Small Intestinal Bacterial Overgrowth (SIBO)
SIBO (Small Intestinal Bacterial Overgrowth) is characterized by Frequent bloating, gas, stomach discomfort, or inconsistent digestion. The symptoms often come and go without a clear explanation. For many people, this concern often goes overlooked or misdiagnosed for years.
Our naturopathic clinic in Oakville offers a comprehensive and natural approach to SIBO. This approach includes testing guidance, individualized diet support, herbal therapies, and long-term gut-healing strategies designed to restore balance and support your overall well-being.
What Is SIBO?
SIBO (Small Intestinal Bacterial Overgrowth) occurs when bacteria that normally live in the large small intestine start to accumulate in the small intestine. Even beneficial bacteria can create problems when they grow in the wrong location and out of proportion. This imbalance interferes with digestion, nutrient absorption, and motility. It can often result in chronic digestive symptoms.
SIBO may present differently depending on the type:
- Hydrogen-dominant SIBO (often linked with diarrhea)
- Methane-dominant SIBO/IMO (often linked with constipation)
- Mixed gas SIBO (constipation or diarrhea)
Key points:
- SIBO can impact how well your body digests food and absorbs nutrients
- Different SIBO types require different naturopathic treatment strategies
- Identifying root causes helps prevent recurring symptoms

SIBO Symptoms
While symptoms vary from person to person, many individuals experience a mix of digestive and non-digestive concerns. Common symptoms include:
- Bloating after meals
- Abdominal discomfort or cramping
- Excessive gas or belching
- Constipation
- Diarrhea or alternating bowel habits
- Fatigue and low energy
- Brain fog or difficulty concentrating
- Nausea
- Heartburn
- Food intolerances or sensitivities
- Unexpected weight changes
These symptoms can significantly impact daily comfort, work performance, social life, and overall confidence in eating. A proper assessment can help determine whether SIBO is playing a role.
What Causes SIBO?
SIBO is rarely caused by one factor alone. Instead, it often results from a combination of digestive, structural, and lifestyle factors that create an environment where bacteria can easily overgrow.
Functional Causes
These issues directly affect digestion and gut movement:
- Low stomach acid
- Slow gut motility
- Pancreatic enzyme insufficiency
- Reduced bile flow
- Structural abnormalities in the small intestine
- Poorly coordinated digestive processes
When food moves too slowly through the small intestine or when digestive secretions are impaired, bacteria can accumulate and multiply.
Lifestyle & Medical Causes
These external or health-related factors often contribute to SIBO development:
- Chronic stress and anxiety
- Long-term use of certain medications
- IBS (Irritable Bowel Syndrome)
- Hypothyroidism
- Diabetes
- Past abdominal surgeries
- Previous food poisoning or traveler’s diarrhea
- Autoimmune conditions
Identifying underlying contributors is essential for long-term success, since treating symptoms alone often isn’t enough to prevent recurrence.
SIBO Testing in Canada
A SIBO breath test is the most widely used tool for diagnosing SIBO. The test measures hydrogen and methane gas levels in your breath after drinking a lactulose or glucose solution. These gases are produced by bacteria in the small intestine and absorbed into the bloodstream before being exhaled.

We provide support with:
- Choosing between a lactulose and a glucose breath test
- Accessing a SIBO Test Kit in Canada
- Understanding your test results
- Creating a treatment plan based on your SIBO type
Accurate testing helps determine the most effective path forward, especially when differentiating between hydrogen, methane (IMO), and hydrogen sulfide SIBO.
