Autonomic Dysfunction

What Is Dysautonomia?

If tests show nothing wrong but you keep feeling sick,
it may be your autonomic nervous system.

Heart rate, breathing, digestion, temperature regulation — the autonomic nervous system controls all of these involuntary functions. Dysautonomia occurs when this system stops working properly. If you experience unexplained palpitations, dizziness, anxiety, insomnia, or chronic fatigue, your autonomic nervous system may be the cause.

Autonomic Nervous System

What does the autonomic nervous system do?

The autonomic nervous system is a self-regulating system that controls your body without conscious effort. It manages heart rate, breathing, digestion, body temperature, and sleep 24/7, and is divided into two branches: the sympathetic and parasympathetic nervous systems.

Sympathetic

Sympathetic Nervous System — The Accelerator

Activated during danger or stress. It increases heart rate, raises blood pressure, and speeds up breathing, putting your body into an alert, fight-or-flight mode.

Parasympathetic

Parasympathetic Nervous System — The Brake

Responsible for rest and recovery. It aids digestion, lowers heart rate, and supports sleep and immune recovery. The vagus nerve is the most prominent parasympathetic nerve.

These two systems must be in balance for the body to function normally.
When the balance is disrupted, the problem affects the entire body's regulation, not just a single organ.

Symptoms

What symptoms does dysautonomia cause?

Symptoms may appear individually or in combination. If the following symptoms recur, we recommend getting an autonomic function test.

Palpitations
Dizziness
Anxiety / Panic
Shortness of Breath
Chronic Fatigue
Sleep Problems
Orthostatic Hypotension
Digestive Issues
Brain Fog
Recurring Headaches
Cold Extremities
Tinnitus
Causes

What causes dysautonomia?

A single cause is rare; multiple factors often overlap. The more of these factors are present, the more likely autonomic imbalance becomes.

01

Chronic Stress

Prolonged stress over-activates the sympathetic nervous system while reducing parasympathetic recovery capacity.

02

Sleep Deprivation

During sleep, the parasympathetic system activates for bodily recovery. Lack of sleep immediately disrupts autonomic balance.

03

Postural Issues (Cervical Spine)

Forward head posture and cervical spine misalignment can compress and irritate autonomic nerve pathways running along the spine.

04

Hormonal Changes

Menopause, menstrual cycles, and thyroid fluctuations can impact the autonomic nervous system's regulatory centers.

05

Post-Traumatic Neural Sensitization

After car accidents, falls, or severe psychological trauma, the autonomic nervous system may become hypersensitive, causing symptoms to persist.

06

Hyperventilation Habits

Unconscious shallow, rapid breathing lowers blood CO2 levels, causing dizziness, numbness, and anxiety.

Our Approach

How does OSANG treat dysautonomia differently?

OSANG Neurosurgery employs both a neurosurgeon and a neurologist working together. We examine structural causes such as cervical and thoracic spine issues alongside functional autonomic imbalances, and restore autonomic balance through two proprietary treatment programs.

Program 01

Neural Reset Protocol

A treatment protocol that calms the overactivated sympathetic nervous system and restores parasympathetic (vagus nerve) function.

Program 02

NPT Program

OSANG's proprietary non-surgical physical therapy that delivers direct stimulation to autonomic and peripheral nerve pathways.

Diagnosis

How is dysautonomia diagnosed?

Autonomic dysfunction often goes undetected by standard tests. OSANG Neurosurgery uses a 4-step diagnostic process to identify the type of imbalance and its underlying causes.

STEP 01

Symptom Interview & Medical History

We carefully review your current symptoms, onset timing, lifestyle habits, and past medical history. The pattern of symptom occurrence itself is a critical diagnostic clue.

STEP 02

HRV Test (Heart Rate Variability Analysis)

Quantitatively measures the balance between sympathetic and parasympathetic activity. This objectively shows the type and degree of imbalance.

STEP 03

Neurological & Imaging Tests

Checks for structural issues in the cervical and thoracic spine. MRI, X-ray, and other imaging may be performed as needed.

STEP 04

Specialist Consultation & Personalized Treatment Plan

Our neurosurgeon and neurologist review test results together and design a treatment plan tailored to each patient.

"If you've been told tests show nothing wrong but symptoms persist,
you need a specialized autonomic function assessment."

FAQ

Frequently Asked Questions About Dysautonomia

Q. What is dysautonomia?
Dysautonomia is a condition where the autonomic nervous system — which controls involuntary functions like heart rate, breathing, digestion, and temperature regulation — malfunctions. An imbalance between the sympathetic and parasympathetic nervous systems leads to unexplained palpitations, dizziness, anxiety, insomnia, and chronic fatigue. Because it affects the regulatory system itself rather than a specific organ, standard tests often fail to identify the cause.
Q. Are dysautonomia and panic disorder the same thing?
They are not the same. Panic disorder is a type of anxiety disorder characterized by sudden, intense fear and acute attacks. Dysautonomia is a broader imbalance of the autonomic nervous system. However, autonomic imbalance can trigger panic-like symptoms, and many panic disorder patients also have autonomic dysfunction, making accurate differential diagnosis important.
Q. Tests show nothing wrong — why do I have these symptoms?
Standard blood tests, ECGs, and endoscopies check for structural organ abnormalities. Functional autonomic issues may not be detected by these tests. Specialized autonomic function tests such as HRV (Heart Rate Variability) analysis can quantitatively measure the imbalance between sympathetic and parasympathetic activity.
Q. Which department treats dysautonomia?
Dysautonomia can be treated by neurology, neurosurgery, and psychiatry departments. OSANG Neurosurgery employs both a neurosurgeon and a neurologist who collaborate to simultaneously analyze structural causes (cervical/thoracic spine) and functional autonomic abnormalities.
Q. How long does treatment take?
This depends on the type and chronicity of symptoms. Generally, treatment requires 4-8 weeks or more, and chronic cases may take longer. With accurate diagnosis, systematic treatment, and lifestyle modifications, most patients experience meaningful improvement.
Q. Is treatment covered by health insurance?
Basic diagnostic tests and consultations may be covered by Korean national health insurance. OSANG's proprietary programs, including the NPT Program and Neural Reset Protocol, are non-covered items. Please contact us for detailed pricing information.
