The gut microbiome is an important ecosystem of microbes that lives in each one of us, and its strength affects our overall health.However, the small intestine is an underappreciated part of the gut microbiome. Most of the research into our microbiomes has focused on the other end of the gastrointestinal tract, namely, the colon. And poop samples are an easy way to analyze the microbiome in that lower part of the gut.Better understanding microbiome disruptions in the small intestines may allow researchers to better understand disorders like irritable bowel syndrome, and celiac disease. Dr. Christopher Damman, associate professor of gastroenterology at the University of Washington, gives SciFri producer Kathleen Davis a crash course in the microbiome of the small intestine.Transcripts for each segment will be available after the show airs on sciencefriday.com.
