Background/aims: Limited data is available in Saudi Arabia (SA) regarding the prevalence of functional dyspepsia (FD) symptoms and its subtypes, as defined by the ROME IV criteria. This study evaluated the burden of self-reported FD symptoms in the adult general population of SA and the current clinical practices.
Methods: A web-based national cross-sectional health survey of the general population of SA was conducted using the Rome IV Diagnostic Questionnaire for Functional Gastrointestinal Disorders in Adults with additional questions on the presence of symptoms compatible with functional heartburn (FH) and irritable bowel syndrome (IBS). The quality of life and somatization questionnaires were also included.
Results: Overall, 3,114 adults completed the questionnaire, but 303 (9.7%) were excluded due to inconsistent responses. Of the 2,811 consistent responders, 532 (18.3%) fulfilled the Rome IV criteria for FD symptoms. These were distributed into the FD subtypes as follows: 208 (7.4%) had postprandial distress syndrome, 228 (8.1%) had epigastric pain syndrome, and 96 (3.4%) had the overlapping variant. IBS-like symptoms were reported in 232 (44%) and FH in 102 (19%) 19% (102) of the subjects with functional dyspepsia. H. pylori-associated dyspepsia was reported by 25% (87/348). High somatization, lower quality of life scores, younger age, and female sex were associated more with the FD symptoms participants than those without. Approximately 1/5 respondents used over-the-counter medications to relieve the FD symptoms.
Conclusions: In this population-based survey, FD affected almost 1/5 of the responding adult population in SA, which was less than previously reported.
