Bloating, Reflux, and Gut Motility in hEDS/HSD

How Common Are GI Symptoms in hEDS/HSD?

A retrospective study out of the Cleveland Clinic, reviewing records from 2007 to 2017 and published in 2020 in the journal Cureus, looked at 218 patients with hEDS. At the time of diagnosis, 62.3% of them had at least one gastrointestinal symptom on record, including bloating, reflux, abdominal pain, or irregular bowel habits.

That's a symptom count, not a diagnosis of a motility disorder. Having a GI symptom doesn't automatically mean something measurable is wrong with how the gut moves. It just means the symptom was there.

What GI Motility Testing Shows in Hypermobility

Of those 218 patients, a smaller group of 42 went on to have formal motility testing, the kind of study that measures how food actually moves through the esophagus, stomach, or intestines rather than relying on reported symptoms alone. Within that 42-patient group, 76.2% showed some form of measurable dysmotility.

That number is easy to misquote as applying to everyone with hEDS, or even to all 218 patients in the study. It doesn't. It describes the subset who were tested, who were likely referred for testing because their symptoms were already significant enough to warrant it. Within that tested group, the most common finding was gastroparesis (delayed stomach emptying), at 42.8%. Esophageal dysmotility and delayed transit through the small bowel or colon each showed up in 11.9% of the tested group, and a more generalized, whole-gut pattern of slow motility appeared in 9.5%.

The same study found that POTS (postural orthostatic tachycardia syndrome, a form of dysautonomia that's also common in hEDS/HSD) was a significant predictor of which patients had GI dysmotility. That connection between the autonomic nervous system and gut function is one reason GI symptoms in hEDS/HSD are increasingly treated as part of a broader pattern rather than an isolated digestive complaint.

Dietary and Motility Approaches for Hypermobile GI Symptoms

A 2025 Clinical Practice Update from the American Gastroenterological Association, along with guidance from the Ehlers-Danlos Society, points toward dietary approaches as a first-line strategy for managing GI symptoms tied to dysmotility. For gastroparesis specifically, that often means a small-particle or gastroparesis-friendly diet: smaller, more frequent meals, lower in fat and insoluble fiber, which are harder for a slow-moving stomach to process.

For broader bloating and discomfort, both sources point to dietitian-guided approaches like a structured low-FODMAP elimination diet, done under supervision rather than as a self-directed elimination. There's also emerging discussion of movement modification, meaning pacing physical activity around GI symptoms rather than pushing through them, though this is a general practice recommendation rather than a separately tested intervention in the hEDS population specifically.
