What Is Hypermobile Ehlers-Danlos Syndrome (hEDS)?

Of the thirteen recognized types of Ehlers-Danlos Syndrome, hypermobile Ehlers-Danlos Syndrome — commonly called hEDS — is the most common. It is also the type that inspired the founding of The Andrea Foundation For EDS (TAFFEDS).

This article provides a plain-language overview of hEDS. It is not medical advice. If you have concerns about your health or the health of someone you love please consult a qualified healthcare professional.

What Is hEDS?

Hypermobile Ehlers-Danlos Syndrome is a hereditary connective tissue disorder. The most recognized feature of hEDS is generalized joint hypermobility — joints that move beyond what is considered the normal range of motion.

But hEDS is much more than flexible joints. People with hEDS often experience chronic widespread pain that can be severe and debilitating. They frequently experience persistent fatigue that does not improve with rest. Many have digestive symptoms, heart rate irregularities, skin sensitivity, anxiety, depression, and a wide range of other symptoms that affect nearly every area of daily life.

How Is hEDS Different from Being Double-Jointed?

Being double-jointed — or having joint hypermobility — is common and often benign. hEDS is different because the hypermobility occurs alongside other features and is associated with significant symptoms that affect quality of life, daily functioning, and overall health.

Not everyone with flexible joints has hEDS. And not every person with hEDS experiences all possible symptoms. The presentation of hEDS varies significantly from person to person.

Common Conditions Associated with hEDS

Many people with hEDS also live with related conditions. POTS — Postural Orthostatic Tachycardia Syndrome — affects heart rate regulation and is common in people with hEDS. MCAS — Mast Cell Activation Syndrome — affects immune responses and is also associated with hEDS. Dysautonomia, gastrointestinal dysmotility, and chronic fatigue conditions are also frequently seen alongside hEDS.

The Personal Connection of The Andrea Foundation For EDS

The founder of The Andrea Foundation For EDS (TAFFEDS) spent sixteen years searching for answers for her daughter who was born with hEDS. During those sixteen years, her daughter was dismissed, misdiagnosed, and left without the support she needed — not because the answers were not there but because the awareness was not.

That experience is why this foundation exists. We believe that with greater awareness more people can reach answers — and support — sooner.
