The SIBO Lactulose Breath Test is a non-invasive diagnostic procedure used to detect Small Intestinal Bacterial Overgrowth (SIBO). It measures hydrogen and methane gases produced by bacteria in the small intestine after consuming a lactulose solution. Lactulose, a non-absorbable sugar, is fermented by bacteria, leading to the production of these gases. The test involves collecting breath samples at regular intervals for several hours, allowing for a detailed analysis of gas patterns over time. This helps identify the presence and severity of bacterial overgrowth in the small bowel.
