When dietary modification turns problematic in patients with esophageal conditions.

Background: Patients with chronic illness affecting the esophagus often modify their eating habits to manage symptoms. Although this begins as a protective strategy, anxiety around eating can become problematic, and lead to poor outcomes. We administered a survey to examine the factors associated with problematic eating behaviors in patients who have reflux and difficulty swallowing (esophageal dysphagia).

Methods: In total, 277 adult patients aged above 18 diagnosed with achalasia, eosinophilic esophagitis, and gastroesophageal reflux completed an online survey: (1) demographic and disease information; (2) reflux and dysphagia severity (3) eating behaviors, as measured by a study-specific, modified version of the Eating Disorder Questionnaire (EDE-Q) for patients with esophageal conditions; and (4) Food related quality of life (FRQOL). Descriptive statistics, one-way ANOVA, and Pearson's correlations evaluated the sample data and a hierarchical linear regression evaluated predictors of problematic eating behaviors.

Key results: Problematic eating behaviors were associated with reflux severity, dysphagia severity, symptom anxiety, and hypervigilance, and negatively associated with FRQOL. While reflux and dysphagia severity predicted greater problematic eating, symptom anxiety explained more of these behaviors. Although hypervigilance and anxiety also predicted poorer FRQOL, problematic eating was the largest predictor.

Conclusion & inferences: Problematic eating behaviors are associated with increased symptom severity and symptom anxiety, and diminished FRQoL. Symptom anxiety, rather than symptom severity, appears to be a driving factor in problematic eating behaviors. Interventions aimed at diminishing symptom anxiety may be useful in reducing problematic eating behaviors in patients with gastrointestinal symptoms.
