Encapsulated faecal microbiota transfer in young women with anorexia nervosa: an open-label feasibility pilot trial - Nature
Eating Disorders (Google News) · December 14, 2025
In plain language
Recent research suggests that the gut microbiome, which consists of trillions of tiny organisms in the digestive tract, may be linked to the development of anorexia nervosa. A small pilot study tested if fecal microbiota transfer (FMT) delivered through capsules could help restore a healthier bacterial balance in young women with this condition. The study found that the treatment was generally well-tolerated and successfully introduced new, healthy species of bacteria into the participants' systems. While the results showed some possible reductions in anxiety, more large-scale trials are needed to confirm if this approach can safely improve recovery outcomes.

Key takeaways
- Fecal microbiota transfer via oral capsules was shown to be a feasible and well-tolerated treatment for young women with anorexia.
- The treatment successfully introduced an average of 38 new bacterial species into the gut microbiomes of participants.
- Healthy donor bacteria remained present in the participants' digestive systems for at least 12 weeks after the procedure.
- Side effects were mostly mild to moderate and were similar to symptoms typically experienced by people with anorexia.
- Preliminary data suggested potential improvements in anxiety and metabolic health, though further research is required to prove effectiveness.
- The study provides a foundation for future larger clinical trials to explore how gut health impacts eating disorder recovery.
