What is called when there is an increased numbers of bacteria in the small intestine due to excessive proliferation of 'normal' microbiome under abnormal conditions?

• A. SIBO (small intestinal bacterial overgrowth)
• B. Dysbiosis
• C. SIFO
• D. IBS

Answer: (A)

This situation reflects an abnormal rise in the number of bacteria within the small intestine caused by proliferation of the usual gut microbiota under unfavorable conditions. The term for this is small intestinal bacterial overgrowth, or SIBO. Normally the small intestine harbors relatively few bacteria compared with the colon, so when motility slows, the anatomy alters, or gastric acid is reduced, those normal residents can multiply excessively in the small bowel. That overgrowth disrupts digestion and absorption, leading to symptoms like bloating, gas, abdominal pain, and sometimes fat or vitamin malabsorption. Dysbiosis is a broader imbalance of the gut microbiota that isn’t necessarily about a quantitative overgrowth in the small intestine. SIFO refers to fungal overgrowth, not bacteria. IBS is a functional bowel disorder without a primary overgrowth of bacteria in the small intestine. So the best fit for this description is SIBO.
