For a small percentage of the population, instead of being advantageous, hypermobility may be associated with joint and ligament injuries, pain, fatigue and other symptoms. Hypermobility can also be a sign of a more serious underlying condition, which are often passed down through the generations. These conditions are known as Heritable Disorders of Connective Tissue (HDCT).
When our group of medical advisors use the phrase ‘hypermobility syndromes’ they are referring to the group of HDCT in which symptomatic-hypermobility is now recognised as a common feature. The most common of these is Joint Hypermobility syndrome or Hypermobility Spectrum Disorder (HSD), which used to be thought by many experts as part of the same spectrum as hypermobile Ehlers-Danlos syndrome (hEDS). HDCTs also include other rarer variants of Ehlers-Danlos syndrome, such as the classical (cEDS) and vascular (vEDS) types, Marfan syndrome, and to differing degrees Osteogenesis Imperfecta and Stickler syndrome. It is important to appreciate that each HDCT has its own differing symptoms and complications, as well as also sharing a broader commonality. For instance Marfan syndrome and vascular Ehlers-Danlos syndrome, may have potentially life threatening complications and therefore have very different needs; classical Ehlers-Danlos syndrome has potentially more severe and differing symptoms from the hypermobile EDS; and in Osteogenesis Imperfecta a person is more likely to suffer fractures either spontaneously or after minimal trauma.
