41%- 48% of patients with inflammatory bowel disease (IBD), which is in remission, experience fatigue (1). Fatigue is associated with significant physical, emotional, psychological and social consequences (2). This can have wide-reaching implications for patients in their everyday lives, with issues around work productivity, academic achievement, close relationships, travel and leisure being profoundly affected. Based on data from the CCUK national lottery-funded research on fatigue, although 68% of responding IBD treating professionals felt that fatigue was adequately treatable less than half offer anything over and above checking the haemoglobin level and treat if low, with only around one third offering lifestyle related advice on diet, exercise and sleep (3). The CCUK funded research on fatigue and IBD led by Professor Christine Norton and Wladzia Czuber-Dochan has not only identified fatigue as a significant issue facing patients but has also developed an objective fatigue score to quantify it. Leading on from this the King's College team has studied the role of diet and exercise in fatigue.
