What is the effect of small intestinal overgrowths (SIBO) on the digestive system?

Small intestinal overgrowth (SIBO) occurs when there is an abnormal increase in the number of bacteria in the small intestine. This condition can lead to significant negative effects on the digestive system. One of the primary concerns is that these excessive bacteria can damage intestinal villi, which are finger-like projections lining the small intestine responsible for nutrient absorption. When the integrity of the villi is compromised, it can lead to conditions like malabsorption, resulting in nutrient deficiencies and gastrointestinal symptoms such as bloating, diarrhea, and abdominal pain.

Understanding this effect highlights the importance of maintaining a balanced gut microbiome and the delicate ecosystem of bacteria necessary for proper digestive health.
