H. pylori is typically investigated for one condition.
The literature documents eight.
An estimated 1 in 3 Americans may carry H. pylori. Most are never investigated beyond digestive complaints.
A common bacterium. An uncommonly narrow workup.
The standard workup screens H. pylori only when the symptom is digestive. The peer-reviewed literature documents associations across eight conditions — most of which are never tested for it.
Most are asymptomatic and never tested — the carrier rate is the rule, not the exception.

Why your iron won't budge
Refractory iron deficiency in adults who absorb fine on paper — what the standard workup overlooks.
The fatigue nobody can name
Unexplained, post-exertional, "all-labs-normal" fatigue — and the gastric pathway worth ruling out.
The brain fog investigation
Cognitive symptoms with no structural finding — vitamin pathways, inflammation, and the gut–brain axis.
The thyroid–stomach connection
Hashimoto's autoimmunity and the molecular-mimicry hypothesis — the evidence base, plainly graded.
When the hives won't stop
Chronic spontaneous urticaria and the mast cell axis — what an allergist might not order.
The metabolic question
Insulin signalling, inflammation, and the case for a gastric workup before the next medication trial.
B12 that won't hold
Low B12 in adults who are supplementing — intrinsic factor, atrophic gastritis, and the workup most miss.
The rosacea workup
Vasoactive peptides, telangiectasia, and a peer-reviewed link the dermatology workup rarely tests for.

A protocol with a diagnostic step, not a guess.
Welyon's investigation is sequenced like a clinical workup. Test for the organism. Read the relevant guide. Engage the supervised protocol — only if indicated.
Test at home
A non-invasive at-home stool antigen test — the same test gastroenterologists order. Mailed back in the prepaid pouch; results in 5–7 days.

Match your symptom to one of eight condition guides. Each grades the evidence, names the mechanism, and lists the next clinical questions to bring to a physician.
Engage the Foundation Protocol
If the test returns positive and the guide is relevant, you're routed to a physician-supervised treatment protocol — eradication, follow-up testing, and condition-specific monitoring.
Skeptic-first. By design.
A research brand has to be auditable. These are the four artifacts that, together, separate Welyon from a wellness pitch: an advisory board, a registered trial, an evidence grading rubric, and a clear commercial interest disclosure.
Clinicians and researchers, named publicly
Welyon is assembling a scientific advisory board with expertise in gastroenterology, infectious disease, and evidence-based medicine. Advisor names and affiliations will be listed here upon confirmation.
In formation · 2026A registered trial, before launch
The Foundation Protocol will be registered on ClinicalTrials.gov prior to commercial availability. Registration ID will appear here, alongside the primary endpoints and the pre-registered analysis plan.
Registration pendingThree tiers, plainly labelled
Every claim across the eight guides is tagged with one of three evidence tiers, defined transparently below. No claim leaves a guide ungraded.
What Welyon sells
Welyon produces the testing kit and the Foundation Protocol referenced in these guides. The guides are commercial publications. We disclose this on every guide cover, every checkout page, and in the footer of this site. The guides remain the same whether or not you proceed.
Disclosed · Every surfaceAre you a clinician?
A separate page covers the test specifications, the supervised protocol's clinical scaffolding, the evidence base in long form, and the partnership model for primary care, GI, dermatology, and rheumatology practices considering an investigation referral pathway.
