SIBO Lactulose Breath Test For Small Intestinal Bacterial Overgrowth
This SIBO Lactulose Breath Test is designed for people experiencing ongoing digestive symptoms who want to investigate whether small intestinal bacterial overgrowth may be contributing to how they feel.
SIBO occurs when bacteria that normally live in the large intestine migrate into the small intestine, where they do not belong. This can interfere with digestion and nutrient absorption and may lead to a wide range of symptoms.
The lactulose breath test works by measuring hydrogen and methane gases in your breath after drinking a lactulose solution. These gases are produced when bacteria ferment the lactulose. Elevated or early rises in hydrogen or methane can indicate bacterial overgrowth in the small intestine.
Unlike standard stool testing, which looks at the large bowel, this breath test specifically assesses what is happening higher up in the digestive tract.
People often choose this test if they experience:
• Bloating, especially after meals
• Excessive gas or abdominal discomfort
• Constipation, diarrhoea or alternating bowel habits
• Feeling overly full quickly when eating
• Reflux or nausea
• Fatigue or brain fog linked to digestion
• Food sensitivities or intolerances
• Symptoms that persist despite dietary changes
SIBO is commonly associated with IBS type symptoms, slowed gut motility, previous food poisoning, stress, hormonal changes and conditions that affect digestion or the nervous system.
This is a non invasive, at home test. You collect breath samples at timed intervals after drinking the lactulose solution, then return them to the laboratory for analysis.
Clear step by step guidance is provided with your kit, including dietary preparation before testing to ensure accurate results.
What you receive:
You will receive your laboratory results showing hydrogen and methane gas levels over the testing period.
This is a results only service. No interpretation, recommendations or consultation are included. If you would like professional interpretation or personalised guidance, this can be arranged separately after you receive your results.
