About this trial

This study is being conducted to investigate gut-brain communication in individuals with functional dyspepsia and anorexia nervosa. The hope is that what the investigators learn from this study will improve the understanding the conditions better to improve treatments.

Trial outcomes

Primary outcomes

1

Visual interoception task

The study team will be investigating brain activity and connectivity during an interoception task. This will be measured via functional magnetic resonance imaging (fMRI) which is able to measure blood flow to regions of the brain.

Time frame
Day 1, visit 1, 30-minute scan and visit 2 (within approximately two weeks of day 1), 30-minute scan
2

Resting state connectivity

Change in brain activity during rest pre and post prandially using functional magnetic resonance imaging (fMRI).

Time frame
Visit 2 (second visit, within approximately 2 weeks of day 1 of the study), 60 minute scan.
3

Gastric peristaltic velocity

MRI-derived gastric motility outcome

Time frame
30 minutes (only in Visit 2, within approximately two weeks of Visit 1)
