Hypermobile Ehlers-Danlos Syndrome: Symptoms, Diagnosis, Treatment
If you’ve ever been called “double-jointed” or found your body bending in ways that seemed to amaze friends, the reality behind that flexibility might be less party trick and more medical condition. Hypermobile Ehlers-Danlos syndrome (hEDS) is the most common form of a group of connective tissue disorders, and researchers estimate it affects a substantial portion of the population—though pinning down exact numbers remains elusive. Understanding the signs, how diagnosis works, and what management looks like can make a real difference for the estimated millions living with this condition. This guide breaks down what hEDS actually is, how doctors identify it, and what patients can expect along the way.

What are four symptoms of Ehlers-Danlos syndrome?
The symptoms that define Ehlers-Danlos syndromes span multiple body systems, but four stand out as particularly characteristic of the hypermobile type. Joint hypermobility typically shows up as an increased range of motion beyond what most people can achieve—think elbows or knees that bend further than they should. Skin changes present as softness and a velvety texture that feels notably different from typical skin, along with a tendency to bruise easily. Chronic pain, particularly in muscles and joints, often becomes a daily reality for those affected. These four manifestations together paint a picture that clinicians look for during assessment.
Joint hypermobility
Joint hypermobility is the defining feature of hEDS, and healthcare providers use specific tools to measure it. The Beighton score is the most widely recognized screening method—a set of five maneuvers that test flexibility at the thumbs, pinky fingers, elbows, knees, and spine. A score of 6 or higher for pre-pubertal children and adolescents, 5 or higher for those up to age 50, or 4 or higher for adults over 50 suggests significant hypermobility. Beyond the clinical score, people often notice their joints feel loose, click during movement, or dislocate more easily than others’ would.
Skin changes
The skin in hEDS typically feels soft and velvety to the touch, with a texture that many describe as unusual. Unlike some other EDS types that feature extreme skin fragility and delayed wound healing, hEDS skin is hyperextensible—meaning it can be stretched further than normal and still return to its original position. Bruising occurs more readily, and some individuals notice visible veins or a tendency toward hernias and varicose veins. Importantly, the diagnostic criteria specifically exclude unusual skin fragility, since that feature would point toward a different EDS subtype rather than hEDS.
Pain and instability
Musculoskeletal pain in two or more limbs that recurs daily for at least three months represents one formal criterion for hEDS diagnosis. This pain often stems from joint instability—the connective tissues holding joints in place don’t function as they should, leading to micro-injuries and strain on surrounding muscles. Recurrent joint dislocations or clear joint instability that happens without significant trauma also factors into the diagnostic picture. The NHS notes that people with hEDS frequently experience dizziness and increased heart rate upon standing, reflecting autonomic involvement that often accompanies the condition.
Other signs
Beyond joints and skin, hEDS can affect multiple body systems in ways that might not immediately seem connected. Approximately 70% of hEDS patients self-report having or being diagnosed with fibromyalgia, highlighting how commonly chronic pain conditions overlap. Internal organ involvement may include mitral valve prolapse, organ prolapse, and bladder control issues. Dental features such as crowding and high or narrow palate appear more frequently in hEDS populations. Brain fog, headaches, and significant fatigue round out the multisystemic picture that defines this condition.
What does hypermobile Ehlers-Danlos syndrome do?
Hypermobile Ehlers-Danlos syndrome is a heritable connective tissue disorder, meaning it stems from genetic factors passed down within families and affects the body’s connective tissue throughout life. The disorder causes generalized joint hypermobility—which sounds like a minor party trick but translates to real functional challenges when joints move beyond their proper range. Joint instability and chronic pain become daily companions for many people with hEDS, affecting everything from walking to sleeping. The condition is managed as lifelong because no curative treatments currently exist, making symptom management and injury prevention the central goals of care.
Joint effects
The joints bear the brunt of hEDS because connective tissue—the proteins that provide structure and support throughout the body—doesn’t hold joints in place as firmly as it should. This leads to a cascade of potential problems: joints that subluxate (partially dislocate), fully dislocate, click or pop during movement, and feel chronically unstable. People with hEDS often describe a constant awareness of their joints “giving out” or feeling unreliable during everyday activities. This instability can occur in any joint but commonly affects knees, shoulders, fingers, and the jaw.
Tissue impacts
Connective tissue exists throughout the body, which explains why hEDS effects extend beyond joints. Cardiovascular manifestations include mitral valve prolapse and, less commonly, aortic root dilatation. The Hypermobility Syndromes Association notes that hernias and varicose veins may appear as signs of underlying tissue fragility. Gastrointestinal issues and bladder control problems reflect connective tissue involvement in those organ systems. The arm span-to-height ratio exceeding 1.05 appears more frequently in hEDS populations, suggesting broader skeletal impacts from the underlying tissue difference.
Daily challenges
Living with hEDS means navigating daily challenges that others might not consider. Simple activities like standing for extended periods, carrying heavy objects, or participating in exercise require careful management to avoid injury. The fatigue that accompanies hEDS often exceeds what would be expected from physical activity alone, pointing to broader systemic effects. A U.K. patient survey found the median time to diagnosis was 10 years—a delay that means many people spend a decade not understanding why their body functions differently than they expect. Early multidisciplinary treatment including physical, occupational, and cognitive behavior therapy can help optimize outcomes, though comprehensive care remains challenging to access.
What are 7 signs you have hypermobility?
Recognizing hypermobility often starts with personal observation before any clinical testing. The Beighton score provides a validated five-part questionnaire alongside the physical examination to assess joint mobility systematically. Seven key signs frequently appear in those with significant hypermobility: thumbs that can touch the forearm, pinky fingers that bend backward past 90 degrees, elbows that hyperextend, knees that bend backward, spine flexibility allowing palms to touch the floor, joints that click regularly, and a history of dislocations or near-dislocations. These signs individually don’t confirm hEDS but together paint a clearer picture when combined with other clinical features.
Joint tests
The Beighton score remains the gold standard for assessing joint hypermobility in a clinical setting. Five maneuvers form the basis: forward trunk flexion with knees straight (palms flat on floor), left and right knee hyperextension past 10 degrees, left and right elbow hyperextension past 10 degrees, left and right thumb flexion to touch the forearm, and left and right pinky hyperextension past 90 degrees. Healthcare providers trained in using this scoring system can quickly assess whether someone meets the threshold for significant hypermobility, though the score alone doesn’t diagnose hEDS—it serves as one piece of a larger diagnostic puzzle.
Common indicators
Beyond formal testing, several everyday observations may indicate hypermobility worth discussing with a healthcare provider. Frequent joint clicking or popping during normal movement often catches attention. A history of dislocating joints or having them “go out” with minimal provocation represents a more serious indicator. Soft, velvety skin that bruises easily frequently accompanies joint hypermobility. Chronic pain that seems disproportionate to any injury or activity level warrants attention. Family history matters significantly—the diagnostic criteria recognize positive family history as a relevant feature, meaning if first-degree relatives have similarly flexible joints or related conditions, that information supports the diagnostic picture.
Self-assessment
Self-assessment can provide useful information to bring to a healthcare appointment, though it shouldn’t replace professional evaluation. The five-part questionnaire validated alongside the Beighton score helps capture hypermobility history that might not be present during a single examination. Questions address whether you’ve ever been called “double-jointed,” whether you can bend and touch your toes with your knees straight, and whether you’ve dislocated joints. Importantly, self-assessment should focus on patterns over time rather than single moments—a flexible joint once doesn’t indicate chronic hypermobility, while consistent patterns across multiple joints and body regions warrant professional attention.
What are hypermobile Ehlers-Danlos syndrome diagnostic criteria?
The diagnostic criteria for hEDS were updated in 2017 by an international consortium with the goal of improving diagnostic specificity. For hypermobile Ehlers-Danlos syndrome, the most common form, there is no genetic testing available—diagnosis relies entirely on clinical features, physical examination, and medical history rather than laboratory or genetic confirmation. The 2017 criteria require three main components: generalized joint hypermobility (assessed via Beighton score), additional clinical features spanning musculoskeletal involvement and systemic manifestations, and the absence of unusual skin fragility which would suggest another EDS type. Critically, these criteria also require the exclusion of other conditions that could explain the presentation.
Clinical features
The 2017 criteria enumerate specific clinical features that must be present to support an hEDS diagnosis. Beyond generalized joint hypermobility, individuals need two or more of the following: musculoskeletal pain in two or more limbs recurring daily for at least three months, recurrent joint dislocations or frank joint instability without trauma, or systemic manifestations including skin features, organ involvement, or skeletal findings. Systemic features recognized by the criteria include mitral valve prolapse, aortic root dilatation, hernias, organ prolapse, dental crowding with high/narrow palate, and arm span-to-height ratio of 1.05 or greater. Family history also factors in—a positive history with first-degree relatives independently meeting current criteria supports the diagnosis.
Scoring systems
The Beighton scoring system provides the quantitative backbone for assessing joint hypermobility, but the full diagnostic picture requires more. The five-part questionnaire captures historical hypermobility information that might not be present during examination, addressing the question of whether someone was “always” flexible. Age-adjusted cutoffs account for the fact that joint flexibility typically decreases with age—a 25-year-old meeting different thresholds than a 60-year-old. The criteria explicitly state the absence of unusual skin fragility, distinguishing hEDS from vascular EDS and other types where skin tearing and delayed wound healing represent serious concerns. This boundary helps direct clinicians toward the correct diagnosis subtype.
Tests involved
Unlike many genetic conditions, hEDS diagnosis doesn’t involve blood tests or genetic sequencing. The diagnostic process relies on physical examination, detailed medical history, and clinical judgment. Echocardiography may be ordered if mitral valve prolapse or aortic root involvement is suspected based on other criteria findings. Healthcare providers diagnose EDS with a physical exam and by discussing medical history—no special imaging or laboratory testing confirms hEDS specifically. The criteria have faced criticism from some quarters for being too stringent and potentially failing to capture the full spectrum of multisystemic involvement that patients experience, suggesting the diagnostic framework may continue evolving as understanding improves.
What is hypermobile Ehlers-Danlos syndrome treatment?
Treatment for hEDS focuses on managing symptoms and preventing joint injury because no cure exists for this lifelong condition. Exercises to strengthen muscles and stabilize joints represent the primary treatment approach, according to the Mayo Clinic and other major medical institutions. Physical therapy forms the cornerstone, with therapists working to build supporting musculature that can compensate for ligamentous laxity. Pain management typically begins with over-the-counter options like acetaminophen, ibuprofen, and naproxen sodium, though stronger medications are reserved only for acute injury situations rather than chronic management. There is no cure for EDS, but treatment is available to help manage symptoms and complications.
Management strategies
The central goals of therapy for hEDS are managing symptoms, preventing joint injury, and teaching patients about their condition. Patient education, physical and occupational therapy, psychological support, and self-management represent the mainstays of management. A study of 76 patients using 2017 diagnostic criteria found that occupational therapy including splints and bracing was reported as beneficial by 70% of participants, while surgery was beneficial for 59%. Joint protection techniques teach patients how to move and position their bodies to minimize stress on vulnerable joints. Bracing and supportive devices help stabilize joints during activities that might otherwise cause injury.
Pain relief
Over-the-counter pain relievers such as acetaminophen, ibuprofen, and naproxen sodium serve as the mainstay of pain treatment for most hEDS patients. Healthcare providers generally limit stronger pain medications to acute injury situations rather than prescribing them chronically, reflecting concerns about dependency and the limited evidence for long-term benefit in this population. Heat therapy, avoidance of potentially dangerous activities, and complementary approaches like gentle massage may provide additional relief. Some patients report benefits from anti-inflammatory approaches, though responses vary significantly between individuals.
Supportive care
Supportive care extends beyond medication to encompass the broader aspects of living with a chronic condition. Wearing sunscreen and using mild soaps protects skin that bruises more easily and may heal differently than typical skin. Blood pressure management may be necessary in some cases because blood vessels are more fragile in certain EDS types. Wearing braces for extra joint support represents a common treatment approach that helps people maintain function. Psychological support helps patients cope with the chronic nature of the condition and the adjustment to activity modifications that may be necessary throughout life.

The practical reality for anyone suspecting they might have hEDS involves navigating a healthcare system that often takes years to reach the correct diagnosis. Physical therapy to strengthen muscles around joints remains the most evidence-supported intervention available, while pain management relies heavily on over-the-counter options and activity modification. The diagnostic criteria require clinical expertise and careful assessment, making specialist evaluation important for anyone meeting the threshold for concern. What the research makes clear is that early intervention and patient education improve outcomes—understanding how to protect vulnerable joints prevents the cascade of injuries that can accompany this lifelong condition.

Frequently asked questions
Do people with EDS have high metabolism?
No established scientific evidence confirms that people with hEDS have inherently high metabolism. While some online communities discuss metabolic differences, research has not validated specific metabolic patterns in hEDS populations. People with EDS may experience weight changes related to activity limitations, medication side effects, or other factors, but no direct metabolic connection has been demonstrated through clinical research.
Can EDS cause weight gain or weight loss?
EDS itself doesn’t directly cause weight changes, but secondary factors may affect weight. Activity limitations from joint pain and instability can reduce caloric expenditure. Some medications used for pain management may influence weight. Conversely, severe symptoms might reduce appetite. Any significant weight changes in someone with EDS likely reflect these secondary factors rather than the condition itself.
Is EDS a type of autism?
No, EDS is not a type of autism. These are separate conditions with different underlying mechanisms. However, research has identified higher rates of co-occurrence between EDS and autism spectrum conditions than would be expected by chance. Both conditions involve genetic components and affect multiple body systems. The overlap suggests shared biological pathways may exist, but having one condition doesn’t mean someone has the other.
Is hypermobility a form of autism?
Hypermobility and autism are separate conditions, though they may co-occur in some individuals. Joint hypermobility itself is simply a physical trait—the Beighton score measures it quantitatively. When hypermobility occurs as part of hEDS or hypermobility spectrum disorders, it represents a connective tissue difference. The elevated co-occurrence with autism mentioned in some research suggests possible shared genetic or developmental factors rather than one condition being a form of the other.
Which parent passes down EDS?
EDS can be inherited from either parent, and the inheritance pattern varies by EDS type. For hEDS specifically, the inheritance pattern remains incompletely understood because no single causative gene has been identified. Family history is a diagnostic criterion, and first-degree relatives meeting current criteria support the diagnosis. Some families show clear autosomal dominant patterns with affected individuals in multiple generations, though this isn’t universal.
At what age does EDS usually start?
Symptoms of EDS typically begin in childhood or adolescence, though the age of diagnosis often comes much later. Joint hypermobility often becomes noticeable during growth periods when children become more physically active. Chronic pain, subluxations, and other features may first appear or worsen during adolescent growth spurts. Many adults receive diagnoses only after years of unexplained symptoms, with the median time to diagnosis in U.K. surveys reaching 10 years.
What is hypermobile Ehlers-Danlos syndrome skin like?
Skin in hEDS typically feels soft and velvety, with a texture notably different from typical skin. The skin is hyperextensible—it can be stretched and will return to normal rather than remaining stretched. Bruising occurs more easily, and some individuals notice prominent veins. Importantly, hEDS skin does not show unusual fragility with poor wound healing, which distinguishes it from other EDS types where skin fragility represents a serious clinical concern.
What is hypermobile Ehlers-Danlos syndrome ICD-10 code?
The ICD-10 code for hypermobility syndrome is M35.7, though this may vary by specific classification system used. For hEDS specifically, coding practices may differ between healthcare systems. Patients discussing diagnosis with providers should confirm the appropriate code for their medical records. hEDS falls under the broader category of connective tissue disorders in most classification systems.
