Validation & Orientation: What is Ehlers-Danlos Syndrome?

Last updated:

Ehlers-Danlos Syndrome (EDS) is a group of 13 hereditary connective tissue disorders caused by defective collagen. It is a multisystemic condition that affects joints, skin, and organs, causing a wide range of real, biological symptoms that require proactive management and specialized care.

Key Takeaways

  • • EDS is a hereditary connective tissue disorder caused by genetic defects in collagen production.
  • • There are 13 distinct subtypes of EDS, with Hypermobile EDS (hEDS) being the most common.
  • • Symptoms are multisystemic and can affect joints, skin, digestion, and autonomic functions like heart rate.
  • • Obtaining an accurate EDS diagnosis often takes 10 to 22 years due to its varied and widely misunderstood symptoms.
  • • While there is no cure, EDS can be proactively managed with specialized physical therapy and lifestyle adjustments.

If you have just received a diagnosis of Ehlers-Danlos Syndrome (EDS), you may be feeling a powerful wave of relief followed by a flood of new questions. For many, this diagnosis marks the end of a “diagnostic odyssey”—a long, frustrating journey through the medical system that lasts an average of 10 to 22 years [1][2][3]. During this time, it is common to have been told your symptoms were “just anxiety,” “all in your head,” or to have received 10 or more incorrect diagnoses [3][4]. Your symptoms are real, they have a biological cause, and you finally have a name for them.

What is EDS?

Ehlers-Danlos Syndrome is not just “being double-jointed.” It is a group of hereditary disorders that affect connective tissue, which is the “glue” that holds your body together [5]. Connective tissue is found everywhere: in your skin, joints, blood vessels, and internal organs [6].

The core issue in EDS is a defect in collagen or the extracellular matrix (ECM) [7]. Collagen is a protein that provides strength and structure to your tissues. In EDS, genetic mutations cause the body to produce collagen that is either insufficient or shaped incorrectly [7][8]. Think of it like building a house with rubber bands instead of steel bolts; the structure becomes too flexible and fragile [9].

Understanding the Subtypes

There are currently 13 distinct subtypes of EDS recognized by international classifications [10]. While each type has its own specific genetic “blueprint,” they all share the common theme of connective tissue fragility [11]. To learn more about the 6 most common subtypes, see The 6 Key Subtypes of EDS.

  1. Hypermobile EDS (hEDS): The most common type [12]. Interestingly, it is the only type where the specific gene mutation has not yet been identified, so diagnosis is based on a clinical checklist. For details, see Diagnosis and the 2017 hEDS Criteria [13][14].
  2. Classical EDS (cEDS): Known for extremely stretchy skin and fragile tissues that scar easily [15].
  3. Vascular EDS (vEDS): A rare but serious type that affects the blood vessels and internal organs [16].
  4. Other Types: The remaining 10 types (such as Kyphoscoliotic or Arthrochalasia) are very rare and often involve specific symptoms like severe spine curvature or eye issues [10][17].

Three Stabilizing Facts

As you begin this new chapter, keep these three facts close:

  • It is Multisystemic: Because connective tissue is everywhere, your symptoms are often “strange” and varied [18]. It is normal for EDS to affect your digestion, your heart rate (such as POTS or racing heart), and your energy levels, not just your joints [19][20]. See Symptoms & Multisystem Involvement in EDS for more information. You aren’t “falling apart”; you have one condition that expresses itself in many ways [21].
  • Management is a Marathon, Not a Sprint: There is currently no “cure” that fixes the collagen itself, but there are many ways to manage the symptoms and protect your body [22][2]. The goal is to move from “reacting” to injuries toward “proactive” management through specialized physical therapy and lifestyle adjustments [23][24]. See Standard of Care & Daily Management.
  • You are the Expert on Your Body: Because EDS is often misunderstood by general doctors, you will likely become a key member of your own care team [4]. Your lived experience of your symptoms is the most valuable data your doctors have [25]. Learn how to build your team in Building Your EDS Care Team & Specialist Referrals.

The Emotional Transition

Receiving a diagnosis for a chronic, incurable condition is a major life event. You may feel a “complex emotional transition” [22]. It is normal to feel grief for the years lost to the diagnostic odyssey, or anxiety about the future [22][26]. Validation is a powerful medicine; knowing that your pain has a physical, genetic basis is the first step toward building a life that works with your body, rather than against it [21][12].

Frequently Asked Questions

What causes Ehlers-Danlos Syndrome?
EDS is caused by genetic mutations that affect your body's collagen or extracellular matrix. This results in collagen that is either insufficient or shaped incorrectly, making your connective tissues overly flexible and fragile.
How many subtypes of Ehlers-Danlos Syndrome are there?
There are currently 13 recognized subtypes of EDS. Hypermobile EDS (hEDS) is the most common, while others like Classical EDS and Vascular EDS have different specific genetic markers and physical symptoms.
Why does EDS affect so many different parts of my body?
Because EDS is a connective tissue disorder, and connective tissue is the 'glue' found throughout your entire body. This multisystemic nature means it can affect your joints, skin, blood vessels, digestion, and even your heart rate.
Is there a cure for Ehlers-Danlos Syndrome?
There is currently no cure that fixes the underlying collagen defect in EDS. However, symptoms can be proactively managed through specialized physical therapy, lifestyle adjustments, and building a supportive care team.
How do I know which EDS subtype I have?
Your subtype is determined by a doctor using specific clinical diagnostic criteria or genetic testing. While most types have an identifiable genetic marker, hypermobile EDS is currently diagnosed solely using a clinical checklist.

Questions for Your Doctor

  • • Which of the 13 subtypes of EDS do I have, and was this determined by clinical criteria or genetic testing?
  • • Based on my diagnosis, what specific screening should I have for common 'comorbid' conditions like POTS or MCAS?
  • • Can you recommend a physical therapist who has specific experience working with hypermobile patients?
  • • What are the specific 'red flag' symptoms I should look for that would require immediate medical attention for my subtype?
  • • How does this diagnosis change the way we manage my existing symptoms, such as chronic pain or fatigue?

Questions for You

  • • What emotions am I feeling now that I have a name for my symptoms? Relief? Grief? A mix of both?
  • • What are the top three symptoms that impact my daily life the most right now?
  • • Looking back, what were the early signs or 'clues' from my childhood or early adulthood that make more sense now with this diagnosis?
  • • What activities make me feel strong and safe, and which ones consistently cause me pain or subluxations?
