Bryan Johnson Discovers His Stomach Is 'Eating Itself'

Bryan Johnson's Diagnosis

According to Главком: American biohacker and entrepreneur Bryan Johnson has announced he has been diagnosed with autoimmune gastritis, a chronic inflammatory condition affecting the stomach lining. Johnson attributes the onset of the disease to poor lifestyle habits during his childhood, as well as ongoing stress from building his career and raising three children. The diagnosis was confirmed in May 2026, following a history of other chronic conditions-most notably, at age 21, he was diagnosed with a chronic inflammatory thyroid disorder.

Consequences and Treatment Search

In his early twenties, Johnson was in good health, but he later gained roughly 18 kilograms of excess weight due to a sedentary lifestyle and poor diet. He admits that as a child, he consumed large amounts of sweets, soda, and fast food. This eventually triggered an autoimmune process that led to the development of autoimmune gastritis.

“The bad news No. 1: my stomach is eating itself. The bad news No. 2: 2-5% of people also suffer from this disease. There are probably more, because the condition is often hidden. The good news: I’ll try to find a way to overcome it. And I will definitely share everything,” - Bryan Johnson.

Autoimmune gastritis comes with serious health consequences, including nutrient deficiencies, anemia, and an elevated risk of developing cancer. Johnson emphasizes that “when it’s detected, standard medicine admits defeat, saying nothing can be done except to manage the course of the disease, no matter how terrible or deadly the outcome may be.”

In his search for ways to combat this incurable condition, Johnson plans to explore innovative approaches, including:

• gene therapy using the protein follistatin;
• stem cell injections.

He has already undergone gene therapy and spends roughly 1.9 million euros per year on various anti-aging treatments. Johnson takes more than 50 pills daily and has a team of 30 specialists assisting him in his health optimization efforts.

Bryan Johnson's diagnosis of autoimmune gastritis highlights how lifestyle choices can have lasting effects on health. His case serves as a reminder that even with career success and financial independence, health problems can arise from neglecting one's well-being during youth. Given the severity of the condition, it is crucial that more people pay attention to the signs and symptoms that may indicate autoimmune diseases.

In light of Bryan Johnson's recent health challenges, it's important to note that this isn't the first time he has faced significant medical issues. After investing heavily in anti-aging treatments, he has now uncovered another serious condition.
