"The Worst Test We Use All the Time - A Careful Review Of The Literature On Breath Testing For SIBO"

Clinical interest in small intestinal bacterial overgrowth (SIBO) has exploded over the past decade. Most SIBO practitioners consider breath testing to be an essential component of competent care. In the gastroenterological research community, breath testing has come under heavy criticism. Certainly no test is perfect but breath testing may exemplify this fact particularly well. While breath testing continues to be an essential part of many practices for SIBO diagnosis and management it is important to fully understand the limitations of the test in order to best utilize it in practice. Join us as we explore the literature on the worst test we use all the time.

Learning Objectives:

  • Explain the limitations of using breath tests for the diagnosis of SIBO compared to other alternatives.

  • Describe the specific issues with glucose-based breath tests for SIBO diagnosis.

  • Describe the specific issues with lactulose-based breath tests for SIBO diagnosis.

  • Critique the North American consensus document on breath testing for SIBO.
