Overview

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.

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. Because vascular Ehlers-Danlos syndrome can have serious potential complications in pregnancy, you may want to talk to a genetic counselor before starting a family.

Symptoms

There are many different types of Ehlers-Danlos syndrome, but the most common signs and symptoms include:

  • Overly flexible joints. Because the connective tissue that holds joints together is looser, your joints can move far past the normal range of motion. Joint pain and dislocations are common.
  • Stretchy skin. Weakened connective tissue allows your skin to stretch much more than usual. You may be able to pull a pinch of skin up away from your flesh, but it will snap right back into place when you let go. Your skin might also feel exceptionally soft and velvety.
  • Fragile skin. Damaged skin often doesn't heal well. For example, the stitches used to close a wound often will tear out and leave a gaping scar. These scars may look thin and crinkly.

Symptom severity can vary from person to person and depends on the specific type of Ehlers-Danlos syndrome that you have. The most common type is called hypermobile Ehlers-Danlos syndrome.

Vascular Ehlers-Danlos syndrome

People who have vascular Ehlers-Danlos syndrome often share distinctive facial features of a thin nose, thin upper lip, small earlobes and prominent eyes. They also have thin, translucent skin that bruises very easily. In fair-skinned people, the underlying blood vessels are very visible through the skin.

Vascular Ehlers-Danlos syndrome can weaken your heart's largest artery (aorta), as well as the arteries to other regions of your body. A rupture of any of these larger blood vessels can be fatal. The vascular type can also weaken the walls of the uterus or large intestines — which also may rupture.

Causes

Different types of Ehlers-Danlos syndrome are associated with a variety of genetic causes, some of which are inherited and passed on from parent to child. If you have the most common form, hypermobile Ehlers-Danlos syndrome, there's a 50% chance that you'll pass on the gene to each of your children.

Complications

Complications depend on the types of signs and symptoms you have. For example, overly flexible joints can result in joint dislocations and early-onset arthritis. Fragile skin may develop prominent scarring.

People who have vascular Ehlers-Danlos syndrome are at risk of often fatal ruptures of major blood vessels. Some organs, such as the uterus and intestines, also may rupture. Pregnancy can increase the risk of a rupture in the uterus.

Prevention

If you have a personal or family history of Ehlers-Danlos syndrome and you're thinking about starting a family, you may benefit from talking to a genetic counselor — a health care professional trained to assess the risk of inherited disorders. Genetic counseling can help you understand the inheritance pattern of the type of Ehlers-Danlos syndrome that affects you and the risks it poses for your children.

FAQs

What is the most common cause of Ehlers-Danlos syndrome? ›

The different types of EDS are caused by faults in certain genes that make connective tissue weaker. Depending on the type of EDS, the faulty gene may have been inherited from 1 parent or both parents. Sometimes the faulty gene is not inherited, but occurs in the person for the first time.

What triggers EDS symptoms? ›

Ehlers-Danlos Syndrome Causes

EDS happens when your body doesn't make a protein called collagen in the right way. Collagen helps form the connections that hold your body's bones, skin, and organs together. If it's not as strong as it should be, those structures become weak and can't function like they should.

Who is most likely to get Ehlers-Danlos syndrome? ›

You may have an increased risk of EDS if one or both of your biological parents have it. Similarly, if you have EDS, you might pass the mutation that caused it to your biological children. Talk to a healthcare provider about your risk of inheriting or passing on Ehlers-Danlos syndrome in your biological family.

How to help Ehlers-Danlos syndrome? ›

Exercises to strengthen the muscles and stabilize joints are the primary treatment for Ehlers-Danlos syndrome. Your physical therapist might also recommend specific braces to help prevent joint dislocations.

At what age is Ehlers-Danlos usually diagnosed? ›

Since Ehlers-Danlos Syndrome can be present at birth or shortly thereafter, it is not unusual for it to be diagnosed during a child's toddler years. This can be done by looking at their specific symptoms, family history, urine testing and skin biopsies. It can sometimes be helpful to perform a cardiac ultrasound.

What autoimmune disease is associated with Ehlers-Danlos syndrome? ›

Mast cell activation disorder is a malfunctioning of part of the immune system, where a type of immune cell (mast cells) release an excess of inflammatory chemicals such as histamine, causing allergy-like symptoms throughout the body. Mast cell dysregulation may be linked to some types of Ehlers-Danlos Syndromes.

What should people with EDS avoid? ›

Limiting gluten or eating a gluten-free diet does not have to cost a ton, nor does it mean that you can only shop in the gluten free aisle! But limiting gluten can make a huge difference in your life. Gluten can cause inflammation in the body which can cause pain or other complications when you have EDS.

What can be mistaken for EDS? ›

Patients with EDS, especially those with EDS hypermobility type, are often misdiagnosed with conditions such as fibromyalgia, chronic fatigue syndrome, or depression, given the overlap of symptoms and the psychosocial impact they have on the patient.

What vitamin deficiency is EDS? ›

Micronutrient deficiencies are often: evident in persons with EDS (e.g., magnesium, vitamin B6, vitamin D, vitamin B12, vitamin C). known to exacerbate symptoms associated with EDS and the secondary conditions arising from EDS.

What are the red flags of Ehlers-Danlos syndrome? ›

People who have vascular Ehlers-Danlos syndrome often share distinctive facial features of a thin nose, thin upper lip, small earlobes and prominent eyes. They also have thin, translucent skin that bruises very easily. In fair-skinned people, the underlying blood vessels are very visible through the skin.

What are three of the cardinal features of Ehlers-Danlos? ›

Ehlers-Danlos syndrome (EDS) is the term used for a group of relatively rare genetic disorders of connective tissue that are characterized by one or another of several features, including skin hyperextensibility, joint hypermobility, and tissue fragility.

What is EDS life expectancy? ›

Does EDS affect breasts? ›

People with hypermobile EDS often experience pain from large breasts. Patients with hEDS often have aggravated symptoms of macromastia, or enlarged breasts.

What does EDS pain feel like? ›

Pain. Chronic pain in the Ehlers–Danlos syndromes, especially in hypermobile EDS, is very common and may be severe. It may be widespread or it may be limited to one area of the body such as a limb. Headaches and gastrointestinal discomfort can occur as well as joint, muscle and nerve pain.

What medications should be avoided with Ehlers-Danlos syndrome? ›

by Drugs.com

With Ehlers-Danlos syndrome (EDS), experts recommend avoiding drugs that increase your risk of bleeding—such as anticoagulants and antiplatelet agents—because those affected with EDS are at higher risk for bruising and injury.

What is the life expectancy of someone with EDS? ›

Patients with vascular EDS have an average life expectancy of 48 years. About 80% of patients might have a critical event by the age of 40 years. The lifespan of a patient with kyphoscoliosis EDS is reduced due to two reasons: Involvement of the blood vessels.
