Perimenopause is one of the most significant hormonal transitions of a woman's life — and one of the least talked about. Unlike pregnancy, which comes with a cultural script, appointments, and a clear narrative, perimenopause often arrives without announcement, is frequently dismissed by doctors, and is misunderstood even by the women going through it.
What's actually happening
Perimenopause is the transition phase leading up to menopause — defined as twelve consecutive months without a period. It can begin anywhere from your late thirties to your early fifties, with most women starting in their mid-forties, and it typically lasts between four and ten years.
During this time, the ovaries begin producing less oestrogen and progesterone. But crucially, this decline is not smooth or linear. Hormone levels fluctuate — sometimes wildly — before they gradually fall. It is these fluctuations, not simply low oestrogen, that cause many of the most disorienting symptoms.
The symptoms nobody mentions
Hot flushes and night sweats are the symptoms most associated with perimenopause, but they are far from the whole picture. Many women find that psychological and cognitive symptoms arrive first: anxiety that seems to come from nowhere, low mood, a sudden sense of not coping, poor memory, and brain fog so dense it can feel alarming.
Other common symptoms include irregular periods, disrupted sleep, palpitations, joint aches, changes in libido, vaginal dryness, and weight changes — particularly around the abdomen — despite no change in diet or exercise.
Why it's so often missed
Women in perimenopause frequently present to their doctor with anxiety, insomnia, or persistent tiredness and leave with antidepressants, a referral to a cardiologist, or reassurance that everything is fine. The hormonal cause is rarely the first explanation offered.
This is a systemic failure. Perimenopause affects every woman who reaches this life stage. Its symptoms are real, hormonally driven, and in many cases effectively treated.
What this means for you
If you are in your early-to-mid forties and noticing symptoms that don't seem to have an obvious cause — irregular cycles, mood shifts, broken sleep, or cognitive changes — perimenopause may be the explanation. You do not need to wait until symptoms are severe, and you do not have to simply accept them.
Understanding that your body is in a genuine hormonal transition — not a breakdown, not depression, not "just stress" — is often the first step toward getting appropriate support.
When to seek help
Any time. You do not need to be suffering significantly to ask for help. A doctor or gynaecologist can discuss your symptom picture, assess whether hormone therapy is appropriate for you, and support you through this transition. This is a normal life stage. You deserve care for it.
