Impact of Short Duration FODMAP Restriction on Breath Gases and Gastrointestinal Symptoms.

ABSTRACT:

Introduction

Irritable bowel syndrome symptoms are thought to relate in part to the accumulation of luminal gases after ingestion of fermentable carbohydrates (i.e., fermentable oligosaccharides, disaccharides and monosaccharides, and polyols [FODMAPs]). To understand this relationship, participants monitored breath hydrogen (H 2 ) and methane (CH 4 ) levels using an at-home breath analysis device and recorded symptoms and meals in real-time using the associated app.

Methods

We studied 1,984 users from July 2021 to April 2025. Participants first completed a baseline week on their habitual diet, followed by a one-week low FODMAP diet (Reset), with continued tracking of meals, symptoms, and postprandial H 2 and CH 4 levels. Breath H 2 and CH 4 were measured in parts per millio
