The Beneficial effect of dietary fiber on lower functional gastrointestinal disorders is well established, but the information about its therapeutic effect on the upper gastrointestinal disorders is insufficient. The aim of the study was to evaluate the effectiveness of dietary intervention using fiber-rich foods in patients with upper functional gastrointestinal disorders. The study involved 164 female patients with corresponding symptoms of functional dyspepsia or nonerosive reflux disease. The average amount of dietary fiber consumed per day was measured at the first visit using the nutritional history questionnaire. The functional state of the gastrointestinal tract was assessed with the clinical questionnaire. To supplement the target rate of dietary fiber to 40 grams per day, patients additionally received 20.2 ± 8.3 grams of fiber. For this purpose, with a regular diet, for breakfast was prescribed 100-400 g bread with a high fiber content or 60-150 g muesli. The clinical condition of patients was assessed initially and after initiation of dietary changes with intervals of two weeks, three times. Assessment of signs and symptoms of functional disorder revealed manifestation of diseases by the overlap of clinical symptoms from different locations. Optimization of the amount of dietary fiber in the diet of patients led to a significant improvement in clinical symptoms. Among the patients with nonerosive reflux disease frequency of esophageal symptoms declined considerably. The frequency of these complaints was estimated at 6 points for the basal condition and decreased to 1.8 after six weeks, in the group of patients with functional dyspepsia esophageal symptoms decreased from 6 to 2.4 points. Optimizing the daily intake of dietary fiber also led to a reduction in symptoms in the epigastric region. In the general group of patients, the initial score of 5.6 points decreased to 2.1 points, the decrease in other symptoms of dyspepsia was also significant. Along with a decrease in symptoms of the upper gastrointestinal tract, intestinal symptoms, in particular constipation, significantly declined, although the number of cases of diarrhea remained almost unchanged. These effects are explained by the influence of dietary fiber on transition time and motility of the intestine.
