Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 to 70 who have been diagnosed with Irritable Bowel Syndrome according to the Rome IV criteria.

Probably not a fit

Patients with major psychiatric disorders or those who have experienced significant psychosomatic gastrointestinal issues may not benefit from this study.

What this trial studies

This study aims to assess the effectiveness of the DOMINO diet application in managing Irritable Bowel Syndrome (IBS) among patients in a tertiary care setting. Participants will utilize the app to follow a strict low FODMAP diet, which is designed to alleviate IBS symptoms. The study will also evaluate the response rate of patients who do not initially respond to the DOMINO app by subsequently implementing the low FODMAP diet. The research will involve dietary interventions and will collect data on symptom relief and overall patient satisfaction.

Why it matters

Potential benefit: If successful, this study could provide a valuable digital tool for IBS patients to manage their symptoms more effectively.

How similar studies have gone: Previous studies have shown promise in using dietary interventions like the low FODMAP diet for IBS, suggesting that this approach may be effective.
