A. Dietary modification in Ulcerative Colitis also depends on the severity of the condition. In some cases, doctors temporarily ask patients to eat low-fibre food to find some relief from the chronic pain and the urge to empty the bowel frequently.

Furthermore, whole fruits and vegetables act as a source of vitamins and antioxidants, which may help in Ulcerative Colitis.
