Could histamine be contributing to Premenstrual Dysphoric Disorder (PMDD)?

In this episode of The Histamine Well Podcast, Joanne explores the growing interest in the connection between PMDD, histamine intolerance, mast cell activation, and hormonal fluctuations. As more women report improvements in PMDD symptoms with antihistamines, the question is gaining attention: could histamine be a missing piece of the PMDD puzzle?

Joanne breaks down the science behind the estrogen-histamine feedback loop, explains how histamine interacts with estrogen and progesterone throughout the menstrual cycle, and discusses why some women experience worsening mood symptoms during the luteal phase.

You'll learn about the role of mast cells, neurotransmitters, neuroinflammation, and hormone sensitivity in PMDD, as well as the potential benefits and limitations of H1 and H2 antihistamines. Joanne also shares her clinical observations on histamine-related hormone symptoms and why addressing underlying drivers of histamine excess may be essential for long-term symptom improvement.
