Abstract: Objective: To conduct a systematic evaluation for qualitative studies on the experience of dietary restriction in patients with Inflammatory Bowel Disease (IBD), to inform the formulation of dietary management strategies for clinical healthcare professionals. Methods: Search qualitative studies on the restricted dietary experience of patients with IBD and integrate the results by the pooled integration method. Results: A total of 14 articles were included, 37 research results were refined, and 7 categories were formed, and 3 integrated results were integrated, which were the manifestations of patients' dietary restriction behaviors, the challenges encountered during dietary restrictions, and patients' self-management processes in dietary adjustment. Conclusion: The restricted dietary behaviors of IBD patients lack scientific basis and are associated with various negative experiences. Healthcare providers should improve the scientific validity of patients' dietary restrictions and focus on monitoring their psychological well-being and help patients facing the challenge.
