Dr allison-SIBO summit

60% of IBS caused by SIBO

IBS is the most common gastrointestinal issue in the world, and studies have shown that 60% of IBS is caused by SIBO.

Do you want to know more about how to help your patients with this?

Dr Allison Siebecker, a world renowned SIBO specialist and pioneer of SIBO investigation, shares her insights with us.

Below is a little taste of Dr Siebecker’s talk.  To access your comprehensive 1.5 hour session with Dr Siebecker head to the SIBO Summit page.


  • SIBO is an overgrowth of normal bacteria in the small intestine, not pathogenic bacteria.  The issue is location, not bacterial type.
  • Digestion and absorption as a factor for the patient, due to bacteria competing with the host for food.
  • SIBO and the LPS relationship to mood disorders.

The Migrating Motor Complex

  • The migrating motor complex (MMC) is essential to normal healthy functioning of the small intestine. Dr Siebecker discusses how it is disrupted in SIBO.
  • The relationship of food poisoning, stress, drugs (such as commonly prescribed proton pump inhibitors), and antibiotics to MMC impairment.
  • Diseases that can cause impairment of the MMC, such as hypothyroidism and diabetes.
  • How important the quantity and integrity of the ICC cells is in the functioning of the MMC.

What causes SIBO?

Dr Siebecker further discusses underlying causes to SIBO, as well as risk factors, such as drugs, surgery, other diseases, lifestyle factors, injury, and genetics.  She also discusses various disorders and diseases associated with SIBO.

Further, Dr Siebecker discusses pathogenic bacteria and how their release of cytolethal distending toxin B (Cdt B) impairs the MMC through molecular mimicry with the vinculin protein in ICC cells.

The above is a brief summary of what Dr Siebecker discusses in the first half hour of her session. To access your full 1.5 hour session with Dr Siebecker, head to the SIBO Summit page.
