Functional Medicine for
POTS & Dysautonomia
These are not random conditions. They are signs of a nervous system that has lost its ability to adapt, regulate, and recover.
Living with POTS or dysautonomia can feel confusing, frightening, and deeply isolating. You may look “healthy” on the outside while dealing with dizziness, rapid heart rate, fatigue, anxiety, brain fog, exercise intolerance, or a sense that your body simply can’t regulate itself. Many patients are told it’s anxiety, dehydration, or something they just need to learn to live with.
At F8 Wellness, we see POTS and dysautonomia differently. These are not simply heart problems. Functional medicine looks at why this breakdown occurred and what systems are contributing to it.
What Is POTS and Dysautonomia?
POTS (Postural Orthostatic Tachycardia Syndrome) is a form of dysautonomia — a broad term used to describe dysfunction of the autonomic nervous system. This is the part of the nervous system responsible for automatic functions such as heart rate, blood pressure, digestion, temperature regulation, hormone signaling, and stress response.
In a healthy system, standing up triggers a coordinated response: blood vessels constrict, heart rate adjusts slightly, and blood flow to the brain is maintained. In POTS, this coordination breaks down. Heart rate spikes excessively, blood pressure may drop or fluctuate, and the brain experiences reduced oxygen delivery.
The Autonomic System Controls
Dysautonomia can exist with or without a formal POTS diagnosis and often overlaps with autoimmune disease, chronic fatigue, mast cell activation, thyroid dysfunction, and long COVID.
Common Symptoms Often Overlooked
Many POTS patients are dismissed because standard cardiac testing appears “normal.” Yet symptoms persist and often worsen over time.
Rapid Heart Rate
Dizziness
Exercise Intolerance
Shortness of Breath
Brain Fog
Chronic Fatigue
Panic Sensations
Temp Intolerance
Digestive Issues
Sleep Disturbance
These symptoms are frequently misattributed to anxiety, deconditioning, or stress alone, without addressing the underlying physiological drivers.
The Nervous System: The Missing Piece
At the core of POTS and dysautonomia is nervous system imbalance — specifically a system stuck in a chronic fight-or-flight state. The sympathetic nervous system becomes overactive, while the parasympathetic (rest-and-repair) system fails to engage appropriately.
Over time, the body loses resilience. Even minor stressors — standing, heat, emotional stress, or light exercise — can provoke exaggerated symptoms.
This Imbalance Disrupts
- Heart rate variability
- Blood vessel tone
- Adrenal signaling
- Immune regulation
- Inflammatory control
- Energy production
What’s Driving the Dysregulation
Adrenal Dysfunction and Stress Hormone Chaos
The adrenal glands play a critical role in regulating blood pressure, blood sugar, inflammation, and stress adaptation. In many POTS patients, adrenal signaling becomes dysfunctional due to chronic stress, illness, infection, or trauma.
At F8, we assess adrenal function functionally — not just whether cortisol exists, but whether it is being released at the right time, in the right amount, and in coordination with the nervous system.
This May Look Like
- Cortisol levels that are “normal” but poorly timed
- Excess adrenaline and norepinephrine output
- Blood sugar instability triggering flares
- Poor stress tolerance and delayed recovery
Inflammation, Autoimmunity, and Immune Triggers
A growing body of research shows strong links between dysautonomia and immune dysfunction. Inflammation can interfere with nerve signaling, blood vessel responsiveness, and mitochondrial energy production.
Rather than asking “Do you have POTS?” functional medicine asks “What is driving the inflammation that disrupted your nervous system regulation in the first place?”
Common Contributors
- Autoimmune activation
- Post-viral immune dysregulation
- Mast cell activation
- Gut permeability and microbiome imbalance
- Chronic inflammatory load
POTS and Long COVID
Since the COVID-19 pandemic, we have seen a significant rise in patients with POTS-like symptoms following viral infection. Long COVID frequently presents as a form of acquired dysautonomia.
For many long COVID patients, traditional testing offers little clarity. Functional medicine provides a framework for understanding how infection creates downstream nervous system dysfunction — and how to support recovery.
Viral Illness Can
- Trigger immune overactivation
- Disrupt autonomic nerve signaling
- Deplete mitochondrial energy reserves
- Alter adrenal hormone output
- Increase systemic inflammation
Why Conventional Care Often Falls Short
Conventional treatment for POTS often focuses on symptom management: increased fluids, salt, compression garments, beta blockers, or stimulants. While these may provide temporary relief, they rarely address the underlying drivers.
- Nervous system stress left unaddressed
- Immune imbalance not investigated
- Inflammation and metabolic instability ignored
- Adrenal dysfunction overlooked
This is why many patients feel stuck managing symptoms rather than improving function.
The F8 Functional Medicine Approach
We evaluate how multiple systems interact rather than isolating the heart or blood pressure alone. We look for patterns — not isolated abnormalities — to understand why your body lost its ability to self-regulate.
- Comprehensive blood work beyond standard panels
- Functional adrenal and metabolic assessment
- Immune and inflammatory markers
- Thyroid and hormone signaling evaluation
- Gut health and nutrient status
- Nervous system and brain-based evaluation
Rebuilding Regulation, Not Just Managing Symptoms
The goal of care is not simply to tolerate symptoms but to restore adaptability. This process takes precision, patience, and a personalized plan — but improvement is possible when the root causes are addressed.
Reducing Inflammatory Load
Calming the immune triggers that interfere with nerve signaling
Stabilizing Blood Sugar
Supporting energy production and reducing symptom flares
Adrenal & Hormone Support
Restoring proper cortisol timing and stress hormone communication
Calming the Nervous System
Shifting the body out of chronic fight-or-flight
Oxygen & Nutrient Delivery
Improving circulation and cellular nourishment to tissues
Restoring Balance
Teaching the body how to return to self-regulation
You Are Not Broken — Your System Is Overloaded
POTS and dysautonomia are not signs of weakness or anxiety. They are signals that your body has been under prolonged stress and lost its regulatory capacity. At F8, we believe symptoms are messages. When we listen carefully and investigate deeply, we can help the body move back toward stability.
Restore Nervous System Balance
If you’ve been told your tests are normal but your life feels anything but, it may be time for a deeper evaluation.
At F8 Wellness, we help uncover the root causes of POTS and dysautonomia and guide your body back toward self-regulation.
