Background And Aims:
The present study investigated the prevalence and severity of fatigue in patients with newly diagnosed and untreated ulcerative colitis (UC) and Crohn's disease (CD) and examined relevant disease variables that may influence the severity of fatigue.
Methods:
Eighty-one patients with inflammatory bowel disease (IBD) (60 with UC and 21 with CD) were assessed for fatigue using two fatigue instruments: the Fatigue Severity Scale (FSS) and a fatigue visual analogue scale (fVAS). Cut-off for fatigue was defined as ≥4 for FSS and ≥50 for fVAS. Results were compared with fatigue scores from age-and gender-matched healthy individuals. Disease activity was assessed by symptom scores using the Mayo score in UC patients and the Harvey-Bradshaw index for CD patients, as well as C-reactive protein (CRP) and faecal calprotectin.
Results:
The prevalence of fatigue based on FSS and fVAS was 47 and 42%, respectively, in UC and 62 and 48% in CD. In multivariate regression models, disease activity markers were not associated with fatigue, while a significant relationship was found with age and depression for both fatigue measures.
Conclusions:
Close to 50% of patients with IBD reported fatigue at the time of diagnosis. In newly diagnosed patients with active disease, the severity of fatigue was not associated with measures of disease activity.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
