- The causality between gut microbiota and endometriosis: a bidirectional Mendelian randomization study (2024) · Frontiers in Medicine · cited 6× · doi
The current treatment for endometriosis focuses on alleviating symptoms, and there is a need for a better understanding of the underlying causes. The relevance of the relationship between gut microbiota abundance and the pathogenesis of endometriosis remains to be clarified. There is a lack of studies investigating the causal relationship between gut microbiota and endometriosis using a bidirectional Mendelian randomization approach.

the field remains dominated by correlational observations rather than experimentally validated causal mechanisms. whether gut dysbiosis is a driver, a modifier, or merely a consequence of neurodegeneration remains unresolved. establishing causality in gut microbiota-ND research has been hindered by the field's reliance on correlational data and by the methodological limits of experimental models.

The current understanding of the associations between gut microbiota and FGIDs is limited by the lack of causal inference. There is a need for a better understanding of the underlying mechanisms of FGIDs to facilitate the development of effective diagnostic and therapeutic strategies. The study aims to address this gap by investigating the potential causal relationships between gut microbiota and FGIDs using a bidirectional Mendelian randomization approach.
