- Bryan Johnson recently shared that he has an incurable autoimmune disease where his stomach is eating itself.
- The 48-year-old wrote that he would try and solve the condition, which he says only 2 to 5% of people have.
- Johnson's body began developing an autoimmune process that affected his thyroid and stomach lining — autoimmune gastritis (AIG).
- Standard medical care concedes defeat, stating that nothing can be done except managing the condition.
- Blood results showed elevated levels of anti-parietal-cells-antibodies, which pointed towards AIG.
- Stomach biopsies showed early weakening of the stomach lining — clear early signs of autoimmune gastritis.
- While autoimmune gastritis cannot be cured, it can be managed via B12 injections or iron infusions, the latter of which Johnson received a 1,000 mg Monoferric iron infusion.
- Johnson has a plan to routinely monitor several diagnostics, including ferritin, iron, B12, and chromogranin A, and will perform repeat biopsies.
Biohacker Bryan Johnson, 48, has disclosed his battle with incurable autoimmune gastritis (AIG), a rare condition affecting only 2-5% of the population. Johnson stated, "my stomach is eating itself," as he shared his diagnosis and treatment plan.1367
His autoimmune process has impacted both his thyroid and stomach lining, leading to significant health challenges. Medical evaluations revealed elevated levels of anti-parietal-cells-antibodies and stomach biopsies indicated early signs of AIG, including a weakening stomach lining.5
Despite the lack of a cure, Johnson is determined to manage his condition through B12 injections and iron infusions. He recently received a 1,000 mg Monoferric iron infusion and has devised a comprehensive monitoring plan that includes tracking ferritin, iron, B12, and chromogranin A levels. His team will also conduct repeat biopsies and explore experimental treatments based on diagnostic results.8
Johnson's case highlights the limitations of standard medical care, which often concedes defeat, stating that nothing can be done except managing the condition. He remains hopeful, stating he will “try and solve [the condition].”24
“Johnson's blood tests revealed elevated anti-parietal-cells-antibodies, pointing to autoimmune gastritis, and stomach biopsies confirmed early signs. He has since received a 1,000 mg Monoferric iron infusion and plans routine monitoring of ferritin, B12, and gastrin.”
