What is Ehlers–Danlos Syndrome (EDS)?

Ehlers–Danlos syndrome (EDS) is a group of connective tissue conditions that affect the body’s collagen, the structural protein that provides strength and flexibility to tissues such as ligaments, skin, and blood vessels.

Because connective tissue is present throughout the body, EDS can affect multiple systems and may present with symptoms such as joint hypermobility, recurrent injuries, chronic pain, fatigue, digestive issues, and autonomic symptoms.

Many people living with EDS experience long diagnostic journeys because symptoms often appear across different body systems. As a result, patients may present to a range of healthcare practitioners before a connective tissue disorder is recognised.

For clinicians in Traditional Chinese Medicine (TCM), patients with EDS often present with complex, chronic symptom constellations rather than a clearly identifiable biomedical diagnosis. Common presentations may include recurrent musculoskeletal injuries, joint instability, fatigue, dysautonomia (autonomic nervous system dysfunction), headaches, and digestive disturbances.

Awareness of this underlying connective tissue disorder is clinically relevant for TCM practitioners, as it can help contextualise persistent symptom patterns, inform treatment strategy, and guide appropriate referral within an integrative care framework.

Note: Many people have flexible joints without having EDS. Joint hypermobility exists on a spectrum and may occur in otherwise healthy individuals.

When hypermobility is associated with chronic pain, recurrent injuries, or multisystem symptoms, further medical assessment may be appropriate.

Clinical Overview

EDS encompasses 13 currently recognised subtypes, most of which are associated with identifiable genetic mutations affecting collagen or other components of the extracellular matrix. These structural proteins play a critical role in maintaining the integrity and resilience of connective tissues throughout the body.

Pathophysiology

The underlying pathology involves abnormalities in the synthesis, structure, or organisation of collagen. As collagen is widely distributed in connective tissues, defects in its formation can affect multiple anatomical systems. Consequently, EDS is often regarded as a multisystem connective tissue disorder.

Structures commonly affected include:

• ligaments and tendons
• skin
• vascular tissues
• fascia
• gastrointestinal connective tissues
• elements involved in autonomic nervous system regulation

The degree of tissue fragility and systemic involvement varies between subtypes and between individuals.

Key Clinical Features

Clinical presentation can vary significantly depending on the EDS subtype and the individual patient. However, several characteristic features are commonly observed.

Musculoskeletal Features

• Generalised joint hypermobility
• Recurrent joint subluxations or dislocations
• Chronic musculoskeletal pain
• Joint instability and frequent sprains

Cutaneous and Connective Tissue Features

• Soft, hyperextensible, or fragile skin
• Easy bruising
• Delayed or impaired wound healing

Systemic Manifestations

In addition to musculoskeletal involvement, many patients experience broader systemic symptoms, which may include:

• Fatigue and reduced exercise tolerance
• Gastrointestinal dysfunction (e.g., bloating, reflux, dysmotility)
• Headaches or migraines
• Dysautonomia, including symptoms such as dizziness or orthostatic intolerance
• Sleep disturbances
• Impaired proprioception and coordination

For clinicians, the presence of persistent joint instability combined with multisystem symptomsmay raise suspicion of an underlying connective tissue disorder such as EDS. Recognition of these patterns can be particularly important in patients presenting with chronic pain, recurrent injuries, or longstanding functional complaints.

How common is EDS?

EDS has traditionally been considered a rare disorder. However, growing clinical awareness and improved diagnostic criteria suggest that certain forms of EDS may be more common than previously recognised.

Current estimates indicate that the combined prevalence of all EDS subtypes is approximately 1 in 5,000 individuals. Among these, hypermobile Ehlers–Danlos syndrome (hEDS) is believed to be the most prevalent subtype.

The true prevalence of hEDS remains uncertain and is likely significantly underdiagnosed. Many patients experience prolonged diagnostic delays, sometimes spanning several years.

In clinical practice, individuals with EDS are frequently misdiagnosed or labelled with other conditions due to overlapping symptom profiles. These may include:

• fibromyalgia
• chronic fatigue syndrome
• hypermobility spectrum disorders
• autoimmune or inflammatory conditions

Greater awareness of connective tissue disorders among healthcare practitioners may help improve earlier recognition and referral for appropriate evaluation.

Clinical Recognition and Referral Considerations

The formal diagnosis of EDS is typically made by medical specialists, most commonly rheumatologists or clinical geneticists. However, practitioners of Chinese medicine may be among the first clinicians to encounter patients presenting with symptoms suggestive of underlying connective tissue disorders.

Recognition of characteristic clinical patterns is therefore important, as it may support appropriate referral for further biomedical evaluation while enabling practitioners to provide supportive care within an integrative treatment framework.

Patients with EDS often present with a history that includes:

• Generalised joint hypermobility
• Recurrent sprains, joint instability, or subluxations
• Chronic musculoskeletal pain
• Easy bruising
• Fatigue or reduced exercise tolerance
• Gastrointestinal complaints
• Autonomic symptoms, such as dizziness, palpitations, or rapid heart rate when standing

In biomedical settings, joint hypermobility is commonly assessed using the Beighton score (screening tool for hypermobility), a simple screening tool that evaluates joint flexibility across several anatomical sites.

Among the recognised subtypes, hypermobile Ehlers–Danlos syndrome (hEDS) is the most prevalent. Unlike several other forms of EDS, hEDS currently has no confirmed genetic marker and is diagnosed clinically according to the 2017 International Classification of EDS criteria.

For Chinese medicine practitioners, awareness of these clinical features may help identify patients who could benefit from further medical assessment. At the same time, supportive treatment addressing pain, fatigue, and functional impairment can be provided within an integrative care model.

Biomedical Management

There is currently no curative treatment for EDS. Management is typically multidisciplinary, focusing on functional stabilisation and symptom control.

Core strategies include:

• Physiotherapy focusing on muscle strengthening and joint stabilisation
• Pain management strategies, including pharmacological and multidisciplinary approaches
• Lifestyle modification and low-impact exercise
• Monitoring for complications such as cardiovascular involvement in vascular EDS

Individuals who suspect they may have EDS should seek medical evaluation. Diagnosis is typically made by rheumatologists or genetic specialists. However, Chinese medicine may play a supportive role within an integrative care approach.

Traditional Chinese Medicine Management

Within Traditional Chinese Medicine (TCM), treatment is guided primarily by pattern differentiation (bian zheng)rather than by disease classification. While EDS is a well-defined biomedical diagnosis associated with connective tissue abnormalities, TCM practitioners approach management by identifying underlying patterns of functional imbalance.

In TCM, treatment focuses on the individual pattern of imbalance rather than the biomedical diagnosis alone. In practice, this involves addressing both the constitutional tendencies that may underlie connective tissue weakness and the current symptom presentation.

Patients with EDS frequently present with complex, chronic symptom constellations affecting multiple physiological systems, including musculoskeletal instability, fatigue, digestive disturbance, and autonomic dysregulation. Consequently, management often requires a longitudinal and multi-modal approach.

Treatment Principles

Common therapeutic principles may include:

• Nourishing Liver Blood to support tendons and connective tissues
• Tonifying Kidney Essence to strengthen constitutional integrity and skeletal structures
• Strengthening Spleen Qi to address fatigue, digestive weakness, and systemic depletion
• Invigorating Blood and regulating Qi to alleviate chronic pain and improve circulation
• Calming internal wind where instability, tremor, or spasmodic symptoms are present

Common TCM Pattern Considerations

Although EDS is not described as a specific disease entity in classical Chinese medicine literature, several patterns may be clinically relevant.

Kidney Essence Deficiency (Shen Jing Xu)

From a classical perspective, the Kidneys govern the bones and contribute to constitutional strength and structural integrity. Ligamentous laxity, skeletal instability, and chronic fatigue may reflect an underlying deficiency of Kidney Essence.

Liver Blood Deficiency (Gan Xue Xu)

The Liver nourishes tendons and sinews. Insufficiency may manifest as reduced tendon resilience, muscle fatigue, spasms, or impaired recovery from musculoskeletal injury.

Spleen Qi Deficiency (Pi Qi Xu)

Digestive dysfunction, fatigue, and reduced tissue nourishment are frequently associated with Spleen Qi deficiency.

Blood Stasis (Xue Yu)

Chronic pain patterns and recurrent injury may lead to secondary blood stasis, contributing to persistent musculoskeletal discomfort and impaired tissue repair.

Treatment modalities

Acupuncture

Acupuncture may be used to regulate channel function, reduce pain, support neuromuscular coordination, and improve local circulation to affected tissues. Treatment may also support autonomic nervous system regulation and contribute to improved functional stability.

Chinese Herbal Medicine

Herbal prescriptions are typically individualised and adjusted according to the patient’s presentation. In individuals with longstanding constitutional weakness, formulas that nourish Blood, support Kidney function, and strengthen connective tissues may be considered.

In some cases, formulas derived from classical traditions, such as the Jin Gui Yao Lue or Shang Han Lun, may be adapted based on the presenting pattern.

Given the systemic and complex nature of EDS, patients often benefit from integrative care involving collaboration with biomedical practitioners, including physiotherapists and medical specialists experienced in connective tissue disorders.

Other Clinical Considerations for TCM Practitioners

Patients with EDS frequently present with longstanding, multisystem symptom patterns rather than a clearly defined biomedical diagnosis. In Chinese medicine clinics, they may present with complaints such as chronic joint pain, recurrent musculoskeletal injuries, fatigue, digestive dysfunction, headaches, and sleep disturbances.

Because connective tissue fragility and joint instability are characteristic features of EDS, practitioners should be mindful that treatment strategies that focus solely on increasing mobility may not always be appropriate. Instead, emphasis may need to be placed on supporting functional stability, improving tissue resilience, and addressing underlying constitutional patterns.

Careful treatment planning, gradual progression of therapy, and close attention to patient response are often important in managing individuals with hypermobility disorders.

Integrative Clinical Care

Given the multisystem nature of EDS, patients often benefit from an integrative and multidisciplinary approach to care.

Adjunctive strategies may include dietary therapy, gentle movement practices (Tai Chi or Qigong), and lifestyle regulation, particularly in patients experiencing fatigue, digestive disturbance, or autonomic dysregulation.

Collaboration between healthcare providers can play an important role in supporting long-term patient outcomes. TCM practitioners may work alongside physiotherapists, medical practitioners, and other allied health professionals experienced in connective tissue disorders.

A comprehensive management approach may include:

• Physiotherapy focusing on joint stabilisation and proprioceptive training
• Gentle strength and stability training to support musculoskeletal function
• Pain management strategies
• Nutritional and lifestyle support
• Acupuncture and Chinese herbal medicine

Conclusion

Although there is currently no cure for EDS, many individuals benefit from supportive and integrative management strategies. With appropriate diagnosis, careful physical rehabilitation, and supportive therapies such as acupuncture and Chinese herbal medicine, it is often possible to improve symptom management and functional stability.

Greater awareness of connective tissue disorders among healthcare practitioners can help reduce diagnostic delays and support more coordinated, patient-centred care.
