S1135 Prevalence and Perception of Post-Prandial Bloating in the United States Adult Population: Results From a Nationally Representative Survey

Introduction: Bloating is among the most common gastrointestinal symptoms, yet its burden and perception in the general population remain underexplored. Using a nationally representative United States sample, we aimed to characterize the beliefs and behaviors surrounding post-prandial bloating and identify demographic patterns that may influence care-seeking behavior. Methods: An online anonymous survey of nationally representative United States (US) adults aged ≥18 was conducted in March 2025. Respondents answered questions regarding their experience and beliefs about bloating, as well as actions taken or reasons for inaction among those who viewed bloating as a potential health issue. Chi-square tests were used to examine associations between age, gender, and reported perceptions or actions. Results: Among 2,000 respondents, 22.6% reported experiencing bloating within 2 hours of eating, with a higher prevalence among females compared to males (27.0% vs 18.1%; odds ratio 1.7, 95% confidence interval: 1.4-2.1). Patients older than 55 reported less bloating as compared to subjects 18-55 years (13.4% vs 28.0%, P < 0.01). Modest but significant differences were seen within four US regions. The majority of respondents with bloating (51.1%) believed that occasional bloating, gas, or stomach discomfort is normal, 29.7% considered it a sign of a deeper issue, and 19.2% were unsure. Similar proportions of males and females perceived bloating as normal (51.8% vs 50.6%, P = 0.6), with no significant regional differences. However, patients older than 55 were significantly less likely to consider bloating normal compared to younger groups (45.3% vs 54.6%, P < 0.01). Among those who believed such symptoms may indicate a deeper issue (n = 594) (75.3% reported they have addressed or would address the symptoms, with comparable rates among males and females (73.8% vs 76.9%, P = 0.5). Among those who would not address bloating, the primary barrier was uncertainty about appropriate treatment options (34.7%), followed by time constraints (26.5%). Financial limitations were cited by 23.8%, and 18.4% reported difficulty accessing gastrointestinal specialists. The results were comparable among males and females. Conclusion: Despite affecting >20% of the US adults, bloating is normalized or ignored in more than half of those affected. More than a quarter of individuals who recognize the potential seriousness of bloating still avoid seeking care. Findings highlight the need for public education and improved symptom recognition.
