POTS - when your body panics just from standing up.
POTS isn't about being dizzy sometimes. It's a nervous system that can't regulate blood flow and heart rate the way it should - and a life you have to build around that. If you live with it - or love someone who does - this page is for you.
A resource for people with POTS and dysautonomia - and the people who love them.
What is POTS?
POTS stands for Postural Orthostatic Tachycardia Syndrome. In plain words: your body doesn't know how to stand up properly anymore.
When most people stand, their blood vessels tighten to push blood back up to the brain. With POTS, that system doesn't respond in time. Blood pools in your legs, your heart races to compensate - sometimes jumping 30, 40, 50 beats a minute - just from standing still.
It doesn't show from the outside. You look like you're just standing there. Meanwhile your heart is working like you're running up a hill.
The pain isn't only physical. It's standing in a grocery store line and feeling the room tilt. It's learning to read your own warning signs before you hit the floor.
POTS is real. Even when it just looks like someone standing in a kitchen.
POTS Symptoms
People with POTS can experience a wide range of symptoms, especially when standing or staying upright. Here are the main ones:
Racing heart on standing: Heart rate jumps 30+ beats per minute (or over 120 bpm) within ten minutes of standing up.
Dizziness and lightheadedness: A floating, unsteady feeling that gets worse the longer you're upright.
Brain fog: Trouble thinking clearly, especially right after standing, when blood flow to the brain briefly drops.
Fatigue and exercise intolerance: Exhaustion that's disproportionate to what you actually did, and a body that reacts badly to exertion.
Fainting or near-fainting: Actually passing out, or the grey-out, ringing-ears feeling right before it.
Temperature and digestive issues: Trouble regulating body heat, nausea, and other gut symptoms tied to the same nervous system malfunction.
What actually happens in the body
POTS is a form of dysautonomia - a malfunction in the autonomic nervous system, the part of you that's supposed to run on autopilot. Heart rate, blood pressure, digestion, temperature - all the things you never had to think about.
The core problem is blood flow regulation. When you stand up, gravity pulls blood down into your legs and abdomen. In a working system, blood vessels constrict instantly to push it back up. In POTS, that reflex is too slow or too weak. Blood pools below the waist, less of it reaches your brain, and your heart tries to fix the shortfall the only way it knows how - by beating faster. Sometimes much faster.
It's often tangled up with other things. Many people with POTS also have Ehlers-Danlos Syndrome (looser connective tissue means blood vessels stretch more than they should) or Mast Cell Activation Syndrome (an immune system that overreacts to normal triggers). The three show up together often enough that doctors have a name for the pattern.
Then there's the blood volume problem. Many people with POTS are also running with less blood volume than they should have. Less fluid in the tank means the heart has to work harder for the same job. It's not anxiety making your heart race. It's math.
What can trigger it
POTS doesn't usually appear out of nowhere. Something tips an already-strained system over the edge.
Viral infection. A bad virus - mono, a nasty flu, COVID - can leave the autonomic nervous system unable to reset. This is one of the more common stories in the long COVID world right now.
Puberty and hormonal shifts. POTS shows up disproportionately in teenage girls and young women, often right around puberty, pregnancy, or major hormonal changes.
Surgery or physical trauma. A major surgery, a bad injury, or a long period of bed rest can be enough to knock the system out of its normal rhythm.
Underlying connective tissue conditions. For people who already have looser connective tissue (like EDS), the blood vessels don't do their job as well to begin with - which makes the system more likely to tip into POTS under stress.
How is it diagnosed?
There's no single blood test that says 'you have POTS.' What doctors actually do is watch what your heart rate and blood pressure do when you go from lying down to standing. And there's more than one way to do that.
The simple version is called an active stand test: you lie down for a few minutes, they measure your heart rate and blood pressure, then you stand - and they measure again, every few minutes. It's cheap, it can be done in almost any clinic, and it's usually where they start.
Then there's the tilt table test - the more formal version. And it's exactly as unpleasant as it sounds. You get strapped to a table. Actually strapped - straps across your chest and legs, so you can't cheat by shifting your weight or clenching your muscles to help your blood flow (which is exactly what your body wants to do). Then the table tilts you upright, and you stay there, still, while they watch your heart rate and blood pressure for anywhere from ten to forty-five minutes.
I did it. It's genuinely one of the worst things I've been through medically - and I've been through a lot. Your heart starts pounding, the room starts sliding sideways, and you're not allowed to move to make it stop. You just have to stay there and let your own nervous system fail in front of a monitor.
Either way, they're looking for the same thing: a heart rate increase of 30 beats per minute or more within ten minutes of standing (40 for teenagers), without a big drop in blood pressure - that's what separates POTS from simple fainting. And along the way, doctors rule out other things that can look similar, because POTS is a diagnosis you reach after other causes are off the table.
The Treatment Gap
There's no cure for POTS. What there is, is management - and most of it comes down to giving your circulatory system more to work with.
More salt. More fluids. Doctors often say 3 liters of water and 10 grams of salt a day, which sounds insane until you understand it's literally increasing your blood volume so your heart doesn't have to work as hard. Compression garments - the tight, waist-high kind, not ankle socks - do a similar job by physically stopping blood from pooling in your legs.
Sometimes there are medications: beta blockers to slow the racing heart, or drugs that help blood vessels constrict properly. They help some people a lot. They don't fix the underlying wiring.
The exercise advice is where it gets complicated. "Just exercise" is technically true - recumbent exercise, done slowly and built up over months, genuinely helps retrain the system. But telling someone with POTS to "go for a run" without the recumbent, gradual, monitored version is a good way to send them to the floor. The gap between the advice and the actual protocol is where a lot of people get hurt trying to help themselves.
I know some of this from the inside
I don't have a POTS diagnosis. What I do have is vasovagal symptoms - the kind of fainting-adjacent, blood-pressure-drops-when-I-stand-too-fast experience that lives in the same neighborhood - and comorbid symptoms that overlap with a lot of what people with POTS describe to me.
So when I say I understand the standing-up-and-the-room-tilts feeling, or the doing-the-math-before-you-move feeling (can I stand from this chair right now, or do I need thirty seconds first) - I mean that literally, not as a metaphor.
What I've noticed, both from my own body and from years of working with people who do have POTS: the thing that actually helps is the same thing that helps with every one of these illnesses. There's no cure. There's pacing, and there's learning to work with a nervous system that doesn't do what you'd expect, instead of fighting it.
I bring what I've lived, and what I've learned from people who live with more of this than I do. Those aren't the same thing. But they talk to each other.
What POTS means day to day
POTS isn't just dizziness. It changes everything. Here are the things people who don't live with it don't always understand:
- Standing still is often harder than walking - blood pools more when you're not moving
- Brain fog shows up hardest right after you stand up, when your brain is briefly running on less blood
- Hot showers, hot weather, and standing in line are not small things - they're real triggers
- Your heart rate can look like you're mid-workout while you're just making coffee
- People don't always believe you because you don't look sick, and your labs often come back normal
- Some days you can stand for an hour. Some days thirty seconds. You can't always predict which
- Sitting down fast, or lying down with your legs up, isn't dramatic - it's what actually helps
- Medical treatment matters - but it doesn't address who you are now. That's what we work on.
POTS in coaching
People with POTS who come to coaching aren't usually looking for another tip about salt tablets or compression socks. They've got those. They've read the forums.
What they're looking for is something else.
Space for the questions that don't have a medical answer. Who am I, when my own body makes standing up a calculated risk? What do I still want to do, and what am I willing to plan around instead of push through?
These aren't questions a cardiologist can answer. They're identity questions.
My coaching works within your reality, not outside of it. No expectations that assume you can just stand in a line for twenty minutes because most people can. Everything is adapted - the pace, the tools, whether we meet lying down.
We don't work on getting your old body back. We work with the one you have now.
A conscious decision - not a surrender - about what to spend your standing-up-minutes on. That's what we do together.
If you love someone with POTS
POTS is hard to explain, especially because it comes and goes. Even to people who really want to understand.
If someone you love lives with POTS, here's what matters:
When they sit down suddenly in the middle of a conversation - that's not rudeness, that's their body telling them to get horizontal before it makes the decision for them. When they seem fine sitting and then go pale standing up - both are real, at the same time. When they could stand through a whole event last week and can't make it through the kitchen today - a good day doesn't predict the next one.
What helps: asking before assuming they can do something standing. Believing them when they say they need to sit. Not making them explain it in the moment.
What helps less: telling them to just drink more water like that's news. Saying they seemed fine a minute ago. Asking if it's just anxiety.
It's not anxiety. And the best thing you can give them is to let them sit down without making it a thing.
