"You're so flexible!" For years it seemed like a gift. Until it turned into daily pain, repeated sprains, joints that "pop out of place" — and a pilgrimage through clinics hearing that everything is normal.
Hypermobility accompanied by symptoms is not normal. It is a clinical sign that deserves investigation.
What Ehlers-Danlos Syndrome is
Ehlers-Danlos Syndrome (EDS) is a group of hereditary connective tissue conditions — the "framework" that supports joints, skin, vessels and organs. The core problem lies in collagen: the protein that should give tissues balanced firmness and elasticity.
The most common subtype is hypermobile EDS (hEDS), characterized by:
- Joints that move beyond the normal range (hypermobility)
- Chronic musculoskeletal pain
- Frequent dislocations and subluxations
- Soft, velvety skin, sometimes with atypical scarring
- Significant fatigue
Why diagnosis takes decades
A person with EDS is rarely referred for the right symptom. They are treated in pieces: physiotherapy for the knee, painkillers for the pain, anxiolytics for the "anxiety." The international average between first symptom and diagnosis exceeds 10 years — because few professionals connect the dots.
And the dots go beyond joints. EDS frequently coexists with:
- Dysautonomia/POTS: dizziness on standing, tachycardia, orthostatic intolerance
- Mast Cell Activation Syndrome (MCAS): multisystem allergy-like reactions
- Digestive symptoms: reflux, constipation, dysmotility
- Sleep disturbances and non-restorative sleep
This triad — EDS, dysautonomia and MCAS — is recognized in the literature and completely changes case management.
How diagnosis is made
For the hypermobile subtype, diagnosis is clinical, based on the 2017 international criteria:
- Beighton score: standardized scoring of joint hypermobility
- Systemic criteria: skin features, dislocation history, chronic pain, among others
- Exclusion of other connective tissue diseases
No blood or genetic test confirms hEDS — which makes a specialized physical exam and detailed history irreplaceable.
What to do with the suspicion
If you recognized yourself: record your dislocations and sprains, photograph hypermobility maneuvers you can do, list the symptoms that seem "unrelated" to each other. That collection is exactly the material of a good investigation.
Recognizing patterns others miss — that is what changes the trajectory of those living with an underdiagnosed condition.
