Postural Orthostatic Tachycardia Syndrome (POTS) in Iowa: Why Upper Cervical Care Belongs in Your Treatment Plan

There is a particular kind of medical gaslighting that POTS patients know well. You stand up and your heart rate spikes to 130. The room tilts. Your vision grays at the edges. Your legs feel like they're filled with sand. You sit back down and wait for it to pass, wondering if this is going to be your life now — navigating the world from one chair to the next, planning every movement around whether your body will cooperate this time.

You bring these symptoms to your doctor. They run tests. Some come back abnormal, enough to eventually produce a diagnosis — postural orthostatic tachycardia syndrome, or POTS. Others come back frustratingly normal. Either way, what you are offered is a management protocol: salt, fluids, compression garments, beta blockers, fludrocortisone. Possibly a referral to cardiology or neurology. The message, spoken or unspoken, is that POTS is something to be managed, not resolved — a dysfunction of the autonomic nervous system that medicine can compensate for but cannot get to the root of.

For many POTS patients, that message is accepted out of exhaustion. But it is not the complete picture. And for a meaningful subset of POTS patients — particularly those with onset following a physical trauma, those whose POTS coexists with other neurological symptoms, and those who have never achieved satisfactory control despite consistent medical management — there is a structural piece that conventional POTS care does not address.

That piece sits at the top of the cervical spine, in the position of the atlas (C1) — and it may be the most important variable in the entire picture that no one has ever examined.

What POTS Is — and What It Isn't
Postural orthostatic tachycardia syndrome is defined by an abnormal increase in heart rate upon moving from lying or sitting to standing — typically 30 beats per minute or more within ten minutes of standing, in the absence of orthostatic hypotension. This tachycardia is accompanied by a constellation of symptoms that can include lightheadedness, presyncope (near-fainting), palpitations, fatigue, brain fog, headaches, nausea, exercise intolerance, temperature dysregulation, and in some cases actual syncope.

POTS is classified as a form of dysautonomia — a disorder of the autonomic nervous system. The autonomic nervous system governs all of the body's involuntary regulatory functions: heart rate, blood pressure, vascular tone, respiratory rate, digestion, temperature regulation, and the body's response to positional changes. In POTS, this system fails to make the appropriate cardiovascular adjustments when the body moves from horizontal to vertical — it cannot efficiently redirect blood flow from the extremities back to the thorax and brain, triggering the compensatory tachycardia that characterizes the condition.

What POTS is not is a cardiac condition. The heart itself is typically structurally normal in POTS. The dysfunction is in the autonomic regulation of cardiac function — a neurological failure, not a mechanical one. This distinction is critical, because it points directly toward the brainstem — the primary site of autonomic regulation — as the locus of dysfunction. And the brainstem is precisely where atlas misalignment has its most significant neurological impact.

The POTS Epidemic — and Why Iowa Patients Are Struggling
POTS is not rare. Estimates suggest that between one and three million Americans are affected, with the condition disproportionately striking women between the ages of 15 and 50. Since the COVID-19 pandemic, the number of POTS diagnoses has risen dramatically — post-COVID autonomic dysfunction has brought an entirely new wave of patients into the dysautonomia community, many of whom are young, previously healthy, and struggling to access care that understands their condition.

Iowa POTS patients face particular challenges. Specialized autonomic neurology is concentrated in major academic medical centers, and while the University of Iowa Hospitals and Clinics in Iowa City provides excellent general neurology and cardiology resources, the waiting times for specialized dysautonomia care can stretch for months. In the interim, patients are managing complex, debilitating symptoms with limited guidance and limited access to the kind of interdisciplinary care their condition demands.

What most Iowa POTS patients are not being offered — at UIHC, at local cardiology practices, or at general neurology offices — is upper cervical chiropractic evaluation. And yet the anatomical rationale for including it in a POTS treatment plan is direct, evidence-informed, and clinically compelling.

The Brainstem Is the Heart of POTS — and the Atlas Is Its Structural Guardian
The autonomic nervous system is regulated through a network of brainstem nuclei — clusters of neurons in the medulla oblongata and pons that continuously process cardiovascular, respiratory, and visceral information and generate the output signals that maintain homeostasis. The nucleus tractus solitarius receives cardiovascular afferent input. The rostral ventrolateral medulla drives sympathetic tone. The dorsal motor nucleus of the vagus and the nucleus ambiguus generate parasympathetic cardiac output through the vagus nerve.

In POTS, this brainstem regulatory network fails to coordinate appropriately with postural change. The vasoconstriction and heart rate adjustment that should occur within seconds of standing — mediated by brainstem cardiovascular centers — is delayed, insufficient, or dysregulated. The heart rate overshoots. Blood pools in the lower extremities. The brain is transiently underperfused. Symptoms follow.

The atlas (C1) surrounds the medulla oblongata — the very region where these autonomic regulatory centers live — more intimately than any other vertebral structure. When the atlas is in its optimal position, the medullary autonomic centers operate in an open, uncompromised mechanical environment. When the atlas is displaced — from trauma, postural loading, birth injury, or cumulative strain — it can create mechanical stress on the medullary tissue, alter the neurochemical environment through which the autonomic nuclei operate via changes in cerebrospinal fluid circulation, and reduce the vertebral artery blood flow that supplies the posterior brainstem.

The result is a brainstem whose autonomic regulatory function is mechanically impaired — in addition to whatever other pathological processes are driving the POTS diagnosis. The atlas displacement does not cause POTS de novo in every case. But it compounds the autonomic dysfunction that is already present, raising the symptom burden above what the underlying condition alone would produce and limiting the effectiveness of management strategies that are otherwise appropriate.

The Trauma Connection: Why So Many POTS Patients Have a Neck Story
One of the most striking patterns in the POTS community is the frequency with which patients report onset of their dysautonomia symptoms following a physical trauma — a car accident, a fall, a sports injury, a difficult delivery, a surgical procedure involving the neck. This pattern is too consistent to be coincidental, and it has not been adequately explained by the conventional POTS literature.

Atlas misalignment from physical trauma provides a direct structural explanation. A rear-end collision that displaces the atlas can initiate the brainstem mechanical stress and autonomic dysregulation that produces POTS symptoms — sometimes immediately, sometimes gradually over the following weeks and months as the nervous system's compensatory capacity is exhausted. The trauma is the event that shifts the atlas. The POTS is the neurological consequence of the brainstem operating in a mechanically compromised environment from that point forward.

For Iowa POTS patients who can identify a specific physical event that preceded or coincided with their symptom onset — even one that seemed minor, even one that occurred years before the formal POTS diagnosis — upper cervical evaluation is not just warranted. It is arguably the most important clinical step that has not yet been taken.

The Craniocervical Instability Connection
A subset of POTS patients — particularly those with connective tissue disorders such as Ehlers-Danlos syndrome (hEDS) and hypermobility spectrum disorder — have craniocervical instability (CCI): excessive laxity of the ligaments supporting the craniocervical junction that allows abnormal movement of the atlas relative to the skull and axis. CCI is increasingly recognized in the dysautonomia community as a significant contributor to POTS and related conditions, operating through exactly the mechanisms described above — brainstem compression, CSF flow disruption, and vagal dysfunction.

The same structural principles that make upper cervical evaluation essential for trauma-related POTS apply to CCI-related POTS. The difference is that in CCI patients, the instability requires a particularly gentle, low-force approach — one that stabilizes and supports rather than forcefully manipulating hypermobile tissue. The Advanced HIO Knee Chest technique, with its low-force, precisely calculated correction, is specifically appropriate for this population in a way that high-velocity cervical manipulation is not.

The Vagus Nerve: POTS' Most Important Underappreciated Factor
The vagus nerve is the primary parasympathetic pathway governing cardiac chronotropy — heart rate regulation. Adequate vagal tone is essential for the beat-to-beat modulation of heart rate that keeps the cardiovascular response to postural change appropriate. Low vagal tone — the parasympathetic system unable to adequately counterbalance sympathetic activation — is a consistent finding in POTS patients, and it is one of the primary reasons the heart rate overshoots on standing.

The vagus nerve originates in the medullary nuclei immediately adjacent to the atlas. Atlas misalignment that creates brainstem mechanical stress directly compromises vagal tone — reducing the parasympathetic cardiac modulation that POTS patients cannot afford to lose. This is why atlas correction can produce improvements in POTS symptoms that go beyond what the mechanical brainstem stress reduction alone would predict: restoring the structural environment for vagal function removes a layer of parasympathetic suppression that has been compounding the underlying autonomic dysfunction.

What Standard POTS Management Does — and What It Can't Reach
The standard POTS treatment protocol has genuine value. High sodium and fluid intake expands plasma volume, reducing the blood pooling that drives symptoms. Compression garments mechanically redirect venous return from the extremities. Beta blockers blunt the sympathetic tachycardia. Fludrocortisone and midodrine support blood pressure and vascular tone. Exercise rehabilitation — particularly recumbent and progressive upright exercise — rebuilds the cardiovascular conditioning that POTS disrupts.

These interventions compensate for the autonomic dysfunction. They do not address the structural brainstem environment in which the autonomic dysfunction is occurring. When a patient's atlas is displaced and their brainstem is under mechanical stress, every compensatory intervention is working against a structural headwind. The medications help, but their effect ceiling is lower than it would be if the brainstem's mechanical environment were optimal. The exercise rehabilitation is harder to tolerate and progresses more slowly.

Correcting the atlas does not replace these management strategies. It removes the structural constraint that is limiting their effectiveness — and for some patients, it reduces the symptomatic burden to a level where the management protocol becomes significantly more manageable.

What Upper Cervical Evaluation and Care Looks Like at Atlas Specific Chiropractic
At Atlas Specific Chiropractic in Hiawatha, Iowa, Dr. Isaac Reis evaluates POTS and dysautonomia patients with the same precision-based methodology applied to every complex neurological presentation — with particular attention to the autonomic dimension that makes these patients' care unique.

Comprehensive History Including Trauma Investigation and Symptom Pattern
‍The evaluation begins with a detailed history of the POTS presentation: when symptoms began, what precipitated onset, the current symptom pattern and severity, existing management strategies, and any prior physical trauma — however distant or seemingly minor. Dr. Reis specifically investigates the craniocervical junction's role in the autonomic picture and looks for the patterns — trauma history, concurrent neurological symptoms, hypermobility signs — that indicate a structural upper cervical component.

‍Upper Cervical Specific X-Rays
‍X-rays taken from precisely calibrated angles reveal the exact three-dimensional position of the atlas — its lateral displacement, rotation, and vertical tilt. For POTS patients, this imaging frequently reveals atlas displacement patterns that have never been identified in prior medical workup. The correction calculated from this imaging is customized to each patient's specific anatomy — there is no standardized POTS protocol, because no two atlas displacements are identical.

‍Tytron C5000 Paraspinal Infrared Thermography
‍The neurological heat asymmetry scan provides an objective map of where the nervous system is under the most mechanical stress. For POTS patients, the upper cervical thermography pattern reflects the brainstem autonomic burden that is compounding their dysautonomia — and it changes measurably as care progresses, providing objective evidence of nervous system recalibration independent of the day-to-day symptom variability that characterizes POTS.

‍The Advanced HIO Knee Chest (AHKC) Correction
‍The correction is a low-force, precisely calculated contact to the atlas — no twisting, no cracking, no high-velocity thrust. For POTS patients — many of whom have connective tissue hypermobility, heightened autonomic reactivity, and sensitivity to physical intervention — the low-force nature of the AHKC technique is specifically appropriate. The gentleness is not a compromise. It is the right tool for a population that needs structural correction without the autonomic stress of forceful manipulation.

What Iowa POTS Patients Typically Experience
The arc of improvement for POTS patients who address atlas misalignment varies considerably based on the duration and severity of their condition, the degree of atlas displacement, and how well their spine holds correction. But certain themes emerge consistently:

In the first weeks of care, many patients notice improvements in sleep quality, reduction in baseline neck tension, and a slight decrease in the frequency or severity of their worst symptom episodes. Over the following months, as the spine stabilizes and the brainstem's autonomic regulatory environment improves, the standing heart rate response often becomes less extreme, the postexertional symptom burden decreases, and the overall functional capacity for daily activity gradually expands.

For post-COVID POTS patients — a growing population in Iowa and across the country — the structural dimension of their autonomic dysfunction may be particularly significant, as COVID-19 is known to affect the brainstem and autonomic regulatory centers directly. Upper cervical correction that reduces the mechanical burden on already-stressed brainstem tissue may be a meaningful complementary intervention for this population.

Frequently Asked Questions
‍Can upper cervical chiropractic cure POTS?
No — upper cervical care does not cure POTS. It addresses a specific structural dimension — atlas misalignment and the brainstem mechanical stress it creates — that may be compounding the autonomic dysfunction driving POTS symptoms. For patients in whom this structural component is significant, correction of the atlas can meaningfully reduce symptom burden and improve the effectiveness of existing management strategies. It is best understood as a complementary structural intervention, not a standalone cure.

‍I have hEDS and POTS. Is upper cervical care safe for me?
Yes, with appropriate technique. The AHKC correction is specifically low-force and does not involve high-velocity manipulation — making it appropriate for patients with connective tissue hypermobility who cannot safely receive standard cervical manipulation. Dr. Reis is experienced with hypermobile patients and tailors the correction approach accordingly. Each case is evaluated individually based on the degree of instability and the patient's overall clinical picture.

‍My POTS started after a car accident. Is there a connection?
This is one of the most compelling presentations for upper cervical evaluation. Physical trauma to the head and neck — including whiplash from car accidents — can displace the atlas and initiate the brainstem autonomic dysregulation that produces POTS symptoms. If your POTS began or significantly worsened following a neck or head injury, atlas evaluation should be a high priority in your management plan.

‍I'm already on medications for POTS. Can I still pursue upper cervical care?
Yes. Upper cervical care does not interfere with POTS medications. Many patients pursue both simultaneously. As structural correction reduces the autonomic burden, some patients find in consultation with their prescribing physician that medication adjustments become possible over time — but any changes to medication should be made under medical supervision.

‍How long before I notice improvements in my POTS symptoms?
This varies considerably. Some patients notice early shifts — improved sleep, reduced baseline neck tension, slightly better standing tolerance — within the first four to six weeks of consistent care. Others require two to three months of consistent care before meaningful autonomic changes become apparent. POTS is a complex condition and recovery timelines reflect that complexity. Objective thermography data tracks the nervous system's response independently of day-to-day symptom variability.

‍Do I need a referral from my cardiologist or neurologist?
No referral is required. You can schedule directly by calling 319-343-8540 or booking online at iowaatlasspecific.com. Dr. Reis welcomes coordination with existing POTS care teams and is happy to share evaluation findings with your managing physicians.
