Previous research has shown that adults with irritable bowel syndrome (IBS) who adopt a low FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) diet show an improvement in symptoms within 2 days. Would the low FODMAP diet have the same effect in childhood IBS? Does the gut microbiota predict the success of the diet in children who respond to this dietary intervention?…

Dysbiosis -- an abnormal gut microbiota -- is associated with several diseases, including irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Yet because of the great variation in gut microbiota composition between individuals, dysbiosis can be difficult to define. In a recent article published in Alimentary Pharmacology and Therapeutics, researchers introduce a new diagnostic test that they say can…

His main interests are gut functions in health and disease, including functional and inflammatory bowel disorders, the role of the gut microbiota, regulation of eating and food intake and its disorders, of nausea, vomiting and motion sickness, and the psychophysiology and neurobiology of the placebo response, with specific emphasis on age and gender contributions. He has published more than 170 original data paper in scientific, peer-reviewed journals, and more than 250 book chapters and review articles. He is board member/treasurer of the European Society of Neurogastroenterology and Motility and of the German Society of Neurogastroenterology and Motility, and has served as reviewer for many international journals and grant agencies.

Patients with irritable bowel syndrome (IBS) are a heterogenous group, and many report symptoms triggered by diet: most commonly wheat/grains, certain vegetables, milk products, fatty foods, spicy foods, coffee, and alcohol. A review published in The American Journal of Gastroenterology discusses the relationship between symptoms, diet, and microbiota in IBS. Authors summarize evidence on how diet and intestinal microbiota impact…

While a lot of research in gut microbiota is focused on the bacterial community, little research data is available on the microeukaryotic community. Knowledge about the role of the microeukaryotic community in the gut and its interaction with the bacterial community and its host is insufficient (Anderson et al., 2013). One of the commonly observed microeukaryotes is Blastocystis. There is ongoing…

(Berlin, October 16, 2013) Clinicians with gastrointestinal (GI) patients often wish – and are asked by their patients – to recommend specific probiotics. However, a clear and accessible evidence-based reference guide on the role and effectiveness of specific probiotics and their clinical use for managing particular lower gastrointestinal problems has been lacking so far. Now a new reference guide, which…
