Ehlers-Danlos syndrome is a group of inherited disorders that affect your connective tissues — primarily your skin, joints and blood vessel walls. Connective tissue is a complex mixture of proteins and other substances that provides strength and elasticity to the underlying structures in your body.
People who have Ehlers-Danlos syndrome usually have overly flexible joints and stretchy, fragile skin. This can become a problem if you have a wound that requires stitches, because the skin often isn't strong enough to hold them.
A more severe form of the disorder, called vascular Ehlers-Danlos syndrome, can cause the walls of your blood vessels, intestines or uterus to rupture. If you have vascular Ehlers-Danlos syndrome, you may want to talk to a genetic counselor before starting a family.
