The disease can affect the production of stomach acid and interfere with the absorption of nutrients, including iron and vitamin B12. It may also progress for years with few or no obvious symptoms.Johnson said his diagnosis followed years of persistently low ferritin levels — an indicator of the body’s iron stores — that had not been fully explained despite extensive health monitoring. The condition was confirmed after further medical investigations, including blood tests and biopsies.He has previously said that he spends millions of dollars annually on efforts to improve his health and reduce his biological age. His regimen has included extensive blood tests, medical scans, strict dietary plans and experimental interventions, turning his own body into what researchers have described as an “N-of-1” experiment — a long-running study involving a single participant.Despite years of intensive testing and health optimisation, the condition appears to have developed quietly and remained undetected until further investigation was carried out. Medical experts say the case illustrates the limits of even extensive health tracking, particularly when a disease progresses slowly and produces few clear symptoms.Johnson has previously said he intends to closely monitor the condition and explore potential treatments. Autoimmune gastritis currently has no cure, although its effects and possible complications can be managed through medical monitoring and treatment.About the AuthorTrisha BhattacharyaTrisha Bhattacharya is a Senior Content Producer at Livemint, with over two years of experience covering entertainment news from India and beyond.
