Do you have SIBO? Immunity and Your Gut

Do you suffer from digestive distress? Gas & bloating, belching & flatulence are sure signs that digestion is not functioning to par. Monitoring your bowel movements can also be an indicator that digestion has gone awry; diarrhea, constipation and the shape, size, color and smell of your stool can tell all. As well, disorders such as IBS, IBD, chronic illnesses and food intolerances can indicate your digestive system is out of balance.

If any of these symptoms ring true, then you may be suffering from Small Intestinal Bacterial Overgrowth (SIBO).

What is SIBO?

Small Intestinal Bacterial Overgrowth can occur when the ratio of good:bad bacteria in our gut becomes imbalanced. The proper ratio for good:bad should be approximately 85:15.However, many factors can upset this very delicate microbiome – a word used to describe the bacterial balance within the human body; which outnumbers our human microbes 10:1! SIBO occurs when the antagonistic bacteria, like Candida Albicans, which are usually kept in check by the “good” bacteria, flourish. Dysbiosis is another term used to describe an imbalance in this bacterial ratio.

Causes of Dysbiosis

Diets high in sugar, alcohol, gluten and refined carbohydrates, such as breads and pastas, can greatly contribute to SIBO as these bacteria feed on sugars.

Genetically Modified foods (GMOs), stress, pollution, chlorinated water, smoking and heavy metals, such as mercury exposure, have been shown to be contributing factors as well. Certain medications, such as antibiotics, the Birth Control Pill and Acid Blockers all contribute to an overgrowth in the antagonistic gut bacteria.

Digestion is a very intricate process. Our gut depends on proper nerve supply, muscle function, enzymes, bacteria, and neurotransmitters to properly digest food. While enzymes mainly break down our food, the nerves, muscles and neurotransmitters physically move the food through our digestive tract from the stomach to the small intestine and to the colon. Many factors can affect improper digestion:

  • Digestion begins in the brain; just think of your favorite food – what it smells like, how it looks and imagine the taste. What happens? You salivate and begin a chemical reaction in the body that readies the GI, like priming an engine.
  • Stress: The Nervous System regulates whether you will “Rest & Digest” (Parasympathetic) or be ready to “Fight & Flight” (Sympathetic) – there’s a catch, you cannot do both at the same time. If your body perceives stress, whatever the stress may be – finances, emotions, relationships, chronic illness, etc – you will not be able to digest. If you eat while you are stressed, more than likely you will be fermenting that meal instead of digesting it.
  • Chewing: Your stomach does not have teeth; food must be chewed, masticated and thoroughly mixed with saliva to begin carbohydrate breakdown.
  • Stomach Acid: Sufficient Hydrochloric Acid (HCl) is required to continue digestion. HCl is the only acid made by the body and is required in sufficient levels to activate all protein digestion and mineral absorption. Acid Blocking medication will shut this process down, allowing fermentation to continue.
  • Pancreas: Bicarbonate from the pancreas activates enzymes needed to digest food and also helps break down carbohydrates (sugars) sufficiently as well as proteins and fats.

How to test for SIBO

SIBO Breath Test
Breath testing measures the hydrogen (H) & methane (M) gas produced by bacteria in the SI that has diffused into the blood, then lungs, for expiration.  H & M are gases produced by bacteria, not by humans. The gas is graphed over the SI transit time of 2 or 3 hours & compared to baseline.  Patients drink a sugar solution of glucose or lactulose after a 1 or 2 day preparatory diet.  The diet removes much of the food that would feed the bacteria, allowing for a clear reaction to the sugar drink. Abnormal breath tests can also signify H pylori infection, carbohydrate malabsorption, pancreatic insufficiency and celiac disease.

Urine Indican Test:This functional medicine lab test will test the urine for by-products of yeast or bacteria in the small intestine.  This test is looking at quantitative and qualitative evaluation of urine for indicans and detection of an elevated level of serum d-lactic acid which will be present in SIBO.

Comprehensive Stool Test: This is also a functional medicine lab test looking at the flora of the large intestines. This test is determining levels of bacterial balance.

Symptomatology: Signs and symptoms are the body’s language; they are how the body speaks. Based on symptoms, information from the client’s health history and dietary intake we can quickly and accurately determine Root Causes.

What to do if you suspect SIBO…

There are natural therapies which can eliminate and rebalance the delicate balance of flora in the gut.

Recommendations for SIBO could include:

  • 4 R Strategy to digestive healing: Remove, Replace, Re-inoculate, Repair
  • Dietary: Simple Carbohydrate or Paleolithic Diet is most recommended
  • Herbal: Demulcent herbs, such as Marshmallow Root and Globe Artichoke, as examples
  • Supplementary: Anti-Infective compounds such as Garlic, Grapefruit Seed Extract or Pau D’Arco will remove the unfriendly bacteria
  • Nutrients: Healing formulas including Vitamins A, C, E and Zinc + L-Glutamine
  • Probiotics: in a therapeutic dose will help replenish and heal the intestinal lining

Working with a Holistic Practitioner to assess SIBO and implement a strategy to address the associated symptoms and to re balance the Small Intestinal Bacteria. A Holistic Nutritionists can guide you through the dietary changes as well as offer you a supplement protocol for lasting solutions.

  1. Hi Jennifer,

    Thank you for sharing this specific information to neutralize SIBO. After 4 months of misery, I was finally diagnosed with SIBO and I’m interested in the natural approach instead of Xifaxan. It’s hard to convince regular doctors to go that route especially when being treated at the birth of SIBO (Cedars Sinai).

    Do you happen to have specific amounts (doses) of each natural product you identified? I already do take garlic with food and occasionally drink Pau d’Arco tea. SO far, it doesn’t look like it is enough as pain under left rib and bloating is still there. Since these problems, I have also developed a white tongue which a pathologist confirms it is not candida but hairy tongue with a few depapilated spots. They think that part of it is due to bacteria.

    Thank you for your help – much appreciated!

  2. Hi Lexx, I am glad you found this article helpful! There are different forms of bacteria that can be influencing your SIBO. As a nutritional consultant I evaluate each person on an individual bases to determine what is the best protocol and approach. Addressing this health issue is a step by step process, it is also important for you to understand the underlying issues contributing to SIBO and how to prevent a re occurrence.
    I would be more than happy to set up an appointment with you in person or by Skype. Please contact me through Contact Jennifer Jennifer
