The article presents an analysis of the results of dynamic observation of a group of servicemen with dyspepsia without erosive and ulcerative lesions (n = 143) during the period of compulsory military service. As a result of dynamic observation for 8 to 18 months, the frequency of relapses of dyspepsia (excluding the results of eradication of Helicobacter pylori – H. pylori infection) was 27.3 % (95 % CI 20.6–35.1), the duration of remission after the first manifestation symptoms – 92 days (58–154) Me (LQ-UQ), duration of relapse – 12 days (11–17) Me (LQ-UQ). In H. pylori-negative and H. pylori-positive servicemen who did not receive eradication therapy, the frequency of relapses of dyspepsia did not differ (26.8 % versus 23.7 %; χ2 = 0.17, p = 0.68). During the observation period, diseases were detected or developed: in 1.4 % (95 % CI 0.4–4.9) – erosion of the mucous membrane (МM) of the duodenal bulb, in 1.4 % – esophagitis st. A and B, 2.8 % (95 % CI 1.1–6.9) are not associated with the digestive system. When examining for recurrence of dyspepsia symptoms, new morphological cases were diagnosed – 1 (0.7 %) atrophy, 2 (1.4 %) – intestinal metaplasia, 1 (0.7 %) – low-grade dysplasia (all cases with localization in the antrum section of the stomach ММ). The results of the study served as the basis for the development of an algorithm for diagnosing diseases of the upper gastrointestinal tract (GIT) in case of dyspepsia in conscripts at the stages of medical care in the Armed Forces of the Republic of Belarus.
