Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — breast tenderness

PMS and PMDD are more than hormonal mood swings—they are complex neuroendocrine conditions driven by interactions between sex hormones and neurotransmitters like serotonin, GABA, and cortisol. This article explains the science behind menstrual mood disorders and highlights how advanced hormone and neurotransmitter testing from Hormone Lab UK and ZRT Laboratory can help identify imbalances and guide personalised treatment.

Hormonal contraception suppresses ovarian function, which means saliva and blood spot hormone test results will appear artificially low — but this doesn’t mean hormone levels at the tissue level are low. This guide explains how to interpret hormone test results correctly when using the pill, patch, ring or IUD, and when to collect your sample for the most meaningful data.

Explore the powerful connection between hormones, neurotransmitters, and mood in PMS and PMDD. Learn how progesterone, allopregnanolone, GABA, serotonin, cortisol, and estrogen fluctuations throughout the menstrual cycle may contribute to anxiety, irritability, depression, fatigue, sleep disturbances, and severe premenstrual symptoms. Discover how hormone and neurotransmitter testing can help identify underlying imbalances linked to menstrual mood disorders. 

Low libido in perimenopause is rarely just one thing — it’s a mosaic of hormonal, physical and lifestyle factors. From falling oestrogen and DHEA to thyroid dysfunction and metabolic syndrome, discover what’s really driving the loss of desire and how hormone testing can help.
