Bryan Johnson has been open about his struggles with low iron levels, which he has been experiencing for 11 years. Despite following a longevity protocol and consuming meat, his ferritin levels remained low, averaging 38 ng/mL. Johnson's condition, autoimmune gastritis, is a key factor in his low iron levels. This condition occurs when the immune system attacks the stomach's acid-producing cells, leading to improper iron absorption.
Autoimmune gastritis is driven by immune dysfunction and genetics, rather than diet or lifestyle. As a result, individuals with this condition may experience persistent iron deficiency, fatigue, brain fog, and eventually vitamin B12 deficiency if left untreated. Gastroenterologists emphasize the importance of medical evaluation for unexplained low ferritin or recurring iron deficiency, as healthy habits alone cannot prevent autoimmune diseases.
Johnson's experience highlights the complexity of the human body and the need for comprehensive medical evaluation. His condition prevented proper iron absorption, making intravenous iron infusion the only effective treatment. This underscores the importance of seeking medical attention for persistent health issues, rather than relying solely on diet and lifestyle changes.
The relationship between autoimmune gastritis and iron deficiency is well-established. When the immune system attacks the stomach's acid-producing cells, it can lead to a decline in the production of intrinsic factor, a protein necessary for vitamin B12 absorption. This, in turn, can cause iron deficiency and other nutritional deficiencies.
Experts stress that unexplained low ferritin or recurring iron deficiency should be medically evaluated. This is because autoimmune diseases, such as autoimmune gastritis, can have a significant impact on overall health and well-being. By seeking medical attention, individuals can receive a proper diagnosis and treatment, which can help alleviate symptoms and prevent long-term complications.
In Johnson's case, his low iron levels were finally addressed through intravenous iron infusion. This treatment allowed him to boost his ferritin levels back to healthy levels, highlighting the importance of seeking medical attention for persistent health issues. By sharing his experience, Johnson hopes to raise awareness about the importance of medical evaluation and the need for comprehensive treatment.
Overall, Johnson's story serves as a reminder of the complexity of the human body and the importance of seeking medical attention for persistent health issues. By prioritizing medical evaluation and treatment, individuals can take a proactive approach to managing their health and preventing long-term complications.
