Perimenopause phase

Fatigue in Perimenopause

Persistent fatigue is one of the most commonly reported perimenopause symptoms. It is often linked to sleep disruption, hormonal changes, and the cumulative effect of other symptoms.

What causes it

Night sweats and sleep disruption are primary drivers — poor sleep compounds quickly. Declining progesterone (which has a calming, sleep-promoting effect) directly affects sleep quality. Thyroid changes common in perimenopause also cause fatigue. Anaemia should be ruled out.

How to track it

Log sleep quality, night waking, energy level, and mood daily. Fatigue rarely exists in isolation — tracking alongside sleep and other symptoms reveals whether it is sleep-driven, hormonal, or both.

When to see a doctor

See a doctor if fatigue is severe and persistent, or if accompanied by cold intolerance, weight gain, or hair loss — thyroid dysfunction is common in perimenopause and causes fatigue.
