Our aim: To increase access to support delivered by FODMAP-trained Registered Dietitians in Wales.

Tested as part of the Bevan Exemplar Programme and being adopted across Wales.

Why this is important?

Studies show that the symptoms in over 75% of patients improve using the low FODMAP diet. NICE Clinical Guidelines (CG61, 2017) and the British Dietetic Association recommend the low FODMAP diet as an effective treatment for IBS if the advice is delivered by a FODMAP-trained Registered Dietitian.


Symptoms can be debilitating and affects quality of life (QOL), performance and productivity as well as sickness absence. IBS and related symptoms are also associated with considerable use of healthcare services and use of drugs and pharmaceutical medicines.


More recent work has shown that focusing on ‘fermentable carbohydrates’ (FODMAPs) improves clinical outcomes, especially when supported by a trained Dietitian with expertise and experience (Trott et al, 2019).

Increasing access to safe and effective care for people with IBS is a priority area and in this project, three Health Boards have introduced FODMAP-trained Registered Dietitian services reaching over 150 people during the initial period of adopting the Bevan Exemplar Innovation.


The teams participating in the Adopt and Spread Programme can provide insights into making the goal of supporting 450,000 people across Wales a reality.


With variations in the services developed across the Health Boards, there are now service delivery models which include a digital group-based service, collaboration between Gastroenterology and Primary Care, and joint service for Health Board staff and referred patients accessing FODMAP-trained Registered Dietitian services in Wales.

“Around 1 in 5 people experience IBS, this means that approximately 450,000 people in Wales suffer from IBS
