Fatigue and Post-Exertional Crash in Hypermobility (hEDS/HSD)

What the Research Says About Post-Exertional Fatigue

A 2014 study by De Wandele and colleagues compared 39 people with the hypermobility type of EDS to 35 healthy controls and found orthostatic intolerance (dizziness, fainting, and related symptoms tied to standing) in 74% of the hEDS group versus 34% of controls. In that same study, dysautonomia correlated with worse fatigue, more pain, and lower quality of life. You may see this figure quoted elsewhere as "about 78%." That appears to be a misreading of the original data; 74% is the number the study actually reports.

A separate 2024 review looked across multiple studies and found dysautonomia prevalence in hEDS ranging from 31% to 94%, depending on the study and how dysautonomia was measured. That's a wide spread, and it's a different figure from the De Wandele study above. The two shouldn't be blended into one number. The honest summary is: dysautonomia shows up often in hEDS/HSD, but how often depends heavily on which study you're reading.

Pacing and Energy Management Strategies That Have Been Tested

A small 2023 randomized controlled trial (n=36) tested compression garments combined with physical therapy against physical therapy alone. The compression-plus-PT group showed better balance and less postural sway, both right after treatment and again at a four-week follow-up. It's worth being precise about what this trial measured: balance and postural sway, not fatigue itself. It's relevant to this cluster because postural sway and dysautonomia-linked symptoms often travel together, but it isn't direct evidence that compression reduces post-exertional crashes.

Other Approaches to Chronic Fatigue in hEDS/HSD

Pacing, sometimes called energy-conservation planning, shows up repeatedly in discussions of dysautonomia-linked fatigue. It usually comes up alongside tracking symptoms against activity to spot patterns before a crash, and graded activity planning that increases load slowly rather than all at once. None of this is something to figure out alone from a webpage; a physical therapist or occupational therapist familiar with dysautonomia can help build a pacing plan suited to your own pattern of symptoms.

Fatigue-Tracking Tools: What's Actually Verified

SPIO and Cerecare are real compression garment brands that have been used in registered EDS-related clinical trials, including the balance study above. Visible, an app and armband pairing, is marketed specifically at pacing for energy-limiting chronic illness. It's a real product built for this use case, though we haven't found trial data testing whether it improves outcomes. General wellness wearables like Oura, Whoop, or an Apple Watch track heart-rate variability and could theoretically support pacing decisions. It's worth knowing that Oura explicitly states its ring is not a medical device; none of these are validated for managing dysautonomia symptoms, and they measure trends, not diagnoses.
