65: Rethinking SIBO: Why Antibiotics Fail, The Hidden Fungal Factor + Testing That Actually Works | Angela Pifer

Hey Functional Friends!This week I'm sitting down with Angela Pifer — SIBO expert and creator of the massive Cracking the SIBO Code Summit — for what might be the most comprehensive, paradigm-shifting conversation about SIBO you'll ever hear. Angela drops absolute bombs on the conventional treatment approach: why the standard "kill phase first" algorithm is causing recurrence, how 2/3 of SIBO cases also have fungal overgrowth that gets completely ignored, and why we need to flip the entire approach on its head. We dive deep into the vagus nerve connection, the shocking lack of validation behind popular tests (yes, we're calling out TRIO Smart and GI Map), and why antibiotics should be your last resort, not your first line. If you're a practitioner treating gut issues or dealing with recurrent SIBO yourself, this conversation will fundamentally change your approach.Angela Pifer is a Functional Medicine Nutritionist with over 20 years of clinical experience.
