Why So Many People with hEDS and POTS Continue to Struggle: A Structural Perspective

For many people living with hypermobile Ehlers-Danlos Syndrome (hEDS) or Postural Orthostatic Tachycardia Syndrome (POTS), everyday activities can become surprisingly difficult.

Putting away dishes, folding laundry, walking the dog, cleaning the house, or simply standing in a grocery store checkout line can leave them exhausted. Neck pain, headaches, dizziness, brain fog, digestive problems, joint instability, rapid heart rate, and overwhelming fatigue often occur together, creating a condition that can feel impossible to fully understand-let alone manage.

Fortunately, research continues to uncover important relationships between connective tissue health, autonomic nervous system function, posture, spinal structure and overall physiology. Rather than viewing these conditions as isolated collections of symptoms, a growing body of evidence suggests they are best understood as interacting systems within the human body.

At our office, we have found this perspective invaluable.

While hEDS and POTS do not always occur together, patients who experience both frequently present with significant postural abnormalities and structural instability. Objective evaluation through digital posture analysis and spinal radiographs often reveals substantial deviations in cervical and thoracic alignment that increase the mechanical demands placed upon an already vulnerable system.

In these patients, when structural correction towards normal values is actively pursued the result that we have witnessed time and again is restoration of healthier biomechanics and reduced unnecessary mechanical stress, thereby improving efficiency, and removing one of the many obstacles preventing these patients from functioning at their highest potential.

Understanding the Connection Between hEDS and POTS

Hypermobile Ehlers-Danlos Syndrome is an inherited connective tissue disorder characterized by joint hypermobility, ligament laxity, chronic pain, and tissue fragility. Because connective tissue exists throughout the body-including blood vessels, ligaments, skin, muscles, and internal organs-the effects extend far beyond flexible joints.

Many individuals with hEDS also develop Postural Orthostatic Tachycardia Syndrome, a form of autonomic nervous system dysfunction characterized by an excessive increase in heart rate upon standing. Symptoms commonly include dizziness, fatigue, exercise intolerance, lightheadedness, palpitations, and cognitive “brain fog.”

Research suggests that abnormalities in connective tissue may reduce the body’s ability to regulate blood vessel tone and venous return. The autonomic nervous system compensates by increasing heart rate in an attempt to maintain adequate circulation when standing.

This relationship has been consistently described in the scientific literature and helps explain why these conditions frequently coexist.

Why Does Structure Matter?

To understand why posture deserves consideration in hEDS and POTS, we first need to understand the relationship between the spine and the nervous system.
The nervous system is the body’s master control system. Every heartbeat, every breath, every digestive contraction, every muscle contraction, and every healing response depends upon continuous communication between the brain and the rest of the body.

A simple analogy helps illustrate this relationship.
The nervous system is the software of the human body.
The spine is the hardware that protects it.
Neither functions optimally when the other becomes compromised.
The outward expression of spinal structure is posture.

Posture is far more than appearance. It provides a window into how efficiently the body manages gravity, distributes mechanical loads, and protects the nervous system throughout daily life.

For individuals living with connective tissue disorders, this relationship becomes even more important.
Ligament laxity reduces passive stability. As a result, muscles must work harder simply to maintain an upright posture. Over months and years this increased demand may contribute to forward head posture, rounded shoulders, thoracic collapse, and progressive spinal instability.
This increased workload comes at a cost.

Energy that could otherwise support movement, healing, and normal physiology is instead redirected toward maintaining structural stability.

A Structural View of Physiology

One of the ideas we emphasize in our office is that the nervous system cannot be separated from the structure that protects it.

From a biomechanical perspective, progressive postural collapse increases abnormal loading of the spinal joints, discs, ligaments, and surrounding musculature. As postural muscles fatigue, the spine becomes increasingly dependent upon passive structures for stability.

These mechanical adaptations may alter proprioceptive input, sensorimotor integration, muscular coordination, and overall movement efficiency. For individuals already living with connective tissue disorders, this additional mechanical stress may compound existing autonomic dysfunction and contribute to the cycle of pain, fatigue, reduced movement, and diminished physiological reserve.

Importantly, this distinction matters.

Now, current research has not established poor posture as the direct cause of hEDS or POTS despite anecdotal, empirical, and clinical evidence in our office demonstrating that improvements in posture can improve the symptoms associated with these conditions. On the other hand, the available evidence strongly supports the conclusion that posture influences biomechanics, respiratory function, muscular demand, and overall physiological efficiency. Therefore, from our clinical perspective, these relationships deserve careful evaluation rather than dismissal.

This is why structural assessment forms an essential part of our approach.

Instead of asking only, “What diagnosis does this patient have?” we also ask, “What mechanical stresses might be increasing the physiological demands already imposed by that diagnosis?”

That question often changes the conversation entirely.

Why Isn’t Medication Alone Enough?

One of the defining characteristics of POTS is autonomic nervous system dysregulation. The autonomic nervous system regulates heart rate, blood pressure, breathing, circulation, digestion, hormone balance, and countless other functions without conscious effort.

Because these conditions involve neurotransmitters, hormones, circulation, and cellular metabolism, it is easy to conclude that they are purely chemical disorders.

They are not.

More accurately, they are conditions with important chemical, neurological, and structural components that frequently influence one another.
This distinction is important because chemistry does not exist independently of structure.

Connective tissue supports joints.
Muscles stabilize posture.
Posture influences breathing.
Breathing affects oxygen delivery.
Oxygen supports mitochondrial energy production.
Energy determines the body’s ability to maintain posture.
The cycle then begins again.

Rather than functioning as isolated systems, the human body operates through continuous biological feedback loops.

This is one reason many patients continue to struggle despite receiving appropriate medical management.

Medication may improve one aspect of physiology while leaving the underlying mechanical demands unchanged.

Likewise, structural correction without appropriate nutrition, rehabilitation, conditioning, hydration, or medical management may also produce incomplete results.

The body rarely responds to a single intervention because the body itself is not organized as a collection of isolated systems.

It functions as an integrated whole.

The Missing Piece: Supporting the Structure

Nutrition is another frequently overlooked component of this discussion.

Many individuals living with hEDS and POTS experience gastrointestinal dysfunction, delayed gastric emptying, reflux, nausea, abdominal discomfort, and altered bowel function. These challenges may impair the body’s ability to absorb and utilize the nutrients necessary to support healthy connective tissue, muscular endurance, and cellular energy production.

Research has identified deficiencies involving iron, vitamin B12, vitamin D, magnesium, and other nutrients in subsets of these patients. Although deficiencies vary from person to person, inadequate nutritional status may contribute to fatigue, slower tissue repair, reduced muscle performance, and decreased resilience.
This does not suggest that nutrition alone explains hEDS or POTS.

Rather, it illustrates that an already vulnerable system should not be expected to perform optimally when it lacks the resources required to support normal physiology.

In our clinical experience, individualized nutritional strategies, appropriate hydration, electrolyte support, and targeted supplementation frequently become important components of a comprehensive care plan.

A Comprehensive Strategy Makes the Most Sense

One of the most valuable lessons we have learned while caring for patients with hEDS and POTS is that meaningful improvement rarely comes from a single treatment.

Instead, successful management often requires addressing multiple contributors to function simultaneously over a plan of care, or strategy of healing.
At our office, this begins with objective evaluation rather than assumption.

Structural spinal analysis, digital posture assessment, and individualized recommendations help identify mechanical stressors that may be increasing the physiological demands already imposed by connective tissue disorders.

When appropriate, these findings are integrated with rehabilitation, nutritional support, breathing strategies, progressive conditioning, and evidence-informed chiropractic structural correction.

Our goal is not simply to reduce symptoms.
Our goal is to improve function.
Because when function improves, quality of life often follows.

Three Practical Steps You Can Take

1. Have Your Structure Professionally Evaluated
   Many people living with hEDS or POTS have never undergone an objective assessment of posture or spinal alignment. Identifying structural stressors provides valuable information that may help explain persistent symptoms and guide individualized care.
2. Support the Demands Placed on Your Body
   Adequate hydration, appropriate electrolyte intake, correction of nutritional deficiencies, and personalized nutritional guidance help provide the biological resources required to support connective tissue, muscular endurance, and recovery.
3. Build Stability Before Strength
   For individuals with connective tissue disorders, improving stability is often more important than simply increasing strength. We prescribe and encourage progressive rehabilitation, breathing retraining, postural exercises, and carefully supervised conditioning to help improve movement efficiency while reducing unnecessary mechanical stress – especially when performed using whole body vibration therapy.

The Bottom Line

In more than fifteen years of caring for patients with connective tissue disorders, one observation has remained remarkably consistent.

Many individuals have spent years attempting to manage their symptoms without ever having their structural health objectively evaluated.

Although the structural component of these conditions alone does not explain every aspect of hEDS or POTS, we believe it represents one of the most important and overlooked variables influencing how efficiently the body functions and why results occur as structure improves.

Our clinical philosophy is founded upon a simple principle:

Health is the product of structural integrity, neurological efficiency, biochemical and nutritional sufficiency, and adaptive physiology.
When one system begins to deteriorate, the others compensate-until they no longer can.

Lasting improvement is therefore less about chasing individual symptoms and more about restoring the body’s ability to function as an integrated whole.
If you’re living with Ehlers-Danlos Syndrome or POTS, you’ve likely been told to simply manage your condition. While no single treatment provides every answer, we believe many patients have never had their structure objectively evaluated as part of the conversation. If posture, biomechanics, nutrition, and nervous system function are truly interconnected, then understanding your own structural health may become one of the most important steps toward improving your function and reclaiming your quality of life.
