50. Is PMDD a Histamine Problem H1 and H2 Blockers Explained

Could histamine be contributing to PMDD symptoms? In this episode of The Histamine Well Podcast, Joanne explores the emerging connection between Premenstrual Dysphoric Disorder (PMDD), histamine intolerance, mast cell activation, hormones, and inflammation. Learn how the estrogen-histamine feedback loop may contribute to severe mood swings, anxiety, irritability, depression, and other PMDD symptoms. Joanne explains the science behind histamine's interaction with estrogen and progesterone, the role of neurotransmitters such as serotonin and dopamine, and why some women are finding relief with H1 and H2 antihistamines. This episode also examines the potential benefits and risks of H1 blockers and H2 blockers, the role of mast cells in hormone-related symptoms, and why addressing the root causes of histamine excess may be essential for long-term relief. Joanne discusses the connections between PMDD, histamine intolerance, MCAS (Mast Cell Activation Syndrome), methylation imbalances, SIBO, mold exposure, oxalates, gut dysfunction, and hormone health, while highlighting what current research shows—and where evidence is still emerging. Whether you're a practitioner, student, or someone struggling with PMDD, histamine intolerance, hormonal imbalances, or severe premenstrual symptoms, this episode provides practical insights into one of the most talked-about topics in women's health today.
