Small Intestinal Bacterial Overgrowth (SIBO)

Small Intestinal Bacterial Overgrowth (SIBO) is a condition where both aerobic and anaerobic bacteria overgrow in the small intestine. Typically, the small intestine contains low levels of bacteria, unlike the large intestine which harbors a diverse and large ecosystem of microbes. Our gut microbes play a large role in health and disease. Important positive functions of microbes include degrading carbohydrates for fuel, creating vitamins for good health and maintaining normal function of our immune system.

An elemental diet is a nutritionally complete, easily digestible liquid formula made up of pre-digested nutrients—free amino acids, simple carbohydrates, and essential fats. It allows the gut to rest while reducing bacterial fermentation, helping to starve harmful microbes linked to gut dysbiosis, SIBO, IBS, and chronic inflammation (IBD). As a GI-focused Registered Dietitian, I provide assessment, guidance, and monitoring to safely implement an elemental diet protocol, ensuring it is personalized, nutritionally adequate, and integrated into a broader gut-restoration plan to support healing, microbial balance, and long-term digestive health.
