Bryan Johnson Diagnosed With Autoimmune Gastritis, Calls Health Regimen a Mitigating Factor

Longevity-obsessed biohacker Bryan Johnson has been diagnosed with autoimmune gastritis, an incurable condition that can deplete iron and vitamin B12.

Bryan Johnson, the tech entrepreneur who spends roughly $2 million a year pursuing what he calls the goal of 'not dying,' has been diagnosed with autoimmune gastritis — a chronic, incurable condition in which the immune system attacks the stomach lining. The diagnosis was disclosed by Johnson himself, who spoke to The Independent about it. Autoimmune gastritis is known for causing persistently low levels of iron and vitamin B12, both of which are critical to energy and neurological health. The condition has no cure, though its effects can be managed. Johnson told The Independent he believes the outcome 'would be much worse' had he not spent the past five years intensively focused on his health, adding that he is 'very grateful to have been focused on health.' Johnson rose to public prominence through his 'Blueprint' protocol, an extreme regimen of diet, sleep, exercise, and dozens of daily supplements designed to slow or reverse biological aging. Yahoo Health consulted two medical experts on how the diagnosis might affect his broader longevity goals, though neither source detailed their conclusions at length.

Why it matters

The diagnosis presents a notable complication for Johnson's high-profile longevity project, as autoimmune gastritis directly undermines the nutrient absorption his intensive health regimen depends on. It also raises broader public questions about the limits of even the most aggressive preventive health efforts.

What's next

Johnson has not publicly outlined how he plans to adjust his health protocol in response to the diagnosis.

Key facts

• Bryan Johnson has been diagnosed with autoimmune gastritis, a chronic condition with no known cure.
• Autoimmune gastritis causes the immune system to attack the stomach lining, leading to iron and vitamin B12 deficiencies.
• Johnson told The Independent the condition 'would be much worse' if he had not prioritized his health over the past five years.
• Johnson's longevity regimen is reported to cost approximately $2 million per year.
• Yahoo Health consulted two medical experts to assess the diagnosis's impact on his longevity goals.
• Johnson publicly disclosed the diagnosis himself, speaking exclusively to The Independent.

Bias & framing notes

Yahoo Health's headline emphasizes the irony of a 'man who wants to live forever' receiving an incurable diagnosis, framing the story around contradiction and drama. The Independent's coverage, based on an exclusive interview, gives Johnson more direct voice and a sympathetic framing, highlighting his gratitude for his health regimen. Neither source provided substantial independent medical analysis of the diagnosis's severity or long-term implications.
