SIBO Home Breath Kit (Lactulose)
Small Intestinal Bacterial Overgrowth
Small Intestinal Bacterial Overgrowth (SIBO) occurs when intestinal bacteria overgrow in the small intestine. This overgrowth can lead to excess production of gas and bacterial metabolites, causing symptoms of bloating, flatulent, diarrhea, constipation, and cramping. Recent studies show that up to 78% of individuals diagnosed with irritable bowel syndrome (IBS) have SIBO.1 SIBO can also be present in those with gastrointestinal symptoms who do not have an IBS diagnosis. An at-home SIBO breath test that can help determine the cause of digestive distress.
Life Extension offers two options for SIBO testing, a kit containing a glucose solution, and a kit contacting a lactulose solution. Both glucose and lactulose are sugars that bacteria can digest (ferment). The fermentation of these sugars results in the production of hydrogen and/or methane gas. Both of our SIBO tests provide the distinct advantage of measuring both gases, which, when present, may indicate SIBO.
Difference between Glucose and Lactulose SIBO Breath Tests:
Which test should I take?
We suggest starting with the lactulose test because it examines the entire small intestine for SIBO. However, if the lactulose test is negative and a person is still experiencing symptoms, then we suggest following up with a glucose test since more bacteria can ferment glucose.3
