Objectives:
Diet is a recognised risk factor for inflammatory bowel disease (IBD) and a management strategy. Concerns persist regarding the adverse effects of restrictive diets, including nutritional deficiencies and selective eating. The impact of IBD on patients' beliefs and dietary choices remains poorly characterised, especially in different geographic contexts.
Aim:
To investigate dietary practices and beliefs in patients with IBD in Sweden, including variations by disease phenotype.
Methods:
A 42-item questionnaire on food choices and beliefs was distributed to all adult members of Sweden's largest IBD-patient organization.
Results:
Of the 2,193 individuals invited, 738 (34%) responded, (Crohn's disease (CD) 361 (49%); Ulcerative colitis (UC) 377 (51%)). IBD impacted thoughts about food in 71% (n = 521). A higher proportion of those with CD (254, 70%) than UC (231, 61%), reported changing their diet due to IBD (p = 0.009). A higher proportion of patients with CD (187, 52%), compared with UC (164, 43%), avoid certain foods in the belief that this can prevent flare-ups (p = 0.024). 42% (n = 311) of patients had not received dietary advice from health care providers, which was more common in UC (209, 55%) than CD (102, 28%), (p < 0.001).
Conclusions:
Beliefs about food and diet appear to influence dietary choices in IBD, many of whom report modifying their diet. This appears to be more pronounced among people with CD than UC, although the latter are less likely to receive dietary advice, highlighting potential disparities in access to dietary guidance.

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 colonic...

Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. 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 transmural...

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
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...
