A Basic Understanding of Ehlers-Danlos Syndrome (EDS)

A plain-language summary of the connective tissue disorder

Ehlers-Danlos Syndrome, or EDS for short, is a group of genetic conditions that affect the connective tissue in the body. Connective tissue is like the glue that holds everything together—your skin, joints, blood vessels, and organs all rely on it to stay strong and work properly.

In people with EDS, this glue is weak or stretchy when it shouldn’t be. That means joints can move too far, skin may be unusually soft or fragile, and blood vessels or organs can be more prone to injury. This isn’t just about being flexible—it’s a medical condition that can affect nearly every system in the body.

What is connective tissue?

Think of connective tissue as the scaffolding or support beams of the body. It’s made up of proteins like collagen that give strength, structure, and flexibility. When these proteins are made incorrectly because of a genetic mutation, the support system weakens—and that leads to the wide range of symptoms seen in EDS and other connective tissue disorders.

Why the Zebra?

In medicine, doctors are taught, “When you hear hoofbeats, think horses—not zebras,” meaning common conditions are more likely than rare ones. But for those of us with Ehlers-Danlos Syndrome and other rare diseases, we are the zebras. We may look fine on the outside, but our symptoms don’t follow the usual rules. The zebra has become our symbol—a reminder that rare isn’t impossible, and that doctors should look beyond the obvious. We wear our stripes with pride.

Common symptoms of EDS include:

  • Joint hypermobility (joints that bend too far or dislocate easily)

  • Chronic pain or fatigue

  • Frequent injuries like sprains or subluxations

  • Fragile skin that bruises or tears easily

  • Digestive issues, fainting, or dizziness (due to nervous system involvement)

  • Slow wound healing or stretchy skin (in some types)

EDS isn’t the only connective tissue disorder. Others include:

  • Marfan Syndrome – Often affects the heart, eyes, and skeleton. People tend to be tall with long limbs.

  • Loeys-Dietz Syndrome – Similar to Marfan but with unique vascular features and facial traits.

  • Stickler Syndrome – Affects joints, eyes, and hearing, often diagnosed in children.

  • Osteogenesis Imperfecta – Known as “brittle bone disease,” it causes fragile bones and easy fractures.

  • Cutis Laxa – Causes loose, sagging skin and can affect internal organs.

  • Hypermobile Spectrum Disorders (HSD) – Similar to the hypermobile type of EDS but doesn’t meet all diagnostic criteria.

Why diagnosis and awareness matter

These conditions are often misunderstood or misdiagnosed, especially since they can look like anxiety, clumsiness, or general fatigue. Early diagnosis can help people get the right treatments, physical therapy, and support to manage symptoms and improve quality of life.

The bottom line:

EDS and related connective tissue disorders are real, often invisible, and deeply impactful. But with the right knowledge, care, and support, people living with these conditions can find ways to manage their health and live well.
