Fibromyalgia is best known for its widespread pain, fatigue, and brain fog—but many patients notice symptoms that don’t fit neatly into the usual
description. Things like dizziness, racing heart, digestive issues, or feeling
faint when standing up. These problems may not just be “random fibro quirks”—they could point to dysautonomia,
a dysfunction of the autonomic nervous system.
Emerging research
shows that dysautonomia and fibromyalgia often travel together, and recognizing this hidden
connection can unlock new treatment strategies and much-needed validation for
patients.
What Is Dysautonomia?
Dysautonomia is a broad term for conditions where
the autonomic nervous system (ANS) doesn’t work properly. The
ANS controls involuntary functions such as:
- Heart
rate
- Blood
pressure
- Digestion
- Sweating
- Temperature
regulation
When it malfunctions,
patients experience a variety of symptoms
that often get mistaken for anxiety or “all in your head.”
Types of Dysautonomia
Seen in Fibromyalgia
The most common forms
linked with fibro include:
- Postural
Orthostatic Tachycardia Syndrome (POTS): Heart
rate spikes by 30+ beats per minute when standing.
- Neurally
Mediated Hypotension (NMH): Sudden
drops in blood pressure causing fainting or dizziness.
- Orthostatic
Intolerance (OI): Inability
to tolerate standing for long without feeling weak or lightheaded.
Overlapping Symptoms: Fibro or Dysautonomia?
Many dysautonomia symptoms overlap with fibromyalgia, making diagnosis tricky:
- Dizziness
or lightheadedness
- Rapid
heartbeat or palpitations
- Fatigue
and exercise intolerance
- Brain
fog
and poor concentration
- Digestive
issues (IBS-like symptoms)
- Heat
or cold intolerance
- Sweating
abnormalities
Patients often think
these are just fibro
flares—but they may be signs of an underlying autonomic problem.
Why Fibromyalgia and Dysautonomia Are Linked
Researchers believe
the connection may be due to:
- Autonomic
Nervous System Dysfunction
Fibro itself is considered a disorder of nervous system regulation. Dysautonomia may simply be another expression of this dysfunction. - Small-Fiber
Neuropathy
Up to half of fibro patients show evidence of small-fiber nerve damage, which affects autonomic regulation. - Inflammation
and Immune Dysfunction
Immune system irregularities in fibro may also disrupt autonomic signaling. - Shared
Triggers
Stress, infections, trauma, and hormonal changes can trigger both fibromyalgia and dysautonomia.
How Doctors Diagnose Dysautonomia in Fibro Patients
Common tests include:
- Tilt
table test: Monitors heart rate and
blood pressure when moving from lying down to standing.
- 24-hour
heart monitoring: Detects
irregularities in heart rate.
- Sweat
tests: Evaluates autonomic nerve
function.
What Helps: Managing
Dysautonomia in Fibromyalgia
Lifestyle Approaches
- Increase
fluids & electrolytes to
support blood pressure.
- Compression
garments to reduce blood pooling
in the legs.
- Gentle
movement (like recumbent exercise
or yoga) to condition the cardiovascular system.
- Pacing
and rest to prevent overexertion.
Medications (if prescribed)
- Beta
blockers (to manage heart rate spikes)
- Fludrocortisone
or midodrine (to stabilize blood pressure)
- Neuropathic
pain
medications (if small-fiber neuropathy is involved)
Supportive Care
- Work
with both a fibro specialist and
an autonomic disorder specialist.
- Keep
a symptom diary to identify triggers like heat,
dehydration, or prolonged standing.
Real Patient Voices
- Leah,
40: “I thought my dizziness
was just another weird fibro symptom. Getting a POTS diagnosis finally explained why I couldn’t stand in line without
nearly fainting.”
- Marcus,
53: “Compression socks and
extra salt changed everything. My heart no longer races every time I
stand.”
- Sofia,
38: “Knowing my fibro
and dysautonomia were connected helped me stop blaming myself. It’s my
nervous system, not my willpower.”
Frequently Asked
Questions
1. Is dysautonomia
part of fibromyalgia?
Not officially, but studies show it’s common in fibro patients—likely due to shared nervous system
dysfunction.
2. How do I know if I
have dysautonomia or just fibro flares?
If you have dizziness, fainting, or extreme heart rate changes when standing,
dysautonomia should be evaluated.
3. Can treating
dysautonomia improve fibromyalgia symptoms?
Yes. Managing autonomic dysfunction can reduce fatigue, brain fog, and flare severity.
4. What kind of doctor diagnoses dysautonomia?
Usually a cardiologist or neurologist with experience in
autonomic disorders.
5. Does every fibro patient have dysautonomia?
No. But studies suggest a significant overlap, especially in severe
fibro cases.
6. Is dysautonomia
dangerous?
Not usually life-threatening, but it can be disabling. Proper management
improves safety and quality of life.
Final Thoughts
Dysautonomia is
a hidden but important piece of the fibromyalgia puzzle. For many patients, it explains symptoms that don’t fit the classic fibro profile—like dizziness, fainting, or a racing
heart.
Recognizing the fibro–dysautonomia connection empowers patients and
doctors to treat the whole nervous system, not
just the pain. With proper management, patients can reduce
flares, avoid scary symptoms,
and regain a greater sense of control.
Fibromyalgia is complex, but every new piece of the puzzle brings us closer
to better care—and better lives.
