Overview
- Johnson said he was formally diagnosed in May after months of testing and that he discovered the condition while investigating long‑standing low ferritin levels.
- His medical workup included a clean colonoscopy, a bi‑directional endoscopy, blood tests showing elevated anti‑parietal‑cell antibodies, and stomach biopsies that found early atrophy of the acid‑producing lining.
- He has begun standard symptom management, including a reported 1,000 mg Monoferric iron infusion and plans for B12 and iron replacement as needed.
- Johnson and his team plan deep immune profiling, repeat biopsies, T‑cell and cytokine analyses, and development of experimental interventions such as engineered cell therapies and AI‑designed antibodies, which he says he will document publicly.
- Autoimmune gastritis currently has no approved cure, can cause iron and B12 deficiency and raise gastric cancer risk, and Johnson’s high‑resource, public effort may draw scientific interest and scrutiny of experimental approaches.
