Headaches vs Migraines: How to Tell the Difference
Most women know the word menopause. Far fewer are prepared for perimenopause — the transitional phase that can begin anywhere from your late thirties to your late forties, sometimes years before your periods actually stop. It is one of the most significant hormonal shifts a woman will experience, and yet it remains one of the least discussed.
At Athelas Medical, Dr. Sofia Marchetti sees this pattern repeatedly: patients arriving confused, exhausted, and often relieved simply to have a name for what they have been going through.
What Is Perimenopause?
Perimenopause literally means around menopause. It is the window of time — which can last anywhere from two to ten years — during which your ovaries gradually begin producing less oestrogen. Your periods may become irregular, heavier, lighter, or unpredictable. But the hormonal fluctuations happening beneath the surface affect far more than your cycle.
Menopause itself is defined as 12 consecutive months without a period. Everything leading up to that point is perimenopause. The distinction matters, because many women are told they are not yet menopausal and therefore sent away without support — even when they are already experiencing significant symptoms.
The Symptoms Nobody Warned You About
Hot flushes and night sweats are the symptoms most commonly associated with this stage of life. But for many women, those are not the first signs — or even the most disruptive ones.
The symptoms that most frequently go unrecognised include:
Disrupted sleep. Waking at 3am with a racing mind, difficulty falling back to sleep, and exhaustion that no amount of rest seems to fix. This is often one of the earliest signs, appearing years before any change in periods.
Brain fog. Difficulty concentrating, forgetting words mid-sentence, feeling mentally slower than usual. This symptom is frequently dismissed — by doctors and by women themselves — as stress or overwork.
Mood changes. Anxiety, low mood, irritability, and a sense of feeling unlike yourself. Because these symptoms overlap with depression and anxiety, they are often treated as such without the underlying hormonal cause being considered.
Changes in libido. A reduction in sexual desire is common during perimenopause and is directly connected to falling oestrogen and testosterone levels. It is a medical symptom, not a personal failing.
Joint pain and muscle aches. Oestrogen has an anti-inflammatory effect in the body. As levels drop, some women experience new or worsening joint discomfort — particularly in the hands, knees, and hips.
Skin and hair changes. Drier skin, increased hair shedding, and changes in skin texture are all hormonally driven and often appear before the more well-known symptoms.
Why So Many Women Go Undiagnosed
There are several reasons perimenopause is frequently missed or mismanaged. First, hormone levels during perimenopause fluctuate significantly — a single blood test can appear entirely normal even when a woman is symptomatic. This leads many GPs to rule out a hormonal cause prematurely.
Second, the symptoms are diffuse. Brain fog, poor sleep, and low mood could each have a dozen explanations. Without a clinician who takes a comprehensive history and considers the full picture, individual symptoms get treated in isolation rather than recognised as part of a pattern.
Third, there remains a cultural tendency to normalise these experiences as simply part of ageing or being busy. Women are often told to push through, reduce stress, or sleep more — advice that, while well-intentioned, does nothing to address the underlying cause.
What Testing Can Tell You
A hormone panel — including FSH, LH, oestradiol, and testosterone — can provide useful information, particularly when interpreted alongside your symptoms and menstrual history. However, Dr. Marchetti is careful to emphasise that perimenopause is a clinical diagnosis. Normal blood results do not rule it out, and the conversation should never begin and end with a number on a page.
At Athelas, the approach is to spend time understanding the full picture: your cycle history, your symptoms, their onset and pattern, your family history, and your personal preferences for management. That conversation takes time — which is precisely why private care makes such a difference at this stage of life.
Your Options for Management
The conversation around hormone replacement therapy has changed considerably over the past decade. The large studies that led to widespread fear about HRT in the early 2000s have since been re-evaluated, and current evidence supports the use of HRT for most healthy women under 60 who are within ten years of their last period — with significant benefits for symptom relief, bone density, and cardiovascular health.
That said, HRT is not the right choice for everyone. For women who cannot take it or prefer not to, there are evidence-based alternatives including certain antidepressants for hot flushes, cognitive behavioural therapy for mood and sleep symptoms, and lifestyle interventions around exercise, nutrition, and stress management that have good supporting evidence.
The right approach is the one that is right for you — informed by your full medical history, your symptoms, and your preferences. There is no single protocol. There is only a conversation worth having.
When to Seek Support
If you recognise yourself in any of the above — if your sleep has changed, your mood feels unfamiliar, your energy has shifted, or your cycle has become unpredictable — it is worth speaking to a specialist. You do not need to wait until your symptoms become severe. You do not need to simply cope.
At Athelas Medical, Dr. Marchetti offers dedicated women's health consultations with the time and focus this stage of life deserves. Same-day appointments are available. No referral needed.
