Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — hormone wellness

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.

Most of us know when something feels off — fatigue, weight gain, mood swings, poor sleep. But fewer people realise that a hormonal imbalance is often at the root. Learn how the endocrine system works, what throws it out of balance, and how at-home hormone testing can help you find answers.

What do heavy metals, neurotransmitters and hormone imbalances have in common? In this detailed case study, Dr. Kate Placzek examines Loretta — a 62-year-old postmenopausal woman with breast cancer — and shows how comprehensive testing can reveal the complex biochemical picture behind a cancer diagnosis. A compelling read for anyone interested in the role of hormones and toxic exposure in breast health.

Hot flushes, night sweats, anxiety, insomnia and brain fog — menopause can feel overwhelming. But what is actually happening biochemically? In this case study, Dr. Kate Placzek and Dr. Allison Smith walk through the test results of Julia, a newly postmenopausal woman, showing exactly how hormone and neurotransmitter imbalances drive menopausal symptoms — and what can be done about it.

Nearly a third of the UK population suffers from insomnia — yet many are still unaware of the powerful connection between hormones and sleep. When cortisol and melatonin fall out of rhythm, or when neurotransmitters are disrupted by menopause or chronic stress, restorative sleep becomes elusive. Find out whether hormones are contributing to your sleep loss — and what you can do about it.
