Dysautonomia Specialist and Treatment
You have a cardiology file, a gastroenterology file and a neurology file. Each specialist found their part of you unremarkable. Nobody has explained why all of it started at once. If you are searching for a dysautonomia doctor near you, it is usually because someone finally said the word and then handed you nothing else.
There is a version of this story where the symptoms are unrelated and you are unlucky. There is another where one system controlling all of those organs is malfunctioning, and no one has tested it.
The second version is far more common than the first.
What is Dysautonomia?
Dysautonomia is a group of disorders where the autonomic nervous system malfunctions. You will also see it called autonomic neuropathy.
The autonomic nervous system runs your body without your involvement. Heart rate, blood pressure, digestion, temperature, bladder, sleep. You have never once had to remember to keep your heart beating.
It has two branches. The sympathetic branch handles threat, the fight-or-flight response. The parasympathetic branch handles recovery, rest and digestion. Neither is the bad, you need both.
They work back and forth. When one side rises the other falls, and health lives in the movement between them.
In dysautonomia the movement becomes inconsistent. In the post-viral form it tends to lock with the sympathetic side elevated and the parasympathetic side suppressed, so the body sits in a state of permanent low-grade emergency.
Because a body convinced it is in danger will struggle to drop into deep sleep, will not prioritize tissue repair, and keeps producing inflammation.
Recovery needs the parasympathetic side to come back up.
While the dynamic movement remains stuck, the body keeps putting “threat” ahead of repair, at night.
Why your symptoms look unrelated
The autonomic nervous system controls many part of the body so its failure can show up everywhere at once. The symptom list can include several different issues.
| System | What it looks like |
|---|---|
| Cardiovascular | Dizziness or lightheadedness on standing, fainting, rapid heart rate, chest pain |
| Digestive | Nausea, bloating, abdominal pain, constipation, diarrhea, difficulty swallowing |
| Neurological | Headaches and migraines, brain fog, extreme fatigue, hoarseness, coat hanger pain across head, neck and shoulders, tinnitus, tingling and numbness, internal vibrations |
| Breathing | Shortness of breath on minimal exertion |
| Temperature | Sweating too much or too little, running persistently hot or cold, cold hands and feet |
| Bladder | Frequent urination, difficulty urinating, incomplete emptying |
| Sleep | Insomnia, and unrestorative sleep even after seven or eight hours |
| Musculoskeletal | Muscle weakness, muscle pain, joint pain |
| Psychological | Anxiety, low mood, derealization and depersonalization |
Coat hanger pain, tinnitus and internal vibrations deserve a mention of their own. They are classic dysautonomia symptoms and widely under-recognized. The people reporting them are often believed, the least.
Symptoms also vary day to day in the same person, and that variability is itself diagnostic, because it reflects real-time fluctuation in autonomic balance. It also makes the condition hard to prove in a fifteen-minute appointment, and it is a common reason people get told the problem is stress.
What type of doctor treats dysautonomia?
No one specialty clinic currently owns this condition. The gap is exactly why so many people spend years being referred to other practitioners.
Autonomic neurology is the closest formal match. Autonomic specialists work with this system directly. The constraint is supply, since these clinics cluster at a handful of academic centers with long waits.
Cardiology handles the cardiovascular presentation and is essential for excluding structural disease, though a normal heart does not rule out a nervous system failing to regulate it.
Gastroenterology, urology and sleep medicine each see one organ’s version of the same problem. Each can help with that organ. Few of them are looking at the system as a whole.
Primary care is well placed to notice a pattern across systems and is rarely given the appointment length to do it.
My own background is anesthesiology and interventional pain medicine, and I came to autonomic work by spending years using stellate ganglion blocks on the sympathetic nervous system for chronic pain and PTSD. When patients arrived after COVID infections unable to smell or taste, and their smell returned almost immediately after a block, the first indication something broader was happening at the level of the autonomic system.
What you are looking for is a clinician willing to treat the autonomic nervous system as one system, look for the cause instead of stopping at the diagnosis, and test rather than infer.
How to tell in one appointment
If you have already sat through appointments where nobody looked past one organ, two questions will usually tell you whether this clinic is different.
Ask what testing looks at the autonomic system itself, not at individual organs one at a time. Tilt table, heart rate variability, COMPASS 31 and autonomic function testing are the ones built for the question.
Then ask whether the workup will look for a secondary cause. A diagnosis of dysautonomia without a search for what produced it is a label, and a label does not tell you what to treat.
The forms dysautonomia takes
Dysautonomia is an umbrella. Because the forms underneath it are treated differently, working out which one you have can change what happens at the next appointment.
POTS is the most common form and the one most people arrive already suspecting. It is defined by an excessive heart rate rise, typically 30 beats per minute or more, on standing. Worth being precise, because the terms get used interchangeably and they are not the same. POTS is one form of dysautonomia, and many people with dysautonomia do not have POTS. If your dominant problem is your heart rate on standing, the detail lives on POTS specialist and treatment.
Orthostatic hypotension is the opposite pattern. Blood pressure drops on standing rather than heart rate climbing to compensate, defined as a fall of at least 20 mmHg systolic or 10 mmHg diastolic within three minutes of standing.
Vasovagal syncope is a reflex in which the vagus nerve becomes suddenly overactive, dropping heart rate and blood pressure together and causing a brief loss of consciousness. Needles, the sight of blood, stress, exhaustion and prolonged standing in heat are the usual triggers. Fainting at a blood draw is a specific autonomic reflex.
Primary dysautonomias are genetic rather than acquired, and include Ehlers-Danlos Syndrome, Familial Dysautonomia and hereditary sensory and autonomic neuropathy.
If you feel a faint coming on, warning signs usually arrive before the faint does, such as a wave of warmth, sweating, pale skin, nausea and a slowing pulse. Squeeze a ball hard, grip your hands together and pull them apart against each other, or cross your legs and tense the muscles. Each raises blood pressure and can stop an episode before it finishes. Get yourself low before you fall rather than trying to stay upright.
What causes it, and what matters most
If only one distinction from this page is worth carrying into an appointment, it is primary versus secondary.
Primary dysautonomia is genetic. Secondary dysautonomia is caused by something else, and secondary causes are not necessarily permanent.
Secondary causes span roughly fifteen categories. The most common:
- Autoimmune disease, including lupus, rheumatoid arthritis, Sjögren’s, multiple sclerosis, Guillain-Barré and autoimmune autonomic ganglionopathy
- Infections, including Epstein-Barr, Lyme disease and hepatitis C
- Post-viral syndromes, including Long COVID
- Diabetes, through diabetic autonomic neuropathy
- Thyroid and adrenal disorders, including hypothyroidism, hyperthyroidism and Addison’s disease
- Nutritional deficiency, particularly vitamin B12 and thiamine, both correctable
- Medications, including certain antidepressants
- Trauma, including traumatic brain injury and spinal cord injury
- Chronic conditions including ME/CFS and fibromyalgia
- Peripheral neuropathies, including small fiber neuropathy
Two of these get missed routinely.
B12 and thiamine deficiency can each produce autonomic dysfunction and are straightforward to correct once someone thinks to check.
Certain antidepressants, particularly TCAs and SNRIs, increase sympathetic activity and reduce vagal tone. If your autonomic symptoms worsened after a medication change, that timing is worth raising with your prescriber rather than assuming coincidence.
There is also evidence COVID-19 damages or thickens the vagus nerve, a direct route from infection to secondary dysautonomia.
Why standard testing says you are fine
The autonomic nervous system is not directly measurable on a standard blood panel or on routine imaging.
This is the mechanical reason so many people are told their tests are normal while they are visibly unwell. Many of those tests are answering a question about structure when the problem is regulation.
Testing built for the question includes tilt table testing for the orthostatic response, heart rate variability, the COMPASS 31 autonomic symptom assessment, and formal autonomic function testing. Alongside those, the secondary-cause workup matters: thyroid panel, B12 and thiamine, autoimmune markers, and a review of current medications.
One more thing worth naming. Pre-existing autonomic damage appears to work in both directions, as a risk factor for developing Long COVID and also as a result of it. Many people carried quiet autonomic vulnerability for years, from thyroid disease, autoimmune conditions or prolonged stress, and an infection made it visible. If you were the one in your household who did not recover, this may be part of why.
That reframes what recovery involves.
You may not be recovering from a single infection so much as repairing an autonomic system with less reserve before the infection arrived. It is a less tidy story, and it explains why an approach aimed only at the virus tends to disappoint.
What to bring to your appointment
Two weeks of notes will do more for a first visit than any account of how you have been feeling.
Keep a short symptom log by system: cardiovascular, digestive, neurological, temperature, sleep. One line each per day is enough.
Note what makes days worse and what makes them better. Heat, prolonged standing, stress, dehydration and menstrual timing are the usual candidates.
A medication and supplement list with start dates is worth pulling together, antidepressants especially, alongside a note on whether symptoms changed after any of them began.
Bring recent labs if you have them, especially thyroid function, B12 and any autoimmune markers already run. It saves repeating work and shows quickly what has not been checked.
If you want to bring position-change measurements as well, ask your clinician how to take them safely first. Standing tests are designed to provoke the symptom, so they are not something to attempt alone. What each test involves is covered on how POTS is diagnosed.
Treatment
The aim is to restore movement, not to chase each organ separately.
Treat the secondary cause where there is one. Correcting a B12 deficiency, addressing thyroid dysfunction, or reviewing a medication known to suppress vagal tone can change the baseline before anything else is attempted. This step is routinely skipped.
Vagus nerve stimulation activates the parasympathetic side directly, and can be run as a daily protocol at home.
Stellate ganglion block quiets the overactive sympathetic side. Local anesthetic is placed around the stellate ganglion, a cluster of sympathetic nerves in the neck. My post-viral protocol injects at two levels, C6 and C4, uses live ultrasound guidance throughout, uses an echogenic short-bevel needle, and adds no steroid. It is performed one side at a time.
Expected temporary effects on the injected side resolve within hours: a drooping eyelid, a smaller pupil and no sweating on that side (Horner’s syndrome), hoarseness, facial flushing, nasal congestion.
Response varies. It can be durable, or it may fade depending on how fixed the sympathetic overdrive has become, and stress or a new illness can bring symptoms back. If you are considering this procedure anywhere, ask whether live ultrasound guidance is used throughout the injection. The stellate ganglion sits near the carotid artery, the vertebral artery and the spine.
Symptom-level support still matters while the underlying work happens. Fluid and salt for volume, compression garments, and pacing matched to post-exertional malaise where it is present. See PEM and pacing.
(Discuss any new treatment or medication with your doctor before starting.)
Treating the autonomic dysfunction itself tends to move several symptoms together, because they were expressions of one system rather than separate conditions.
Dysautonomia and Long COVID
Dysautonomia is one of six mechanisms I work through in post-viral illness, alongside mitochondrial dysfunction, endothelial damage, gut dysbiosis, mast cell activation and hormone imbalance.
It is common and because it drives the widest spread of symptoms. It is rarely the only one present.
The route from infection to autonomic failure is not hypothetical. There is evidence the virus damages or thickens the vagus nerve itself, the primary route between the brain and the organs, carrying the parasympathetic signals regulating heart rate, digestion, breathing and inflammation control. Damage there is part of why Long COVID symptoms appear across so many systems at once instead of in one.
Post-viral dysautonomia is also secondary by definition. It was acquired, so it is not automatically permanent.
When the same fatigue can come from autonomic dysfunction, from mitochondrial failure, from impaired circulation or from hormone disruption, treatment only works once it is aimed at the right outcome. That is why the evaluation identifies which mechanisms are active for you instead of assuming.
Traveling for treatment
Patients travel to the Plano clinic from outside Texas. If you are considering this recovery option, getting to treatment covers how we help with flights, accommodation and transport.
Getting evaluated
The evaluation starts with your history, moves through testing aimed at the autonomic system itself, not around it, and works toward identifying the cause rather than confirming the label. We see patients in Plano and across the Dallas-Fort Worth area, and patients travel from outside the US.

Frequently asked questions
What kind of doctor treats dysautonomia?
Autonomic neurology is the closest formal specialty, though access is limited and waits at academic centers are long. Cardiology, gastroenterology, urology and sleep medicine each address one organ’s presentation of the same problem. What matters is finding a clinician with a whole-system view, who investigates the underlying cause and tests the system directly instead of inferring from symptoms.
Do neurologists treat dysautonomia?
Yes. Autonomic neurology is the subspecialty closest to dysautonomia, and it is where formal autonomic function testing usually sits. The limitation is access rather than capability, since autonomic clinics cluster at a small number of academic centers. A general neurologist may or may not work with autonomic disorders specifically, so it is worth asking before booking.
What is dysautonomia mistaken for?
Dysautonomia is most often mistaken for anxiety, because the symptoms are diffuse, they fluctuate day to day, and standard tests come back normal. It is also mistaken for a collection of separate conditions, with each specialist treating one organ’s version of it. Deconditioning, chronic fatigue and irritable bowel syndrome are common partial labels describing a piece of the picture without naming the system underneath.
Why are my tests normal if something is wrong?
The autonomic nervous system is not directly measured by standard blood panels or routine imaging. Those tests assess structure. Dysautonomia is a problem of regulation, so it needs tests built for that, such as tilt table testing, heart rate variability, COMPASS 31 and autonomic function testing.
Is dysautonomia the same as POTS?
No. Dysautonomia is the umbrella term for autonomic nervous system dysfunction. POTS is one specific form of it, defined by an excessive heart rate rise on standing, and many people with dysautonomia never meet POTS criteria.
Can dysautonomia be cured?
Primary dysautonomia is genetic and is managed rather than reversed. Secondary dysautonomia, meaning the acquired kind, is not necessarily permanent, and treating the underlying cause can improve autonomic function. Outcomes vary between people and no responsible clinician promises resolution.
Can Long COVID cause dysautonomia?
Yes. Post-viral syndromes are a recognized secondary cause of dysautonomia, and there is evidence COVID-19 damages or thickens the vagus nerve. Pre-existing autonomic damage also appears to work in both directions, as a risk factor for developing Long COVID and as a result of it.
What tests should I ask for?
Tilt table testing, heart rate variability, COMPASS 31 and autonomic function testing assess the system directly. A secondary-cause workup should include thyroid function, vitamin B12 and thiamine, autoimmune markers and a review of current medications.
