Understanding Ehlers-Danlos

A Root Cause Guide to EDS Awareness Month

May is Ehlers-Danlos Syndrome Awareness Month. And if you or someone you love has been living with EDS, you already know that awareness is desperately needed. Because EDS is one of the most misunderstood, misdiagnosed, and underdiagnosed conditions in medicine today.

The average person with EDS waits more than a decade to receive a correct diagnosis. In that time they are often told their pain is psychological, their symptoms are exaggerated, or that their test results are too normal to explain what they are experiencing. They see specialist after specialist. They collect diagnoses that don't quite fit. And they continue to suffer without a framework that actually explains what is happening in their body.This article is an introduction to what EDS actually is, why it affects so many systems simultaneously, and what a root cause perspective can offer people who are navigating life with this complex condition.

What Is Ehlers-Danlos Syndrome?

Ehlers-Danlos Syndrome is a group of heritable connective tissue disorders characterized by defects in the structure, production, or processing of collagen. There are thirteen recognized subtypes, each with its own genetic underpinning and clinical features, ranging from hypermobile EDS (hEDS) to classical EDS, vascular EDS, kyphoscoliotic EDS, and several others.

Collagen is the most abundant protein in the human body. It is the primary structural protein in skin, tendons, ligaments, blood vessels, organ walls, cartilage, bone, and the cornea of the eye. Think of collagen as the scaffolding that holds the body together and gives tissues their strength, elasticity, and integrity.

When collagen is defective, that scaffolding is compromised. And because collagen is everywhere in the body, the consequences are felt everywhere in the body. EDS is not a single-organ condition. It is a systemic condition that touches virtually every tissue and system simultaneously.

This is why EDS is so frequently misunderstood. A person with EDS may present to a cardiologist for dysautonomia, to a gastroenterologist for motility issues, to a rheumatologist for joint pain, to a neurologist for headaches, and to a gynecologist for pelvic floor dysfunction. Each specialist sees their piece of the puzzle. Very few connect them all.

The Many Faces of EDS

Because connective tissue is everywhere, the symptoms of EDS are extraordinarily diverse and vary significantly from person to person even within the same subtype. This variability is one of the reasons EDS is so difficult to recognize and diagnose.

• Joint hypermobility is the hallmark feature of hypermobile EDS, the most common subtype. Joints that move beyond their normal range of motion may seem like a party trick in childhood, but over time they cause chronic joint instability, recurrent dislocations and subluxations (partial dislocations), pain, and early wear on joint surfaces. Simple activities that most people perform without thought can cause significant joint injuries in someone with EDS.

• Chronic pain is one of the most debilitating aspects of EDS and one of the most difficult to manage. The pain in EDS is multifactorial, arising from joint instability, muscle overactivation as the body attempts to compensate for unstable joints, nerve sensitization, and the inflammatory processes that accompany chronic tissue stress.

• Skin manifestations are prominent in several EDS subtypes. Skin may be velvety soft, highly elastic, or fragile. It may bruise easily, heal poorly, or scar in unusual ways. Stretch marks may appear disproportionate to any weight change. Wound healing after surgery can be complicated by the collagen defect.

• Dysautonomia is extremely common in EDS, particularly hEDS, and represents one of the most impactful comorbidities. The autonomic nervous system regulates heart rate, blood pressure, digestion, temperature regulation, and many other involuntary functions. When connective tissue supporting blood vessels is defective, blood can pool in the lower body upon standing, leading to a form of dysautonomia called Postural Orthostatic Tachycardia Syndrome (POTS). Symptoms include dizziness, lightheadedness, rapid heart rate upon standing, brain fog, fatigue, and near-fainting.

• Gastrointestinal issues are reported by the majority of people with EDS and include gastroparesis (delayed gastric emptying), small intestinal bacterial overgrowth (SIBO), irritable bowel syndrome, chronic constipation or diarrhea, and significant food intolerances. Defective connective tissue in the gut wall affects motility, barrier integrity, and the mechanical function of the entire digestive tract.

• Mast Cell Activation Syndrome (MCAS) is now recognized as a frequent companion to EDS, forming what some researchers describe as a triad with EDS and POTS. Mast cells are immune cells that release histamine and other inflammatory mediators. In MCAS, mast cells are inappropriately activated by triggers that should be harmless, leading to a wide range of symptoms including flushing, hives, itching, swelling, gastrointestinal distress, brain fog, and anaphylaxis-like reactions. The collagen matrix around mast cells may play a role in their dysregulation in people with EDS.

• Craniocervical and spinal instability are significant concerns in EDS, as defective ligaments in the neck and spine may allow excessive movement that places pressure on the spinal cord, brainstem, and adjacent nerves. This can contribute to headaches, neck pain, neurological symptoms, and in severe cases, debilitating functional impairment.

• Fatigue in EDS is profound and often underappreciated. It arises from multiple sources, including the constant muscular effort required to stabilize unstable joints, disrupted sleep due to chronic pain, autonomic dysfunction, mitochondrial stress, and the physiological burden of managing a complex chronic illness.

• Pelvic floor dysfunction affects many people with EDS, particularly women, and includes pelvic organ prolapse, bladder and bowel incontinence, pelvic pain, and sexual dysfunction. The pelvic floor is a complex of connective tissues and muscles, and when the connective tissue component is defective, the entire structure is affected.

Why Diagnosis Takes So Long

The diagnostic journey for EDS is notoriously prolonged and difficult, and understanding why helps to contextualize the frustration and suffering that patients experience.

First, there is no definitive laboratory test for hypermobile EDS, the most common subtype. Diagnosis relies on clinical criteria, physical examination, personal and family history, and the clinical judgment of a knowledgeable provider. Most physicians receive little to no training in EDS during medical school or residency, and hypermobility is frequently dismissed as benign or irrelevant.

Second, the multisystem nature of EDS means that patients are typically managed by multiple specialists who may not communicate with each other or recognize the common thread connecting their patient's diverse complaints. A gastroenterologist may treat the motility issues without knowing about the dysautonomia. A cardiologist may manage the POTS without knowing about the EDS. The patient falls through the gaps between specialties.

Third, many standard diagnostic tests in EDS come back normal or unremarkable, which leads providers to conclude that nothing serious is wrong. X-rays may look normal. Blood work may be within range. MRIs may not capture the dynamic instability that occurs with movement. The absence of abnormal findings is incorrectly interpreted as the absence of pathology.

Fourth, women with EDS face an additional barrier in a medical system that has historically dismissed women's pain and complex symptoms as psychological or exaggerated. EDS affects women disproportionately in terms of symptom severity and diagnostic difficulty, and gender bias in medicine continues to compound an already difficult diagnostic process.

The Genetic Foundation and the Environmental Conversation

For most EDS subtypes, the underlying genetic mutations have been identified. For hypermobile EDS, the genetics are more complex and remain under active investigation, but the familial pattern is clear and the heritable nature is well-established.

Understanding EDS as a genetic condition is essential. But it is also important to recognize that genetics rarely tell the whole story. Gene expression, the severity of symptoms, the presence and intensity of comorbidities, and the overall trajectory of the condition are all influenced significantly by the environment in which those genes are expressed.

Nutritional status, gut health, inflammatory burden, stress load, sleep quality, and environmental exposures all influence how EDS manifests and how the body copes with the challenges the condition creates. This is where a root cause perspective becomes genuinely valuable, not as an alternative to understanding EDS as a genetic condition, but as a complement to it.

A Root Cause Perspective on Supporting the Body with EDS

Root cause medicine does not claim to fix EDS. The collagen defect is real and it is genetic. What root cause thinking offers is a framework for supporting the body as intelligently as possible given the challenges that collagen dysfunction creates, and for addressing the modifiable factors that significantly influence symptom severity and quality of life.

Nutrition for collagen support

While nutrition cannot correct the underlying genetic defect in collagen synthesis, it can optimize the raw materials and cofactors that the body uses in whatever collagen production is possible.Vitamin C is an essential cofactor for collagen synthesis, required for the hydroxylation of proline and lysine, the amino acids that give collagen its characteristic triple helix structure.

Deficiency impairs whatever collagen the body is capable of making. Many people with EDS report worsening symptoms when vitamin C intake is low and improvement with consistent supplementation. Whole food sources include bell peppers, kiwi, citrus, strawberries, and broccoli. Supplemental vitamin C at 500 to 2,000mg daily in divided doses is commonly used.Protein intake is foundational, as collagen and all connective tissues are protein-based. Adequate protein with attention to glycine-rich sources is particularly relevant, as glycine is the most abundant amino acid in collagen. Bone broth, collagen peptide supplements, and gelatin are concentrated sources of glycine and other collagen-related amino acids.

Copper and zinc are essential cofactors in collagen crosslinking, the process by which collagen fibers achieve their structural integrity. Deficiencies in either mineral impair the quality of whatever collagen the body produces.Manganese, silicon, and vitamin K2 also play supporting roles in connective tissue health and are worth considering as part of a comprehensive nutritional approach.

An anti-inflammatory dietary pattern reduces the ongoing inflammatory burden that worsens pain, fatigue, and mast cell reactivity in EDS. Emphasizing whole foods, omega-3 rich proteins, colorful vegetables and fruits, and fermented foods while minimizing ultra-processed foods, industrial seed oils, and refined sugars creates a more supportive internal environment.

Gut health

Given the high prevalence of gastrointestinal involvement in EDS, gut health deserves specific attention. The combination of mechanical issues (poor motility from connective tissue defects), SIBO, increased intestinal permeability, and MCAS-driven food reactions creates a complex gut picture that benefits from careful, individualized support.

Probiotics, digestive enzymes, L-glutamine for gut lining support, and a low-histamine diet for those with significant MCAS overlap are among the tools that can make a meaningful difference. Working with a practitioner who understands both EDS and gut health is important, as gut interventions in EDS require a nuanced approach.

MCAS management

For those with EDS-associated MCAS, reducing the mast cell trigger load is a primary goal. This involves identifying and minimizing individual triggers (which vary considerably between people), following a low-histamine diet during flares, supporting histamine degradation through DAO enzyme supplementation, and using natural mast cell stabilizers such as quercetin, vitamin C, and luteolin alongside whatever medical management is appropriate.

Magnesium

Magnesium deficiency is common in EDS and contributes significantly to several key symptoms, including muscle cramping, pain sensitization, poor sleep, anxiety, and autonomic dysregulation. Magnesium glycinate at 300 to 400mg daily is well tolerated and addresses multiple symptom domains simultaneously.

Sleep

Chronic pain and autonomic dysfunction make restorative sleep profoundly difficult for many people with EDS. Poor sleep, in turn, amplifies pain perception, worsens fatigue, increases mast cell reactivity, and impairs the tissue repair that needs to occur during rest. Prioritizing sleep hygiene, addressing pain management before bed, and supporting the nervous system's ability to downregulate in the evening are all important components of EDS management.

Movement and physical therapy

Movement is essential in EDS but must be approached with significant care. Exercise that strengthens the muscles surrounding unstable joints is among the most effective interventions for reducing pain and improving function.

Low-impact, stability-focused modalities such as swimming, Pilates, and specific physical therapy protocols designed for hypermobility are generally better tolerated than high-impact or heavy-loading activities.

Working with a physical therapist who understands hypermobility and EDS is strongly recommended, as standard exercise prescriptions can be harmful rather than helpful if they do not account for joint instability.

Nervous system regulation

The chronic pain, autonomic dysfunction, and psychological burden of living with EDS place enormous strain on the nervous system. Many people with EDS develop central sensitization, a state in which the nervous system becomes hypersensitive and amplifies pain signals disproportionately to tissue damage.

Practices that support parasympathetic activation, including diaphragmatic breathing, gentle movement, mindfulness, somatic therapies, and adequate rest, are not peripheral lifestyle suggestions. They are central to managing both the autonomic dysfunction and the pain amplification that characterize EDS for many patients.

What People with EDS Need Most

Beyond any specific supplement or intervention, what people with EDS need most is to be believed, to be heard, and to be cared for by providers who understand the complexity and legitimacy of what they are experiencing.

EDS is real. The pain is real. The fatigue is real. The systemic impact is real. And the suffering that comes from years of being dismissed, misdiagnosed, and undertreated is real in ways that extend far beyond the physical.

Awareness Month matters because every person who learns to recognize the signs of EDS is a potential turning point in someone's diagnostic journey. Every practitioner who expands their knowledge is another door that opens for a patient who has spent years knocking on closed ones.If you suspect you or someone you love may have EDS, seek evaluation from a provider with expertise in connective tissue disorders and hypermobility.
