Better response to low FODMAP diet in disorders of gut–brain interaction patients with pronounced hydrogen response to a nutrient challenge test

Previous studies have shown a reduction of gastrointestinal symptoms in irritable bowel syndrome (IBS) patients following a low FODMAP diet (LFD). It remains unknown which disorders of gut-brain interaction (DGBI) patients would benefit most from LFD. We aimed to analyze LFD response regarding a preceding nutrient challenge test (NCT).Data of 110 consecutive DGBI patients undergoing NCT and LFD between August 2015 and August 2018 were analyzed...
