Looking to pinpoint the cause of digestive distress and assess bacterial overgrowth?

This home breath kit measures gases that can indicate the presence of small intestinal bacterial overgrowth (SIBO). 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.

Herein is a kit containing a lactulose solution. Lactulose is a sugar that bacteria can digest (ferment). The fermentation of this sugar results in the production of hydrogen and/or methane gas. Our SIBO test provides the distinct advantage of measuring both gases, which, when present, may indicate SIBO:

Lactulose has the advantage of detecting bacterial overgrowth throughout the small intestine, including the lower end where it most commonly occurs. Humans cannot digest or absorb lactulose; only bacteria have the proper enzymes to do so. Since it is not absorbed, lactulose travels the entire length of the intestine, revealing SIBO at all portions of the intestine.2
