Summary

This study looks at the connection between gut bacteria, body fat changes, and fear of gaining weight in people with anorexia nervosa. Researchers will collect stool and blood samples from 60 women admitted for refeeding to analyze their gut microbiome. The goal is to find biomarkers that could explain why some patients struggle more with weight regain. No treatment is given; this is an observational study to better understand the disease.
