Small Intestine vs. Colon Microbiome
- The small intestine's microbiome differs greatly from the colon's, like a rainforest versus a desert.
- Similar functions occur, but with different microbial species.
Microbes in the Small Intestine
- Small intestine microbes, like strep and lactobacilli, tolerate oxygen better than colon microbes.
- These microbes are more tolerant of oxygen than those in the colon.
Small Intestine Microbiome and Disorders
- Small intestine microbiome dysfunction can cause IBS and SIBO.
- An overgrowth of microbes in the small intestine can lead to excessive fiber breakdown.
