Background/Objectives. Fatigue is defined as an overwhelming sense of tiredness, weakness, or ex-haustion, which can be physical, psychological, or a combination of both. Evidence suggests that fa-tigue is more prevalent among patients with inflammatory bowel disease (IBD) than in the general population. The aim of this study was to assess the prevalence of fatigue among Swedish IBD pa-tients. Another aim was to increase knowledge about factors that may contribute to fatigue, and strat-egies for managing fatigue. Methods. Swedish IBD patients were asked to complete the IBD Fatigue Scale. Analyses involved both a quantitative and a qualitative approach. Results. A total of 675 pa-tients participated in the study. Patients with active disease, continuous symptoms, extraintestinal manifestations, and impaired wellbeing had higher scores of fatigue. Four categories relating to fa-tigue were identified: (1) fatigue difficult to define and attribute, (2) fatigue arising from interacting bodily and psychosocial burdens, (3) managing a limited and fluctuating supply of energy, and (4) restoring energy through activity, support and recovery. Participants frequently described fatigue as arising from an interaction between disease activity, comorbid conditions, psychological distress, sleep problems, pain, and everyday life demands. Conclusions. Although fatigue was more severe among participants with active disease, continuous symptoms and impaired wellbeing, the free-text responses demonstrated that patients frequently perceived comorbidities, disturbed sleep, pain, psy-chological distress and demanding life circumstances as additional contributors. Management in-volved balancing rest and activity, planning limited energy, and drawing on supportive relationships and restorative environments. These findings support a holistic and person-centred approach in which fatigue is assessed beyond intestinal disease activity.
