You were right to keep looking.
You're not imagining it. The workup just hasn't gone far enough yet.
Everything checked out. But you still don't feel like yourself.
- You have elevated TPO antibodies and have never been told what triggered them
- Your fatigue and brain fog persist even when your TSH is "in range"
- You have been managing Hashimoto's or Graves' disease for more than a year
- No one has raised H. pylori as a possible upstream factor
- You have never been tested for H. pylori as part of your thyroid workup
- You want to understand whether an active infection could be sustaining your autoimmunity
- Raised thyroid antibodies with no trigger anyone has ever identified
- A Hashimoto's diagnosis with no family history of thyroid disease
- Antibody levels that keep climbing or won't settle despite treatment
- Thyroid symptoms that flare with illness or stress
- hs-CRP running high alongside the thyroid antibodies
- Fatigue that feels inflammatory rather than purely hormonal
- Antibody levels higher than the length of your diagnosis would suggest
- Thyroid function declining faster than expected
- Stomach or gut symptoms alongside the thyroid picture
- Lingering fatigue even with thyroid numbers in the target range
- Low B12 or ferritin found alongside the thyroid autoimmunity
- Symptoms that don't fully lift on thyroid hormone alone
A workup for the thyroid that won't settle.
This guide is written for the patient whose TSH is in range but who still feels off, or whose thyroid antibodies won't quiet down. It maps four ways an unsuspected H. pylori infection has been linked to thyroid autoimmunity, and gives a clear plan for what to test next.
It is not a treatment protocol. It's the investigation itself, written down — so your next move is far more specific than your last, whether you take it to a doctor or pursue it on your own.
-
i.
The clinical signature of Hashimoto's with symptoms that persistHow the picture differs from simple under-replacement, conversion problems, and the other reasons a treated thyroid still doesn't feel handled.
-
ii.
Four pathways the thyroid workup rarely checksThe immune mix-up, ongoing inflammation, the more aggressive strains, and drained nutrients — with the evidence tier for each.
-
iii.
Why 'TSH in range' doesn't always mean 'thyroid handled'What a single headline number can obscure — and the markers worth reading alongside it.
-
iv.
Labs to request beyond a basic panelA short list of secondary markers — thyroid antibodies, B12, ferritin, zinc — read together, not in isolation.
-
v.
Testing options for H. pyloriStool antigen, urea breath test, biopsy — trade-offs, costs, and what each rules in or out.
-
vi.
What positivity changesThe decisions that follow a positive result — eradication, antibody re-test at 3 and 6 months, and the timeline.
-
vii.
A script for raising itA practical framework for discussing testing, interpretation, and next steps — whether with your physician or as a self-directed investigation.
Sharper thinking. Clearer next steps.
-
Know exactly what to investigate next — and why an infection linked to thyroid autoimmunity has slipped through your workup so far.
-
Tell the difference between 'TSH in range' and 'thyroid handled' — and which markers actually matter when symptoms persist.
-
Walk away with a specific plan to act on — with a doctor or on your own — including how to track your thyroid antibodies before and after any change.
Three tiers. One rubric. No exceptions.
Every claim is tagged Strong, Moderate, or Exploratory — so you can see exactly how solid each one is. These four are the heart of why H. pylori is worth investigating in thyroid autoimmunity.
Thyroid autoimmunity · evidence summary
A few honest questions.
Is this medical advice?
No. This guide is educational — written to help you understand the evidence, evaluate testing options, and identify questions worth exploring with your healthcare team or on your own.
Why isn't my endocrinologist already testing for this?
Endocrinologists focus on hormone disorders, and H. pylori is a gastroenterological infection — so the connection sits in the gap between specialties rather than in either one's standard workflow. It's not a failing on your part. The guide shows you the mechanism, the evidence, and exactly what to ask for — whether you raise it with a doctor or decide to pursue it yourself.
Do I need to buy the testing kit?
No — the guide is sold separately from any test or product. It covers all three testing options — stool antigen, urea breath test, biopsy — what each costs, and how to ask for it. But a test only tells you yes or no; the guide is what tells you which test to request and what to do with the result, which is where most people get stuck.
What if my labs are 'in range'?
The guide spends a section on this exact situation — what 'in range' obscures, what to look at in combination, and the secondary markers that frequently shift the picture without changing the headline numbers.
Refund policy?
14 days, no questions. If the guide isn't useful, the Lemon Squeezy receipt has a one-click refund link.
Who wrote it?
Researched, written, and medically reviewed by a physician on the Welyon team. Every claim is drawn from peer-reviewed literature and graded inline — Strong, Moderate, or Exploratory — so you can weigh the evidence behind each one yourself.
