SIBO, Bloating & IBS Treatment: Work With a Naturopathic Doctor Who Looks at the Root Cause
Many patients I see are struggling with bloating, IBS, or suspected SIBO—and feel stuck despite trying diets, supplements, or previous treatments. While SIBO can play a role, it’s often not the root cause. A naturopathic approach focuses on identifying what’s driving your symptoms—such as motility issues, gut-brain dysfunction, or microbiome imbalances—and building a personalized plan for long-term gut health support, not just temporary relief. I work with patients in Burlington, Ontario and virtually across Ontario who are dealing with SIBO, bloating, and IBS.
Looking for a Naturopathic Doctor for SIBO?
As a naturopathic doctor, I often see patients who:
Have been diagnosed with SIBO but didn’t improve with treatment
Suspect SIBO based on symptoms like bloating and food reactions
Feel confused by conflicting information online
If that’s you, you’re not alone—and more importantly:
👉 SIBO is rarely the whole story.
What Is SIBO?
SIBO (small intestinal bacterial overgrowth) refers to an increase in bacteria in the small intestine, where bacterial levels are normally low. This can interfere with digestion and lead to symptoms like:
Gas
Bloating
Changes in bowel habits
However, as a naturopathic doctor, I always emphasize that SIBO is not a single, uniform condition, and it does not explain every case of bloating.
What Are the Symptoms of SIBO?
Bloating (often after eating)
Excess gas
Abdominal discomfort
Diarrhea, constipation, or both
Food sensitivities
It’s also important to know that as a naturopathic doctor, I often see these symptoms in many different conditions—not just SIBO. This includes irritable bowel syndrome (IBS) and disorders of gut-brain interaction, or DGBIs.
Why Am I Bloated? Is It Really SIBO?
This is one of the most common questions I get. Bloating is not specific to SIBO. These symptoms can also be caused by:
IBS (irritable bowel syndrome)
Gut-brain interaction disorders
Food intolerances, such as lactose intolerance
Motility issues
Hormonal changes
This overlap is why many people are misdiagnosed or overtreated for SIBO.
The Problem With How SIBO Is Treated Online
SIBO is often presented online as:
The main cause of bloating
Easy to diagnose with a breath test
Straightforward to treat
In reality, I often see that SIBO symptoms overlap with many conditions, and testing has limitations. This doesn’t mean SIBO isn’t real—it means it needs a more nuanced, clinical approach.
How Does SIBO Actually Develop?
SIBO is usually secondary to other issues, not the root cause. As a naturopathic doctor, I look for known risk factors like the following:
Impaired motility (slow movement of the small intestine)
Gut-brain signalling dysfunction
Post-infectious changes (after food poisoning)
Structural digestive changes
History of bowel surgery
Long-term use of acid-suppressing medications (PPIs)
👉 This is why treating SIBO alone often leads to recurrence 👈
SIBO Testing: Is It Accurate?
Lactulose or glucose breath testing are commonly used, but they are not perfect tests. SIBO breath tests measure hydrogen and methane gas production (not bacteria directly) from hydrogen- and methane-producing bacteria. However, there are several limitations:
Influenced by gut transit time
False positives and false negatives are common
Requires proper preparation
As a naturopathic doctor, I use testing selectively and contextually—not as a standalone diagnosis.
SIBO vs IBS: What’s the Difference?
This is a major point of confusion. You may see online that SIBO causes up to 80 percent of IBS — this is simply is not true. IBS is a disorder of gut-brain interaction (DGBI) and involves several mechanisms including impaired motility, a microbiome shift, alterened mucosal and immune activation, and several other mechanisms. SIBO, on the other hand, is defined as an abnormal proliferation of bacteria in the small intestine, typically colonic-type bacteria not normally present in this region in significant quantities.
👉 As a naturopathic doctor, I often see overlap—but they are not the same condition.
What Is the Best Natural Treatment for SIBO?
This is where most online advice falls short. There are many antimicrobial supplements (both herbal and prescription) that can help reduce hydrogen- and methane-producing bacteria in the small intestine. In some cases, these can improve symptoms—especially in the short term.
But here’s what I see all the time in practice: People complete a SIBO protocol — and their symptoms come back.
That’s because SIBO treatment isn’t just about reducing bacteria; it’s about understanding why the overgrowth happened in the first place.
A More Holistic SIBO Treatment Approach
As a naturopathic doctor, I build treatment plans that may include:
Motility support — improving movement through the digestive tract
Gut-brain support — addressing nervous system regulation
Nutrition strategies — focusing on individualized nutrition recommendations that are not overly restrictive
Targeted supplementation — based on your physiology
Antimicrobial therapy (when appropriate) — these can be herbal or pharmaceutical therapies
👉 The goal is long-term gut health support—not temporary symptom relief.
When Should You Actually Test for SIBO?
As a naturopathic doctor, I consider SIBO testing when:
Symptoms are persistent and unexplained
There’s a history of infection or food poisoning
Bloating is severe and meal-related
👉 But testing too early—or focusing only on SIBO—can delay proper care.
Frequently Asked Questions About SIBO
Can a naturopathic doctor treat SIBO?
Yes. As a naturopathic doctor, I use a combination of testing, nutrition, gut-brain therapies, and targeted treatments to support SIBO and overall digestive health.
What is the fastest way to eradicate SIBO naturally?
There is no one-size-fits-all “quick fix.” A natural approach focuses on underlying causes, not just short-term symptom relief. For patients wishing to take the pharmaceutical equivalent (Rifaxamin), we focus on the next steps after this therapy to help avoid SIBO from re-occuring.
Do I need a breath test for SIBO?
Not always. Testing can be helpful, but it should be interpreted in the context of your full clinical picture.
Why didn’t my SIBO treatment work?
In many cases, treatment fails because root causes like motility or gut-brain dysfunction weren’t addressed.
Ready for a Clear, Structured Approach to SIBO?
From a clinical perspective, there are a few key things to understand:
✅ SIBO is not always the root cause. It should be viewed as a “lagging indicator” — there’s something else happening that is causing it.
✅ Symptoms like bloating are multi-factorial
✅ Testing has limitations
✅ Treatment requires a holistic, personalized approach
✅ Long-term success comes from addressing function—not just bacteria
As a naturopathic doctor, I work with patients who:
Feel stuck despite previous SIBO treatment
Want a natural, evidence-informed approach
Are looking for long-term gut health support
