Brief Summary

There is evidence for the use of a diet low in short chain fermentable carbohydrates (low FODMAP diet) in the management of functional gut symptoms, such as abdominal pain and bloating. However, the provision of advice on the low FODMAP diet can be challenging due to limited resources and the need for a dietitian with expertise in the low FODMAP diet. The aim of this study is to assess the feasibility in terms of recruitment and retention in planning a future trial. The purpose of the future trial will be to investigate the clinical and cost effectiveness, as well as the acceptability of different education methods of the low FODMAP diet for the treatment of IBS. To date, there are no studies on the implementation of the low FOMDAP diet using a mobile app or leaflets in the education of the low FODMAP diet. Therefore, a feasibility study design was chosen in order to obtain key data on recruitment and retention rates at each study group.

  Baseline (Day 0) and Follow-up visit (week 4)

• Appropriateness of the education methods received in each study group

  Baseline (Day 0) and Follow-up visit (week 4)

• Perceived fit of the education delivery methods within the NHS

  Follow-up visit (week 4)

• Willingness of participants being assigned to the study groups using a multiple choice questionnaire.

Study Arms (3)

Booklets

EXPERIMENTAL

Health education delivery method: Booklet. Patients will be given 2 leaflets on the low FOMDAP diet produced by the Department of Nutrition and Dietetic in Guy's \& St Thomas' NHS Foundation Trust, and the Diabetes and Nutritional Sciences Division at King's College London. These booklets have been produced by dietitians and are commonly used in clinical practice across the UK.

Other: Health education delivery methods

Mobile application

EXPERIMENTAL

Health education delivery method: Mobile application. Patients will be asked to download an application on their mobile phones or tablets. This application has been produced by dietitians from the Department of Nutrition and Dietetic in Guy's \& St Thomas' NHS Foundation Trust, and the Diabetes and Nutritional Sciences Division at King's College London.

Other: Health education delivery methods

One to one consultation with dietitian

ACTIVE COMPARATOR

Health education delivery method:One-to-one consultation with dietitian. Patients will attend a clinic visit for a one-to-one consultation with a dietitian. As per current clinical practice, the initial visit will last for 1 hour. During the visit, tailored information on the low FOMDAP diet will be given to match patients' individual needs. During the visit, either the leaflets (used in group 1) or the application (used in group 2) will be used to facilitate the visit. The choice of using the leaflets or the app during the visit will be based on the dietitian's judgment based on the patients' needs.
