The Lactulose SIBO Breath Test is a non-invasive diagnostic procedure used to detect Small Intestinal Bacterial Overgrowth (SIBO), a condition where excessive bacteria are present in the small intestine. In this test, the patient consumes a lactulose solution, a type of sugar that humans cannot digest or absorb, but can be metabolized by bacteria. The patient then breathes into a device at regular intervals, usually every 15 to 20 minutes, over a period of two to three hours. The device measures the levels of hydrogen and methane in the breath, gases produced when bacteria ferment lactulose in the gut. Elevated levels of these gases at specific times during the test can indicate the presence of SIBO, providing valuable information for diagnosis and treatment planning.
