Stroger Hospital of Cook Co, Chicago, IL Introduction: Functional dyspepsia (FD) is a common gastrointestinal disorder, affecting approximately 5 to 16 percent of people worldwide. Although dyspepsia can be a manifestation of Celiac disease(CD), most FD patients do not undergo serological screening for CD, and data on the prevalence of CD in dyspepsia patients is limited. This gap in research has prompted our investigation into the association between FD and celiac disease. Methods: We conducted a retrospective analysis using the 2017–2022 Nationwide Inpatient Sample (NIS). Demographic covariates, including sex, age and median household income quartile were considered. Clinical risk factors evaluated included anxiety, depression, Helicobacter pylori (H. Pylori), obesity, and smoking history. Associations are reported as odds ratios (OR) after conducting multivariable logistic regression, adjusting for these covariates and clinical risk factors. Results: Of the 36,146 patients with functional dyspepsia included in our study, 57% were female, 45% had anxiety or depression, 0.07% had a history of H. pylori infection, and 159(0.44%) had Celiac disease. Celiac emerged as a strong predictor of functional dyspepsia, with individuals carrying the diagnosis exhibiting nearly three times the odds of dyspeptic symptoms compared to those without celiac (OR 2.81; 95% CI 2.36–3.34; z = 11.69; P < 0.001). Psychiatric comorbidities also demonstrated significant associations: anxiety was linked to a 74% increase in odds (OR 1.74; 95% CI 1.69–1.79; z = 38.38; P < 0.001), and depression conferred a 26% increase (OR 1.26; 95% CI 1.23–1.30; z = 15.47; P < 0.001). A history of H. pylori infection was similarly associated with higher odds of functional dyspepsia (OR 2.93; 95% CI 1.84–4.65; z = 4.55; P < 0.001). Discussion: Our findings suggest that celiac disease is an independent risk factor for functional dyspepsia, alongside traditional factors like mood disorders and prior H. pylori infection. Further research is needed to explore these immunological links and the possible role of screening for celiac disease in patients with functional dyspepsia.
