Summary

One theory of small intestinal bacterial overgrowth (SIBO) is that it’s caused by bacteria in the colon moving up. A new study on one section of the small intestine, the jejunum, challenges that concept. The study—which used a new technique called polymerized chain reaction (PCR) to look at bacterial genomes—found that the jejunum has its own unique microbiota. Positive breath tests also did not correlate with bacterial overgrowth in the jejunum, but rather jejunal dysfunction. Dr. Richard McCallum, gastroenterologist and researcher on the study, explains more about these findings and what they might mean for SIBO treatment. We also discuss how proton pump inhibitors (PPIs), breath tests, diet, prokinetics, and hypochlorhydria fit into this picture. Join us for a very insightful conversation! https://drruscio.com/?p=32517

0:42.8	This is Dr. Rucho.
0:43.8	Today I'm here with Dr. Richard McCallum.
0:45.9	And we are going to be talking about a presentation I heard some great things about from the recent Sibocon conference entitled the microbiota and the jujunum
0:56.2	relationship to bacterial overgrowth and breath tests. So Richard, thank you for coming on the show
1:02.6	today. Glad to be on the show. Thank you for inviting me. Absolutely. Can you tell people just
1:08.9	briefly about your background before we jump in on everything else?
1:13.6	Yes. I'm a gastroenterologist. I grew up in Brisbane, Australia. Well, let's make it Brisbane, Australia in the name of the mates from down under.
1:24.8	And came over with the thought I might evolve my knowledge base and go back
1:31.4	and re-contribute to the Australian developments, but I got lured away into academic medicine
1:38.5	over here and have evolved up the latter into directing divisions of gastroenterology, training programs,
1:47.7	fellowships, departments of medicine. I've been a dean. I've run the gamut, and now I'm happily
1:54.3	back into gastrology research, if you like, NIH-funded research, trying to continue to work.
2:03.8	I'm a motility specialist, if you look up my sort of title in some ways.
