Studies on the relationships between gut microbiota and eating disorders.

Authors and Year Type of Study Findings
Santonicola et al., 2019 [203] Review
  • -

    Differences in alpha-diversity and composition of microbiota in EDs, possibly contributing to symptomatic manifestations and pathophysiology;
Seitz et al., 2019 [204] Review
  • -

    Decreased alpha-diversity in AN, which showed an increase during weight restoration and a correlation with depressive and anxious symptoms;

  • -

    Increased beta-diversity in AN, which decreased after weight rehabilitation;

  • -

    Specific taxa abundance in AN could influence gut permeability, inflammation and symptomatic manifestations
Seitz et al., 2019 [205] Review
  • -

    Decreased diversity and taxa abundance in AN;

  • -

    AN-related changes in microbiome could increase gut permeability, inflammation and autoantibody formation;

  • -

    Increased microbiome diversity in AN associated with depressive, anxious and EDs symptoms
