Gut
Designed for a 60-second scan in primary care. Use this to explain why this theory fits, what would weaken it, and which tests are most worth discussing.
Why this still fits
I want to evaluate whether digestive triggers are contributing to my brain fog and how to separate broad gut involvement from SIBO, food sensitivity, reflux, anxiety, or medication effects.
What would weaken it
- -No digestive symptoms, no meal-linked worsening, and no sign that the gut and brain move together.
- -The fog is clearly driven by sleep, posture, mood, medication changes, or another non-gut trigger.
- -A narrower cause such as SIBO, celiac, histamine, or sugar instability fits the pattern more precisely.
Key points to communicate
- •I want to know whether this is broad gut involvement or a more specific gut diagnosis hiding inside it.
- •Please separate gut-driven fog from SIBO, celiac, food sensitivity, histamine, and reflux patterns.
- •If the gut is the right lane, I want to know what first-line tests or tracking would clarify it fastest.
Bring this to the visit
- •A GI symptom log: bloating, gas, stool changes, and timing relative to meals.
- •Any prior GI testing: stool analysis, breath tests, endoscopy, celiac panel.
- •Current diet description: fiber intake, fermented foods, processed food frequency.
- •Medication list especially antibiotics, PPIs, NSAIDs, and probiotics.
Useful screening structure
- -Celiac panel (tTG-IgA, total IgA) as a mandatory first-line screen.
- -Hydrogen/methane breath test for SIBO if post-prandial symptoms are prominent.
- -Comprehensive stool analysis if chronic symptoms suggest dysbiosis or inflammation.
Tests and measurements to discuss
SIBO Breath Test
What this helps clarify: Screens for small intestinal bacterial overgrowth
Range context
Negative for H₂/CH₄ rise
How to use the result
Save the result with date and symptoms from the same week.
tTG-IgA (Celiac)
What this helps clarify: Patient-facing celiac serology explainer route focused on the test wording users actually bring from clinician visits.
Range context
Serology context
How to use the result
Save the result with date and symptoms from the same week.
Medication Review
What this helps clarify: Medication-related brain fog is often missed because nobody lays the full timeline out in one place.
Range context
Structured medication timeline + risk review
How to use the result
Ask whether a pharmacist-led medication therapy management review is available.
A1c + fasting glucose context review (metabolic cross-check)
If post-meal fog includes shaky/sweaty episodes, glucose instability may overlap with gut triggers. This is a cross-reference test, not a primary gut investigation.
What this helps clarify: This route is for the situation where HbA1c and fasting glucose do not fully explain a strong post-meal or fasting crash pattern.
Range context
Interpret with timing pattern
How to use the result
If the averages are normal but the crashes are repeatable, ask what test would better capture variability.
Questions to ask directly
- •Is my gut likely causing the fog (gut-brain axis), or is the gut a symptom of the same root cause?
- •Should we test for SIBO, celiac, or parasites before assuming general dysbiosis?
- •Are my current probiotics or fermented foods helping or potentially worsening the situation?
- •What's the minimum workup before trying an elimination diet or antimicrobial protocol?
Functional impact snapshot
- -Track fog onset relative to meals: which meal types trigger the worst fog?
- -Rate cognitive function on fasting mornings vs post-meal periods.
- -Note whether GI symptoms and fog improve together during dietary interventions.
Escalate instead of self-managing if
- •Unintentional weight loss, blood in stool, or iron deficiency anemia needing colonoscopy.
- •Severe abdominal pain with fever suggesting acute infection or inflammatory flare.
- •Progressive malnutrition or multiple food intolerances suggesting underlying GI pathology.
