Possible vascular or organ rupture
Sudden severe chest, abdominal, flank, head or limb pain, collapse, focal neurology, haemoptysis or major unexplained bleeding in suspected vascular EDS can indicate arterial dissection, rupture, pneumothorax or bowel perforation.
Action: Call emergency vascular-capable services, state the possible connective-tissue disorder, minimise traumatic procedures, obtain rapid specialist-led imaging and involve vascular surgery, interventional radiology, anaesthesia and genetics-informed teams.
Synopsis
Assess symptomatic joint hypermobility systematically, distinguish hypermobile Ehlers-Danlos syndrome from hypermobility spectrum disorder and monogenic EDS subtypes, recognise vascular danger, and coordinate stabilising rehabilitation, symptom care, genetics and reproductive planning.
Joint hypermobility is a physical trait; HSD or hEDS requires symptoms or associated features after exclusion of another explanation, and neither follows from flexibility alone.
Score Beighton manoeuvres correctly: the 2017 hEDS threshold is at least 5 of 9 from puberty through age 50 and at least 4 after 50; historical questions help when one point below.
All hEDS groups are required: generalised hypermobility; at least two of Feature A with five systemic findings, Feature B with an independently affected first-degree relative, or Feature C with qualifying pain or instability; and complete exclusions.
Key red flags
Arterial rupture or dissection, spontaneous bowel perforation, uterine rupture, pneumothorax or unexplained sudden death in a young first-degree relative raises vascular EDS and warrants specialist genetics assessment.
Investigation priorities
01
First-line structured assessmentFirst stepFirst line
Confirm current and historical hypermobility, document functional consequences and detect signs requiring another route.
Management branches
First-line classificationSeparate trait, HSD, hEDS and rare subtype
Recurrent pain, instability or systemic connective-tissue features accompany current or historical hypermobility.
Measure Beighton score correctly, document non-Beighton and historical mobility, and establish whether symptoms are plausibly related rather than incidental.
Apply all hEDS criteria groups, examining systemic features and excluding inflammatory, neuromuscular, skeletal and alternative heritable disorders.
Preferred rehabilitationBuild active joint control
Instability, pain, fatigue or movement fear limits function without fracture, unreduced dislocation or emergency.
Key medicines
Paracetamol for acute local painUse 500 mg–1 g orally at intervals of at least four hours when required, maximum 4 g in 24 hours for a suitable adult; lower the ceiling with low weight, frailty or liver risk.
Topical diclofenac gelApply a product-specific amount to focal pain, commonly 2–4 g of 1.16% gel three or four times daily for a brief trial, without exceeding the product maximum.
National guidance is shown before implementation-dependent detail. Typical adult dose examples remain subject to patient factors, contraindications and the live BNF or specialist protocol. Source check completed 27 Aug 2026; clinical approval remains outstanding.
