Small Intestinal Bacterial Overgrowth (SIBO) is an overgrowth of bacteria in the small intestine. Symptoms such as bloating, abdominal pain and discomfort, malabsorption, nausea, constipation, or diarrhea overlap with several common GI complaints. SIBO affects millions of people worldwide. Many providers are not aware of SIBO or the guidelines that standardize testing and diagnosing.

The Final Scholarly Project (FSP) was based on a literature review that discovered evidence-based literature on SIBO testing strategies such as gut aspirate and culture, clinical symptom presentation, breath testing, nutrient challenge test, and scintigraphy with either lactulose or hydrogen breath testing. To implement the project, pre-educational chart review was conducted in a Functional Medicine Practice where Advanced Practice Nurse’s (APRN) treat patients with SIBO, IBS, and common gastrointestinal (GI) complaints. The pre-educational chart review looked to determine if SIBO testing and diagnosing guidelines were being used in practice. An educational program outlining the evidence-based literature reviewed on SIBO testing and diagnosing and the results of the pre- educational program chart review was collated and shared with the APRN’s at the Functional Medicine Practice. A post-educational chart review was conducted four weeks later to measure compliance with the standards.

The FSP aimed to create SIBO awareness through education and determine if SIBO testing and diagnosing guidelines were being incorporated into practice. The APRN’s in a Functional Medicine Practice were receptive to the educational program offered and interested in implementing SIBO testing guidelines into their practice.
