Inflammatory bowel disease

Lifestyle modifications


  • "Dietary management in IBD focuses on maximizing nutritional status,  maintaining adequate intake, and avoiding foods that can exacerbate  symptoms" (1)

  • Low FODMAP diet may improve symptoms in patients who have both irritable bowel syndrome and inflammatory bowel syndrome (1)

  • Lactose restriction may reduce symptoms of IBD in some people (1)

  • In remission: A diet composed of carbohydrates, fats and proteins. Limit intake of processed foods and artificial sweeteners (1)

  • With chronic stricturing: Low fiber intake (< 5g/day) (1)

  • Some low quality evidence show that plant based diets are associated with reduced risk, symptoms and prevention of relapse of IBD (3, 4, 5)


  • Smoking cessation reduces recurrence of Crohns disease (2)
