Diseases of the digestive system such as gastritis, functional gastrointestinal disorders and peptic ulcers are common throughout the world. Although these are generally not life-threatening conditions, they can significantly impair the quality of life of the sufferers. Gastritis is a condition characterized by inflammation of the gastric mucosa, and it can manifest itself in different forms, from mild and asymptomatic cases to severe forms associated with significant morbidity. Research goals: To determine the quality of life of gastritis sufferers. Respondents and methods: In the outpatient clinic of the Internal Medicine Service of the Pula General Hospital, a study was conducted with the aim of examining the impact of gastritis on the quality of life of patients, in which 100 subjects with a confirmed diagnosis of gastritis participated. The research was conducted using an anonymous Gastrointestinal Symptom Rating Scale (GSRS) questionnaire. A chisquare test was used to confirm a potential difference in responses between subjects among categorical variables. Absolute frequencies among answers with statistically significant differences in relation to socio-demographic characteristics are shown in tables and graphs. Results: Statistically significant differences were found (chi-square test) with regard to socio-demographic characteristics for one question from the survey, while for all remaining questions there were no statistically significant differences in answers. There is a statistically significant difference between the intensity of acid reflux with regard to the age of the subjects (p=0.007). Conclusion: Considering the results of the research, the hypothesis which assumes that patients with gastritis have a poor quality of life is not accepted as true.
