This prospective cohort study will evaluate the influence of psychoemotional status on the clinical course and quality of life of adult patients with functional dyspepsia and/or irritable bowel syndrome diagnosed according to Rome IV criteria. The study aims to assess the contribution of affective and somatoform disorders to quality of life and symptom burden in these patients. In participants with functional dyspepsia, the association of Helicobacter pylori status with psychoemotional status and quality of life will also be evaluated. Patients will complete validated questionnaires assessing quality of life, depression, anxiety, and somatization at baseline and again during follow-up after treatment. Clinical symptoms, pain severity, stool characteristics, and H. pylori status will also be assessed as applicable.
