Dysautonomia: When Your Autonomic Nervous System Malfunctions

Discover how Serenity Health Care Center’s comprehensive approach helps identify and treat the various forms of dysautonomia that conventional medicine often misses or misdiagnoses.

Understanding Dysautonomia: The Hidden Health Disruptor

Dysautonomia—a term unfamiliar to many despite affecting millions—refers to a group of conditions caused by dysfunction of the autonomic nervous system (ANS). This sophisticated control network regulates all of your body’s automatic functions: heart rate, blood pressure, digestion, temperature control, pupil dilation, sweating, and countless other processes that occur without conscious effort.

When this system malfunctions, the effects can be widespread and debilitating, impacting virtually every organ system and aspect of daily life. Despite its prevalence, dysautonomia remains widely under-recognized, with patients often spending years seeking answers for their complex, shifting symptoms.

The Many Faces of Dysautonomia: Types and Classifications

Dysautonomia is not a single condition but rather an umbrella term encompassing several distinct disorders:

Postural Orthostatic Tachycardia Syndrome (POTS)

The most common form of dysautonomia, POTS affects an estimated 1-3 million Americans and is characterized by:

• Excessive heart rate increase upon standing (30+ bpm increase within 10 minutes)
• Blood pooling in the lower extremities
• Reduced cerebral blood flow
• Exercise intolerance
• Fatigue and cognitive difficulties (“brain fog”)
• Possible fainting or near-fainting episodes

POTS is most common in women of childbearing age but can affect people of any age or gender.

Neurocardiogenic Syncope (NCS)

Also known as vasovagal syncope, this condition involves:

• Inappropriate triggering of the vagus nerve
• Sudden drop in blood pressure and/or heart rate
• Fainting or near-fainting episodes
• Triggers may include standing, heat, emotional stress, pain, or specific situations

Orthostatic Hypotension (OH)

This form of dysautonomia presents with:

• Significant blood pressure drop upon standing
• Dizziness or lightheadedness when upright
• Visual disturbances when standing
• Difficulty remaining upright for extended periods
• Increased symptoms after eating or in warm environments

Inappropriate Sinus Tachycardia (IST)

This condition manifests as:

• Abnormally high resting heart rate
• Excessive heart rate response to minimal exertion
• Persistent palpitations
• Fatigue and exercise intolerance
• Symptoms resembling anxiety but with physiological cause

Autonomic Neuropathy

This form involves actual damage to the autonomic nerves and can include:

• Digestive dysfunction (gastroparesis, constipation, diarrhea)
• Urinary problems (incontinence, retention)
• Sexual dysfunction
• Sweat gland abnormalities
• Temperature regulation problems
• Often associated with diabetes, autoimmune conditions, or toxic exposures

Multiple System Atrophy (MSA)

A rare, serious neurodegenerative form of dysautonomia characterized by:

• Progressive autonomic failure
• Parkinson-like movement problems
• Cerebellar ataxia (coordination difficulties)
• Rapid progression
• Usually appearing in adults over 40

The Symptom Constellation: Why Dysautonomia Is Often Missed

One of the most challenging aspects of dysautonomia is the wide range and seemingly unrelated nature of its symptoms:

Cardiovascular Symptoms

• Rapid, slow, or irregular heartbeat
• Blood pressure fluctuations
• Blood pooling in extremities
• Chest discomfort or palpitations
• Exercise intolerance
• Cold or purple hands and feet

Neurological Symptoms

• Brain fog and cognitive impairment
• Headaches or migraines
• Dizziness and lightheadedness
• Weakness
• Tremor
• Sleep disturbances
• Visual disturbances

Gastrointestinal Symptoms

• Nausea and vomiting
• Early satiety (feeling full quickly)
• Bloating and abdominal pain
• Constipation and/or diarrhea
• Difficulty swallowing
• Gastroparesis (delayed stomach emptying)

Urinary and Reproductive Symptoms

• Bladder dysfunction
• Urinary frequency or urgency
• Sexual dysfunction
• Menstrual irregularities
• Heightened symptoms during hormonal shifts

Other Common Symptoms

• Fatigue and exercise intolerance
• Temperature regulation problems
• Inappropriate or absent sweating
• Sensitivities to light, sound, and chemicals
• Anxiety-like symptoms (trembling, chest tightness)
• Breathing difficulties
• Dry eyes and mouth

This vast array of symptoms often leads to misdiagnosis, with patients frequently labeled with anxiety disorders, depression, chronic fatigue syndrome, or fibromyalgia before the underlying autonomic dysfunction is identified.

Root Causes and Triggers: Why Dysautonomia Develops

Dysautonomia can emerge from various underlying factors:

Genetic Predisposition

• Family history of autonomic disorders

Infection-Triggered

• Post-viral syndromes (including post-COVID dysautonomia)
• Lyme disease and co-infections
• Epstein-Barr virus
• Mycoplasma pneumoniae
• Streptococcal infections

Autoimmune-Mediated

• Autoantibodies against autonomic receptors
• Sjögren’s syndrome
• Guillain-Barré syndrome
• Autoimmune small fiber neuropathy
• Autoimmune encephalitis

Toxin-Induced

• Heavy metal exposure
• Environmental chemical sensitivity
• Mold and mycotoxin exposure
• Medication side effects
• Alcohol-related autonomic damage

Trauma-Related

• Traumatic brain injury
• Spinal cord injury
• Surgery complications
• Psychological trauma affecting neurodevelopment

Metabolic and Endocrine

Success Stories: Finding Hope with Proper Diagnosis and Treatment

“After collapsing at work and spending three years being told my symptoms were anxiety or depression, I finally found Serenity Health Care Center. Their comprehensive autonomic testing diagnosed POTS and underlying Lyme disease. With their multifaceted treatment approach—addressing both the infection and autonomic dysfunction—I’ve regained 80% of my former functioning. I can now work part-time, exercise carefully, and have a social life again.” – Jennifer R.

“My teenage daughter developed severe dysautonomia after a viral infection. Her pediatrician and even specialists couldn’t offer more than symptom management that barely helped. Serenity’s approach identified autoimmune autonomic ganglionopathy as the cause and developed a comprehensive treatment plan. Six months later, she’s back in school full-time and even playing tennis again after being predominantly bedbound.” – Michael T., parent

“Post-COVID, I developed debilitating symptoms that multiple doctors either dismissed or misdiagnosed. Serenity’s autonomic testing confirmed dysautonomia and their root-cause approach identified ongoing inflammation and mast cell activation. Their comprehensive protocol—addressing both the autonomic dysfunction and underlying immune dysregulation—has given me steady improvement when nothing else helped.” – Sarah K.

Is It Dysautonomia? When to Suspect Autonomic Dysfunction

Consider evaluation for dysautonomia if you experience:

• Dizziness, lightheadedness, or fainting when standing
• Extreme fatigue not relieved by rest
• Exercise intolerance with post-exertional symptom flares
• Racing heart with minimal exertion
• Digestive problems without clear structural cause
• Temperature regulation issues (feeling too hot/cold)
• Sensitivity to light, sound, or chemicals
• Brain fog and cognitive difficulties
• Multiple symptoms affecting different body systems
• Symptoms that worsen with heat, standing, or after meals
• Being told “all your tests are normal” despite significant symptoms
