Updated Guidelines for Assessing and Treating SIBO


Small intestine bacterial overgrowth, or SIBO, is a condition in which the small bowel is colonized by microbes normally found in the large intestine. This common gastrointestinal disorder is characterized by maldigestion and malabsorption of critical nutrients.

SIBO presents with IBS-like symptoms (i.e. abdominal bloating and gas, changes in bowel habits, abdominal pain, nausea and vomiting) which are intensified postprandially. The gold standard of SIBO diagnosis is small bowel fluid aspiration followed by culture. Due to the invasive nature of this procedure and the many shortcomings, assessing breath gases following a challenge drink has been widely accepted. Due to the increasing literature and medical attention, new SIBO guidelines have been established for clinicians and researchers to help standardize testing and interpretation of results.

In this webinar, Dr. Stubbe will review the new SIBO guidelines and discuss the latest option of a 2- and 3-hour breath test offered at Genova Diagnostics. In addition, interventions involving diet, digestive support, probiotics, and antimicrobials will be discussed.

In this webinar you will learn:

  1. Common underlying causes of SIBO
  2. Current guidelines as it relates to testing and interpretation of the SIBO breath test
  3. Interventions used to treat and prevent SIBO
