Gut sequencing and interventions are effective only in obvious cases like severe yeast or bacterial overgrowth, often linked to diet and antibiotics.

“So, all right, a patient that came to me two years ago who had a history of sinusitis, horrible history of sinusitis. So she probably had to do an Augmentin course six times a year because of recurrent sinusitis. She had three surgical procedures, just couldn't get better. So I started working with her. It became pretty clear to me that there was something in her diet that was creating an inflammatory environment that wasn't a structural problem. So we made a lot of dietary changes, things got better, but in parallel to that I sort of suspected that 10 years of 6 cycles of Augmentin probably altered her gut. And so, yeah, she's an example of someone where I would do a sequence and can be like, "Lo and behold, you're all yeast." Right? Not surprisingly, and disproportionate bacterial overgrowth.”
