For many people living with Postural Orthostatic Tachycardia Syndrome (POTS), every day can feel unpredictable. One morning you wake up feeling relatively normal. The next, simply standing up leaves you dizzy, lightheaded, and exhausted. Some days you can attend school, work, or social events. Other days, taking a shower or walking through the grocery store feels like running a marathon.
For teenagers especially, POTS can be incredibly frustrating. Many were once active in sports, involved in school activities, and constantly on the go. Then seemingly out of nowhere, their energy disappears. Concentration becomes difficult. Heart palpitations become common. Standing up causes dizziness. Daily activities that once felt simple suddenly become overwhelming.
Unfortunately, POTS is often misunderstood. Many patients spend months or even years searching for answers. Some are told it's anxiety. Others are prescribed medications that help manage symptoms but never fully explain why the symptoms developed in the first place.
The good news is that researchers are learning more about POTS every year. While there is still much to discover, one thing is becoming increasingly clear: POTS is not simply a heart rate problem. It is often a nervous system problem. To understand why, we first need to understand what POTS actually is.
What Is POTS?
Postural Orthostatic Tachycardia Syndrome, commonly called POTS, is a form of dysautonomia. Dysautonomia refers to dysfunction within the Autonomic Nervous System, the system responsible for regulating automatic functions such as heart rate, blood pressure, digestion, breathing, temperature regulation, and circulation.
POTS is characterized by an abnormal increase in heart rate when moving from a lying or seated position to standing. Current diagnostic criteria typically include an increase of 30 beats per minute or more within the first ten minutes of standing. For children and adolescents, the threshold is generally 40 beats per minute or greater.
While the elevated heart rate is what defines POTS medically, it is rarely the symptom patients complain about most.
Instead, patients often experience:
Dizziness or lightheadedness when standing
Fatigue and exhaustion
Brain fog and difficulty concentrating
Headaches and migraines
Heart palpitations
Nausea and digestive issues
Tremors or shakiness
Sleep disturbances
Heat intolerance
Exercise intolerance
Weakness and low stamina
For some individuals, symptoms are relatively mild. For others, they can become debilitating. School attendance may suffer. Sports become difficult or impossible. Social activities become harder to enjoy. Many patients describe feeling trapped in a body that no longer responds the way it should.
The emotional impact can be just as significant as the physical symptoms. Anxiety, depression, frustration, and isolation are common among individuals living with POTS, particularly when their symptoms are dismissed or misunderstood.
The Different Types of POTS
Researchers have identified several different presentations of POTS, which helps explain why symptoms can vary so dramatically from person to person. Neuropathic POTS is associated with dysfunction within the peripheral nervous system, affecting blood vessel regulation and circulation.
Hyperadrenergic POTS involves elevated levels of stress hormones such as norepinephrine and is often associated with significant sympathetic nervous system activation.
Hypovolemic POTS is linked to lower blood volume, making it difficult for the body to maintain adequate circulation when standing.
Some patients also have autoimmune conditions that appear to contribute to their symptoms. Research suggests that approximately 20% of POTS patients have a coexisting autoimmune disorder such as lupus or Sjögren's syndrome. Understanding these different presentations helps explain why there is rarely a one-size-fits-all solution for POTS. Each patient has a unique combination of contributing factors that must be considered.
One of the Biggest Misconceptions About POTS
Perhaps one of the most damaging misconceptions surrounding POTS is the belief that it is simply anxiety. Because symptoms like rapid heart rate, palpitations, dizziness, and sweating can resemble anxiety, many patients are told their symptoms are psychological in nature.
Research tells a different story. Studies have repeatedly shown that POTS is a physiological condition involving measurable dysfunction within the Autonomic Nervous System. While anxiety can certainly develop as a result of living with a chronic condition, anxiety is not typically the root cause of POTS.
Imagine constantly wondering if you'll feel faint when you stand up. Imagine not knowing whether you'll have enough energy to make it through school or work. Imagine experiencing symptoms that many people around you cannot see or understand.
It is not surprising that anxiety develops under those circumstances. For many patients, anxiety is a consequence of POTS, not the cause.
Understanding the Autonomic Nervous System
To understand the neurological side of POTS, it helps to understand how the Autonomic Nervous System works. We often explain it using the analogy of a car.
The Sympathetic Nervous System acts like the gas pedal. It prepares the body to respond to challenges by increasing heart rate, blood pressure, alertness, and energy output. The Parasympathetic Nervous System acts like the brake pedal. It promotes recovery, digestion, regulation, healing, and relaxation.
A healthy nervous system constantly adjusts between these two branches depending on the body's needs. When you exercise, the gas pedal increases activity. When you relax or sleep, the brake pedal takes over.
In POTS, this balance often becomes disrupted. Many patients demonstrate a pattern called dysautonomia, where sympathetic activity becomes excessive while parasympathetic activity struggles to keep up. It's as if the gas pedal is stuck partially down while the brake pedal becomes weak and ineffective.
This imbalance contributes to many of the hallmark symptoms associated with POTS.
Heart rate increases excessively. Blood vessel regulation becomes impaired. Blood pools in the lower extremities. Dizziness occurs. Fatigue develops. The body struggles to adapt to everyday positional changes.
The Hidden Role of Dysautonomia
Dysautonomia doesn't just affect heart rate. Because the Autonomic Nervous System influences nearly every organ system, dysfunction can create symptoms throughout the body. Patients commonly experience digestive issues because the parasympathetic system helps regulate gut motility and digestion. Sleep problems become common because autonomic balance is essential for healthy sleep cycles. Temperature regulation may become impaired, leading to heat intolerance or excessive sweating.
This is one reason POTS often feels so complex. Symptoms may seem unrelated, but they are frequently connected through the same underlying nervous system dysfunction.
The Perfect Storm Behind POTS
Like many chronic neurological conditions, POTS rarely develops because of a single event. Instead, many patients experience what PX Docs refers to as the "Perfect Storm," a combination of factors that gradually overwhelm the nervous system's ability to regulate itself.
Research has identified several contributors that may play a role. Genetics appear to influence susceptibility, with some patients reporting family members who also experience autonomic dysfunction. Viral infections are another common trigger. Many patients can trace the onset of symptoms back to illnesses such as mononucleosis, influenza, or other significant infections. Hormonal shifts may also contribute, which may help explain why POTS is more common among adolescent girls and young women.
Chronic stress, whether physical or emotional, places additional demands on the nervous system and may worsen autonomic dysregulation over time. Autoimmune conditions, physical deconditioning, inflammation, and environmental stressors may all contribute as well.
The end result is a nervous system that loses its ability to adapt appropriately to everyday demands.
Looking Deeper: The Brainstem and Upper Neck Connection
One of the most interesting areas of emerging research involves the relationship between POTS, the brainstem, and the upper cervical spine. The brainstem serves as a major control center for autonomic function. It helps regulate heart rate, blood pressure, breathing, balance, and communication between the brain and body.
Studies have identified structural and functional differences within the brainstem of some POTS patients, suggesting that this region may play a significant role in symptom development. The upper cervical spine is equally important because it surrounds and protects these delicate neurological structures. When abnormal tension, restriction, or dysfunction develops in this area, communication between the brain and body can become less efficient. Many POTS patients also experience chronic neck tension, upper back tightness, headaches, and postural challenges. These patterns often reflect deeper neurological stress that may contribute to autonomic dysfunction.
This is one reason many neurologically-focused providers pay close attention to the relationship between the upper neck, brainstem, and Autonomic Nervous System.
How Neurologically-Focused Chiropractic Care Fits In
At Ozark Family Chiropractic, we approach conditions like POTS from a nervous system perspective. Rather than focusing exclusively on symptom management, we ask a deeper question: How well is the nervous system functioning?
Using INSiGHT Scans, we evaluate patterns of nervous system stress and dysregulation. These non-invasive scans measure factors such as Heart Rate Variability (HRV), muscle tension, and autonomic balance.
These scans do not diagnose POTS. Instead, they help us identify areas where the nervous system may be struggling to adapt and regulate. When patterns of neurological stress are identified, we use gentle Neurologically-Focused Chiropractic adjustments designed to support healthier communication between the brain and body.
The goal is not to chase symptoms. The goal is to help the nervous system function more efficiently so the body can regulate itself more effectively. Many patients report improvements in energy, sleep, focus, recovery, stress resilience, and overall quality of life as nervous system regulation improves.
Lifestyle Strategies That Can Support POTS Recovery
Neurologically-Focused Chiropractic Care works best as part of a comprehensive approach. Several lifestyle strategies may help support nervous system function and improve symptom management.
Hydration remains one of the most important tools for many POTS patients. Drinking adequate water and electrolyte-rich fluids can help support blood volume and circulation. Increasing salt intake, when appropriate and under medical guidance, may also help some individuals maintain better blood pressure regulation.
Compression garments can reduce blood pooling and improve circulation throughout the day. Recumbent exercises such as swimming, rowing, and recumbent cycling often allow patients to improve cardiovascular conditioning without significantly worsening symptoms. Prioritizing nutrient-dense foods, adequate sleep, and stress management practices can further support nervous system health.
While no single strategy works for everyone, combining multiple supportive approaches often produces the best outcomes.
Moving Forward With Hope
Living with POTS can be incredibly challenging, but it is important to remember that symptoms are not random. They are signals that the body is struggling to regulate itself.
The more we learn about the nervous system, dysautonomia, and autonomic regulation, the more opportunities we have to help patients move beyond symptom management and toward meaningful improvement.
If you or someone you love is struggling with dizziness, fatigue, brain fog, rapid heart rate, or other symptoms associated with POTS, it may be worth looking beyond the cardiovascular system alone and evaluating how the nervous system is functioning.
Sometimes the missing piece isn't found in another medication or another test.
Sometimes it's found by helping the nervous system do what it was designed to do.
