In the young population, a persistent trend toward an increase in functional gastrointestinal disorders (FGIDs) is observed, with Generation Z representatives showing higher rates. The phenomenon of increased referrals of Generation Z individuals to gastroenterologists for FGIDs is indicative: these conditions account for nearly half of all initial consultations in this age group, driven by a combination of high medical awareness, a tendency toward self-diagnosis, and heightened sensitivity to somatic manifestations of psychoemotional stress. Emotional burnout, resulting from academic and professional workloads amid constant digital engagement, acts as a significant risk factor for reduced adaptive potential and deterioration in somatic and mental health indicators. In adolescents and young adults, multiple concomitant FGIDs are often identified, such as combined irritable bowel syndrome, functional dyspepsia, functional abdominal pain disorders, functional constipation, inflammatory bowel diseases, obesity, and others. FGIDs are frequently classified as disorders of gut-brain interaction (DGBI), reflecting the key role of bidirectional communication between the gut and the brain in their development and their impact on the comorbidity of psychological conditions. Accounting for the specific manifestations of comorbidity in the health status of adolescents and young adults with FGIDs is essential for developing effective treatment and preventive programs.
