Abstract Background Anemia is a common systemic complication of inflammatory bowel disease (IBD) and is associated with worse disease outcomes, quality of life, and higher healthcare costs. Aims The purpose of this study was to determine how anemia severity impacts healthcare resource utilization and if treatment of anemia was associated with reduced utilization and costs. Methods Retrospective chart review of adult patients managed by gastroenterology between 2014 and 2018 at a tertiary referral center. Results The records of 1763 patients with IBD were included in the analysis, with 966 (55%) patients with CD, 799 (44%) with UC, and 18 (1%) with unspecified IBD. Of these patients, 951 (54%) had anemia. Patients with anemia had significantly more hospitalizations, increased length of stays, more ER, GI, and PCP visits, as well as higher costs when compared to patients with IBD without anemia. Patients with more severe anemia had more healthcare utilization and incurred even higher total costs. Treatment with IV or oral iron did not lower overall utilization or costs, when compared to patients with anemia who did not receive treatment (p
