SIBO (Small Intestinal Bacterial Overgrowth) is a condition where excessive bacteria in the small intestine cause symptoms like bloating, pain, and diarrhea. Diet plays a key role in managing these symptoms by avoiding high-FODMAP foods that feed bacteria and promoting nutrient absorption. A structured SIBO diet helps reduce discomfort and improve quality of life.
1.1. What is SIBO?
SIBO (Small Intestinal Bacterial Overgrowth) is a condition where an excessive amount of bacteria grows in the small intestine. This bacterial overgrowth disrupts normal digestion and nutrient absorption, leading to symptoms like bloating, abdominal pain, diarrhea, and fatigue. The small intestine, responsible for most of our nutrient absorption, becomes overwhelmed when bacteria ferment undigested carbohydrates, producing gas and causing discomfort. SIBO can result from slowed intestinal motility, anatomical abnormalities, or conditions that impair the body’s natural clearance of bacteria. It is often linked to malabsorption of nutrients and can significantly impact quality of life if left untreated. Understanding SIBO is crucial for developing an effective dietary and treatment plan to manage symptoms and restore gut health.
