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 provide strength and elasticity to the underlying structures in your body.
Joint hypermobility syndrome is a connective tissue disorder. Thick bands of tissue (ligaments) hold your joints together and keep them from moving too much or too far out of range. In people with joint hypermobility syndrome, those ligaments are loose or weak. If you have joints that are more flexible than normal and it causes you pain, you may have joint hypermobility syndrome.
