In the present study we report on changes in irritable bowel syndrome-severity scoring system(IBS-SSS)and irritable bowel syndrome-quality of life(IBS-QoL)in 19 IBS patients,aged 18 to 74 years(F/M:14/5),during 12 wk ...In the present study we report on changes in irritable bowel syndrome-severity scoring system(IBS-SSS)and irritable bowel syndrome-quality of life(IBS-QoL)in 19 IBS patients,aged 18 to 74 years(F/M:14/5),during 12 wk registering their symptoms on the webapplication(www.ibs.constant-care.dk).During a control period of the first 6-wk patients were asked to register their IBS-SSS and IBS-QoL on the web-application weekly without receiving any intervention.Thereafter,low fermentable oligo-,di-,mono-saccharides and polyols(FODMAP)diet(LFD)was introduced for the next6 wk while continuing the registration.Though a small sample size a significant improvement in disease activity(IBS-SSS)was observed during both the control period,median:278(range:122-377),P=0.02,and subsequently during the LFD period,median:151(range:29-334),P<0.01.The IBS-QoL solely changed significantly during the LFD period,median:67(37-120),P<0.01.The significant reduction in disease activity during the control period shows a positive effect of the web-application on IBS symptoms when presented as a"traffic light".However adding the diet reduced IBSSSS to<150,inactive to mild symptoms.In the future results from larger scale trials are awaited.展开更多
