GIT Breath Test (S.I.B.O) – All Sugars Lactulose/Glucose/Fructose

SIBO breath testing with Lactulose, Fructose, and Glucose substrates is a non-invasive tool used to identify small intestinal bacterial overgrowth (SIBO), a condition where excessive bacteria grow in the small intestine, leading to digestive symptoms. This test measures the levels of hydrogen and methane in your breath after ingesting different substrates. Lactulose, Fructose, and Glucose substrates are commonly used to evaluate how your digestive system reacts to various sugars, which can trigger bacterial fermentation and result in the production of gas. Elevated levels of hydrogen or methane in the breath indicate bacterial overgrowth and can help specify the type of SIBO you may have.

Lactulose is a sugar that is not absorbed by the body, and it helps identify SIBO in the small intestine. Fructose is a sugar found in many fruits, and its testing can reveal specific types of bacterial imbalances. Glucose, a simple sugar, is used to assess bacterial overgrowth in the upper small intestine. By using all three substrates, the test provides a comprehensive evaluation of bacterial activity throughout the small intestine, offering a more comprehensive and detailed diagnosis. This breath test is particularly helpful for individuals experiencing symptoms like bloating, diarrhoea, constipation, abdominal discomfort, and fatigue, which may be linked to SIBO. By identifying the presence and type of SIBO, healthcare providers can offer targeted treatment options, such as dietary changes or antibiotics, to improve digestive health and overall wellbeing.
