The diagnostic gap.
Why Welyon exists — in one paragraph, suitable for publication.
H. pylori infects approximately 44% of the global population. The peer-reviewed literature documents its association with iron deficiency anemia, B12 depletion, chronic fatigue, brain fog, thyroid autoimmunity, insulin resistance, chronic urticaria, and rosacea. These are not fringe hypotheses — several associations are supported by multiple randomised controlled trials and systematic reviews, with odds ratios that warrant clinical attention.
The problem is structural. H. pylori is classified as a gastric infection and managed by gastroenterologists. The eight conditions it associates with systemically are managed by hematologists, endocrinologists, neurologists, dermatologists, and primary care physicians. No standard clinical algorithm connects a gastric infection to these conditions across specialty lines. The result is that millions of patients with refractory iron deficiency, persistent fatigue, or unexplained thyroid antibodies receive years of symptomatic treatment for the downstream effect without ever being tested for the upstream cause.
Welyon is a research-publishing company. We produce peer-referenced investigation guides explaining each association, the specific biological mechanisms, the evidence tier, and the practical next steps — including what to ask your physician, how to read the test, and what recovery looks like after eradication. We also produce the H. pylori stool antigen testing kit and are developing the Foundation Protocol, a physician-supervised supplement regimen for patients who cannot tolerate or have failed antibiotic eradication.
We disclose our commercial interests on every guide cover, every checkout page, and throughout this website. The diagnostic gap is real regardless of whether anyone buys anything. Our position is that closing it begins with naming it.
