Trial Summary

What is the purpose of this trial?The pathophysiology of Irritable bowel syndrome (IBS) is multifactorial involving complex interplay of altered intestinal permeability, mucosal immune activation, visceral hypersensitivity and gut dysbiosis. Although the exact triggers for these pathological changes in IBS are not clear but diet might play an important role. In fact, several studies have reported improvement in gastrointestinal symptoms on a diet low in FODMAPs (LFD) in patients with IBS, specifically in diarrhea predominant IBS (IBS-D). However, the mechanism of action of LFD is not well understood.

Eligibility Criteria

This trial is for adults aged 18-65 with Irritable Bowel Syndrome (IBS), specifically those who often have diarrhea. Participants must have normal blood and stool test results, no C diff infections or parasites, and a certain score on an IBS symptom severity scale.

Inclusion Criteria

Tests for infections in your stool have to be normal.

I am between 18 and 65 years old.

Participant Groups

The study is testing the effects of a Low FODMAP Diet (LFD) on patients with IBS. The LFD aims to reduce symptoms by limiting foods that are high in certain sugars which can be hard to digest and may cause gut discomfort.
