Abstract

Background: Disorders of Gut-Brain Interaction (DGBI) affect 40% of the general population and are associated with substantial health impairment. Medical students reportedly have among the highest rates of DGBI, although data is mainly from Asia and Africa. We addressed this issue within a UK-based university.

Methods: An online survey was completed by 378 of 1621 medical students. Demographics, medical history, and gastrointestinal symptoms were collected, the latter using a modified Rome IV questionnaire to determine the presence of DGBI symptoms over the last 3 months. Additional validated questionnaires screened for somatization, psychological distress, eating disorders, quality of life, and burnout.

Results: DGBI were present in 76% (n=289/378), of which two-of-three had multiple affected sites. The most frequent DGBI were gastroduodenal (57%), followed by bowel (49%), esophageal (29%), and anorectal (26%) disorders. Approximately 50% of students with DGBI experienced painful gastrointestinal symptoms at least one day/week. Students with DGBI, compared to those without, had significantly higher anxiety and depression scores, increased somatic symptom reporting, reduced mental and physical quality of life, poorer eating habits, and more frequent medication use (p-values, all<0.05). They were also at significantly higher risk of burnout, through study exhaustion and disengagement. The greatest health impairment was seen in those with multiple, painful, DGBI. Only 23% and 5% of students with DGBI had consulted a primary care provider and gastroenterologist, respectively.

Conclusion: Medical students commonly experience DGBI and associated health burden, yet infrequently seek help. Greater awareness may lead to increased support, improved health, and better study engagement.

The image is a Venn diagram illustrating the overlap between different anatomical regions affected by Disorders of Gut Brain Interaction (DGBI) among medical students. There are three circles representing oesophageal disorders (blue), gastroduodenal disorders (green), and bowel disorders (yellow), with varying degrees of overlap. The total number of students surveyed is 289, with 110 (38%) having oesophageal disorders, 214 (74%) with gastroduodenal, and 184 (64%) with bowel disorders. Central to the diagram is a shared intersection showing 13% of students with conditions affecting all three regions. Surrounding this are sections where two regions overlap, indicating smaller percentages of students with disorders in two regions. Each circle also contains areas with no overlap, specifying the proportion of students with conditions unique to that anatomical region.
