Risk factors for functional dyspepsia, erosive and non-erosive gastroesophageal reflux disease: A cross-sectional study.

Background: Conflicting data exists regarding risk factors associated with Gastroesophageal Reflux Disease (GERD) and Functional Dyspepsia (FD). Few studies examine anxiety/depression in relation to GERD phenotypes (Esophagitis/EE, and Non-Erosive Reflux Disease/NERD), FD, and Rome-IV syndromes. Our aim was to evaluate the association between epidemiological factors and comorbidities with GERD phenotypes, FD, and Rome-IV syndromes, as well as their relationship with anxiety/depression.
