SIBO stands for small intestine (or intestinal) bacterial overgrowth. The intestines are home to many millions and billions of microorganisms, but these organisms should be mostly limited to the large intestine. When bacteria accumulate and replicate in the small intestine beyond what is normally found there, we develop small intestine bacterial overgrowth. Intestinal bacteria normally digest and ferment the food we consume primarily in our large intestine, and provide us with all sorts of good things - like short chain fatty acids, vitamins, etc - in the process. In SIBO, the bacteria now ferment the food we consume in the small intestine, as well as the large intestine. This fermentation process produces gas – think yeast fermenting sugar to produce carbonated alcohol – and when fermented in the small intestine, this gas has nowhere to go! As the gas builds, it can cause pain, bloating or distention, and can contribute to diarrhea or constipation. These are also symptoms of irritable bowel syndrome or IBS. According to many studies, majority of individuals with the symptoms of IBS, also have SIBO.

Wait?! How do I know if I have Sibo?

Aside from symptoms that may point you or your health care provider towards considering a SIBO diagnosis, in order to have the appropriate information to make an accurate diagnosis you must get a breath test. The breath test measures Hydrogen and Methane levels in the blood that are byproducts of bacteria within the SI. I recommend the 3- hour Lactulose Breath Test. Contact your health care provider to order a test from one of the following labs:

    SIBO Testing Center  503-234-2037

    SIBO Center Lab (NUNM)  503-552-1931

    Pivotal Diagnostics  424-204-5853
    Neurovanna  651-342-0427

    Genova Diagnostics  800-522-4762

     Breath Trackers/Quin Tron  800-542-4448

    Aerodiagnostics   844-681-9449

    You can also order one directly (for yourself) through Direct Labs

There is an excess of information about SIBO out there on the internet. Instead of re-creating the wheel, I have decided to create a short list of resources that I trust to accurately inform you about SIBO and associated conditions.
