Brief Summary

This study evaluates four different meals and how they induce gastrointestinal symptoms in children with functional dyspepsia. All subjects will receive each meal and rate their gastrointestinal symptoms during each meal.

Detailed Description

Food can often exacerbate gastrointestinal symptoms in adults and children with functional dyspepsia. However, it is unclear which foods exacerbate symptoms more than others.

Children with post-prandial distress functional dyspepsia will receive four different meals with variables being: semi-solid vs. solid and high fat vs high carbohydrate. At the time of ingestion and for up to 3 hours after each meal, subjects will rate their gastrointestinal symptoms. Comparisons of symptom onset and severity will be made for each meal.

Enrolled subjects will have undergone previous gastrointestinal evaluations: gastric emptying study and/or upper endoscopy. In addition, subjects will complete psychosocial measures: Behavioral Assessment for Children-3, childhood somatization inventory.

The first goal is to compare the severity of gastrointestinal symptoms with different composition and consistency meals. The second goal is to correlate the severity of postprandial gastrointestinal symptoms to psychosocial distress, gastric neuromotor function (emptying and accommodation), and duodenal inflammation.

Primary Outcome Measures
NameTimeMethod
Dyspepsia Symptom Severityup to 16 weeks

Change from baseline gastrointestinal symptoms using total visual analogue scale score

Secondary Outcome Measures
NameTimeMethod
Gastric accommodationup to 16 weeks

Gastric accommodation will be determined from a previously completed 4-hour gastric scintigraphy study using analysis of the time zero image.

Dyspepsia Symptom Onsetup to 16 weeks

Time to maximum symptom severity

Psychosocial distressup to 16 weeks

Anxiety, Depression, and Somatization will be determined using Behavioral Assessment for Children-3 (t-scores for anxiety and depression) and Children's Somatization Inventory Score (total score).

Duodenal inflammationup to 16 weeks

Previously obtained duodenal mucosal biopsies will be re-evaluated for eosinophils and mast cells

Gastric retentionup to 16 weeks

Gastric retention values will be captured from a previously completed 4-hour gastric emptying scintigraphy study
