Small Intestine Bacterial Overgrowth has been associated with Irritable Bowel Syndrome and a range of other digestive disorders. While lower gut function is easily assessed using stool testing upper gut function can be more difficult to assess. We use breath testing to identify SIBO. This non-invasive test provides valuable information on upper gut function that helps us to structure an appropriate gut healing protocol using natural medicines and specific dietary interventions. The cost of SIBO Breath testing is approximately $130.00 and the turn around time is two weeks.
