Find out if SIBO is behind your bloating.

The small intestine is hard to reach directly — it sits beyond the stomach, before the colon. Breath testing works around that: when bacteria in the small intestine ferment a test sugar, they produce hydrogen or methane, gases your body doesn't make on its own. Those gases absorb into your bloodstream and leave through your lungs, where timed breath samples can measure them. The pattern of gas over time is what a practitioner reads.

What are common symptoms associated with SIBO?

People with SIBO commonly report bloating — often worsening through the day — excess gas, abdominal discomfort, and changes in bowel habits. These symptoms overlap with many other digestive conditions, which is exactly why testing exists.

Can you test for SIBO at home?

Yes. At-home SIBO breath test kits let you complete the prep, drink the test solution, and collect timed breath samples at home, then mail them to a laboratory for analysis.

Is the SIBO breath test hard to do?

The collection itself is simple — breathing into tubes on a schedule. The part that requires care is the preparation: a restricted diet the day before and an overnight fast, following your kit's instructions exactly.

Who should consider SIBO testing?

That's a conversation for your healthcare provider — typically it comes up when digestive symptoms persist and other explanations have been considered.
