Hydrogen breath test for irritable bowel syndrome. Lansdale: HAYES, Inc.. Directory Publication. 2012
The hydrogen breath test (HBT) involves obtaining breath samples before and at timed intervals after ingesting a carbohydrate substrate and analyzing these samples for hydrogen (H2) content. Intestinal bacteria ferment the carbohydrate, producing the only source of bodily H2, which is expelled in the breath. The pattern and degree of expelled H2 may indicate the presence of particular gastrointestinal (GI) disorders. Irritable bowel syndrome (IBS) is a chronic GI disorder that is diagnosed only by symptoms but shares symptoms with other GI conditions. In patients with IBS, the HBT is performed to identify GI conditions that may be responsible for symptoms and may be treatable, potentially providing symptom relief.
