Man trying to live to 160 says his stomach is ‘eating itself’

July 7, 2026 | | Print Article

Amid lighthearted jokes that he’ll “probably die in an ironic way,” biohacker Bryan Johnson shared details about being diagnosed with an incurable disease he intends to “solve.”

As a serial entrepreneur, Johnson amassed wealth founding businesses like Braintree and Kernel, paving the way for his anti-aging endeavor Project Blueprint. Having shared his extreme protocols to conquer Father Time and stave off death, the noted biohacker more recently revealed, “My stomach is eating itself.”

Leading off a lengthy social media post, Johnson started with two points of “bad news” as he shared, “I have an autoimmune disease. My stomach is eating itself,” and, “2-5% of people have this, too. Likely more, because it hides.”

With those points in mind, the venture capitalist with a stated aim of living to be 160-years-old and surviving to the year 2140 added, “Good news: I’m going to try and solve it. Will share all.”

According to Johnson, he was diagnosed with autoimmune gastritis (AIG) in May, a condition in which the lining of the stomach is irreversibly damaged, impacting the body’s ability to absorb nutrients. As to why the disease went overlooked for 11 years despite his ongoing biohacking endeavor over the last five years, he faulted the previously diagnosed low ferritin levels.

“Low iron stores get normalized and rarely investigated at all when anemia hasn’t shown up yet. That blind spot is what hid mine for a decade,” he wrote before adding, “What I didn’t fully appreciate until recently is how many stones my previous providers had left unturned. The low ferritin kept getting explained away but not fixed.”

With a cure in mind, Johnson shared an image on Friday after having 33 tubes of blood drawn with the intention of “decoding 1 million immune cells” in his effort to find the cause of the AIG.

As he put it, “in the age of AI, multiomics, and custom-built DNA, proteins and cells, no condition should be presumed incurable simply because no one has yet tried to cure it with today’s stack.”

The endeavor extended beyond his health as Johnson has also been chronicling his Project Blueprint cofounder and girlfriend Kate Tolo’s own journey in biohacking, including extensive studies of her reproductive system, leading him to state on Thursday, “We have news on her suspected endometriosis. More soon. At least 20% of premenopausal women have at least one of these conditions: endometriosis, PMOS, and/or adenomyosis.”

In her thread in June describing her “skin age” as that of a 21-year-old, the 30-year-old wrote, “I am about to become the female equivalent of Bryan Johnson. Skin is cool and important but… we’re about to spend millions to measure and decode my biology through every phase of the menstrual cycle. I’ll be doing an unhinged measurement protocol… across blood, urine, stool, saliva, vaginal microbiome, urine, etc etc. Measuring multiple times a day.”

Concluding the post about his own health, Johnson insisted, “Care for yourself, care for others, care for the planet and care for our animal friends. Care for life, as it’s the most precious gift there is.”

As his latest update drew more attention, the biohacker showed a spike in followers on X with a list describing himself before noting, “i’ll probably did in an ironic way… i hope you enjoy.”
