Summary
Are your POTS symptoms being driven by a hidden nervous system imbalance?
In this episode, we dive deep into the root causes of Postural Orthostatic Tachycardia Syndrome, looking way beyond standard symptom management. Discover how chronic stress, adrenal burnout, and autonomic dysregulation trigger debilitating spikes in heart rate and fatigue. We break down the connection between your brain, adrenals, and vagus nerve, providing you with actionable, root-cause strategies to calm your nervous system, restore balance, and reclaim your vitality. (Note: Sorry for the quality of the recording! We'll work on it!)

| 0:00.0 | And we are live. It's out of the J. In The House with Evan Brand. Today we're going to be talking about post postural orthostatic tachycardia syndrome. We'll be talking about that and how it connects to your adrenals, to disautonomia, to electrolyse, and to your hormones. Again, this is not going to be medical advice. We're talking about upstream physiological imbalances and how they may connect |
| 0:21.4 | downstream to different symptom manifestation. Again, if you have, I think you have pot's |
| 0:25.3 | issued, please get analyzed by your conventional medical doctor first. We're just trying to |
| 0:29.3 | give you a little bit more info on the hormonal, biochemical, endocrinological root causes behind |
| 0:36.2 | us. Evan, how are we doing, my man? I'm doing good. You know, in the last five years, we've seen a huge rise in pots. We have people reaching out to us every week. I've seen social media videos. Yep, you've seen social media videos? Yep, it's pretty common. I mean, all over the place, right? TikTok, everywhere else. Go ahead. Yeah, so we hope to |
| 0:54.7 | unpack some of this for you and then give you some root cause strategies, things that you |
| 0:58.0 | could be looking into from a root cause perspective that, truthfully, some of them can be quite simple. |
| 1:03.9 | And I've had pots. I remember years ago, I was at my grandma's house helping to pick some |
| 1:08.2 | weeds. And I remember standing up and falling back. I mean, |
| 1:12.5 | this was many years ago, but just that level of faintness from standing, that huge decrease in |
| 1:18.3 | blood pressure, you literally can lose the oxygen to your brain. So this can be a bad situation, |
| 1:24.1 | especially if you're in the bathroom, you stand up out of the tub, the hot water plus the low blood pressure, you stand up, you hit your head on a toilet. I've heard that story before, and it's not pretty. Yeah, and biggest thing we look at with pots is, you know, where's your blood pressure at? So you can always do what's called the orthostatic hypotension test. You can get your blood pressure laying down, stand up, see where the blood pressure goes. It should actually go up, right? So when you're laying down, think about it, right? You got horizontal. Your heart does not have to pump as much because gravity is kind of evenly spreading out blood flow. When you stand up, now your heart rate has to go up. So blood pressure should go up to be able to perfuse to your brain. And so when you |
| 2:01.0 | change that body position, if you get dizzy, that's a sign that your heart is not and your nervous system is not compensating fast enough to get the butt up to the brain until you get dizzy. And so you can test your blood pressure, right? Put it on your arm, lay down, get your blood pressure. And then when you stand up, test it again right away, you should have a five or ten point increase. |
| 2:19.8 | If you have a decrease overall, that's a sign of dysotototonia, that your nervous is not adequately responding. Now, a couple things we can do is we can look at electrolytes. That's a big deal. You know, your potassium, your sodium, and your magnesium. We can also look at hydration. These are all important things. And then we can also look deeper at some of the hormones that control |
| 2:37.2 | those things, like the adrenal glands, especially the outer part, the glomerular physicularis, |
| 2:44.4 | which is the outer part of the adrenal gland that helps regulate your mineral corticoids |
| 2:48.2 | and helps make the hormones that help hold on to your electrolytes |
| 2:51.2 | called aldosterone. Yeah, I got really messed up with this years ago when I had mold exposure and three |
| 2:56.9 | tick bites in one summer, just getting to the top of a flight of stairs, standing up out of bed, |
| 3:02.6 | getting out of the car, getting up out of the bathtub, getting out of the sauna. I would just have |
| 3:06.8 | these different triggering events that I knew I had to be careful. Luckily, I never fully went to the ground or anything like that. But there were definitely times where I was like, wow, this is not good. I could imagine being elderly and this really turning into a bad issue where you fall, break a hip, something crazy. So I really, really think the biggest thing for me was the sauna and improving |
| 3:25.9 | my blood flow. Because when I had pots the worst, I think this is somewhat of a vascular issue as well. |
