The Microbiota-Mind Connection: A Novel Framework for Non-Pharmacological Management of Inflammatory Premenstrual Syndrome Pathophysiology

Abstract

Premenstrual Syndrome (PMS), particularly its inflammatory manifestations, remains a therapeutic challenge with significant impacts on quality of life. Emerging evidence positions the gut-brain axis as a critical modulator of systemic inflammation and mood. This review synthesizes cutting-edge research (2024-2025) to explore the hypothesis that dysbiosis-driven inflammatory cascades underpin key PMS symptoms and that microbiome-targeted non-pharmacological interventions offer a viable adjunct therapeutic pathway. A narrative review of literature published between January 1, 2024, and November 30, 2025, was conducted using PubMed, Scopus, and Web of Science. Search terms included “gut-brain axis,” “microbiome,” “premenstrual syndrome,” “inflammation,” “probiotics,” “diet,” “stress,” and “cyclic inflammation.” Human, animal, and mechanistic studies were included. Recent studies confirm cyclical fluctuations in gut microbiota composition linked to ovarian hormones, revealing a state of luteal phase dysbiosis in individuals with PMS. This dysbiosis is associated with increased intestinal permeability, elevated circulating lipopolysaccharides (LPS), and a consequent upregulation of pro-inflammatory cytokines (IL-6, TNF-α, CRP). These inflammatory markers correlate strongly with somatic symptoms (bloating, mastalgia, fatigue) and affective disturbances (irritability, low mood). Interventions such as specific probiotic strains (e.g., Lactobacillus helveticus, Bifidobacterium longum), targeted prebiotic fibers, cyclical dietary modifications, and stress-reduction techniques like mindfulness-based therapy demonstrate efficacy in restoring microbial eubiosis, dampening inflammation, and mitigating symptom severity. The gut-brain axis represents a dynamic and modifiable interface in PMS pathophysiology. A paradigm shift towards integrative, microbiome-centric non-pharmacological strategies personalized to the hormonal cycle holds significant promise as an adjunct to standard care. This review provides a framework for clinical application and directs future research toward precision interventions.
