Anti-ageing millionaire Bryan Johnson, the tech entrepreneur famous for spending nearly $2 million a year to reverse ageing, has revealed a devastating health battle that even his obsessive wellness routine couldn't prevent. The 48-year-old disclosed that he has been diagnosed with autoimmune gastritis (AIG)—a rare condition in which the body's immune system attacks the stomach lining.
In a candid post on X, Johnson stunned followers by writing: "I have an autoimmune disease. My stomach is eating itself." He warned that the illness often develops silently, affecting an estimated 2-5% of people, and can lead to iron deficiency, anaemia and even an increased risk of stomach cancer if left undetected.
