Perimenopause is a natural transition marked by fluctuating estrogen levels that can trigger hot flashes, mood changes, sleep disturbances, weight gain, and cognitive shifts. Understanding how estrogen supports the heart, bones, brain, and emotional well-being is essential for managing symptoms effectively. This article explores estrogen’s vital role, the science behind perimenopausal changes, treatment options including HRT and non-hormonal approaches, and the cultural history shaping how women experience menopause today. Convenient at-home hormone testing can also provide valuable insight and empower women to take control of their health during this transformative stage.

Understanding Neurotransmitter Testing: The Missing Link in Personalised Mental Health Care
Posted by Behcet Bicakci on
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.
