Pelvic Organ Prolapse and hEDS/Hypermobility: What the Research Shows
We're not medical professionals. This page is a summary of what's been published on pelvic organ prolapse in hEDS, put together so you can bring the actual studies to a gynecologist rather than a secondhand claim.
This is one of the places where the research doesn't agree yet, and we think that's worth saying plainly rather than smoothing over. Two studies, decades apart, point in different directions.
Does Hypermobility Cause Pelvic Organ Prolapse? The Original Study
In 1996, McIntosh and colleagues studied 46 people with EDS and looked for a relationship between prolapse and joint hypermobility scores. They didn't find one. Even though the EDS group in the study scored higher on hypermobility measures than comparison groups, prolapse rates weren't significantly associated with those scores. That study is now 30 years old and small, but it was a controlled comparison, which carries real weight.
A Newer Review Challenges the No-Link Finding
A narrative review published in January 2026 in the European Journal of Obstetrics and Gynecology and Reproductive Biology, covering literature through September 2025, reported that prolapse affects an estimated 29 to 75 percent of EDS cases across the studies it pulled together, and described a more than twofold increased risk overall.
That's a striking range, and it directly contradicts the 1996 finding. It's also a different, generally weaker form of evidence than one larger controlled trial, since a narrative review pools many small, varied studies. It can surface a real pattern, but it can also inherit the biases and inconsistencies of whatever studies it included.
What's Resolved and What's Still Unclear
We're not going to tell you which of these two findings is right, because the evidence doesn't let us. What can be said honestly is that the question is open, and that a 30-year-old controlled study and a 2026 pooled review disagree on the basic direction of the relationship.
One gap worth naming on its own: there's no data yet on whether prolapse risk in hEDS differs by parity, meaning whether having given birth changes the picture. If you've had children and are wondering whether that specifically raises your risk, the honest answer right now is that nobody has studied it.
What to do with this
If you're noticing symptoms of prolapse, such as pressure, a sense of bulging or heaviness, or changes in bladder or bowel function, that's a reason to see a gynecologist or urogynecologist regardless of what the population-level statistics say about hEDS. Individual symptoms warrant individual evaluation.
Pelvic-floor physical therapy is a reasonable, low-risk step to ask about whether or not the underlying hEDS connection turns out to be as strong as the 2026 review suggests. Bring both studies to the conversation if you want your provider's read on where the evidence currently stands.
