019). The training was not there. That is changing, and it explains a great deal.
What to do with this list
Take this list of perimenopause symptoms to your next appointment—whichever ones are yours. Write down when each one started and how bad it is.
Fifteen minutes rewards data and punishes memory.
Then ask for the number, not the word. Thyroid problems are far more common in women than in men, and your thyroid can be normal and still not be optimal for you. Normal is a range built from everybody. Optimal is built for you.
And know that a perimenopause symptom on this list does not automatically mean hormone therapy. Maybe it does. Maybe the answer is sleep, or something you are not absorbing, or something nobody has looked at yet.
What it always means is that you deserve a physician who has a clue what is going on with your hormones—and the time to find out.
Your ovaries are going to do what they are going to do. How you feel through it is a different question, and that one has answers. That is what it means to Unrush Your Health®, and it is what we work on every day at Elle Medicine.
