Understanding the Link Between Ehlers-Danlos Syndrome & Postural Orthostatic Tachycardia Syndrome

Ehlers-Danlos Syndrome (EDS) and Postural Orthostatic Tachycardia Syndrome (POTS) are two chronic conditions that frequently overlap, affecting connective tissues and autonomic nervous system function. Many individuals diagnosed with EDS experience symptoms associated with POTS, and vice versa. Since both conditions fall under dysautonomia, they disrupt the body’s ability to regulate involuntary functions like blood pressure, heart rate, and circulation.

Understanding their connection can help patients and healthcare providers approach symptom management more effectively. Recognizing the shared mechanisms between EDS and POTS is essential for developing targeted treatments that improve quality of life.

Exploring the Relationship Between EDS and POTS

The link between EDS and POTS lies in connective tissue instability and autonomic dysfunction. Many individuals with hypermobile Ehlers-Danlos Syndrome (hEDS) experience difficulty maintaining vascular tone, meaning their blood vessels may not constrict efficiently upon standing. This can result in poor circulation, blood pooling, and excessive heart rate fluctuations, common characteristics of POTS.

Since connective tissues support blood vessels, weakened tissues in EDS can contribute to circulatory dysfunction, increasing the likelihood of orthostatic symptoms. Additionally, nervous system dysregulation in POTS can intensify joint pain, fatigue, and digestive complications—symptoms frequently experienced by those with EDS.

What is Ehlers-Danlos Syndrome (EDS)?

Ehlers-Danlos Syndrome (EDS) is a genetic connective tissue disorder that disrupts collagen production and function, resulting in widespread complications throughout the body. Collagen plays a fundamental role in providing structural support to tissues, organs, joints, and blood vessels. When faulty, it leads to skin elasticity issues, joint instability, and vascular fragility, impacting both mobility and overall health.

Variability Among EDS Subtypes

EDS is a spectrum disorder, meaning its symptoms and severity vary significantly based on the specific subtype. Some forms primarily affect joint flexibility, while others lead to severe vascular complications. Despite these differences, all forms of EDS share common characteristics related to connective tissue fragility, making early identification and management crucial for long-term health.

The Role of Collagen in EDS

Collagen is responsible for reinforcing connective tissue, ensuring that the body’s structures remain stable and resilient. When mutated, collagen fails to properly support tissue integrity, leading to loose joints, soft skin, and increased injury susceptibility. The effects of collagen dysfunction extend beyond mobility issues, often contributing to chronic pain, poor wound healing, and circulatory instability.

Understanding the underlying mechanisms of EDS helps individuals and healthcare providers develop personalized management strategies, focusing on joint protection, physical therapy, and autonomic regulation, especially in cases where EDS is linked to Postural Orthostatic Tachycardia Syndrome (POTS).

EDS and Autonomic Dysfunction

Among the various EDS subtypes, Hypermobile Ehlers-Danlos Syndrome (hEDS) is most frequently associated with autonomic dysfunction. Many individuals with hEDS experience dysautonomia, which impacts the autonomic nervous system’s ability to regulate heart rate, blood pressure, and circulation. This connection explains why POTS (Postural Orthostatic Tachycardia Syndrome) is commonly seen in those with hEDS, often leading to lightheadedness, tachycardia, and exercise intolerance.

Key Symptoms of EDS

Ehlers-Danlos Syndrome (EDS) presents with a diverse range of symptoms, affecting multiple body systems. While the severity varies among individuals, some hallmark features are consistently observed.

Joint Hypermobility

EDS is often characterized by excessive joint flexibility, resulting from weakened connective tissues. This leads to:

Frequent joint dislocations and subluxations, particularly in the shoulders, knees, and fingers.
Chronic instability, making daily movements unpredictable and sometimes painful.
Musculoskeletal pain, as overworked muscles compensate for joint laxity.

Skin Hyperextensibility

Individuals with EDS often experience skin that stretches beyond normal limits, feeling soft or velvety to the touch. Additional concerns include:

Easy bruising, even with minor impacts or pressure.
Delayed wound healing, increasing susceptibility to scars and tissue damage.
Fragile skin, prone to cuts and abrasions due to reduced structural integrity.

Chronic Pain and Fatigue

EDS-related pain is often multifaceted, affecting muscles, joints, and nerves. Many individuals experience:

Widespread musculoskeletal discomfort, often aggravated by repetitive movements.
Chronic fatigue, linked to inefficient energy usage and muscular strain.
Poor proprioception, leading to balance and coordination difficulties.

Poor Wound Healing and Vascular Fragility

Collagen abnormalities in EDS weaken vascular structures, leading to:

Increased bruising susceptibility, even with minor trauma.
Slower healing processes, making wounds more prone to reopening.
Potential bleeding disorders, especially in rarer vascular EDS subtypes.

Effective symptom management requires a proactive approach, including physical therapy, hydration strategies, and specialized interventions to minimize complications and improve daily function.

Understanding the connection between EDS and POTS is crucial for effective symptom management, as both conditions require strategic lifestyle adaptations, hydration, physical therapy, and autonomic regulation to improve quality of life.

What is POTS?

Postural Orthostatic Tachycardia Syndrome (POTS) is a form of dysautonomia that disrupts the autonomic nervous system’s ability to regulate blood circulation. When standing, individuals with POTS experience an excessive increase in heart rate, often 30 beats per minute or more above their baseline, accompanied by symptoms such as dizziness, lightheadedness, and fatigue.

How POTS Affects Circulation

In healthy individuals, the body automatically adjusts blood pressure and heart rate when shifting from sitting to standing, ensuring stable circulation. However, in POTS patients, this regulation fails, leading to blood pooling in the lower extremities and an insufficient return of blood to the brain. This triggers compensatory tachycardia, as the heart works harder to maintain adequate oxygen delivery.

Common Symptoms

Symptoms of POTS vary in intensity and may fluctuate throughout the day. The most common signs include:

Exercise intolerance, where physical exertion worsens symptoms.
Dizziness or lightheadedness when standing, often accompanied by nausea.
Heart palpitations or an abnormally fast heartbeat upon postural changes.
Chronic fatigue, making daily activities more challenging.
Brain fog, affecting concentration and memory.

How POTS Disrupts Circulation

Blood pooling in extremities – Causing sluggish circulation and low blood pressure
Rapid heart rate (tachycardia) upon standing – Leads to dizziness and weakness
Temperature regulation issues – Difficulty adapting to heat or cold
Digestive disturbances – Slowed gastric motility affecting nutrient absorption

Since POTS is frequently linked to autonomic dysfunction in EDS, patients with both conditions often require specialized symptom management strategies to stabilize heart rate, blood pressure, and overall circulatory health.

The EDS and POTS Connection

Research indicates a high prevalence of Postural Orthostatic Tachycardia Syndrome (POTS) among individuals with Ehlers-Danlos Syndrome (EDS), particularly those with Hypermobile EDS (hEDS). Estimates suggest that up to 50% of people diagnosed with hEDS also experience POTS, reinforcing the strong correlation between these conditions.

This overlap is largely due to shared physiological mechanisms, including connective tissue instability, autonomic dysfunction, and vascular tone irregularities. Understanding these connections allows patients and healthcare providers to develop more effective symptom management strategies.

Why Do EDS and POTS Co-Exist?

Several underlying factors explain the frequent coexistence of EDS and POTS. These mechanisms contribute to orthostatic intolerance and circulatory challenges, which are hallmark symptoms of both conditions.

Connective Tissue Weakness

EDS affects collagen and connective tissue integrity, weakening blood vessel tone and elasticity. This results in poor vascular constriction, making it harder for veins to push blood back toward the heart when standing.

Venous Pooling

Due to weakened connective tissue, veins struggle to properly regulate blood flow, leading to blood pooling in the lower extremities. The body compensates by triggering a faster heart rate (tachycardia) to maintain adequate blood pressure and circulation.

Autonomic Nervous System Dysfunction

Both conditions involve irregularities in autonomic nervous system (ANS) function, which disrupts heart rate regulation, blood pressure balance, and vascular tone. This exacerbates orthostatic intolerance, causing dizziness, fatigue, and circulation instability upon standing.

Diagnosis: Identifying EDS and POTS Together

Since POTS and EDS frequently coexist, a comprehensive diagnostic approach is essential for accurate identification and treatment planning. Physicians must evaluate both connective tissue integrity and autonomic function to assess the presence of each condition.

Clinical Evaluation

A detailed patient history is crucial, as physicians look for signs of joint hypermobility and autonomic dysfunction during physical examinations.

Diagnostic Criteria for hEDS

To diagnose Hypermobile EDS, specialists often assess:

Beighton Score – A scoring system measuring joint hypermobility
Family History of hEDS – Genetic predisposition is often considered
Systemic Manifestations – Including skin hyperextensibility, chronic pain, and tissue fragility

Diagnosing POTS

To confirm Postural Orthostatic Tachycardia Syndrome, healthcare providers rely on:

Tilt Table Test – Evaluates blood pressure and heart rate changes when shifting from lying down to standing
Active Stand Test – Observes whether heart rate increases by 30+ bpm in adults or 40+ bpm in adolescents within 10 minutes of standing, without a significant drop in blood pressure

Since both conditions can significantly impact quality of life, early identification and multidisciplinary symptom management are crucial for improving patient outcomes.

Managing EDS and POTS Symptoms Together
