Prevalence of Functional Dyspepsia in a Rural Community of Bangladesh : A Cross Sectional Study
An observational study of Functional Dyspepsia, run by Bangladesh Medical University at 1 site in Bangladesh.
Trial summary
Functional dyspepsia (FD) is a common gastrointestinal disorder with an important impact on quality of life. There is a paucity of updated data on the prevalence of FD in rural areas of Bangladesh. The present study will be carried out to find the prevalence of FD in a community in rural Bangladesh. Read more about this study

About this study
Official title: Prevalence of Functional Dyspepsia in Rural Community of Bangladesh: A Cross Sectional Study
Functional dyspepsia (FD) is a common gastrointestinal disorder with an important impact on quality of life. There is a paucity of updated data on the prevalence of FD in rural areas of Bangladesh. The present study will be carried out to find the prevalence of FD in a community in rural Bangladesh. It also assesses potential risk factors. Eligible participants will first be evaluated for symptoms by a clinical interview using the standardized Rome IV functional dyspepsia questionnaire. Those who meet Rome IV criteria will then have an upper gastrointestinal endoscopy to exclude underlying organic diseases to establish a definitive diagnosis. Eventually patients with normal endoscopic findings will be diagnosed as having functional dyspepsia. This allows the accurate calculation of disease prevalence. Researchers will gather demographic information, lifestyle habits, and dietary patterns. The results will give important baseline data on rural FD burdens. Such data can inform community health care interventions.

Questions about this trial
What is this clinical trial studying?
An observational study of Functional Dyspepsia, run by Bangladesh Medical University at 1 site in Bangladesh.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 10 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Bangladesh. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Jabadur Rahman Peom (+8801925311811, peom1994@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Prevalence of Functional Dyspepsia in a Rural Community of Bangladesh (time frame: From January 2026 to December 2026). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07694778, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jul 2026.
