Does the low FODMAP diet improve symptoms of radiation-induced enteropathy? A pilot study

AbstractRationale: Patients with radiation-induced enteropathy (RE) after cancer treatment show similar symptoms as patients with irritable bowel syndrome (IBS). The low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet (LFD) is a widespread management strategy for IBS. We aimed to investigate if there may be a positive effect of LFD on symptoms and health-related quality of life (HRQOL) in patients with RE.Methods: In an open non-controlled pilot study, 11 patients (all female) with RE-related IBS symptoms were recruited largely based on own initiative. All followed LFD for four weeks. IBS Severity Scoring System (IBS-SSS) and IBS Symptom Questionnaire (IBS-SQ) were used to assess symptoms. Short Form Nepean Dyspepsia Index (SF-NDI) and 12-item Short Form Health Survey (SF-12) evaluated HRQOL. A three day food record was used to estimate baseline intake of FODMAPs and to reveal dietary changes.Results: FODMAP intake was successfully reduced, although LFD was found a ...
