Your Complete Guide to Hypermobile Ehlers-Danlos Syndrome (hEDS)

Last updated: March 27, 2026

Hypermobile Ehlers-Danlos Syndrome (hEDS) is a multisystemic connective tissue disorder often accompanied by POTS and MCAS. Diagnosis relies on the 2017 clinical criteria and Beighton score. Management requires multidisciplinary care, physical therapy, and symptom pacing to improve quality of life.

Key Takeaways

• Hypermobile Ehlers-Danlos Syndrome (hEDS) and Hypermobility Spectrum Disorder (HSD) often require a long diagnostic odyssey due to their complex, multisystemic nature.
• Diagnosis is based on the 2017 international diagnostic criteria, which utilizes the Beighton score to assess joint hypermobility.
• Many patients experience a symptom 'trifecta' of hEDS alongside Postural Orthostatic Tachycardia Syndrome (POTS) and Mast Cell Activation Syndrome (MCAS).
• Managing hEDS requires a multidisciplinary care team, specialized physical therapy, joint protection strategies, and energy pacing.

Frequently Asked Questions

What is the hEDS, POTS, and MCAS trifecta?

The hEDS 'trifecta' refers to the common co-occurrence of Hypermobile Ehlers-Danlos Syndrome (hEDS), Postural Orthostatic Tachycardia Syndrome (POTS), and Mast Cell Activation Syndrome (MCAS). Patients frequently experience interconnected symptoms across all three conditions.

How do doctors diagnose hEDS?

hEDS is diagnosed clinically using the strict 2017 international diagnostic criteria, which includes evaluating joint flexibility with the Beighton score. Genetic testing is typically used to rule out other rare types of Ehlers-Danlos Syndrome or related connective tissue disorders.

How should I manage a flare-up of multiple hEDS symptoms at once?

During a multisystem flare-up, it is crucial to communicate with your care team according to your established plan. Pacing your energy and coordinating with your doctors can help you safely manage worsening symptoms across different body systems.

How can I prepare for appointments with a new hEDS doctor?

When seeing new doctors, it helps to organize your medical history, imaging, and test results into a single binder or folder. Bringing a supportive friend or family member to take notes can also help you advocate for yourself effectively.
