Fibromyalgia and
postural orthostatic tachycardia syndrome (POTS) are two complex conditions
that can cause a range of debilitating symptoms, including fatigue,
dizziness, brain fog, and widespread discomfort. Because they share certain
overlapping features, many people wonder whether their symptoms point to fibromyalgia, POTS,
or both. While these conditions can coexist, they are distinct diagnoses with
different underlying mechanisms, diagnostic criteria, and treatment approaches.
Understanding the key differences between fibromyalgia and
POTS is essential for accurate diagnosis and effective management. This
detailed guide explains how these conditions differ and what you need to know
to better advocate for your health.
Understanding Fibromyalgia
Fibromyalgia is a chronic pain
condition that affects how the brain and nervous system process pain signals.
It is characterized by widespread musculoskeletal pain, fatigue, sleep
disturbances, and cognitive difficulties often referred to as fibro fog. People
with fibromyalgia may
also experience headaches, irritable bowel symptoms, sensitivity to noise,
light or touch, and mood disorders such as anxiety or depression. The exact
cause of fibromyalgia is not
fully understood, but research points to a combination of genetic,
environmental, and neurobiological factors that result in an amplified pain response.
Understanding POTS
POTS is a form of dysautonomia, which means it involves
dysfunction of the autonomic nervous system. The hallmark feature of POTS is an
exaggerated increase in heart rate when moving from lying down to standing,
usually accompanied by lightheadedness, palpitations, fatigue, and sometimes
fainting. Additional symptoms can
include brain fog, exercise
intolerance, nausea, shakiness, and sweating abnormalities. POTS is often
triggered by events such as a viral illness, trauma, or surgery, and it may be
associated with autoimmune disorders, connective tissue diseases, or small
fiber neuropathy.
Key Differences in Cause
Fibromyalgia is
primarily a disorder of pain processing in the central nervous system. It is
not caused by structural damage, inflammation, or cardiovascular dysfunction.
POTS, on the other hand, arises from problems with how the autonomic nervous
system regulates blood flow and heart rate. In POTS, the body struggles to
maintain stable blood pressure and heart rate during changes in posture,
leading to symptoms that
are closely tied to standing or prolonged sitting.
Differences in Symptom Triggers
In fibromyalgia, symptoms such as pain and fatigue
are often triggered by physical exertion, stress, poor sleep, or sensory
overload. While symptoms may
fluctuate throughout the day, they are not directly related to posture. In
contrast, POTS symptoms are
clearly linked to changes in body position. People with POTS typically feel
worse upon standing and may feel better when lying down. Activities that
require prolonged upright posture, such as standing in line or showering, often
trigger or worsen symptoms in
POTS.
Differences in Diagnostic Testing
Fibromyalgia is
diagnosed based on a combination of symptom history and physical exam findings.
There are no definitive blood tests or imaging studies that confirm fibromyalgia,
although testing may be done to rule out other conditions. Diagnosis is
typically made when widespread pain has persisted for at least three months,
along with associated symptoms like
fatigue and cognitive difficulty.
POTS is diagnosed through objective testing that measures
heart rate and blood pressure changes upon standing. A common tool is the tilt
table test or active stand test. POTS is diagnosed when there is a sustained
increase in heart rate of at least 30 beats per minute within 10 minutes of
standing (or 40 beats per minute in adolescents) without a significant drop in
blood pressure.
Differences in Treatment Approaches
Treatment for fibromyalgia
focuses on reducing pain sensitivity, improving sleep, and enhancing function
through a combination of medications, physical therapy, gentle exercise,
stress management, and cognitive behavioral strategies. Medications may include
certain antidepressants, anticonvulsants, or muscle relaxants aimed at
modulating pain processing.
POTS treatment targets improving blood flow, heart rate
control, and managing symptoms. This
may include increasing salt and fluid intake, wearing compression garments,
medications such as beta blockers or fludrocortisone, and physical conditioning
programs focused on recumbent exercise.
Non-medication strategies such as elevating the head of the bed or avoiding
prolonged standing are also important.
Differences in Impact on Daily Life
Both conditions can significantly impact quality of life,
but in different ways. Fibromyalgia often
limits activity due to pain and fatigue regardless of posture. Tasks that
require sustained focus or repetitive movement may be challenging. POTS tends
to limit activities that involve being upright for extended periods, and people
may have to sit or lie down frequently to manage symptoms. The unpredictability of
heart rate and blood pressure changes in POTS can make routine activities like
shopping, cooking, or commuting particularly difficult.
Can You Have Both Fibromyalgia and
POTS?
Yes it is possible to have both conditions. In fact some
studies suggest a significant overlap between fibromyalgia and
POTS, possibly due to shared features of autonomic dysfunction or nervous
system hypersensitivity. When both conditions coexist, it is especially
important to have a coordinated treatment plan that addresses the unique
challenges of each.
Conclusion
While fibromyalgia and
POTS share some symptoms such
as fatigue, brain fog, and lightheadedness, they are distinct conditions with
different underlying causes,
triggers, and treatments.
Recognizing these differences is key to getting an accurate diagnosis and the
right care. If you experience symptoms of
either or both conditions, working with a knowledgeable healthcare provider who can
perform appropriate testing and guide your treatment is essential.
Understanding how fibromyalgia and
POTS differ helps you take informed steps toward managing your health and improving daily life.
FAQs
Can fibromyalgia cause
POTS
Fibromyalgia does
not cause POTS but some people have both conditions possibly due to overlapping
nervous system dysfunction.
How can I tell if my dizziness is from fibromyalgia or POTS
If dizziness is clearly linked to standing and relieved by lying down POTS may
be the cause. Fibromyalgia-related
dizziness is less tied to posture.
Are treatments for fibromyalgia and
POTS the same
No treatments differ because they
target different underlying issues. Fibromyalgia treatments focus on pain processing
while POTS treatments focus
on regulating heart rate and blood flow.
Should I see a specialist for POTS or fibromyalgia
Yes seeing a specialist such as a rheumatologist for fibromyalgia or a
cardiologist or neurologist familiar with POTS can provide more targeted care.
Is brain fog the same in fibromyalgia and
POTS
Both conditions can cause brain fog but in POTS it is often worse with standing
while in fibromyalgia it is
more constant and linked to overall fatigue and pain.
