What is called when there is an imbalance between the types of microorganisms in the GI microbiome?

• A. SIBO
• B. Dysbiosis
• C. SIFO
• D. IBS

Answer: (B)

Dysbiosis is the imbalance in the gut microbiota, where the types and relative abundances of microorganisms—bacteria, fungi, and viruses—are disrupted from a healthy composition. This can mean reduced diversity, loss of beneficial species, and overgrowth of potentially harmful ones, which can affect the gut barrier, immune signaling, and metabolism. SIBO describes an overgrowth of bacteria specifically in the small intestine, SIFO is fungal overgrowth, and IBS is a functional syndrome that may involve microbiome changes but is not defined by an imbalance in microbial types.
