I want to explain something that changes how a lot of people think about their autoimmune diagnosis.
Your immune system is supposed to work like a disciplined army — defend against real threats, leave your own body alone. Mold, and the chemicals it makes, throw that army into disarray. Sometimes that leaves you under-defended. Sometimes it leaves the immune system firing at the wrong target, which is your own tissue. That's autoimmunity.
Here's a detail most people have never heard. One of the mold toxins we look for on a urine mycotoxin panel — mycophenolic acid — is the same compound that's given as a medication to purposely suppress the immune system. Mold makes it all on its own. So when I say mold can suppress immunity, I don't mean it vaguely.
Then there's the gut. My view, after years of treating autoimmune patients, is that autoimmune conditions begin in the gut. And the gut happens to be one of the two places mold likes to set up camp inside you (the sinuses are the other). The place that drives immune confusion and the place mold colonizes are often the same place.
This is why I don't accept "it's genetic, you'll be on this forever" as the end of the story. Genes load the gun, but something pulls the trigger. And a trigger can be removed.
The order matters: get out of the exposure first, clear the mold, restore the gut. Along the way, immune-supporting therapies can help — the peptide thymosin alpha-1 is one we use to support the immune system while it recovers. When the trigger is gone, the immune system has a real chance to calm down.
If someone you love has an autoimmune diagnosis and no one has ever asked about mold or water damage, please share this with them.
This isn't a prescription — work with your doctor.
