An estimated 10 to 14% of women leave the workforce during menopause, according to a report cited in a study published in the journal Women's Health in 2026. The study looked at what sits behind that figure from an unusual angle: what women write about their jobs when they're anonymous and nobody at work is reading.
Menopause usually arrives between 45 and 55, and the years leading up to it, known as perimenopause, can bring hot flushes, night sweats, mood changes and broken sleep. More than a billion women worldwide are in menopause or past it, and many of them are still working. If your focus, memory or confidence at work has shifted in midlife, this research suggests you are in large company, and it points to a few practical ways to make that easier to explain and to deal with.
What the researchers found
The team, led by M. K. Grabarski, collected anonymous Reddit posts written between April 2022 and July 2024. They searched two menopause forums, r/menopause and r/perimenopause, and two work forums, r/antiwork and r/careerguidance. Three of the authors then read every post by hand and kept only those in which a woman described her own menopause and how it affected her work. That left 130 posts, which they sorted under three headings researchers use to judge whether a career can last: health, happiness and productivity.
On health, the same symptoms came up again and again: fatigue, mood swings, migraines, anxiety and brain fog. Women described how hard it was to keep up a professional image while feeling this way, and many blamed themselves and worried about performance reviews. Some described a loop in which symptoms made work harder, the pressure at work added stress, and the stress made the symptoms worse. Several said that reading other women's posts helped them make sense of what was happening and feel less alone.
Productivity was where brain fog did the most damage. Women wrote about losing words mid-sentence, gaps in memory and trouble concentrating, and about the embarrassment and loss of confidence that followed. Some faced disciplinary action or worried about keeping their jobs. One woman described how a supportive manager made the load much lighter.
The happiness theme was more mixed. Some women feared becoming less relevant and felt their professional identity slipping away. Others used this stage to rethink what they wanted from work: slowing down, moving to part-time hours, setting firmer boundaries or starting a side business. One woman said her health improved after she moved into less stressful part-time work.
What this study can and can't tell us
This is a small qualitative study, which means it describes experiences in depth rather than measuring how common they are. Because the posts were anonymous, the researchers had no ages, job titles or other background details, and they couldn't check anything or ask follow-up questions. People who are struggling at work are also more likely to post about it in the first place, so the picture may lean towards the negative. The authors say plainly that the study can't tell us how many working women go through this, or whether workplace support keeps more of them in their jobs.
What it does show is that brain fog at work is a common enough experience to fill whole forums, and that many women feel they can't raise it with anyone in the office. The authors note that menopause is still taboo in many cultures, which helps explain the silence.
Making it easier to talk about
The researchers recommend that employers offer menopause awareness training, open conversations, flexible schedules, mentoring and managers who are willing to listen.
The hardest part is often turning a vague sense of not being yourself into something specific enough to act on. A simple note kept for two or three weeks can help: the days when your focus is worst, how you slept the night before, when you last ate, and how your energy felt across the afternoon. Glucose, the sugar in your blood that your brain uses for fuel, rises and falls through the day with what and when you eat, and some people find that a foggy mid-afternoon slump follows a particular kind of lunch. Patterns like these give your GP something concrete to work with, and they make a conversation with a manager about flexible hours or a quieter afternoon much easier to start.
A written record of when your focus goes and what came before it is far harder to brush aside than a feeling.
If brain fog, low mood or poor sleep are affecting your work, it's worth talking to your GP.
Wear a sensor, log your breakfast, and your coach will tell you by lunchtime whether it worked.
