Perimenopause arrives unannounced

Dr Vesna Horvat · 6 min · 2026-05-25

Perimenopause is not menopause. It is the years before, sometimes as many as ten, when hormones begin to swing rather than decline smoothly. The swings are the story: oestrogen does not fade politely, it spikes and crashes.

That is why the early signs rarely look hormonal. Sleep that breaks for no reason. Anxiety arriving in a life that was steady. Cycles that shorten, then scatter. Heat that climbs the chest at midnight. A memory that drops words it never used to drop.

Women describe these symptoms to doctors and too often hear that everything is normal, because a single hormone test on a single day catches a swing at whatever point it happens to be. One blood test cannot photograph a moving target.

What actually builds the picture is tracking: symptoms, cycle length and sleep over three or four months. That record, brought to an informed doctor, changes the conversation completely.

Hormone therapy deserves an honest sentence too: for most healthy women under sixty within ten years of their last period, the benefits outweigh the risks, and the fear surrounding it traces back to a 2002 study that has since been substantially re read. Discuss it with a doctor who has kept up.

The midlife tracker on Reproductive Health builds exactly the record that makes those conversations work.
