Why Your Bloating Keeps Coming Back (Even After Treating SIBO)

Why Your Bloating Keeps Coming Back (Even After Treating SIBO)

In this episode, Dr. Emily Kiberd dives deep into SIFO—Small Intestinal Fungal Overgrowth, a commonly missed root cause of gut issues in women with Hashimoto’s.

She explains how fungal overgrowth often develops after treating bacterial overgrowth, when antibiotics or SIBO protocols clear bacteria but leave yeast free to multiply. Dr. Emily explores why women with Hashimoto’s are particularly prone to SIFO: low thyroid slows gut motility, low stomach acid fails to sterilize food, and low bile output removes a natural antifungal defense.

You’ll learn the difference between SIBO and SIFO, how to detect fungal overgrowth on a GI-MAP or OAT, and how to work through the three-phase protocol:
 1️⃣ Starve the yeast by cutting its food source (sugar, alcohol, refined carbs).
 2️⃣ Kill with strategic antifungals—natural or prescription.
 3️⃣ Rebuild the gut with stomach acid, bile support, probiotics, and nervous system regulation.

Dr. Emily also shares practical tools to rewire your gut-brain connection through breathwork, humming, cold exposure, and post-meal walking. Because healing SIFO isn’t just about killing yeast—it’s about creating an internal environment where yeast can’t thrive again.
