Bryan Johnson, a billionaire venture capitalist and prominent biohacker known for his unconventional approaches to longevity, has revealed that he has been diagnosed with autoimmune gastritis, a chronic and incurable condition in which the immune system attacks the stomach lining. The diagnosis marks a significant development for Johnson, who has spent years pursuing extreme methods in the hope of extending his lifespan and improving his health.

Johnson, 48, has gained attention in recent years for undertaking unusual and costly treatments aimed at combating the effects of aging. These measures have included experimental procedures such as injecting himself with his son’s blood plasma. He has publicly expressed ambitions to "conquer death" and has previously claimed to have the physical health comparable to that of an 18-year-old. His biohacking efforts are reported to have cost around £7.5 million.

In a post on the social media platform X, Johnson appeared to question the trajectory of his longevity quest following his medical diagnosis, writing that he has been reflecting on whether he has "taken this whole longevity thing too far." Johnson has also sparked controversy by asserting that he has created a clone of himself as a newborn baby, purportedly to serve as a source for harvesting organs, although details of this claim remain unverified.

Autoimmune gastritis is a progressive condition that can lead to significant digestive difficulties and increases the risk of developing stomach cancer. There is no known cure, and treatments typically focus on managing symptoms and preventing complications.

Johnson’s announcement highlights the challenges and uncertainties faced by individuals experimenting with cutting-edge biohacking technologies in the pursuit of life extension. Despite his financial resources and ambitious goals, his diagnosis underscores the limits of current medical science in reversing or halting certain autoimmune disorders.
