Dilation and/or rupture (aneurysm) of ascending aorta
Cardiovascular autonomic dysfunction such as postural orthostatic tachycardia syndrome
Raynauds phenomenon
Varicose veins
Heart murmur

Other manifestations
Hiatal hernia
Gastroesophageal reflux
Poor gastrointestinal motility
Dysautonomia
Gorlins sign (touch tongue to nose)

Flat feet
Tracheobronchomalacia / tracheal collapse
Collapsed lung (spontaneous pneumothorax)
Nerve disorders (carpal tunnel syndrome, acroparesthesia, neuropathy, including small fiber neuropathy)
Insensitivity to local anesthetics
Arnold–Chiari malformation
Platelet aggregation failure (platelets do not clump together properly)
Mast cell disorders (including mast cell activation syndrome and mastocytosis)
Pregnancy complications: increased pain, mild to moderate peripartum bleeding, cervical insufficiency, uterine tearing, or premature rupture of membranes
Hearing loss may occur in some types
Eye: Nearsightedness, retinal tearing and retinal detachment, keratoconus, blue sclera, dry eye, Sjogrens syndrome, lens subluxation, angioid streaks, epicanthal folds, strabismus, corneal scarring, brittle cornea syndrome, cataracts, carotid-cavernous sinus fistulas, macular degeneration
Craniocervical instability: caused by trauma(s) to the head and neck areas such as concussion and whiplash. Ligaments in neck are unable to heal properly, so the neck structure does not have the ability to support the skull, which can then sink into the brain stem, blocking the flow of cerebrospinal fluid, leading to issues related to the autonomic nervous system failing to work properly. Osteoporosis and osteopenia are associated with EDS and symptomatic joint hypermobility
There is some evidence that EDS may be associated with greater than expected frequencies of neurodevelopmental disorders such as attention deficit hyperactivity disorder (ADHD) and other learning, communication and motor issues, including autism spectrum conditions and Tourette syndrome. Because it is often undiagnosed or misdiagnosed in childhood, some instances of EDS have been mischaracterized as child abuse.
People are commonly misdiagnosed with fibromyalgia, bleeding disorders, or other disorders that can mimic EDS symptoms. Because of these similar disorders and complications that can arise from an unmonitored case of EDS, a correct diagnosis is important. Pseudoxanthoma elasticum is worth consideration in diagnosis. Management
No cure for Ehlers–Danlos syndromes is known, and treatment is supportive. Close monitoring of the cardiovascular system, physiotherapy, occupational therapy, and orthopedic instruments (e.g., wheelchairs, bracing, casting) may be helpful. This can help stabilize the joints and prevent injury. Orthopedic instruments are helpful for the prevention of further joint damage, especially for long distances. People should avoid activities that cause the joint to lock or overextend.A physician may prescribe casting to stabilize joints. Physicians may refer a person to an orthotist for orthotic treatment (bracing). Physicians may also consult a physical and/or occupational therapist to help strengthen muscles and to teach people how to properly use and preserve their joints.Aquatic therapy promotes muscular development and coordination. With manual therapy, the joint is gently mobilized within the range of motion and/or manipulations. If conservative therapy is not helpful, surgical joint repair may be necessary. Medication to decrease pain or manage cardiac, digestive, or other related conditions may be prescribed. To decrease bruising and improve wound healing, some people have responded to vitamin C. Medical care workers often take special precautions because of the sheer number of complications that tend to arise in people with EDS.
