Small Intestinal Bacterial Overgrowth

What is that?!?

You’re probably more familiar with the acronym, SIBO, pronounced “see-bo”.

I've seen this and have worked with several people in the last couple of years that have this diagnosis.

So what is it?

 Small Intestinal Bacterial Overgrowth is a condition characterized by an abnormal increase in bacteria in the small intestine. The symptoms that generally present with this condition are:

  • bloating, gas, and belching;

  • abdominal discomfort and/or pain;

  • nausea; and/or

  • can be associated with constipation or diarrhea.

It is typically diagnosed through a breath test. The hydrogen breath test is a fast, easy, and non-invasive method for testing for SIBO. By measuring the gases in the small intestine, a hydrogen breath test can determine if a patient is suffering from excess bacteria, and if so, to what extent.

Functional nutritionists, like myself, address SIBO through several key strategies:

Dietary Modifications

Implementing diets such as the Low FODMAP diet reduce fermentable carbohydrates that can feed bacteria in the small intestine, thereby alleviating symptoms associated with SIBO.

Nutritional Support

Recommending supplements that support gut health and reduce inflammation, such as probiotics, digestive enzymes, and nutrients like zinc and vitamin D, can help modulate the gut microbiome and improve overall digestive function. It is important to note, that in working with a professional, you get the proper recommendations for you.

Identifying Underlying Causes

Functional nutritionists work to identify and address underlying factors contributing to SIBO, such as impaired gut motility, anatomical abnormalities, or dietary habits that promote bacterial overgrowth.

Personalized Treatment Plans

Tailored treatment plans address individual needs and consider factors like microbiome diversity, immune function, and dietary tolerances to optimize outcomes and reduce symptom recurrence.

Overall, functional nutrition plays a crucial role in managing SIBO by addressing dietary factors, supporting gut health, and individualizing treatment plans to promote long-term digestive wellness.
