Why SIBO Keeps Coming Back | Root Causes Beyond the Gut (Mold, Nervous System & More)
Let’s get real—if you’ve treated SIBO and it keeps coming back, it’s not because you didn’t try hard enough - It’s because SIBO isn’t actually the root problem. It’s a symptom. A red flag. A sign that your gut is out of balance for a deeper reason.
Here’s what I wish more people knew:
You can kill off the bacteria over and over, but if the why behind your SIBO isn’t addressed, it’s like bailing water from a sinking boat without patching the hole.
So what causes that hole?
Sometimes it's mold exposure wrecking your detox and immune system.
Sometimes it’s parasites or heavy metals suppressing gut function.
And a lot of the time, it's your nervous system being stuck in survival mode—because when you're chronically in fight-or-flight, your digestion slows, motility gets sluggish, and the whole system backs up.
SIBO can also stem from:
Low stomach acid
Poor bile flow (especially if your gallbladder’s been removed)
Sluggish thyroid
Abdominal adhesions from surgery or endometriosis
Or even long-term use of acid blockers or antibiotics
The truth is: You can’t supplement or low-FODMAP your way out of SIBO for good if you don’t address the terrain that allowed it in the first place.
If you’re tired of the constant bloating, cycling through protocols, restrictive diets, and expensive supplements just to end up back where you started... this is your sign to go deeper.
