Biohacker and entrepreneur Bryan Johnson has revealed an ambitious research plan to try to cure his autoimmune gastritis, describing it as an approach that, according to his team, has never before been attempted for an autoimmune disease.
In a post on X, Johnson said he was diagnosed with autoimmune gastritis (AIG) in May after doctors identified the condition through a stomach tissue biopsy. He explained that the disease causes the immune system to mistakenly attack the stomach lining, reducing the body's ability to absorb nutrients such as iron and vitamin B12 and potentially increasing the risk of stomach cancer over time.
