Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — menopause and brain fog

Menopause is one of the most significant transitions in a woman’s life, yet it remains surrounded by confusion, misinformation, and unnecessary silence. From the first signs of perimenopause to postmenopausal symptoms such as vaginal dryness, hair loss, skin changes, and thyroid dysfunction, women deserve clear, honest, evidence-based answers. This article addresses the most frequently asked questions about menopause — covering what it is, when it happens, what causes its wide range of symptoms, and how comprehensive hormone testing can help women and their healthcare providers make informed decisions.

Early menopause affects around 5% of women aged 40 to 45, yet it is frequently misdiagnosed or dismissed. Surgical menopause — triggered by removal of both ovaries — can occur at any age and brings an abrupt loss of both oestrogen and testosterone. This article combines a first-person account of early and surgical menopause with a clinical overview of causes, health risks, and the importance of comprehensive hormone testing. Whether your menopause arrived early, unexpectedly, or surgically, understanding your hormone status is the essential first step towards effective, personalised treatment.

Hot flashes, mood instability, brain fog and memory changes during perimenopause are not “all in your head” — but they are very much in your brain. In this in-depth clinical article, Dr. Kate Placzek of ZRT Laboratory explains how declining estradiol disrupts brain glucose metabolism, neurotransmitter signalling and thermoregulation, why perimenopause represents a window of neurological vulnerability, and why the timing of hormone replacement therapy is critical to protecting long-term brain health.

The Women’s Health Initiative (WHI) trial cast a long shadow over hormone replacement therapy — but it enrolled women well over a decade past menopause. Two newer trials, ELITE and KEEPS, specifically studied HRT started early in the postmenopausal period. Their findings on cardiovascular health, sexual function, sleep, mood and cognition paint a more nuanced and encouraging picture. Here is what the latest research shows.

Estrogen dominance — an excess of oestrogen relative to progesterone — is one of the most common hormonal imbalances in women. From heavy periods and mood swings to breast tenderness and weight gain, the symptoms are wide-ranging. Discover the causes, what to test, and how to restore balance.
