Biohacker Bryan Johnson autoimmune disease diagnosis has added a sharp complication to his long-running project of trying to slow, measure and generally negotiate with ageing. In an interview with TMZ's Charlie Neff, Johnson discussed having autoimmune gastritis, an incurable condition he disclosed on social media last week.
This diagnosis adds some obvious irony, which Johnson seems perfectly willing to acknowledge. This is, after all, a man whose public identity is built around aggressive longevity protocols, biological tracking and the idea that decline should at least have to submit paperwork before proceeding.
What Bryan Johnson says he has been diagnosed with
Johnson said he has autoimmune gastritis, a chronic autoimmune disease affecting the stomach. According to his account, the condition has likely been developing quietly for 10 to 20 years.
He said the disease has left him unable to properly absorb iron, vitamin B12 and other micronutrients. That matters because those nutrients are not decorative. They are central to blood health, nerve function and basic nutrition. Johnson said the long-term consequences can include nutritional deficiency and, in some cases, cancer risk.
He described the condition as incurable, but not as a reason to retreat from his anti-ageing work. His reaction, as he put it, was that the diagnosis is "wondrous." That is not the standard response to a serious medical finding, but Johnson has rarely been in the business of standard responses.
