SIBO, or Small Intestinal Bacterial Overgrowth, refers to an abnormal increase in the number and/or type of bacteria in the small intestine. Historically recognized in the context of various gastrointestinal disorders, SIBO gained prominence in the late 20th century as research highlighted its role in malabsorption, digestive symptoms, and related health issues. Initially diagnosed through clinical observations, the advent of breath testing technologies in the early 2000s provided a more reliable means to detect this condition by measuring hydrogen and methane produced by bacteria during carbohydrate fermentation. Today, SIBO is acknowledged not only for its impact on digestive health but also for its potential influence on conditions such as irritable bowel syndrome (IBS), chronic fatigue, and metabolic disturbances, driving further research and discussion in the fields of gastroenterology and functional medicine.

Elevated SIBO (Small Intestinal Bacterial Overgrowth) levels suggest an overgrowth of bacteria in the small intestine, which can lead to symptoms such as bloating, gas, diarrhea, and abdominal pain. This can indicate an imbalance in gut microbial ecology or dysfunction in intestinal motility and may be linked to conditions like irritable bowel syndrome (IBS) or other gastrointestinal disorders. Conversely, low SIBO levels may imply a healthier balance of gut bacteria; however, extremely low levels could also indicate inadequate bacterial presence for optimal digestion and nutrient absorption. Understanding the context of these levels, including symptoms and health history, is crucial for interpreting results and determining appropriate interventions.

SIBO, or Small Intestinal Bacterial Overgrowth, is assessed in the Gut Zoomer test, providing critical insights into the microbial diversity of the small intestine. This biomarker helps evaluate the presence of abnormal bacterial populations that can lead to digestive issues and nutrient malabsorption. By identifying SIBO, practitioners can tailor treatment plans that restore balance to gut health, enhance digestion, and improve overall wellbeing.
