Women are diagnosed with irritable bowel syndrome twice as often as men. Emerging research reveals that gut bacteria directly govern how much active estrogen recirculates systemically, while female hormones in turn shape gut motility, intestinal permeability, and microbial composition — a bidirectional relationship in which dysbiosis and hormonal dysfunction drive and amplify each other. Bacterial dysbiosis has now been linked to some of the most prevalent conditions in women's health, including PMS, PCOS, infertility, thyroid dysfunction, autoimmune disease, bone loss, cardiovascular disease, breast cancer risk, and difficult menopausal transitions. This lecture presents an evidence-based framework for assessing gut health in female patients and implementing targeted interventions — including dietary strategies, probiotics, and SIBO-directed therapies — that have been shown to reduce symptoms and improve outcomes across the female lifespan.
