Fatigue is the single most reported symptom among women in the perimenopausal age range, and almost nobody expects it.<\/strong> In a survey of 17,494 women across 158 countries, 71.1% named hot flashes as a sign of perimenopause. But among the 12,681 respondents aged 35 and over, 83.2% reported fatigue and 83.2% reported physical and mental exhaustion.<\/p>\n\n\n\n

If you have spent two years assuming you are just tired, or run down, or getting old, that gap is worth understanding. It is also worth saying at the outset that fatigue has many causes, several of them treatable and unrelated to hormones, and this article covers those too. Broken nights are the most common of them, and the particular pattern of waking at 3am with no hot flash attached<\/a> turns up in this age range far more than the trouble falling asleep that people expect.<\/p>\n\n\n\n

What does the research actually say?<\/h2>\n\n\n\n

The study is Hedges et al., Global perspectives on perimenopause<\/a>, published in Menopause<\/em>, the journal of The Menopause Society, with data collected between 6 December 2024 and 16 May 2025 through the Flo app. It asked two different questions of two different groups, and the contrast between the answers is the finding.<\/p>\n\n\n\n

Two honest caveats about that table, because they matter and most coverage skips them. The expectation figures come from 17,290 respondents of all ages from 18 upward. The experience figures come from 12,681 respondents aged 35 and over. These are not the same people answering both questions<\/strong>, so the numbers sit side by side rather than being a before and after. And the paper reports them descriptively. It did not statistically test the gap.<\/p>\n\n\n\n

Among the narrower group who said they were currently in perimenopause, the numbers climb: physical and mental exhaustion 94.5%, fatigue 93.3%.<\/p>\n\n\n\n

Is fatigue actually unrecognised, or just under-discussed?<\/h2>\n\n\n\n

This deserves a straight answer rather than a tidy one. The claim that nobody recognises fatigue as perimenopausal is too strong. In the study’s own data, fatigue was named by a meaningful share of respondents. What the authors state is narrower and more defensible: fatigue, irritability and digestive changes were far less likely<\/em> to be identified as part of perimenopause than hot flashes were.<\/p>\n\n\n\n

Fatigue is unambiguously in the clinical literature. The Menopause Society publishes patient material under the heading Are you just tired, or are you menopause tired?<\/a>, which is about as plain as a professional body gets. The gap is between what is in the literature and what the average person, and sometimes the average appointment, actually reaches for first.<\/p>\n\n\n\n

Why exhaustion gets attributed to everything else<\/h2>\n\n\n\n
