PG - e14181 LID - 10.1111/nmo.14181 [doi] AB - BACKGROUND: The low FODMAPs (fermentable oligo-, di-, monosaccharides, and polyols) diet improves lower gastrointestinal symptoms. Patients suffering from proton pump inhibitor (PPI) refractory gastroesophageal reflux disease (GERD) have limited treatment options. We investigated the efficacy of a low FODMAPs diet in patients with PPI refractory GERD. METHODS: This multicenter, randomized, open-label study compared the efficacy of a 4-week low FODMAPs diet and usual dietary advice (ie, low-fat diet and head of bed elevation) in patients with symptomatic PPI refractory GERD, defined by a Reflux Disease Questionnaire (RDQ) score >3 and abnormal pH-impedance monitoring on PPIs. The primary endpoint was the percentage of responders (RDQ
