Ehlers-Danlos syndrome (EDS) is a group of inherited disorders marked by extremely loose joints, very stretchy (hyperelastic) skin that bruises easily, and easily damaged blood vessels.
There are at least 13 types of EDS. Hypermobile EDS is the most common type (90% of cases). Other forms include the classic and vascular forms.

The variant collagen leads to the symptoms associated with EDS. In some forms of the syndrome, the rupture of internal organs or abnormal heart valves can occur.

People with EDS generally have a normal life span. Intelligence is normal.
Those with the rare vascular type of EDS are at greater risk for rupture of a major organ or blood vessel. These people have a high risk for sudden death.
Possible complications of EDS include:
Contact your provider for an appointment if you have a family history of EDS and you are concerned about your risk or are planning to start a family.
Contact your provider for an appointment if you or your child has symptoms of EDS.
Genetic counseling is recommended for prospective parents with a family history of EDS. Those planning to start a family should be aware of the type of EDS they have and how it is passed down to children. This can be determined through testing and evaluations suggested by your provider or genetic counselor.
Identifying any significant health risks may help prevent severe complications by vigilant screening and lifestyle alterations.
