Abstract:

The microbiota-gut-brain axis (GBA) constitutes a two-way regulatory system that incorporates microbial metabolites, epithelial barrier health, immune signaling, autonomic routes, and neuroendocrine responses. Mechanistic progress evidences that the cytokine cascades, short-chain fatty acids, vagal modulation and hypothalamic-pituitary-adrenal axis interactions play a role in multisystem conditions that cut across gastrointestinal, neuropsychiatric, and metabolic disorders. In spite of the fact that this scientific framework has grown up, health professions education is still structured largely in terms of compartmentalized organ-based models, constraining learners' ability to use systems-informed solutions to problematic clinical presentations. This study is a narrative review that synthesizes and evaluates recent mechanistic and translational literature (2020-2025) and explores ways in which the curriculum can be improved. The research suggests a competency-based framework of combining GBA literacy longitudinally in foundational sciences, clinical education, and evaluation frameworks. The framework puts emphasis on mechanistic coherence, structured curriculum mapping, case-based and simulation-based reinforcement, as well as alignment with competency-driven evaluation. Integration is viewed as restructuring of the curriculum as opposed to expansion, thus alleviating overloading of content. The heterogeneity of evidence of microbiome, the risk of premature clinical extrapolation, and faculty development and educational outcomes research should be critically taken into consideration. The integration of curricula with current systems biology can enhance diagnostic reasoning, cross-disciplinary cooperation, and evidence-based patient care. Critical and proportionate incorporation of gut-brain science provides an example of how translational gains can be offered even-handedly in coherent clinical training in a mature and continuously intricate chronic disease.
