What it reveals
A breath test that measures hydrogen and methane levels after a lactulose or glucose substrate to help evaluate small-intestinal bacterial overgrowth.
What it measures
Screens for small intestinal bacterial or methanogen overgrowth (SIBO/IMO) as a driver of bloating and GI symptoms.
Breath Gas Analysis
Hydrogen and methane are produced when bacteria or methanogens ferment the test substrate; their pattern indicates overgrowth type and rough location.
Who this helps
- Bloating after meals
- Gas, diarrhea, or constipation
- Abdominal pain or distension
- Suspected small-intestinal bacterial overgrowth
