🦠 Bloating? Gas? Food Sensitivities? Brain Fog? It Might Be SIBO.
SIBO (Small Intestinal Bacterial Overgrowth) occurs when bacteria that normally belong in the large intestine begin growing in the small intestine, where they don’t belong. This can interfere with digestion, nutrient absorption, and overall gut health.
🚩 Common Symptoms:
• Bloating (especially after meals)
• Excessive gas or belching
• Abdominal pain or discomfort
• Diarrhea, constipation, or alternating between both
• Food sensitivities
• Brain fog
• Fatigue
• Unexplained vitamin deficiencies (especially B12 and iron)
• Weight loss or difficulty maintaining weight
⚠️ Risk Factors:
• IBS
• Chronic acid reflux medication use
• Diabetes
• Prior abdominal surgery
• Autoimmune disorders
• Motility disorders
• Chronic stress
🔬 How is SIBO Tested?
The most common test is a non-invasive breath test that measures hydrogen and methane gases produced by bacteria after drinking a special sugar solution. Functional medicine evaluation may also include stool testing, nutrient assessment, and investigation of underlying root causes.
💊 How is SIBO Treated?
Treatment depends on the type of SIBO and the underlying cause but may include:
• Prescription antibiotics such as rifaximin
• Herbal antimicrobial protocols
• Dietary modifications (often low-FODMAP or targeted elimination diets)
• Prokinetic therapies to improve gut motility
• Nutritional support and correction of deficiencies
• Addressing root causes such as thyroid dysfunction, diabetes, mold exposure, or chronic inflammation
The key to successful treatment isn’t just eliminating the bacterial overgrowth—it’s understanding why it developed in the first place.
If you’ve been told you have IBS but continue to struggle with bloating, digestive issues, or unexplained symptoms, it may be worth exploring whether SIBO is contributing to your symptoms.
