Evaluation of Diet and Symptom Severity in Disorder of Gut-Brain Interaction

Background: Disorders of gut-brain interaction are chronic or recurrent symptoms originating in the gastrointestinal tract that cannot be substantiated by the results of standard clinical tests, such as radiologic studies, morphologies, or endoscopic examination. The diagnosis of these disorders is mainly based on symptoms and the standardized Rome IV criteria. These criteria classify functional disorders of the gastrointestinal tract according to anatomical location and define each disorder according to a set of symptoms. Methods: This study was conducted between October 2021 and February 2022. Participants in the study were patients of a gastroenterology outpatient clinic with a functional disease diagnosed by a gastroenterologist. A questionnaire was used to conduct the study, with questions regarding perceived functional discomforts of the gastrointestinal tract, dietary changes to alleviate discomforts, and frequency of consumption of various food groups. Results: Based on the study, statistical significance was demonstrated between the gender of the respondents and the severity of gastrointestinal complaints after the consumption of legumes and alcohol. The analysis performed confirmed the correlation between the age of the respondents and the severity of complaints when consuming raw vegetables and fruits, brassica vegetables, legumes, fried products, and spicy products. There was also a significant correlation between the body mass index (BMI) of the respondents and the severity of complaints after alcohol consumption. Conclusions: The results identify abdominal pain, bloating, and constipation as the most commonly reported gastrointestinal symptoms among participants. The association between the consumption of certain foods, such as milk and dairy products, as well as fried and fatty foods, and the severity of disorders of gut-brain interaction symptoms was confirmed. Despite this, the majority of respondents did not eliminate any food products to alleviate the discomfort.
