Background
Gastroesophageal reflux disease (GERD) and dyspepsia are highly prevalent in the general population with significant symptom overlap, while the interaction between both remains poorly understood.
Aim
To examine whether GERD overlapping dyspepsia would have an impact on clinical and psychological features as compared with GERD alone.
Methods
We performed a cross-sectional study in a GERD cohort (n = 868) that was previously recruited from a population-based GERD survey (n = 2752). We compared the clinical and psychological factors between patients with and without dyspeptic symptoms “epigastric pain or burning.” All participants were evaluated with Reflux Disease Questionnaire score, Pittsburgh Sleep Quality Index score, Taiwanese Depression Questionnaire score, and State-Trait Anxiety Inventory score. Endoscopic findings were classified according to the Los Angeles classification.
Results
Among the GERD population, 107 subjects had overlapping “epigastric pain or burning” (GERD-D), and 761 did not have these symptoms (GERD alone). GERD-D subjects had more severe GERD symptoms and were more often associated with irritable bowel syndrome (IBS) (OR 3.54, 95% CI 1.92–6.52) as compared subjects with GERD alone. In addition, GERD-D subjects had lower quality of sleep (OR 1.11, 95% CI 1.01–1.21), higher depression (OR 1.06, 95% CI 1.02–1.10), lower blood pressure (OR 0.45, 95% CI 0.22–0.95), and higher serum total cholesterol levels (OR 2.78, 95% CI 1.36–5.67) than GERD alone.
Conclusions
GERD-D subjects are characterized with worsening clinical symptoms as well as higher psychosocial, IBS, and metabolic comorbidities, but less erosive esophagitis. Our results indicate that clinical awareness of such overlapping condition would help optimize the management of GERD in clinical practice.
