What is Small Intestine Bacterial Overgrowth (SIBO)?

If you have been diagnosed with Irritable Bowel Syndrome (IBS), chances are that you actually have small intestine bacterial overgrowth (SIBO). Normally, you have small amounts of bacteria present in your small intestine. In SIBO, the bacteria proliferate in your small intestine where they ferment sugars from your food leading to digestive symptoms.
