As with any ailment, symptoms are different for everyone. For me, SIBO was a mix of everything. Now that SIBO is gone, I’m able to see the symptoms more clearly because I no longer have them.
My SIBO Symptoms
Gut
- Stomach distention (looking “pregnant”)
- Tautness of the stomach (hard, not squishy to the touch)
- Gas & bloating
- Irregular BMs
- Watery BMs
- “Twitching” of muscles in my GI
- Nausea
- Cravings for high FODMAP foods
- Coated tongue
Skin
- Cheek rosacea
- Dyshidrotic eczema on toes & fingers
- Random itchy patches of skin that resolved
- Mild acne
- Redness around my eyes
- Dark under-eye circles
- Severe histamine reactions to bug bites
Head & Brain
- Hypersensitivity to barometric pressure & changes
- Head pressure
- Headaches
- Brain fog
Other
- Severe sinus symptoms
What I Did Next
If this list sounds familiar, here’s what helped me get answers:
- Got a SIBO breath test (compare breath test prices)
- Tested at home with the FoodMarble AIRE (read my review)
- Read my full SIBO story: UH-OH, SIBO.
