Hypermobile Ehlers-Danlos Syndrome (hEDS)
Hypermobile Ehlers-Danlos Syndrome (hEDS) is a heritable connective tissue disorder characterized by generalized joint hypermobility, skin hyperextensibility, and tissue fragility. Connective tissue is the 'glue' of the body, so defects can lead to widespread multi-systemic issues.
Common Symptoms
Causes & Triggers
- Genetic inheritance (autosomal dominant), though the specific gene(s) for hEDS are currently unknown
- Hormonal fluctuations (relaxin and progesterone can increase laxity)
- Physical trauma or repetitive strain
Diagnosis
Diagnosis is clinical, based on the 2017 International Classification of the Ehlers-Danlos Syndromes. It requires meeting specific criteria including generalized joint hypermobility (measured by the Beighton score), evidence of syndromic features or family history, and exclusion of other connective tissue disorders.
