What Is Ehlers-Danlos Syndrome? Understanding the Genetics, Connective Tissue, and Reality of Living With EDS
Our bodies are extraordinary things. They bend, stretch, move, heal, and carry us through our lives. But what happens when the very tissue responsible for holding us together does not work the way it should?
For those of us living with Ehlers-Danlos Syndrome (EDS), that is not a
hypothetical question... It is our everyday reality.
I was 55 years old when I finally got my diagnosis. I live with hypermobile EDS (hEDS), POTS, and MCAS, and I can tell you firsthand that this condition is complex, painful, frustrating, and so often misunderstood. Part of what helped me make peace with my body was finally understanding what was actually happening inside it.
So today I want to answer a question I hear all the time. What is Ehlers-Danlos Syndrome, where does it come from, and why does it affect so many different parts of the body?
What is Ehlers-Danlos Syndrome?
EDS is so much more than being unusually flexible. It is a group of 13 currently recognized hereditary connective tissue disorders, each with its own characteristics, diagnostic criteria, and genetic considerations. It can affect nearly every part of the body, from our joints and skin to our blood vessels and digestive systems.
To understand EDS, it helps to understand connective tissue. Think of it as the body’s structural framework. It provides support, stability, flexibility, and strength, and it is found in our skin, ligaments, tendons, muscles, joints, blood vessel walls, internal organs, and digestive tract.
One of the most important proteins in connective tissue is collagen. In many types of EDS, genetic changes interfere with how collagen is made, processed, or organized, so tissues may become unusually fragile, stretchy, or unstable.
Imagine building a house with support beams that are not quite as strong as they should be. The house can still stand, but everything around those beams has to work harder to hold it up. For many of us with EDS, that is what everyday life feels like.
Where does EDS come from?
One of the most important things to understand is that EDS is generally genetic. It is not something you developed because you stretched too much, exercised the wrong way, experienced too much stress, or failed to take care of yourself.
Our genes contain the instructions for building proteins, including those that build and maintain connective tissue. When certain genes carry disease-causing variants, those proteins may be altered or produced in insufficient amounts.
Some examples:
COL5A1 and COL5A2 are associated with classical EDS.
COL3A1 is associated with vascular EDS.
COL1A1 and COL1A2 are associated with certain rarer types.
TNXB is associated with classical-like EDS.
There is an important distinction for those of us with hypermobile EDS. The specific genetic cause of hEDS has not yet been identified for most people, and there is currently no validated genetic test that can confirm the diagnosis. Researchers are still working to understand the biology behind it.
Is EDS inherited?
Often, yes. Several types follow an autosomal dominant pattern, meaning one affected parent can pass it on. Others are autosomal recessive, meaning a person generally inherits a variant from both parents. Some cases arise from a brand new genetic variant with no family history at all.
Hypermobile EDS frequently runs in families, even though its exact genetic basis is unresolved. That is why so many people look back and realize generations of relatives had unusually flexible joints, chronic pain, frequent sprains, or unexplained symptoms that were never connected to a single cause. Sometimes the family history is there. It just has not been recognized yet.
The types of EDS
Not all EDS is the same. These conditions share certain connective tissue features, but their symptoms, complications, and severity can differ significantly. The most commonly discussed types are:
Hypermobile EDS (hEDS): The most common form, marked by joint hypermobility, instability, chronic pain, and often fatigue and other multisystem symptoms.
Classical EDS (cEDS): Often involves stretchy, fragile skin, abnormal scarring, and hypermobile joints.
Vascular EDS (vEDS): A rarer and potentially life threatening form involving fragile blood vessels and organs.
The remaining ten types are considerably rarer and can affect the muscles, eyes, heart valves, gums, skeleton, and skin.
Why does EDS affect so many parts of the body?
Connective tissue is everywhere. When it is not functioning the way it should, the effects are rarely limited to one joint or one body system.
Joint instability and chronic pain
When ligaments cannot provide enough stability, joints can move beyond their intended range. That can mean recurring sprains, subluxations, dislocations, and chronic pain. Our muscles work overtime trying to stabilize joints that will not stay put, which contributes to fatigue, tension, and soreness.
On the days my joints and muscles are especially vocal, I reach for my Desert Release Pain Salve or my Pain Ease Gel. Both were made with chronic pain in mind, and having a topical option in my toolkit makes a real difference on the hard days.
Dysautonomia and POTS
Many people with hEDS also experience dysautonomia, which involves dysfunction of the autonomic nervous system. One commonly associated condition is Postural Orthostatic Tachycardia Syndrome (POTS), which can cause a sharp rise in heart rate upon standing, along with dizziness, fatigue, palpitations, and difficulty tolerating being upright. Researchers are still investigating the biological link between POTS and hEDS.
Mast cell sensitivities
Some people with EDS also report allergies, flushing, digestive reactions, and symptoms involving mast cells, which are immune cells involved in allergic and inflammatory responses. Mast Cell Activation Syndrome (MCAS) is often discussed alongside EDS and POTS, but the relationship is still uncertain, and having EDS does not automatically mean someone has MCAS. Symptoms that look like mast cell reactions can have several different causes, so this is one to explore with a knowledgeable provider.
Digestive difficulties
Connective tissue also supports the gastrointestinal tract. People with hEDS may experience bloating, reflux, constipation, abdominal discomfort, and altered bowel function, often involving a mix of motility, sensitivity, and autonomic factors.
Gentle digestive support has been a big part of my own routine, and my Gut Garden Tea was created with exactly this in mind. It is a soothing blend of cistus, spearmint, roasted dandelion root, and lemon balm, designed to be sipped consistently rather than used as a quick fix.
Chronic fatigue and nervous system strain
Imagine spending every day trying to stabilize joints that do not feel secure, managing pain, coping with unpredictable symptoms, and still trying to accomplish ordinary tasks. It is exhausting. Fatigue in EDS can have many contributors, including chronic pain, disrupted sleep, dysautonomia, and associated conditions. And sometimes, even when we do everything right, the fatigue is still there. That is one of the hardest things for people without EDS to understand.
When my nervous system feels like it is running on empty, I reach for my Calm and Steady tea. Lemon balm, chamomile, linden flowers, rose petals, and spearmint make a gentle, comforting cup that signals to the body that it is okay to slow down.
Were we born with EDS, or can it develop later?
EDS is present from birth because the underlying predisposition is genetic. But symptoms may not become obvious until much later. Some people show signs in childhood, while others are not diagnosed until their thirties, forties, fifties, or beyond. I was one of them.
Certain life experiences can make symptoms more noticeable, including puberty and hormonal changes, pregnancy and postpartum changes, injuries or surgery, periods of reduced physical conditioning, and aging. These factors do not create the underlying condition. They can influence how existing connective tissue vulnerabilities show up.
Someone who was considered wonderfully flexible as a child may eventually begin experiencing significant pain, instability, or fatigue. What once seemed like a talent may turn out to have been an early clue.
Why is EDS so often misdiagnosed?
One of the most frustrating parts of EDS is how long it can take to get an accurate diagnosis. People with hEDS often spend years seeing different specialists, each treating a different symptom. One physician addresses the joint pain. Another investigates digestive issues. A cardiologist evaluates dizziness and heart rate. A neurologist looks into migraines. And the possibility that all of it is connected through one systemic condition can go unrecognized for decades.
Hypermobility also exists on a spectrum. Not everyone with flexible joints has EDS, and not everyone with EDS looks visibly hypermobile, especially as they age and joints stiffen.
How is EDS diagnosed?
It depends on the suspected type. For hEDS, clinicians use established clinical criteria, including joint hypermobility, additional connective tissue features or family history, musculoskeletal complications, and the exclusion of other explanations. For the other recognized types, genetic testing can help confirm a diagnosis. Evaluation by specialists in genetics or rheumatology can be helpful.
It is also important to know that someone can have significant, symptomatic hypermobility without meeting the criteria for hEDS. Hypermobility Spectrum Disorders (HSD) are real conditions and deserve appropriate care too.
Can Ehlers-Danlos Syndrome be cured?
Currently, there is no cure for EDS. We cannot replace the underlying genetic instructions or repair every affected tissue.
But that does not mean there is nothing we can do. Managing EDS often involves a combination of medical care, physical rehabilitation, symptom management, and lifestyle adaptations. Strengthening the muscles around vulnerable joints, improving proprioception, protecting unstable joints, and learning to pace activity can all be valuable.
For some people, gentle breathing practices and Yoga Nidra offer opportunities for relaxation, body awareness, and nervous system support. Having trained as a yoga teacher, I believe the difference between flexibility and stability matters enormously. Just because a joint can move farther does not mean it should. For those of us with EDS, movement should prioritize stability, control, and comfort rather than deep stretching or pushing into end ranges.
Herbal medicine can also play a complementary role in supporting things like stress, sleep, and digestion when chosen thoughtfully, with attention to medications and individual sensitivities. But herbs cannot correct the genetic causes of EDS or rebuild collagen, and no herbal treatment reverses the condition. The goal is a thoughtful, individualized approach that supports the whole person.
The emotional reality of living with EDS
There is something else we need to talk about, and that is the emotional weight of living with a chronic, unpredictable condition.
EDS can change how we work, travel, exercise, socialize, and plan our days. Some mornings we wake up feeling relatively functional. Other days, getting out of bed feels like climbing a mountain. Plans change. Energy disappears. Pain takes over. And because so much of EDS is invisible, other people often do not understand why we are struggling.
A diagnosis does not take away the pain or the limitations. But it can give us language for our experience, help us seek more appropriate care, and remind us that our symptoms deserve to be taken seriously.
Why is the zebra the symbol of EDS?
If you have spent any time in the EDS community, you have probably met our beloved zebras.
The symbolism comes from a saying in medical education: when you hear hoofbeats, think horses, not zebras. It encourages doctors to consider common diagnoses before rare ones. But sometimes those hoofbeats really do belong to a zebra.
For people with EDS, the zebra has become a symbol of recognition, resilience, and community. And just as no two zebras have identical stripes, no two people with EDS have exactly the same experience. Some have relatively mild symptoms. Others face significant disability and daily pain. Every experience matters.
Understanding our bodies is an act of compassion
So, what is Ehlers-Danlos Syndrome? It is not simply a flexibility disorder. It is a complex group of genetic connective tissue conditions that influence how our bodies move, function, and respond to the world around us. We are born with the underlying condition, but how it shows up can change throughout our lives.
Science has made real progress, especially with the rarer, genetically defined types, but there is still much to learn about hypermobile EDS. In the meantime, knowledge is powerful. Understanding where EDS comes from helps us make sense of our symptoms, recognize our limits, advocate for appropriate care, and approach our bodies with more kindness.
We may not be able to change our genetics, but we can learn to work with our bodies instead of constantly fighting them. We can seek support. We can build strength where we can. We can honor our need for rest.
If you are living with EDS, POTS, MCAS, or chronic pain and you are looking for support that understands what this is like from the inside, that is what I built Desert Bloom for. I offer one on one Yoga Nidra sessions and herbal consultations, and my Rooted Resilience program is designed specifically for people navigating EDS and other complex chronic conditions, with personalized herbal support, nervous system care, and compassionate guidance.
And please remember this... Living with a complicated body does not diminish the beauty or value of the life within it.
We are zebras. We are resilient. And we deserve to be seen, heard, understood, and supported.
With love, herbs, and a little desert magic,
