In the United States, Bryan Johnson, a 48-year-old tech entrepreneur, announced on July 7, 2026, that he has been diagnosed with autoimmune gastritis following a bidirectional endoscopy. This condition, which leads to the destruction of stomach cells, is chronic and currently has no known cure. Johnson, who gained fame for his extensive biohacking efforts aimed at achieving immortality, expressed optimism about his diagnosis, stating that he views it as an opportunity to explore potential solutions not only for himself but for millions of others affected by the same condition. Johnson's journey into biohacking began after he sold his company, Braintree, which included Venmo, to PayPal for $800 million in 2013. Since then, he has invested millions into various health and longevity initiatives, including developing products like a longevity mix and essential microbiome supplements. His commitment to living longer and healthier has garnered him a significant following on social media, where he shares insights and updates about his health journey. He has also been featured in a Netflix documentary titled "Don't Die: The Man Who Wants To Live Forever," which chronicles his quest for longevity. Despite the challenges posed by his recent diagnosis, Johnson remains undeterred. He has previously dealt with autoimmune issues, having been diagnosed with autoimmune hypothyroidism at the age of 21. He noted the connection between thyroid health and stomach health, emphasizing that when one is affected, the other often follows. Johnson's proactive approach to health diagnostics reflects his belief that early detection is crucial for better health outcomes. In his social media posts, Johnson has encouraged others to embrace their health challenges rather than shy away from them. He believes that understanding one's health conditions can lead to better management and potential breakthroughs in treatment. Johnson's team is currently exploring various avenues to find a cure for autoimmune gastritis, and he hopes that their efforts will contribute positively to the broader medical community. He expressed gratitude for the support he has received since his diagnosis and remains hopeful about the future, both for himself and for others facing similar health issues.
