Hypermobility, Ehlers-Danlos Syndrome, and the Pelvic Floor, What to Know for Vaginal Birth

If you’ve been told you’re hypermobile or have Ehlers-Danlos syndrome, it’s natural to wonder how this might affect your pelvic floor and your experience of pregnancy and vaginal birth.

What is hypermobility?

Hypermobility means your joints move more than average due to increased flexibility in your connective tissues. For some, this is simply a normal variation. For others, particularly those with Ehlers-Danlos syndrome (EDS), it reflects a difference in collagen, the protein that provides structure and support to tissues throughout the body.

Because the pelvic floor is made up of muscles and connective tissue, these differences can influence how it functions.

How can this affect the pelvic floor?

People with hypermobility or EDS may be more likely to experience:

• A feeling of heaviness or reduced support

• Stress urinary incontinence (leakage with coughing, sneezing, or exercise)

• Pelvic organ prolapse

This is often due to connective tissues being more elastic, meaning they may not provide the same passive support.

What about vaginal birth?

A common question is whether vaginal birth is safe or advisable.

In most cases, vaginal birth is still a safe and appropriate option. However, there are a few considerations:

• Tissues may stretch more easily, which can be helpful during birth

• But there may also be a slightly increased risk of tearing or pelvic floor symptoms afterwards

• Recovery can sometimes take longer due to how connective tissue heals

This doesn’t mean you should avoid vaginal birth, but it does mean support and planning matter.

How can you prepare?

• Work with a pelvic health physiotherapist during pregnancy

• Focus on pelvic floor strength and coordination, not just relaxation

• Learn how to manage pressure during pushing

• Have a postnatal check to guide your recovery and return to exercise

The key takeaway

Hypermobility and EDS don’t automatically lead to pelvic floor problems, but they can influence how your body responds to pregnancy and birth. With the right support, many women have positive birth experiences and recover well.

If you’re unsure, getting individualised advice can make a big difference to your confidence and outcomes.
