POTS Symptoms – Why Your Heart Races, You Feel Dizzy, and Doctors Keep Missing It

Have you ever stood up from a chair only to feel your heart racing, your vision dimming, or a sudden wave of dizziness? Maybe you’ve been told it’s anxiety, stress, dehydration, or that your lab work is normal. Yet the symptoms continue.

For many people, these unexplained issues are signs of Postural Orthostatic Tachycardia Syndrome (POTS), a condition affecting the body’s autonomic nervous system. Unfortunately, POTS is often misunderstood, frequently misdiagnosed, and can leave patients searching for answers for years.

At our office, we commonly meet patients who have been told everything is normal despite experiencing debilitating symptoms. Understanding the connection between the nervous system, brainstem, upper cervical spine, and autonomic regulation may provide important insights into why these symptoms occur.

What Is POTS?

Postural Orthostatic Tachycardia Syndrome (POTS) is a type of autonomic nervous system disorder that affects how the body regulates blood pressure, circulation, and heart rate when changing positions.

Normally, when you stand up, your nervous system automatically constricts blood vessels and adjusts heart rate to maintain adequate blood flow to the brain.

In someone with POTS, this response is impaired. Blood tends to pool in the lower body, forcing the heart to work harder to maintain circulation. As a result, patients often experience significant heart rate spikes on standing along with a variety of neurological symptoms.

Common POTS Symptoms

While symptoms vary from person to person, some of the most common POTS symptoms include

Rapid heart rate when standing

Lightheadedness when standing

Dizziness or feeling faint

Chronic fatigue

Exercise intolerance

Headaches

Migraines

Difficulty concentrating

Brain fog

Digestive disturbances

Sleep issues

Temperature regulation problems

Many patients report that even routine daily activities such as grocery shopping, showering, or standing in line become exhausting.

POTS and Dizziness - Why Do Patients Feel So Unsteady?

One of the most common complaints among POTS patients is dizziness.

POTS and dizziness are closely linked because the brain may temporarily receive inadequate blood flow when the body’s autonomic control systems fail to respond appropriately to position changes.

Patients frequently describe

Some individuals feel as though they are constantly being pulled to one side or struggle with spatial awareness and coordination.

Brain Fog and Fatigue - The Hidden Symptoms of POTS

While the rapid heart rate often gets the most attention, many patients say that brain fog and fatigue are actually the most disabling aspects of the condition.

Common cognitive symptoms include

These symptoms may occur because the brain is not receiving consistent blood flow and oxygen delivery throughout the day.

POTS Symptoms in Women

Research shows that approximately 80% of POTS patients are female, making POTS symptoms in women especially important to recognize.

Symptoms often emerge or worsen during periods of hormonal fluctuation, including

Unfortunately, many women are initially told their symptoms are anxiety-related before receiving a proper POTS diagnosis.

Dysautonomia vs POTS - What's the Difference?

Many people hear the term dysautonomia and wonder how it differs from POTS.

The easiest way to understand the dysautonomia vs POTS difference is that dysautonomia is the broader category.

Dysautonomia refers to any condition involving dysfunction of the autonomic nervous system. POTS is one specific form of dysautonomia characterized primarily by excessive heart rate increases when standing.

In other words

Other dysautonomia symptoms may include digestive issues, abnormal sweating, blood pressure instability, temperature intolerance, and fainting episodes.

Can Upper Cervical Nerve Compression Cause Symptoms?

Patients often ask whether upper cervical nerve compression can create symptoms throughout the body.

The upper cervical spine contains several important neurological structures, including

Dysfunction in this region may contribute to:

For some patients, correcting upper cervical dysfunction may help reduce stress throughout the entire cervical spine.

Upper Cervical Chiropractic for a Pinched Nerve in the Neck

Many individuals seeking chiropractic for a pinched nerve are looking for a conservative, non-surgical option.

At Upper Cervical Specialists of Atlanta, our approach focuses on identifying structural abnormalities involving the atlas (C1) and axis (C2) through advanced imaging and precise biomechanical analysis.

Rather than forceful twisting or cracking of the neck, upper cervical adjustments are designed to be highly specific and individualized.

The goal is to improve spinal alignment, reduce abnormal stress patterns, and optimize nervous system function.

The Brainstem and Nervous System Connection

The autonomic nervous system depends heavily on proper communication between the brainstem and the rest of the body.

The brainstem and nervous system work together to regulate

Within the brainstem are critical autonomic control centers that continuously monitor the body’s internal environment and make adjustments to maintain stability.

When this communication becomes disrupted, autonomic symptoms may develop.

The Role of the Vagus Nerve

The vagus nerve is one of the most important nerves involved in autonomic regulation.

Some researchers have investigated whether vagus nerve dysfunction may contribute to symptoms experienced by individuals with POTS and other autonomic disorders.

The vagus nerve influences

Because portions of the vagus nerve originate within the brainstem, many clinicians have become interested in factors that may influence brainstem function.

The Upper Cervical Spine and Autonomic Function

The upper cervical spine consists of the atlas (C1) and axis (C2), the two vertebrae located directly beneath the skull.

These structures surround and protect the lower brainstem while housing thousands of specialized neurological receptors that continuously communicate information regarding posture, balance, and head position.

An atlas C1 misalignment may alter normal biomechanical function and affect the quality of neurological information being transmitted between the neck and the brain.

Because the upper cervical spine sits in such close proximity to important autonomic control centers, some healthcare providers investigate whether upper cervical dysfunction may contribute to autonomic symptoms.

The Relationship Between POTS and Upper Cervical Spine Dysfunction

Many patients diagnosed with POTS report a history of

This has led researchers and clinicians to explore the relationship between POTS and upper cervical spine dysfunction.

The upper cervical region contains one of the highest concentrations of proprioceptive receptors in the entire body. These receptors provide constant feedback to the brainstem regarding body position and movement.

When this communication becomes altered, it may contribute to disturbances involving balance, autonomic regulation, dizziness, and coordination.

While more research is needed, this relationship continues to gain increasing clinical attention.

Can Upper Cervical Chiropractic Help POTS?

Many individuals seek upper cervical chiropractic for POTS after struggling to find answers through traditional approaches alone.

Upper cervical chiropractic focuses on evaluating and correcting structural abnormalities involving the atlas (C1) and axis (C2) using precise imaging and gentle adjustments.

The goal is not to treat POTS directly, but rather to improve spinal alignment, reduce neurological stress, and optimize communication between the upper cervical spine and nervous system.

Many patients report improvements in

Upper cervical care is often utilized as part of a collaborative healthcare approach alongside cardiologists, neurologists, primary care physicians, and other healthcare providers.

Why POTS Is Frequently Missed

One of the biggest challenges facing POTS patients is obtaining an accurate diagnosis.

Many individuals spend years being told

Because standard blood work and imaging studies often appear normal, autonomic disorders can easily go unrecognized.

If you experience persistent dizziness, rapid heart rate when standing, chronic fatigue, or unexplained neurological symptoms, it may be worthwhile to discuss autonomic testing and a comprehensive neurological evaluation with your healthcare provider.

Final Thoughts

POTS is much more than a rapid heart rate. It is a complex disorder involving the autonomic nervous system, brainstem, circulation, and neurological regulation.

Understanding the connection between the autonomic nervous system, vagus nerve, brainstem, and upper cervical spine may provide valuable insight into why symptoms develop and why many patients struggle to find answers.

If you are experiencing persistent POTS symptoms, dizziness, brain fog, fatigue, or lightheadedness when standing, a comprehensive evaluation that includes both autonomic and upper cervical considerations may help uncover contributing factors that have previously been overlooked.

Looking for a Natural Approach to POTS Symptoms?

Living with POTS can be frustrating, especially when you’ve been told your symptoms are “normal” or simply anxiety. Many patients spend years searching for answers while continuing to struggle with dizziness, rapid heart rate, fatigue, brain fog, and an inability to enjoy everyday activities.

At Upper Cervical Specialists of Atlanta, we take a neurological approach to evaluating patients with POTS and dysautonomia symptoms. Through advanced imaging and precise upper cervical analysis, we assess whether dysfunction within the upper cervical spine may be contributing to abnormal communication between the brainstem, autonomic nervous system, and the rest of the body.

While upper cervical chiropractic is not a treatment or cure for POTS, many patients seek care to improve nervous system function, reduce neurological stress, and support the body’s ability to regulate itself more effectively. If you’re looking for a comprehensive evaluation and want to explore whether the upper cervical spine may be playing a role in your symptoms, our team is here to help.
