Optimal management of inflammatory bowel disease (IBD) relies on a clear understanding and tailoring evidence based interventions by clinicians in partnership with patients. This article provides concise guidelines for the management of IBD in adults, based on the most up to date information at the time of writing and will be regularly updated. These guidelines were developed by the Saudi Ministry of Health in collaboration with the Saudi Gastroenterology Association and the Saudi Society of Clinical Pharmacy. After an extensive literature review, 78 evidence and expert opinion based recommendations for diagnosing and treating ulcerative colitis and Crohn's disease in adults were proposed and further refined by a voting process. The consensus guidelines include the finally agreed on statements with their level of evidence covering different aspects of IBD diagnosis and treatment.
