Inflammatory bowel diseases (IBDs) are chronic immune-related diseases hypothesized to be a sequela of an interplay of genetic predisposition and environmental exposures. The global incidence of IBD is increasing, and more patients are exploring diet as a means to explain and treat their IBD. In fact, many patients strongly believe diet plays a fundamental role in the onset and management of their IBD. However, a significant proportion of patients report limited nutritional education from their provider, and providers report limited nutritional resources to aid in discussions with patients. This imbalance between supply and demand likely reflects the previous paucity of available literature characterizing the influence of diet in IBD. To address this gap in knowledge, we review the available literature to characterize the role of diet in the pathogenesis, exacerbation, and treatment of IBD. We aim to provide patients and providers with resources to better understand and discuss the role of diet in IBD, with the overall goal of improving patient care and satisfaction.

Despite limited data, the current literature suggests that DD is highly prevalent in active or quiescent IBD patients with ongoing defecatory symptoms and is responsive to biofeedback therapy. Although more studies are needed, DD should be considered in IBD patients with persistent defecatory symptoms.

OBJECTIVES: Despite the importance of adequate bowel cleansing prior to colonoscopy, national societies provide little guidance regarding which bowel preps are best tolerated and most effective; this reflects a lack of comparative effectiveness studies that directly evaluate available preps in a "real-world" setting. To address this gap, we conducted a prospective, naturalistic,

FI is prevalent in IBD patients without IPAA, and more common than non-IBD controls. Additional controlled studies are warranted to further identify effective therapeutic interventions for FI in IBD. 10.1093/ibd/izx109_video1izx109_Video_15760611117001.
