Small Intestinal Bacterial Overgrowth (SIBO)

Small Intestinal Bacterial Overgrowth (SIBO) occurs when an abnormal number or type of bacteria grow in the small intestine, where fewer bacteria normally reside compared to the colon. This excess bacterial growth can interfere with digestion and nutrient absorption, leading to symptoms like bloating, gas, diarrhea, or abdominal pain. Factors such as slowed gut motility or structural abnormalities can contribute. SIBO is diagnosed through breath tests detecting gases produced by bacteria. Treatment typically involves antibiotics, dietary changes, and addressing underlying causes to restore balance in the small intestine's microbial population.
