Long-term outcomes of the low FODMAP diet in patients with irritable bowel syndrome

The FODMAP diet is an efficacious treatment strategy for irritable bowel syndrome, but there remains limited data regarding long-term outcomes. This thesis has provided a comprehensive exploration of the long-term outcomes of education on a low FODMAP diet. Education on a FODMAP diet was effective and safe in most participants followed up for median 6 years, with two-thirds of participants reporting ongoing symptom control. Associations with disordered eating behaviours and risk of nutritional deficiencies were uncommon. Ongoing dietetic follow-up may help to identify patients at risk and allow early intervention strategies. No adverse metabolic or microbiome signals were noted.
