How gut bacteria from women with eating disorders affect digestion and behavior

Official title: Effects of Fecal Microbiota Transplantation From Patients With Eating Disorders on Body Weight Development in Mice

Run by University Hospital, Rouen · NCT07196189 · Data updated 2026-11-12

This project will test whether gut bacteria taken from women with anorexia, bulimia, or binge-eating cause changes in digestion and eating-related behavior when transplanted into mice, compared with bacteria from healthy women.

Is this trial a fit for you?

Likely a good fit

Women aged 18 to 50 who are presenting for a first consultation for anorexia nervosa, bulimia nervosa, or binge-eating disorder at Rouen University Hospital and who screen positive on the SCOFF questionnaire are ideal candidates.

Probably not a fit

Participants should not expect direct clinical benefit from participation because the protocol involves donating stool for mouse experiments rather than receiving a therapeutic intervention, and people with recent antibiotics, IBD, or prior gut surgery are excluded.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Researchers will collect stool samples from women aged 18–50 who present with anorexia nervosa, bulimia nervosa, or binge-eating disorder at Rouen University Hospital, and from matched healthy female volunteers. Fecal microbiota from these donors will be transferred into mice to see whether recipient animals develop changes in intestinal physiology, digestion, or behaviors related to eating. Results from mice receiving microbiota from patients will be compared with those receiving microbiota from healthy donors to test for a causal role of dysbiosis. The work aims to clarify microbiota-driven mechanisms that could underlie or perpetuate eating disorder symptoms and related digestive problems.

Why it matters

Potential benefit: If successful, the findings could point to new microbiome-based strategies to improve digestive symptoms and complement treatments for eating disorders.

How similar studies have gone: Previous mouse transfer experiments have linked gut microbiota to weight and behavior changes and suggest a plausible role in eating-related behaviors, but human therapeutic evidence remains limited.
