Which dietary component is often restricted in patients with inflammatory bowel disease (IBD)?

In patients with inflammatory bowel disease (IBD), dietary fiber is often restricted due to the nature of the condition. IBD, which includes Crohn's disease and ulcerative colitis, can lead to inflammation, strictures, or ulcerations in the gastrointestinal tract. During flare-ups of IBD, the bowel may become more sensitive and less able to handle certain types of food.

Dietary fiber, especially insoluble fiber found in whole grains, nuts, seeds, and some fruits and vegetables, can be difficult to digest and may exacerbate symptoms such as diarrhea, abdominal pain, and cramping. During acute phases, the gastrointestinal tract may need a low-fiber diet to reduce irritation and allow for healing.

While it’s important for IBD patients to get adequate nutrition, the emphasis is often placed on easing digestive load, which is why the restriction of dietary fiber is a common recommendation. In some cases, soluble fiber may still be included, but this is typically under careful guidance from healthcare professionals.
