Diet components are important factors in pathogenesis of functional gastrointestinal disorders, especially in the irritable bowel syndrome. Fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) are a group of short chain, poorly absorbed and osmotically active carbohydrates, which can induce gastrointestinal symptoms because of rapid fermentation in different segments of the gut. Low FODMAP diet is a novel treatment option with proven efficacy in reducing symptoms of functional gastrointestinal disorders in adults. Conversely, although functional abdominal pain is a common health problem in children, the efficacy of a low FODMAP diet remains understudied in this population.
The aim of this study was to compare the effects of two diets: a low FODMAP diet and a diet based on standard dietary advice of the National Institute for Health and Care Excellence (NICE), on abdominal symptoms in children with functional abdominal pain.
