Egypt183 participantsStarted 2024-06-01

Plain-language summary

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
