Small Intestinal Bacterial Overgrowth (SIBO)
Small Intestinal Bacterial Overgrowth (SIBO) is a condition in which excessive bacteria are present in the small intestine. The small intestine plays a critical role in digestion and nutrient absorption. When too many bacteria are present, they can ferment carbohydrates before they are fully digested, producing gases and contributing to symptoms such as bloating, abdominal discomfort, excessive gas, diarrhea, constipation, or a combination of digestive symptoms. From a functional medicine perspective, SIBO is often viewed as a consequence of underlying imbalances rather than a standalone condition. Factors such as impaired gut motility, chronic stress, infections, medication use, structural issues, or other digestive disorders may contribute to its development. Because many gastrointestinal conditions share similar symptoms, SIBO requires proper evaluation and diagnosis by a qualified healthcare practitioner. Health coaches do not diagnose or treat SIBO, but they may support clients in implementing nutrition and lifestyle recommendations as part of a broader care plan.
What is the difference between SIBO and dysbiosis?
SIBO and dysbiosis both involve changes in the gut microbiome, but they are not the same thing. Dysbiosis is a broad term that refers to an imbalance in the composition or function of the gut microbiome. It can occur anywhere in the gastrointestinal tract and may involve an overgrowth of certain microbes, a loss of beneficial microbes, or reduced microbial diversity. SIBO is more specific. It refers to an excessive amount of bacteria in the small intestine, where bacterial populations are normally much lower than in the large intestine. In other words, SIBO is one type of microbial imbalance, while dysbiosis is a broader term that encompasses many different patterns of imbalance throughout the gut.
How are FMCA students taught to support clients with digestive concerns like SIBO?
FMCA students learn about the interconnected factors that influence digestive health, including nutrition, stress, sleep, movement, and the gut microbiome. They are taught to understand digestive conditions through a systems-based lens while remaining within the scope of health coaching. When working with clients experiencing digestive concerns, health coaches focus on behavior change and implementation. This may include supporting adherence to practitioner-recommended nutrition plans, or helping clients develop sustainable eating habits, managing stress, improving sleep, and navigating the challenges of making lifestyle changes over time.
