SIBO is a condition that affects the small bowel and occurs when bacteria that are normally in the large intestine overgrow in the small intestine. Symptoms commonly include bloating, belching and gas, abdominal pain, diarrhea, constipation or a mixture of the two. Nausea and heartburn are also common. SIBO is the most common reason people experience IBS symptoms. SIBO is diagnosed using breath testing that reveals elevated hydrogen or methane gases or in some cases both. Some common risk factors for SIBO include food poisoning, abdominal surgery, traumatic brain injury, Crohn’s disease and other conditions that alter Ileocecal Valve function.To properly diagnose Small Intestinal Bacterial Overgrowth it is important for testing to be performed by a reputable lab that measures hydrogen, methane, and carbon dioxide gases. It is also important that a proper preparation diet is followed and that the proper substrate is used in the proper quantity. Either lactulose or glucose or both are commonly used for breath testing.
The test is typically done at home with a kit that our office provides. The patient drinks the lactulose or glucose liquid and breathes into vials ideally every 20 minutes for the next 3 hours and then send the kit to the lab.
