Understand and Overcome SIBO

Does your stomach constantly feel irritated, bloated, painful, or nauseated? Are you tired of constipation and gas? Perhaps you have already been diagnosed with SIBO, or you’re just suspicious that this may be the cause of your discomfort. In this article, I (Dr. Deglmann) hope to shed some light on what SIBO is, what the symptoms are, what the most common causes are so you can understand and overcome SIBO. I’ll also go over how my at-home, online Gut Health and SIBO Program can help you. 

What is SIBO?

Small intestinal bacterial overgrowth (SIBO) is a condition that occurs when bacteria that are supposed to stay in the large intestine/colon begin to travel up into the small intestine. This bacteria then begins to feed on the food in our small intestine creating a fermentation process that can lead to significant symptoms. 

Some common symptoms of SIBO include:

    • Gas/bloating
    • Constipation or diarrhea
    • Acid reflux/heartburn/GERD
    • Nausea
    • Abdominal pain and/or cramping
    • Food sensitivities
    • Irritable bowel syndrome (IBS)
    • And more

SIBO impacts your quality of life

SIBO may not be life-threatening, but it does threaten your quality of life and can lead to other problems. If left unaddressed, SIBO can also contribute to leaky gut or intestinal permeability that can create chronic inflammation. That inflammation can potentially lead to other chronic conditions, including autoimmunity. 

This condition has become a widespread problem of epic proportions. In the US alone, it is estimated that 84% of those with IBS also suffer from SIBO. This means that at least 36 million Americans have SIBO. We know that number is even greater because there are many suffering from SIBO who go undiagnosed.

What causes SIBO?

With the prevalence of SIBO, you may be wondering how it develops in the first place. SIBO occurs when there is an overabundance of commensal bacteria from the colon present in the small intestine. It is largely overlooked and more prevalent than previously thought.

SIBO remains an area of research, but it is understood that dysbiosis and motility are key components. Such dysbiosis of the small intestine can be attributable to:

    • Low stomach acid
    • Medications such as antibiotics
    • Alcohol consumption
    • Chronic stress
    • Processed diet

What can be done to help SIBO? 

The health of the small intestines relies on the state of your gut bacteria. It needs a balanced microbiome. Prebiotics, probiotics and immunoglobulins can contribute to that balance by having a positive influence on the intestinal environment, including pH, organism diversity, and immune signaling. Probiotics have been extensively studied and are characterized as having broad GI and immune benefits.

Probiotic benefits include:

    • Increasing the population of healthy bacteria following microflora imbalance
    • Supporting healthy bowel function
    • Increasing the production of short-chain fatty acids, which provide energy to the cells of the intestinal lining
    • Strengthening the gut-immune barrier by promoting a healthy gut mucosa
    • Aiding in digestive health
    • And enhancing the detoxification of harmful compounds

Because probiotics are live organisms, it’s important to take note of their expiration date. You want them to be precisely delivered to the intestinal tract to have maximum benefit. 

Bacillus spores

Bacillus spores can transition between a dormant and an active form, depending on the environment. They remain dormant in harsh environments until they reach more favorable environments like the human gastrointestinal tract. 

In its dormant spore form, Bacillus surrounds itself with an endospore, which is a tough, natural outer shell that protects it from light, heat, pressure, acid, lack of oxygen, and other environmental factors. Bacillus changes into its active form in the large intestine to colonize the gut to encourage microbial diversity of commensal gut bacteria. In its active form, Bacillus can increase microbial diversity by changing the pH and increasing the production of short-chain fatty acids. The combination of specific strains, particularly Bacillus coagulans, Bacillus clausii, and Bacillus subtilis, relieve symptoms of common GI complaints and reinforce healthy gut function.


The discovery that the gut barrier plays a key role in immune health fueled the search to strengthen it. Research has shown that the binding capabilities of immunoglobulins have a positive effect on gut barrier function. 

The supplement we recommend: BioFlora

To combine the benefits of bacillus and immunoglobulins, we most often recommend NutriRestore’s Bio Flora

In the search for innovative ways to improve microbiome diversity, we have combined our blend of spore-forming probiotics alongside immunoglobulins uniquely shown to bind to bacteria and toxins, driving immune response. 

IgG (Immunoglobulin G) helps to maintain a healthy intestinal immune system by binding a broad range of microbes and toxins within the gut lumen. As these unwanted triggers are removed, it resets healthy immune tolerance and builds a stronger barrier to the external environment in the gut. Serum-derived bovine immunoglobulins have the highest IgG concentration available for GI and immune challenges where allergens are a significant concern.

This product is a spore-based, broad-spectrum probiotic formula designed to promote a healthy gut microflora, protect mucosal integrity, and relieve small intestinal bacterial overgrowth (SIBO). Each capsule provides key Bacillus spore-forming probiotic strains that remain in a dormant protective state in the harsh gastrointestinal environment yet become active on target to colonize and recondition the gut. Uniquely included in this formula are serum-derived bovine immunoglobulins that bind to microbes and toxins, that are common in SIBO, to help eliminate them from the body.

Bio Flora benefits:

    • Helps maintain normal gastrointestinal balance
    • Provides concentrated immunoglobulins to enhance mucosal immunity
    • Supports digestion and micronutrient absorption
    • Maintains GI barrier health and integrity

Bio Flora does not contain wheat, gluten, soy, corn, dairy products, fish, shellfish, peanuts, tree nuts, eggs, artificial colors, artificial sweeteners or preservatives. If you are pregnant or nursing, consult your physician before taking this product.

How my at-home, online SIBO program can help you

Although SIBO is a common condition, it can be difficult for many SIBO sufferers to solve the problem. It’s also common for many with SIBO to remedy the situation, only to have it come back time and again. 

This is one reason I created the online Gut Health and SIBO program. It’s impossible to reach each one of the 36-million-plus SIBO sufferers in the United States, especially when it comes to in-person appointments. But through my videos and interactive case studies, I’ll educate you on how to overcome common mistakes SIBO sufferers make and help you learn the key considerations for remedying SIBO the right way. 

While every individual has a unique story and mixture of physiological factors contributing to what they are dealing with, this platform can offer education and resources with options for almost every SIBO sufferer. 

Whether this is your first time encountering gut problems, your fifth time having SIBO, or you have other complications like leaky gut that accompany the SIBO, I designed this program to accommodate each of those scenarios. Throughout the lessons, I’ll teach you how to individualize your program and how to choose the right supplements for your individual needs. 

An important aspect that many patients ignore after addressing SIBO is how to avoid getting it again in the future. By following my at-home SIBO program, you will receive step-by-step instructions on how to improve your probability of keeping SIBO at bay.
