A DIETA LOW FODMAP NA ANSIEDADE, DEPRESSÃO E QUALIDADE DE VIDA NA SÍNDROME DO INTESTINO IRRITÁVEL PELO CRITÉRIO ROMA IV.

Introduction: Irritable bowel syndrome is one of the main gastrointestinal disorders, with a significant impact on physical and mental wellbeing. Few studies address the effects of the low FODMAP diet on anxiety, depression, and quality of life, especially with the current diagnostic criteria, Rome IV. Objective: To evaluate the effects of the low FODMAP diet on anxiety, depression, and quality of life using the Rome IV criteria in IBS patients. Materials and methods: This is an integrative review. The search was carried out between April and June 2023 in four databases: PubMed, Cochrane Library, Virtual Health Library, and Scopus. The PICOS criteria was used for the construction of the guiding question, and the PRISMA-ScR for the selection of articles. Results and discussion: Four studies were selected, with the intervention of a low FODMAP diet, evaluating psychological (HADS) and gastrointestinal symptoms (IBS-SSS), and quality of life (IBSQOL). Dietary, psychological, and gastrointestinal factors are directly associated with quality of life. Conclusion: The interaction between the brain-gut-microbiota axis has a significant impact on IBS symptoms, including changes in bowel habits, abdominal pain, and psychiatric comorbidities. These alterations may explain the high prevalence of anxiety, depression, and a lower quality of life in IBS patients. The low FODMAP diet was found to be superior in reducing gastrointestinal and psychological symptoms and improving quality of life. The adherence and acceptability of the low FODMAP diet are important considerations when evaluating its clinical application. [ABSTRACT FROM AUTHOR]
