Bryan Johnson, a 48-year-old biotech entrepreneur and self-described “biohacker,” has revealed that he’s been diagnosed with an autoimmune disease, shocking fans who followed his aging-defying journey documented in the 2025 Netflix docu-series Dont Die: The Man Who Wants to Live Forever.
Johnson, who claims to be on a mission to live “multiple lifetimes,” made the announcement on social media, stating that his stomach is “eating itself” due to the autoimmune condition. Autoimmune diseases, where the body’s immune system mistakenly attacks healthy tissues, can be debilitating and, in severe cases, life-threatening.
Biohacking Fails to Halt Disease Progression
Johnson’s diagnosis has raised questions about the efficacy of his biohacking methods, which involve using technology and experimental treatments to manipulate his body’s aging process. His regimen includes a range of unconventional techniques, from intermittent fasting to parabiosis (a process where the blood of young animals is injected into his body). Despite these efforts, Johnson’s autoimmune disease has progressed undeterred.
Autoimmune Disease and the Role of AI
While AI has made significant strides in medical research and diagnosis, its impact on treating autoimmune diseases is still largely in its infancy. However, researchers are exploring AI-powered tools that can help identify potential triggers and monitor disease progression. This could potentially lead to more personalized treatment plans and improved patient outcomes.
What This Means for Biohacking Enthusiasts
Johnson’s diagnosis serves as a reminder that, no matter how hard we try to defy aging or manipulate our biology, our bodies are still subject to the unpredictability of disease. For those who’ve been inspired by biohacking, his story highlights the importance of factoring in the risk of adverse health outcomes and not being seduced by the promise of quick fixes or overnight transformations.
Johnson’s journey will undoubtedly continue to captivate audiences, but it’s essential to approach his story with a nuanced understanding of the complexities involved. By acknowledging the limitations of biohacking and the unpredictability of autoimmune diseases, we can move toward a more informed and compassionate discussion about the intersection of technology and human health.
