Background:
Functional dyspepsia is defined as at least a 3-month history of dyspepsia without structural explanation for the symptoms, and it accounts for most cases of dyspepsia. We designed this study to investigate functional dyspepsia among a Chinese population in Taiwan.
Methods:
Data from the medical records of 1,143 adult patients who underwent transoral upper endoscopy for symptoms of dyspepsia in our hospital were retrospectively analyzed between January 2008 and December 2008. Exclusion criteria were structural gastrointestinal and hepatobiliary abnormalities, prior gastric surgery or history of chronic medication use.
Results:
Patients were mainly in the third and fourth decades of life. More female patients were noted than male patients (ratio 2:1). The rate of Helicobacter pylori infection was 18.5%. The rate of response to therapeutic agents, including proton pump inhibitors, H2-receptor antagonists and prokinetic agents, ranged from 69% to 77% among all cases. Patients who underwent H. pylori eradication therapy (88.8%) had a significantly higher rate of symptom improvement than those without H. pylori infection (77.5%).
Conclusion:
Cases with functional dyspepsia have the characteristics of middle age, female predominance, a relatively lower H. pylori infection rate and a positive response to H. pylori eradication therapy.
