Everyone will experience different symptoms and to varying degrees. Most people will only experience some of the symptoms listed below.

Symptoms of HSD can include

  • Pain
  • Fatigue
  • Frequent injuries, including dislocations, subluxations, sprains and microtraumas
  • Poor proprioception/clumsiness

Issues with bladder and bowel, the pelvic floor, and the autonomic nervous system  (e.g. fainting, and dizziness when standing) are also common in people with HSD.

Many of the symptoms listed below seem to be common in patients with HSD or hEDS but the links are not yet understood.

An iceburg in the water. Above the water "Joint hypermobility and hyperextension, sprains, strains, subluxations and dislocations." Below the waterline is the following list "Chronic pain, poor wound healing, bladder and pelvic problems, Chronic fatigue, Autonomic dysfunction/PoTS, Easy bruising, Soft or stretchy skin, Gastrointestinal dysfunction, Poor proprioception, Anxiety and phobic states and depression."

Research has indicated that there is a link between autistic spectrum disorders and hypermobility related disorders, but again the link is not yet understood.


The severity of symptoms can vary hugely both between individuals and over time. Some can be mildly affected, with intermittent issues that have very little impact on day to day life – especially when managed through appropriate physiotherapy, pacing, and joint care. Other individuals may be much more severely affected.

It is important to recognise that HSD is not inherently milder than hEDS, in fact recent studies have shown no difference in symptom severity. Management is based on addressing the current symptoms.
