Our SIBO breath collection kits come with either Glucose or Lactulose as a substrate so please select the option you want.
Small Intestinal Bacterial Overgrowth (SIBO) is a disorder of excessive bacterial growth in the small intestine. Unlike the large intestine, which is rich with bacteria, SIBO occurs when bacteria enter your normally almost completely sterile small intestine and begin to colonise. Patients with bacterial overgrowth typically develop symptoms including nausea, bloating, vomiting, diarrhoea, malnutrition, weight loss and malabsorption. Glucose is useful for distal SIBO and Lactulose for proximal SIBO. We recommend starting with Lactulose if this is the first time the test has been undertaken.
