If you have POTS or another form of dysautonomia, you’ve probably been told to increase salt, push fluids, wear compression, and maybe try a medication or two. That advice isn’t wrong, but it’s…
Spencer ZimmermanHostSo what causes POTS? Now, I think it's important to understand that there's a difference between what causes POTS and what keeps it going.
But just because something acts as a trigger doesn't mean that's the issue, right? Like you come out of surgery, it's not like you're still in surgery.
Like if you're not acutely sick anymore, but you're still struggling, is it the fact that you still have something you have to remove from the body? Or is it the fact that it dysregulated something? Now, what a lot of people are really looking for is low blood volume is kind of the central mechanism that a lot of people really focus on.
And I think this is partly due to the fact that a lot of the people leading different pots.
And so they're thinking about circulation because we do know in POTS, you're not getting enough blood flow back to the heart and you're also not getting enough blood flow to the brain.
Many of you, unfortunately, you have to fight to get this type of autonomic testing with biopsies and QSART testing, which is basically a sweat analysis test saying, okay, you know what, we put this stuff on you.
Do you have appropriate sweat or is there likely nerve issues? Mass cell activation syndrome is a big player here.
This can also lead to vasodilation and increase the POTS-related symptoms and your lack of function.
As much as I like the vestibular system, I would never, ever ignore mass cell activation syndrome when it's present.
But it also doesn't mean you treat mast cell and all of a sudden your POTS goes away.
This is where having an integrative approach, as we'll talk about later, is critically important.
