NCT02107625

Brief Summary

The purpose of this study is to to assess if the new diet with a low-FODMAP(Fermented Oligo-, Di-, Monosaccharides And Polyols) -content yields a milder symptom picture in IBS patients compared to traditionally dietary advice in IBS. The study also aim to investigate patients compliance to either dietary advices. Further, the investigators aim to find out if IBS patients with different symptoms are alleviated in different ways, to be able to individualize the dietary advices to result in a more optimal symptom relief in each patient in the future.

Outcome Measures

Primary Outcomes (1)

  • Symptom alleviation through the questionnaire IBS-SSS

    IBS-SSS i.e. the IBS Severity Scoring System. To assess the possible change of severity of IBS symptoms. The overall IBS score is calculated ranging from 0 to 500. A higher score implicates more severe symptom.

    4 weeks

Study Arms (2)

Diet A i.e. Low FODMAP diet

EXPERIMENTAL

The patients are thoroughly informed verbally and in writing how to eat according to the low FODMAP diet. The diet imply restrictions in carbohydrate intake and the patients need to follow a list with yes/no-foods for 4 weeks.

Behavioral: Diet A i.e. Low FODMAP diet

Diet B, i.e. Traditional IBS diet

EXPERIMENTAL

The patients are thoroughly informed verbally and in writing how to eat according to traditional IBS dietary advices. The diet imply adapting to regular dietary habit with meals 6 times a day, no to big meals, to chew food thoroughly, to peel fruits and vegetables, no carbonated beverages, no chewing gum, no soft drinks, no sugar-free candies, or cookies. Reduce spicy foods, coffee, alcohol, onion, pulses, and fatty foods. Keep strictly to the dietary advice for 4 weeks.

Behavioral: Diet B, i.e. Traditional IBS diet

Interventions
