Summary

This study looks at the link between gut bacteria and mental health symptoms like anxiety and depression in people with anorexia nervosa. Researchers will compare 120 participants (patients with severe anorexia and healthy volunteers) to see if changes in gut bacteria, intestinal health, and immune function are connected to eating disorder symptoms. The goal is to better understand these relationships, not to test a new treatment.

This is an AI summary of the original study and may miss details. Read our disclaimer.
