Perimenopause is the transitional period leading up to the final menstrual period. It commonly begins in the mid-forties, though it can start earlier, and it typically lasts several years. During it, hormone levels fluctuate rather than simply declining — which is why symptoms can be inconsistent, and why a single blood test is often unhelpful for diagnosis in this phase.
The symptom list is wider than most people expect
Beyond changes in cycle length and hot flushes, commonly reported experiences include disrupted sleep, night sweats, mood changes, anxiety, difficulty concentrating or word-finding, joint aches, migraine changes, palpitations, vaginal dryness and shifts in body composition. These are frequently attributed to stress, workload or aging — sometimes correctly, often not.
Perimenopause is generally diagnosed from symptoms and cycle pattern in the appropriate age range, not from a single hormone level. Fluctuation is the defining feature.
Why it matters clinically, not just symptomatically
The menopausal transition coincides with measurable shifts in cardiovascular risk factors, changes in bone density, and changes in body composition. That makes it a sensible point to review blood pressure, lipids, glucose, bone health and activity — regardless of how disruptive the symptoms themselves are.
Treatment is a conversation, not a verdict
Options range from behavioural and lifestyle approaches through non-hormonal medications to menopausal hormone therapy. Understanding of hormone therapy has changed considerably over the past two decades, and current guidance emphasizes individualized assessment — age, time since menopause, symptom burden, personal and family history — rather than a blanket answer in either direction. That assessment belongs with a clinician who knows your history.
What is worth bringing to the appointment
- A record of cycle timing and length over several months.
- Which symptoms affect you most, and how they affect sleep, work and relationships.
- Personal and family history relevant to cardiovascular disease, blood clots, breast cancer and osteoporosis.
- Current medications and supplements.
If you have raised these symptoms before and been told they are unrelated to hormonal change, a second opinion is reasonable. Wide variation in how well this transition is managed is well documented.
