Small intestinal bacterial overgrowth is a condition in which excessive bacteria accumulate in the small intestine, where bacterial levels are normally low. This overgrowth can disrupt digestion, impair nutrient absorption, and lead to persistent gastrointestinal symptoms. In an integrative medicine model, SIBO is viewed not simply as bacterial overgrowth, but as a reflection of underlying dysfunction in gut motility, digestive capacity, and microbiome balance.
Rather than focusing solely on bacterial eradication, an integrative approach combines conventional medical care with evidence-based complementary therapies to identify and address root contributors. These may include impaired gut motility, low stomach acid, enzyme deficiencies, prior infections, chronic stress, and structural or functional digestive issues.
Symptoms can vary depending on the type of gas produced (hydrogen, methane, or hydrogen sulfide) and may fluctuate over time.
