Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — serotonin imbalance

Early menopause can cause a wide range of physical and emotional symptoms long before menopause officially begins. Learn the most common warning signs, including irregular periods, hot flashes, mood changes, sleep problems, fatigue, and hormonal imbalances, and discover when hormone testing may help provide answers.

Neurotransmitters play a vital role in regulating mood, sleep, energy, focus, and overall mental wellbeing — yet imbalances often go undetected. This article explores how dried-urine neurotransmitter testing provides an objective, science-based way to identify chemical patterns behind symptoms such as anxiety, depression, fatigue, insomnia, ADHD, and chronic stress. By analysing key markers including serotonin, dopamine, GABA, glutamate, histamine, and the kynurenine pathway, clinicians can create highly personalised treatment plans that target each individual’s unique neurochemical profile. Discover how this innovative testing method offers a deeper understanding of mind-body chemistry and a more precise path to restoring balance and emotional health.

Neurotransmitter testing is one of the most powerful functional assessment tools available — but it requires a nuanced approach to interpretation. In this clinical overview, Dr. Kate Placzek of ZRT Laboratory outlines the key fundamentals every practitioner needs before reading a neurotransmitter report: from understanding patterns over numbers and treatment sequencing, to the clinical significance of low serotonin on SSRIs, GABA’s peripheral mechanisms, and when to run a diurnal catecholamine assessment.

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.

In perimenopause, falling estradiol doesn’t just trigger hot flashes — it disrupts serotonin production, driving mood swings, brain fog and sleepless nights. Discover the hormonal science behind “the change” and how testing can help.
