Perimenopause: 5 Things Most Women Don’t Know

If you've been waking up at 3 a.m., losing your train of thought mid-sentence, or feeling more on edge than usual, perimenopause may be part of the picture, even if your periods haven't changed much. It's a stage of life that still doesn't get talked about nearly enough, and there's a lot more to it than hot flashes.

Here are five things we wish every woman knew, including new research on a supplement you probably associate with the gym.

1. Perimenopause can start while you're still getting regular periods

Perimenopause is the transition leading up to menopause. It often begins in your 40s and can last several years. Menopause itself is a single point in time: 12 months in a row without a period, when nothing else explains it.

During perimenopause, estrogen and progesterone rise and fall unpredictably instead of tapering off in a straight line. Early cycle changes can be easy to miss, like a period that shows up a few days early or runs heavier than it used to.

2. Hot flashes are only one piece of the puzzle

Lighter sleep, anxiety, irritability, heavier periods, achy joints, and brain fog (the walk-into-a-room-and-forget-why kind) can all show up during this transition. Some women notice these long before their first hot flash.

Many of these symptoms also overlap with thyroid changes, low iron, and blood sugar swings, which is why we look at the whole picture before chalking everything up to hormones. If stiff, achy joints are part of your story, our post on pain that keeps coming back is a good next read.

A simple log of your cycle, sleep, and mood over a couple of months can make your next appointment a lot more productive.

3. A "normal" hormone test doesn't rule it out

Because hormone levels can swing from one week to the next during perimenopause, a single blood draw is only a snapshot. You can have textbook symptoms and still get labs back in the normal range.

For women 45 and older, perimenopause is usually identified by symptoms and cycle changes. Labs still matter for ruling out other causes and shaping a treatment plan, especially if you're younger or your symptoms don't fit the typical pattern.

4. Creatine may be worth asking about

Creatine is best known as a strength supplement, but it's quickly becoming one of the most talked-about tools for women in midlife. Your brain and muscles both run on it for quick energy, and women naturally store an estimated 70 to 80% less of it than men, a gap that may matter even more as estrogen shifts. In a 2025 study, perimenopausal and menopausal women who took creatine daily had faster reaction times and more creatine in the brain after just eight weeks. Paired with strength training, it has also been shown to help protect hip bone strength and support lean muscle after menopause.

One heads-up: creatine can raise creatinine, a kidney marker on routine bloodwork, so let your practitioner know you're taking it.

5. You don't have to wait for your periods to stop to get support

Treatment can start well before menopause. Depending on your symptoms and health history, that might include bioidentical hormone therapy, nonhormonal medications, acupuncture, or targeted nutrition and lifestyle changes. Dr. Ashley Maltz walks through the hormone side in An Integrative Medicine Guide to HRT and Perimenopause, including why progesterone matters and when HRT may not be the right fit.

The foundations help no matter which path you choose: strength training a couple of times a week, enough protein and fiber, a steady sleep schedule, and going easier on alcohol.
