POTS & Dysautonomia Provider in St. Augustine, FL
If you are living with Postural Orthostatic Tachycardia Syndrome (POTS) or broader Dysautonomia, the simple act of standing up can feel like a grueling physical challenge. You might experience a sudden, racing heart rate, a wave of lightheadedness, cold sweat, or a feeling that all the blood is instantly draining from your brain.
To make matters worse, this cardiovascular chaos is almost always paired with unremitting brain fog, profound fatigue, and debilitating digestive issues.
Because standard cardiac workups like EKGs and echocardiograms usually come back “perfectly normal,” conventional medicine frequently misdiagnoses POTS as simple generalized anxiety, panic disorders, or deconditioning. You are told to eat more salt, wear compression socks, and take beta-blockers to force your heart rate down.
At Foundational Health, we don’t look at POTS as a structural heart condition. We look at it for what it truly is: a profound coordination failure in the Autonomic Nervous System (ANS). We provide comprehensive, investigative care to patients across St. Augustine and Northeast Florida, digging deep to find the biological and environmental overloads that have hijacked your brain’s regulatory software.
Dr. James Roman has 25 years of clinical experience.
What is POTS? (Postural Orthostatic Tachycardia Syndrome)
To truly understand Postural Orthostatic Tachycardia Syndrome (POTS), we have to look past your heart and focus entirely on the physics of your nervous system. POTS is not a structural heart disease; your heart is actually a perfectly healthy muscle responding to a massive communication failure upstairs.
POTS is a primary manifestation of Dysautonomia—a condition where the Autonomic Nervous System (ANS) loses its ability to automatically regulate the basic, unconscious functions of your body.
In a healthy individual, shifting from a sitting or lying position to a standing position triggers an instantaneous, highly coordinated reflex. The moment you stand, gravity naturally pulls your blood downward into your abdomen and lower extremities. To ensure your brain isn’t starved of oxygen, your brainstem immediately tells your blood vessels to constrict (tighten) and slightly increases your heart rate, effortlessly maintaining stable blood pressure and perfect circulation.
When you are dealing with POTS, that automatic software loop is completely broken.
When you stand up, your blood vessels fail to tighten efficiently, causing blood to pool heavily in your lower body. Your brainstem suddenly registers an acute oxygen crisis in your upper torso and head. To keep you from losing consciousness, your lower survival brain slams down on the emergency sympathetic “gas pedal”—flooding your system with adrenaline and forcing your heart to rapidly spike its rate by 30 beats per minute or more just to push blood upward against gravity.
This is not an emotional panic attack or “deconditioning.” It is a physical, mechanical emergency. Your nervous system is locked in an architectural survival loop, leaving you trapped in a state of high-frequency sympathetic dominance that drains your cellular energy and leaves you feeling completely spent.
The Foundational Health Approach To POTS Recovery
The symptoms of POTS are frequently dismissed as psychological stress because standard heart and blood tests often appear normal. Our team bridges the gap between cardiology and functional medicine, offering a path to stability that addresses both the cellular environment and the brain’s control center.
Root Cause Identification via Functional Diagnostics
We test for the
Targeted Neurological and Vagus Nerve Toning
We utilize specific exercises an
Brain-Based System Retraining
We utilize core therapies like Limbic Retraining and Neuro Emotional Technique to desensitize the chronic threat response center of the brain,
Neuro-Structural Technique
We address physical trauma and structural issues—including airway stabilization—to ensure your brain receives its most basic fuel (oxygen), preventing the primal “suffocation response” that can trigger POTS flares.
Frequent Asked Questions
What is the connection between POTS and Mast Cell Activation Syndrome (MCAS)?
Hyper-reactive mast cells constantly flood your bloodstream with inflammatory chemicals like histamine, which force your blood vessels to suddenly relax and widen. This massive chemical dilation drastically worsens lower-body blood pooling, forcing your heart to beat at a frantic pace to keep your brain oxygenated.
Can hidden mold illness or mycotoxins actually cause POTS?
Yes, inhaled mycotoxins from humid coastal environments easily cross the blood-brain barrier and cause severe, localized inflammation inside your brainstem. This physical inflammation directly short-circuits your nervous system’s automatic software, completely breaking the reflex that regulates your heart rate and blood pressure when you stand up.
Why does my POTS make me feel so anxious if it's a physical condition?
When blood pools in your lower body, your brainstem enters a physical survival panic due to a sudden drop in oxygen, triggering a massive, automatic dump of adrenaline. Your brain then interprets this intense, physical adrenaline storm as an emotional feeling of anxiety or impending doom, meaning the panic is an inside-out physiological event rather than a psychological defect.
Can environmental toxins like mold or heavy metals really cause panic attacks?
Yes. Certain environmental toxins are neuro-irritants. Mycotoxins from water-damaged buildings or heavy metal accumulation can cross the blood-brain barrier and interfere with your neurotransmitters. This creates a state of “Biochemical Anxiety,” where your brain is reacting to a physical poison in its hardware rather than an emotional stressor in your life. We use advanced functional testing to identify if these “silent fillers” are what’s causing your bucket to overflow.
Can I completely recover from POTS, or is this something I just have to manage forever?
While conventional medicine focuses only on managing symptoms with beta-blockers, POTS is actually a reversible software error in the nervous system. By systematically clearing hidden environmental toxins and utilizing targeted neuroplasticity training, your brain can successfully rewire its pathways and restore normal autonomic balance.

“Your racing heart and sudden dizziness are not an emotional panic attack, and they aren’t ‘in your head.’ It is a physical, mechanical gravity crisis triggered by an overloaded nervous system that has simply forgotten what it feels like to be safe.”
