SIBO (small intestinal bacterial overgrowth) occurs when bacteria that should live in the large intestine migrate into and colonize the small intestine, where they don't belong. The result is fermentation of carbohydrates in the wrong location, producing gas, bloating, pain, and a cascade of downstream effects on nutrient absorption, gut permeability, and systemic inflammation.
Candida overgrowth and broader gut dysbiosis follow similar patterns: disrupted microbial balance leads to a domino effect of symptoms that often seem unrelated — brain fog, fatigue, skin issues, hormonal disruption, food sensitivities, and mood changes. These are all downstream of a gut that is not functioning as it should.
This is one of the most important and underappreciated areas of functional medicine. Identifying and addressing these patterns often resolves complaints that patients have been living with for years without explanation.
