Dysautonomia is the umbrella term for any disorder of the autonomic nervous system, the part of you that runs heart rate, blood pressure and digestion on its own. Postural orthostatic tachycardia syndrome (POTS) is one very common form, so everyone with POTS has dysautonomia, but not everyone with dysautonomia has POTS. (source: Cleveland Clinic)
If you’ve just been handed one of these words, or both, you probably have more questions than answers. That’s normal. These conditions can be confusing. You are not imagining this. Your symptoms make sense once we look at the nervous system.
What is dysautonomia, and how is POTS different?
Dysautonomia means the autonomic nervous system isn’t doing its job in balance. Cleveland Clinic describes it as a nervous system disorder that disrupts automatic body processes, such as your blood pressure and heart rate.
Think of the autonomic nervous system as the thermostat and the wiring in a house. You never flip a switch to make your heart beat or your stomach digest, because the system does it for you. When that wiring misfires, the symptoms can show up almost anywhere in the body.
POTS is one of the ways that misfiring shows up. The Dysautonomia Project calls POTS the most common autonomic nervous system disorder, and an under-recognized one that affects teens and adults. In plain terms, POTS is the form where your heart rate climbs too much when you stand up.
So the two words aren’t rivals. One is the family. The other is a member of it.
What types of dysautonomia are there?
More than most people expect. MedlinePlus lists what can go wrong when this system fails: blood pressure problems, heart problems, and trouble with breathing and swallowing.
POTS is the form people hear about most. Yours may lead with blood pressure, digestion or temperature control instead, and the type matters because care follows it. We cover the wider picture in our guide to dysautonomia symptoms and treatments.
How are dysautonomia and POTS similar?
They share the same underlying problem, which is a nervous system that isn’t regulating the body the way it should. That’s why the symptom lists overlap so heavily.
In both, you may feel lightheaded when you stand, get pounding or racing heartbeats, struggle with brain fog, and feel exhausted in a way sleep doesn’t fix. Digestion can slow down or go unpredictable. Heat, a hot shower, a long wait in line or a big meal can all push symptoms up.
Cleveland Clinic says more than 70 million people worldwide have some form of dysautonomia. You are far from the only one. If you want more on how the heart-rate piece works, we’ve written about why heart rates surge while standing in POTS.
How can you tell dysautonomia and POTS apart?
You can’t reliably tell them apart from symptoms alone, and I’d be wary of anyone who says you can. The difference comes from what a clinician measures and how your body behaves over time.
POTS is defined by a heart-rate response to standing, so a clinician looks at how your heart rate and blood pressure change as you move from lying down to upright. For dysautonomia more broadly, the testing is matched to the person. The Stanford Autonomic Disorders Program describes individualized autonomic testing maneuvers used to understand each patient’s disorder. Other forms may show a blood-pressure drop, trouble with sweating, or problems in digestion and the bladder instead of, or alongside, the racing heart.
Here is how the two compare at a glance.
| Dysautonomia | POTS | |
|---|---|---|
| What it is | An umbrella term for autonomic nervous system disorders | One specific form under that umbrella |
| Main signal | Varies by type, from blood pressure to digestion to temperature control | Heart rate that rises too much on standing |
| How it’s found | Autonomic testing matched to the affected body system | Heart rate and blood pressure tracked from lying to standing |
A person can have POTS and also have symptoms outside the heart-rate pattern, and then both words are accurate.
One caution. Wikipedia’s summary of the literature notes that anxiety can physically produce symptoms that resemble autonomic dysfunction. That is exactly why a careful workup matters, and why being told it’s anxiety doesn’t close the question until the testing is done.
What does day-to-day life look like with dysautonomia or POTS?
It looks like planning your day around a body that won’t promise how it will feel. Many people describe good hours and bad hours, and flare-ups that arrive without a clear trigger.
Standing in the kitchen to cook can leave you gripping the counter. A shower can mean sitting down halfway through. You might need to rest after a short walk, and then lose the whole next day to the cost of it. Brain fog can make you lose a word mid-sentence, which is frightening if you used to be sharp.
There’s an emotional layer too. You look fine on the outside, so people assume you are. Cancelling plans again can feel like failing, and it isn’t. It’s a body working hard to regulate itself, and a body that is working can be supported.
Some symptoms need urgent care. Cleveland Clinic’s advice is plain: call 911 or your local emergency number when in doubt.
Can dysautonomia and POTS show up with other conditions?
Often. Dysautonomia travels with other diagnoses, which can make the picture hard to read.
MedlinePlus says autonomic nervous system disorders can occur alone or as the result of another disease, such as Parkinson’s disease, alcoholism and diabetes. Researchers are also looking closely at the link with Long COVID, and the Stanford Autonomic Disorders Program says it has launched a study to investigate clinical characteristics of post-COVID POTS cases.
In my own clinical thinking, these overlaps matter because they often point to a nervous system that is struggling as a whole. Patients can have POTS with EDS, or dysautonomia with Long COVID, or amplified pain on top of both. That doesn’t mean every patient has every condition. It means a single label rarely tells the whole story, so we look at the whole person and not just one diagnosis. If Long COVID is part of your picture, our piece on fatigue and cognitive symptoms may help.
Who do dysautonomia and POTS typically affect?
Dysautonomia can affect almost anyone, but the pattern differs by type. The Dysautonomia Project describes POTS as affecting teens and adults, so it isn’t a condition only of older age.
Cleveland Clinic notes that the average time of onset for dysautonomia overall is between the ages of 50 and 60. That figure covers the whole umbrella, including forms that come with other diseases, so it says little about what a younger person with POTS should expect.
I can’t give you clinic statistics here. We haven’t published a measured breakdown of the patients we see by age or sex, and I won’t guess at one. What I can say is that people arrive after years of fragmented care, often having seen several specialists who each looked at one piece. That story comes up again and again.
What do we see in clinic?
The Spero Clinic works with patients who have dysautonomia and POTS. Many arrive after years of care spread across different providers.
We treat the nervous system, not just the symptom. A racing heart on standing is what you feel, and the nervous system regulating it is where we look. You can read how we handle dysautonomia at the clinic. We don’t promise a result, and individual outcomes vary. We do take time to listen to the full story first.
We’re also honest about who this isn’t for. It is an in-person program in Fayetteville, Arkansas, and it asks a serious commitment of time, travel and cost. It doesn’t replace medical evaluation or emergency care, and if you haven’t had a proper workup, that comes first.
Common mistakes people make with these diagnoses
People often get stuck choosing between the two words, as if they were separate problems. Ask your doctor which pattern your testing showed, and what else might be going on alongside it.
Another trap is accepting an anxiety label before any testing has been done. Anxiety can be part of the picture, but the physical causes deserve a proper check first.
Pushing through a flare to prove you can is a third. Overdoing a good day often costs you the days after, so it helps to track what you did and how you felt afterward, and a symptom diary makes your next appointment far more useful.
Finally, many people try to manage all of this alone. Explaining these conditions is tiring, and the people who support you do better when they understand what your body is doing.
FAQ
How do I know if I have dysautonomia?
You can’t know from symptoms alone. Lightheadedness on standing, a racing heart, fatigue, brain fog and digestive trouble are common clues. A clinician confirms it with autonomic testing. Bring a symptom diary to that visit.
What does a dysautonomia flare feel like?
People describe a sudden worsening of what they already feel. That may be dizziness, a pounding heart, deep exhaustion, nausea or fog. Heat, standing too long, big meals and poor sleep are common triggers, though some flares arrive with no clear cause.
What is the most effective treatment for dysautonomia?
There isn’t one answer, because dysautonomia has many forms and causes. Care depends on your type and any condition behind it. Some autonomic disorders improve when an underlying disease is treated, according to MedlinePlus. Talk with your clinician about a plan built around your testing.
Is dysautonomia the same as POTS?
Not quite. Dysautonomia is the category, and POTS is one condition inside it. You can have POTS and other autonomic symptoms too, which is why your test results tell you more than the label does.
