Herxheimer Die-Off Reaction: Why Gut Healing Makes IBS Worse First | Ep 84
Send us Fan Mail In this episode, you'll learn: How to tell the difference between a normal "die-off" reaction and a sign that something in your protocol is actually wrong Why feeling worse before feeling better is common — but shouldn't last longer than 14 days How to build a support toolkit so you don't quit right before you'd start seeing results If you've started an elimination diet, a new supplement, or a gut healing protocol and suddenly feel worse instead of better, you're not imagining it — and you're not necessarily doing something wrong. In this episode, Courtney breaks down the Herxheimer response (commonly called "die-off"): what's actually happening in your microbiome when you change your diet or introduce antimicrobial herbs, and why it can look like a full-blown flare, brain fog, fatigue, or even flu-like symptoms. Courtney shares her own experience going through an extended die-off period during one of her personal elimination diets, and explains the general 3-to-14-day timeline most people can expect to move through before symptoms start improving. She also walks through the questions she asks clients when symptoms aren't improving past that window — including a real client case where persistent IBS symptoms turned out to be caused by a prescription medication, not diet or infection at all. This episode also covers when die-off symptoms might be pointing to something deeper, like toxic mold exposure, tick-borne illness, or heavy metal burden, and why nervous system dysregulation and unmanaged stress can stall out even a well-designed gut protocol. Courtney closes with practical guidance for building your own "die-off toolkit" — including how to time a gut protocol around your life and how to build an emotional support plan before symptoms hit, so you're prepared instead of blindsided.
