Gut-Brain Axis Research

Biomarkers In Eating Disorders

Biomarkers In Eating Disorders

The gut microbiota are microorganisms that reside in the intestinal tract, and differ in humans based on their environmental exposures, such as antibiotic use, dietary experiences in childhood, and body mass index. The gut microbiome has been linked to alterations in metabolism, body mass index, and mood symptoms, and has been proposed as a mediator related to both stress and neuroinflammation.

This pilot project will measure inflammatory cytokines and the gut microbiota in three groups of women: those with current or past anorexia nervosa, those with bulimia nervosa, and healthy controls.

Our aim is to evaluate whether gut microbiota differ among the three groups and whether inflammation is related to psychiatric symptoms of Eating Disorders.

What does this study entail?

The study involves online questionnaires, clinical interviews, blood collection, and delivery of stool samples. Participants will be able to complete the study in two visits - one will be virtual and one will be in person.

How long does each visit last?

In general, each visit may take up to an hour to complete.
