Welyon publishes investigation guides, manufactures a non-invasive testing kit, and is developing a physician-supervised protocol. It exists because the literature on H. pylori has moved faster than the standard workup.
Roughly one in three Americans carry H. pylori. The peer-reviewed literature has — slowly, across thirty years — associated this single bacterium with eight clinically distinct presentations, from refractory iron deficiency to chronic spontaneous urticaria. The mechanisms are increasingly characterised. The literature is publicly available. The diagnostic step required to act on it costs less than a single visit to a specialist.
And yet the standard workup for most of those eight conditions only tests for H. pylori when the symptom is digestive — with the notable exception of ITP, where H. pylori testing is guideline-endorsed by the American Society of Hematology.
That is the whole project. Welyon does not invent mechanism, does not promise resolution, does not sell a wellness lifestyle. It publishes what the literature already says, gives readers the language to ask sharper questions, and stands behind a testing pathway when the conversation calls for one.
The investigation series spans claims that are well-replicated and claims that are early-stage. Treating those two categories with the same visual weight would be a trust failure. So we don't. Every claim across the eight guides carries one of three tiers — Strong, Moderate, or Exploratory — applied inline at the point of claim, and again in the citation list at the back of the PDF.
The rubric is applied identically regardless of whether the resulting investigation routes a reader toward — or away from — Welyon's testing kit and protocol. Editorial grading is independent of commercial outcome. That independence is the trust contract.
Multiple peer-reviewed studies in agreement; replicated in independent cohorts; mechanism characterised. The case for investigating is well-established.
Consistent literature, but cohort scale is limited or the mechanism is only partially characterised. The case is plausible and worth pursuing as part of a structured workup.
Plausible mechanism with early-stage or pilot-cohort evidence. The case for investigating, not the case for concluding. Flagged honestly on the cover and inline.
Welyon is developing an at-home H. pylori testing kit, the Welyon HP Stack, and the Welyon HP Program. The presence of this disclosure does not change the content of the guides. This commercial interest is disclosed on every guide cover, every checkout page, and in the footer of this site.
Evidence grading across the series follows a single rubric, applied identically regardless of whether the resulting investigation routes a reader toward — or away from — Welyon's testing kit or protocol. No claims are softened or strengthened for commercial benefit.
