Building on the success of the first edition, this new and expanded edition explores the complexities of inflammatory bowel disease (IBD) with an expanded focus on the viewpoint and experience of those living with IBD and the interface of clinical care and research opportunities. With cases of ulcerative colitis (UC) and Crohn’s disease (CD) rising worldwide, the need for informed, patient-centered care has never been greater. Despite their profound impact on daily life and healthcare systems, these conditions remain challenging to diagnose and treat. IBD nurses are increasingly recognised as key clinicians within the multidisciplinary team caring for people with IBD. Through experience and specialist knowledge, IBD nurses provide timely support, advice, and treatment for people living with this unpredictable condition. IBD nurses are also well placed to liaise with the wider team; developing patient centred services which best fit their local health framework. This updated manual brings together international expertise and practical insights to support nurses and clinicians in optimizing IBD management. Whether you’re a seasoned professional or looking to expand your expertise, this resource equips you with the knowledge and confidence to enhance care and improve outcomes for people living with IBD wherever in the world you work.
