Billionaire biohacker Bryan Johnson, known for his extreme anti-ageing protocols, has claimed that people are 'pleased' he has been diagnosed with an incurable autoimmune condition. The 48-year-old American entrepreneur, who spends millions annually in a quest to reverse his biological age, revealed last week that he has autoimmune gastritis (AIG), a chronic condition where the immune system attacks stomach lining cells.
Social media reaction to diagnosis
In a lengthy post on X, Johnson described the global reaction to his diagnosis, noting that while some expressed sadness, joy dominated the commentary. 'The world wants me to die,' he wrote. 'My incurable disease diagnosis became global news. It was omnipresent on social media and 1,900 articles were written in a matter of days. Many were saddened. However, joy dominated the commentary.' He added that 'there is a special place in people's hearts that loves to see others fail, especially when that person's presence threatens their own psychological stability.'
Johnson's anti-ageing regimen and costs
Johnson spends approximately $2 million (£1.5 million) per year on his anti-ageing protocols, including a team of 30 physicians, regular MRI scans, ultrasounds, and a strict vegan diet limited to 1,977 calories daily. He goes to bed at 8:30 PM and tracks his sleep quality and other biometrics. In 2023, Bloomberg reported he takes dozens of supplements daily and performs three high-intensity workouts weekly. He previously injected his 17-year-old son's plasma as part of his experimental treatments.
Details of autoimmune gastritis
Johnson revealed that he was diagnosed with hypothyroidism at age 21, which he managed for nearly three decades. In May 2026, he learned he also has AIG, a chronic inflammatory condition. According to the Global Autoimmune Institute, 0.5% to 4.5% of adults worldwide have AIG. Symptoms are often non-specific, leading to misdiagnosis or untreated cases, and can result in Vitamin B12 deficiency, anaemia, and an increased risk of gastric cancer. Johnson remains hopeful, stating: 'In the age of AI, multiomics, and custom-built DNA, proteins, and cells, no condition should be presumed incurable simply because no one has yet tried to cure it with today's stack.'
