Glucose breath test uncovers hydrogen- and methane-dominant subtypes of small bowel intestinal overgrowth in irritable bowel syndrome

2026-07-25

Abstract excerpt

<title>Abstract</title> <p> <bold>Background:</bold> Small intestinal bacterial overgrowth (SIBO) has been suggested in irritable bowel syndrome (IBS), but breath-test interpretation remains debated. We assessed hydrogen and methane responses during glucose breath testing (GBT) and whether an 80-minute window captured relevant pathological signals. <bold>Methods:</bold> We analysed 253 GBTs: 205 IBS patients...
