What perimenopause feels like
The hallmark sign is cycle change - usually shorter cycles first, then longer gaps, then skipped months. Hot flashes, night sweats, sleep disruption, mood shifts, brain fog, and vaginal dryness commonly join in. Some people barely notice the transition; others find it disruptive enough to seek treatment.
What helps
Lifestyle (sleep hygiene, strength training, alcohol awareness) covers a lot of ground. For moderate-to-severe symptoms, options include hormone therapy (HRT), low-dose SSRIs for hot flashes, vaginal estrogen for GU symptoms, and cognitive behavioural therapy for sleep and mood. Track patterns first - the menstrual cycle calculator can help.
Frequently asked questions
When does perimenopause typically start?
Average onset is mid-40s, but it can start as early as the mid-30s. The transition averages 4-8 years before periods stop completely (menopause). If symptoms start before 40, mention it to a doctor - early menopause has different long-term implications.
Do I need a blood test to confirm it?
Not usually. Hormone levels swing wildly in perimenopause, so a single FSH test can be misleading. Most clinicians diagnose based on symptoms, age, and cycle history. Labs are more useful to rule out other causes (thyroid, iron) or for women under 40.
Is HRT safe?
For most women under 60 within 10 years of menopause, modern HRT is considered safe and effective for managing significant symptoms - and may have long-term benefits for bone and possibly heart health. Risks rise with age and time since menopause. Talk to a doctor about your specific situation.
