What Kind of Doctor Diagnoses hEDS or HSD? How to Prepare

Both hypermobile Ehlers-Danlos Syndrome (hEDS) and Hypermobility Spectrum Disorders (HSD) are clinical diagnoses. This means there is currently no single blood or genetic test that can confirm them ^[1][2]. Instead, diagnosis relies on a physical examination, a detailed medical history, and the targeted exclusion of other conditions.

It is important to know that hEDS and HSD are closely related. hEDS requires a patient to meet strict clinical criteria, while HSD generally describes symptomatic joint hypermobility that does not meet the strict hEDS criteria ^[3][1]. Both conditions can cause substantial symptoms and require dedicated, symptom-based management.

Because there is no one “universal” specialist for these disorders, your evaluation might be conducted by a primary care clinician, a rheumatologist, a medical geneticist, or a physical medicine and rehabilitation doctor, depending on your symptoms and the resources in your area.

Which Doctor Should I See?

Because hEDS and HSD can affect multiple body systems, different doctors can play a role in your diagnosis and ongoing care:

• Primary Care Clinicians: Your primary care doctor can often initiate the assessment, check your joint flexibility, document your symptoms, and coordinate your overall care and referrals ^[3][4].
• Rheumatologists: These doctors specialize in musculoskeletal and autoimmune diseases. A rheumatologist can help evaluate your joint pain and help distinguish your symptoms from inflammatory arthritis conditions, such as rheumatoid arthritis or psoriatic arthritis ^[5][1].
• Medical Geneticists: You may be referred to a geneticist if your physical exam or family history suggests a different, rarer connective tissue disorder. While typical hEDS and HSD do not currently have a known genetic mutation to test for, a geneticist can help evaluate for other single-gene disorders if warranted ^[2][6].
• Physical Medicine and Rehabilitation (PM&R): Also known as physiatrists, these doctors focus on physical function. They evaluate how hypermobility impacts your movement and coordinate a safe, multidisciplinary physical therapy plan, which is central to managing hEDS and HSD ^[7][8].

What the Doctor Will Look For

During your evaluation, the doctor will review your medical history and conduct a physical exam to see if you meet the specific diagnostic criteria for hEDS or HSD.

• Joint Flexibility: The doctor will likely use the Beighton score, a 9-point physical test measuring generalized joint hypermobility ^[9][10]. Note that this score has limitations: thresholds differ by age (including specific pediatric frameworks for children), flexibility can decline with age or after injury, and the score does not measure pain or instability ^[9]. A high score alone does not confirm hEDS, and a lower score does not rule out symptomatic hypermobility (HSD).
• Joint Instability and Pain: You will be asked about your history of joint subluxations (partial dislocations), full dislocations, frequent sprains, and chronic pain ^[9][11]. Note: Please never force a joint to dislocate or subluxate just to prove your symptoms during an exam or for a photograph.
• Skin and Tissue Features: The doctor will check for features common in hEDS, such as mildly soft or stretchy skin, mild stretch marks, or uncomplicated hernias ^[9][12]. However, if you have severe skin fragility, pronounced hyperextensibility, or highly unusual scarring, this might prompt a referral to genetics to evaluate for other rare connective tissue disorders ^[2].
• Associated Systemic Symptoms: You will likely be asked about issues such as chronic fatigue, dizziness when standing, or gastrointestinal problems ^[13][14]. While common in people with hEDS and HSD, these are associated symptoms rather than formal diagnostic criteria, and they may require separate evaluation and treatment ^[3].
• Family History: hEDS appears to run in families and is presumed to follow an autosomal dominant inheritance pattern ^[3][15]. However, the specific gene has not yet been identified, and many people diagnosed with hEDS or HSD do not have a known family history of the condition.

What to Bring to Your Evaluation

Clinicians conduct a targeted assessment to rule out other likely causes based on your history and exam; you do not need an exhaustive battery of tests before hEDS or HSD can be diagnosed. Bringing the right documentation can make this process much more efficient.

• A Symptom Timeline: Write down when your pain and joint instability started, which joints are most affected, and how these symptoms impact your daily household, work, and social activities ^[16]. It is also helpful to note your main functional goals and how you have responded to physical therapy in the past.
• Prior Medical Records: Bring notes from previous doctors, especially if they show you have been evaluated for other conditions like inflammatory or autoimmune diseases ^[1][3].
• Evidence of Injuries: Bring emergency room discharge summaries, physical therapy notes, or imaging reports (like X-rays or MRIs) that document past dislocations, subluxations, or severe sprains ^[1][11]. Photographs of severe bruising or unusual scars can provide helpful context, but they do not replace a physical exam ^[9].
• Prior Test Results: If you have previously had genetic testing or heart imaging (such as an echocardiogram), bring those reports for context. While these tests are ordered selectively based on specific findings, a normal echocardiogram or negative genetic panel does not rule out hEDS or HSD—they simply help rule out the specific genes or conditions they tested for ^[17][2].
• Family Health History: Come prepared with a list of any blood relatives who have experienced joint dislocations, chronic pain, severe skin fragility, or have been diagnosed with a connective tissue disorder ^[3].
