Abstract

Emerging evidence highlights the critical role of the gut microbiota in the development and progression of eating disorders (EDs), particularly in women, who are more frequently affected by these conditions. Women with anorexia nervosa, bulimia nervosa, and binge eating disorder exhibit distinct alterations in gut microbiota composition compared to healthy controls. These alterations, collectively termed dysbiosis, involve reduced microbial diversity and shifts in key bacterial populations responsible for regulating metabolism, inflammation, and gut-brain signaling. The gut microbiota is known to influence appetite regulation, mood, and stress responses-factors closely implicated in the pathogenesis of EDs. In women, hormonal fluctuations related to menstruation, pregnancy, and menopause may further modulate gut microbial profiles, potentially compounding vulnerabilities to disordered eating. Moreover, the restrictive eating patterns, purging behaviors, and altered dietary intake often observed in women with EDs exacerbate microbial imbalances, contributing to intestinal permeability, low-grade inflammation, and disturbances in neurotransmitter production. This evolving understanding suggests that microbiota-targeted therapies, such as probiotics, prebiotics, dietary modulation, and fecal microbiota transplantation (FMT), could complement conventional psychological and pharmacological treatments in women with EDs. Furthermore, precision nutrition and personalized…
