What's inside

What you'll understand after reading.

A clinical orientation — not a sales pitch, not a wellness primer. Eighteen pages, twenty-six citations, one job: get you to the right next step.
  1. i.

    What H. pylori is — and why most carriers don't know they have it.

    The basic biology, the prevalence (roughly 1 in 3 American adults), the reasons it stays clinically silent for years, and the implications of that silence for the conditions it has been associated with.

  2. ii.

    Why standard workups miss the systemic connections.

    A short history of the diagnostic gap — how the workup order sets settled around 'GI symptoms only', and what thirty years of peer-reviewed literature has done to that boundary since.

  3. iii.

    The four mechanisms in plain language.

    Hypochlorhydria · hepcidin / inflammation · nutrient malabsorption · molecular mimicry. One paragraph per mechanism, with the strength of the underlying evidence tagged transparently.

  4. iv.

    Which eight conditions have peer-reviewed associations.

    One paragraph per condition — iron, fatigue, brain fog, thyroid, hives, metabolic, B12, rosacea — with the strongest published finding and the evidence tier inline.

  5. v.

    What the three evidence tiers mean.

    Strong, Moderate, Exploratory — what each threshold requires, why every claim across the series is tagged, and why exploratory findings are flagged on the cover instead of buried.

  6. vi.

    What to do next — if you recognise your condition.

    A short decision tree — by primary symptom, by lab pattern, by clinical context — that routes you to the condition-specific investigation guide, the testing kit, or back to your primary care physician.

§ 03 · A starting point, not a destination
Recognise your condition?

If you recognise your condition in the overview, there is a full investigation guide for it.

Each condition has its own thirty-to-forty page guide — mechanism, the standard workup's blind spot, the secondary labs to request, and the conversation script for your next appointment. The Overview tells you whether one applies. The guides go deep.
