Irritable bowel syndrome (IBS) is a common disorder of gut-brain interaction, characterized by chronic abdominal pain and altered bowel habits. A low-FODMAP diet (LFD), which restricts specific types of fermentable carbohydrates, significantly reduces IBS symptoms and improves quality of life (QoL). Objectives: To evaluate the short- and long-term effects of LFD on improving symptom severity and the quality of life of IBS patients attending the family medicine outpatient clinic, and to assess LFD acceptability and adherence of IBS patients. Methods: Randomized control trial conducted on (123 patients) with IBS attending outpatient clinic of family medicine at Tenth of Ramadan University Hospital from 1st of June 2024 to the end of June 2025. An intervention group (No=93) received patient-centered education about LFD, and a control group (No.=90). Participants in both groups underwent an assessment of their BMI, Irritable Bowel Syndrome- Severity Scoring System (IBS-SSS), and irritable bowel syndrome-Quality of Life Measure (IBS-QOL) preintervention during the first visit and reassessed post-intervention after one, three, and six months. Additionally, Patients in the intervention group were assessed for the FODMAP Adherence Report Scale (FARS), LFD acceptability questionnaire, and Food-related QOL questionnaire at one, three-, and six-month post-intervention phases.
