Experience of diet in patients with inflammatory bowel disease: A thematic synthesis of qualitative studies

Abstract

AbstractAimTo synthesise the dietary expesriences of patients with inflammatory bowel disease by reviewing relevant qualitative studies.BackgroundDiet plays a crucial role in the development and progression of inflammatory bowel disease (IBD). There is no specific diet that can be recommended for all patients. We conducted a synthesis of qualitative studies to gain a comprehensive understanding of the dietary management experience of patients with IBD, aiming to provide better dietary guidance in the future.DesignA qualitative synthesis was conducted following the Thomas and Harden method and reported following the ENTREQ statement.MethodsQualitative studies were systematically searched in five electronic databases: PubMed, PsycINFO, Embase, CINAHL, and Web of Science. There was no time limit for publication, and all database searches were up to 10 May, 2023. The Joanna Briggs Institute Qualitative Assessment and Review Instrument was utilised to appraise the quality of the included studies. Data for inclusion in articles were extracted and analysed using a thematic synthesis method.ResultsSix studies involving 119 patients were eventually included. The studies were conducted in six different countries. Four major themes were identified: the diet of patients with IBD is completely different from the normal one; manage symptoms and live with the disease by modifying diet; psychological adjustment to eating (be frustrated; worried and afraid; feel ashamed; growth and resilience); barriers and challenges (barriers from perceived social support; conflicts between diet and nutrition; challenges from food hedonism and cravings).ConclusionsPatients with IBD highlighted the distinction between their diet and the normal diet. Dietary modifications were used as a way to manage symptoms and live with the disease. In addition to physical symptoms, patients experienced diet‐related psychological changes. Dietary modifications in patients with IBD encounters difficulties and challenges, necessitating prompt guidance and intervention.(1) The implementation of dietary modifications in patients with IBD encounters numerous obstacles and complexities, necessitating prompt guidance and intervention.Patient or Public ContributionNo patient or public contribution.RegistrationThe protocol was registered with PROSPERO (CRD42023391545).
