Background: Helicobacter pylori infection occurs worldwide, affecting more than half of the world population. The clear aetiology of dyspeptic symptoms is still unclear but helicobacter infection is main contributing factor for it we investigated Helicobacter pylori prevalence in dyspepsia. Methods: 100 cases of dyspepsia attended Adichunchanagiri hospital and research center, studied over a period of 18 months (January 2020 to June 2021), were subjected to upper gastrointestinal endoscopy, during which 4 biopsies, two each from the antrum and the pathological areas were taken. Two biopsy specimens, one of the antral area and the other of the pathological finding were immediately inoculated into freshly prepared urea broth containing phenol red as the indicator. Positive test for Helicobacter pylori was indicated by change in colour of the medium from yellow to pink or red. The other two biopsy specimens were sent for routine histopathology. The case was taken as Helicobacter pylori positive when the rapid urease test and/or histopathological examination were positive. Results: Out of 100 dyspeptic patients who were included in the study, there were 65 male patients and 35 female patients. In which 71 patients were found to have been infected with Helicobacter pylori (71%). Conclusion: In this study, we found that in Dyspepsia the Helicobacter pylori was consistently associated and its well proved with various studies done in past and present. Thus we conclude Helicobacter pylori infection definitely have role in the aetiopathogenesis of dyspepsia. Keywords: Giemsa; Helicobacter Pylori; Peptic ulcer disease; Urease; Ulcerative dyspepsia.
