Bryan Johnson says his stomach is ‘eating itself’: What is AIG?

I had just a few wholesome years in my early 20s, however then turned a younger father of three and started constructing a enterprise. Juggling that stress and grind, I let my well being slip and gained 40 lbs. Inside just a few years, I’d fallen right into a deep, continual melancholy. Someplace in that timeline, my physique started creating an autoimmune process affecting my thyroid after which my abdomen lining. It’s known as Autoimmune Gastritis (AIG). My hypothyroidism obtained identified once I was 21 years outdated with a routine blood draw. That enabled me to start proactive administration, supplementing levothyroxine and Armour Thyroid.

Wanting again over the previous few years, I can now see the early indicators we had been choosing up in measurement however hadn’t related the dots. For 11 years, I’ve had low ferritin, with out anemia. We regularly tried to lift my iron ranges with meals and supplementation however nothing would work. We chased the plain options first. A plant-based food plan means all my iron is the hard-to-absorb, non-heme type. Exhausting coaching, sauna, and hyperbaric oxygen all elevate the physique’s demand for iron. However none of them defined the core failure: regardless of me taking iron orally, trialing each formulation, and utilizing each timing trick, not one of the iron would stick.”
