Bryan Johnson reveals autoimmune gastritis diagnosis and credits health focus for better outcomes

Biohacker Bryan Johnson, known for his ultra-regimen “Don’t Die” approach, disclosed that he has autoimmune gastritis, a condition linked to a prior autoimmune thyroid disease, and said his health-focused changes over the past five years would have prevented a much worse outcome. He also shared that he had long suffered iron deficiency due to the condition and received IV iron treatment. Johnson, who has faced criticism for his extreme lifestyle, defended his choices while noting that his diet and sun exposure may have contributed to his autoimmune issues, and he pledged to document his ongoing efforts to extend health and longevity.
