American tech entrepreneur and biohacker Bryan Johnson, known for his extreme anti-aging regimen, has revealed he was diagnosed with autoimmune gastritis (AIG) in May 2024. The condition, which causes the immune system to attack the stomach lining, was discovered after months of medical testing to investigate his iron deficiency.
Johnson, 48, shared the diagnosis on Instagram, stating, 'My stomach is eating itself.' He has spent years and millions of dollars on longevity treatments, aiming to live until 2140.
Core Facts and Diagnosis
Johnson’s diagnosis came after years of health struggles, including hypothyroidism since age 21 and a period of chronic depression in his 30s. He attributed his declining health to poor diet and stress during his early career and fatherhood. AIG, a chronic condition, can lead to nutrient deficiencies, anemia, and an increased risk of stomach cancer if untreated.
Medical Background and Treatment
Autoimmune gastritis affects 2% to 5% of adults worldwide, though Johnson suggested the true prevalence may be higher due to its often hidden symptoms. The condition impairs the stomach’s ability to absorb vitamin B12 and iron, leading to long-term complications. Johnson noted that early symptoms, such as abdominal pain and bloating, are often overlooked.
Johnson’s Response and Future Steps
Johnson has vowed to 'solve' the condition and plans to share updates on his treatment journey. He has previously undergone experimental therapies, including plasma exchange with his son, as part of his longevity efforts. His diagnosis highlights the challenges of managing autoimmune diseases, which often lack definitive cures and rely on symptom management.
Broader Implications
The case raises awareness about autoimmune diseases, which are often underdiagnosed due to vague symptoms. Johnson’s high-profile diagnosis may encourage others to seek early medical intervention for similar conditions.
