What Is a SIBO Breath Test?
A SIBO test- small intestinal bacterial overgrowth is a simple, non-invasive breath test that measures the levels of hydrogen and methane gases produced by bacteria in your small intestine. These gases are exhaled after you ingest a specific sugar solution, allowing us to detect whether bacterial overgrowth is present.
