Naturopathic doctors commonly treat dysbiosis and one form of dysbiosis that has received increasing attention is Small Intestinal Bacterial Overgrowth (SIBO). This condition occurs when excessive bacteria, often originating from the colon or mouth, accumulate in the small intestine.(1) Unlike the colon, which normally houses billions of bacteria that aid in fiber breakdown, the small intestine is designed to host relatively few microorganisms. Protective mechanisms such as stomach acid and normal intestinal motility help maintain this balance. When these defenses are compromised, SIBO can develop.
Why is the Small Intestine Vulnerable to Bacterial Overgrowth?
Naturopathic medicine always seeks to understand the cause of illness and the causes of SIBO are complex and multifactorial. Impaired intestinal motility is a leading factor, often seen in individuals with irritable bowel syndrome (IBS), diabetes, or post-surgical adhesions that slow food transit. Long-term use of proton pump inhibitors (PPIs), medications prescribed for acid reflux, can also reduce stomach acid, creating an environment that favors bacterial overgrowth.(2) Additional contributors include structural abnormalities of the GI tract, immune deficiencies and systemic illnesses such as hypothyroidism, celiac disease and chronic pancreatitis.
SIBO is more common than once believed. Research suggests it may affect up to one in seven people and is present in up to 80–90% of those with IBS.(3) Women and older adults are particularly at risk and prevalence appears to increase with age. Naturopathic doctors use improved diagnostic tools, especially breath testing, to make recognition more widespread.
Root Causes of SIBO in Naturopathic Medicine
The symptoms of SIBO are often non-specific and overlap with other digestive conditions, which makes diagnosis challenging. Common complaints include bloating, abdominal pain, distension, excessive gas, diarrhea and cramping. Some patients experience constipation when methane-producing archaea dominate, while others may alternate between loose stools and sluggish bowels.
Malabsorption and Nutrient Deficiencies in SIBO
Malabsorption is another important feature in this condition. Overgrowth of bacteria can interfere with the breakdown and absorption of carbohydrates, proteins and fats. Carbohydrate malabsorption often leads to gas production and bloating. Low stomach acid reduces protein digestion, while fat malabsorption may cause deficiencies in fat-soluble vitamins A, D, E and K. Vitamin B-12 deficiency is also common, contributing to fatigue, weakness and neurological symptoms such as tingling or numbness.
In some cases, patients experience unintended weight loss due to malnutrition and a sense of fullness from bloating. Because these symptoms mimic conditions such as celiac disease, inflammatory bowel disease (IBD), or even gastrointestinal cancers, proper testing is essential.

How Naturopathic Doctors Diagnose SIBO?
SIBO Diagnosis begins with ruling out more serious conditions. Once it is suspected by a naturopathic doctor, several methods can be used. Small intestine aspirate and culture, obtained through endoscopy, is considered the gold standard. However, it is invasive, costly and uncomfortable, so it is rarely the first choice.
Breath testing is the most common diagnostic tool and this test can be ordered by Naturopathic Doctors.(4) Patients consume a sugar substrate such as lactulose or glucose and levels of hydrogen or methane are measured in the breath. Early rises in these gases suggest SIBO. Blood tests can assess nutrient deficiencies or inflammatory markers, while stool tests may reveal fat malabsorption. Motility studies can help determine whether slowed intestinal function contributes to overgrowth.
Though not life-threatening, SIBO can significantly impair quality of life. Accurate diagnosis is critical because naturopathic treatment must be tailored to the underlying cause. A naturopathic doctor can help guide patients through the diagnostic process, ensuring that testing is comprehensive and individualized.

Lifestyle Health | Yoga, meditation, mindful eating. Adequate sleep & hydration. Regular movement to support gut motility. |
Naturopathic Approaches to SIBO Treatment
The main objective of SIBO treatment is to reduce bacterial overgrowth, restore normal intestinal function and address nutrient deficiencies. Conventional therapies often include antibiotics, but recurrence is common, highlighting the need for broader approaches. This is where naturopathic medicine provides valuable strategies.
Naturopathy emphasizes working with the body’s healing systems and SIBO management is no exception. Herbal antimicrobials such as oregano oil, berberine and garlic extract have shown promise in reducing bacterial overgrowth. These treatments aim not to sterilize the small intestine but to restore microbial balance.
Dietary modifications are central to symptom management. The low-FODMAP diet, which reduces fermentable carbohydrates, can alleviate bloating and gas.(5) However, it is not a cure and should be used temporarily under the guidance of a naturopathic doctor. The elemental diet, consisting of nutrients in their simplest form, has also been used to “starve” bacteria while providing nourishment to the patient.
Probiotic therapy remains controversial in SIBO management. Some studies show reduced hydrogen levels on breath tests, while others report worsened bloating and brain fog. The effectiveness of probiotics depends on the strain and the individual’s unique microbiome. A naturopath can determine whether probiotics are appropriate, tailoring recommendations to each patient.

Lifestyle interventions are equally important in naturopathic medicine. Stress management, adequate sleep and daily physical activity all support gut motility and immune balance. Since stress and irregular routines can impair digestive function, practices such as yoga, meditation and mindful eating may improve outcomes. Correcting nutritional deficiencies is also vital. Supplementation with B-12, fat-soluble vitamins and minerals such as magnesium and zinc can help restore energy and tissue repair. Patients should also remain well-hydrated and maintain a diet rich in whole foods once acute symptoms subside.
SIBO highlights the intricate relationship between the microbiome, digestion and systemic health. While its symptoms can be frustrating and sometimes debilitating, understanding its root causes allows for targeted treatment. A comprehensive approach that combines accurate diagnosis, dietary changes, herbal therapies and supportive lifestyle practices offers the best chance of long-term relief.
