Quick Answer
Vaginal flatus, sometimes called vaginal wind, is air being drawn into the vagina and then released again later, often with a sound that can feel embarrassing but isn’t a sign anything is wrong with your body. A 2025 study following women from pregnancy through to 12 months postpartum found it affects a real, meaningful proportion of women at these check points, and it’s linked to specific, identifiable changes in the pelvic floor after birth, not something you did wrong. Current evidence for exercise-based treatment is actually limited, so it’s genuinely worth an honest assessment rather than assuming pelvic floor exercises alone will resolve it.
If you’ve searched this because it’s happening to you and nobody warned you it could, I want to say plainly: this is a real, recognised postpartum symptom, not something rare or strange, even though it rarely comes up in the “what to expect” conversations before you give birth.
What’s Actually Going On
Vaginal flatus happens because your pelvic floor and vaginal walls move as you change position, during exercise, or during sex. As the pelvic floor lifts and the space inside the vagina changes shape, air can be drawn in, and then it escapes again later when you move, cough, or shift position, sometimes with the sound that gives it away. It isn’t related to bowel gas and isn’t something you’re doing wrong by moving your body normally.
A longitudinal study following women from mid-pregnancy through to 12 months postpartum found vaginal flatus in a genuine, non-trivial proportion of women at both the 3-month and 12-month check points, with the rate actually higher for some groups of women at 12 months than at 3 months, so this isn’t always something that just resolves on its own with time (Macedo et al., 2025, BJOG). The same study found it was more strongly linked to specific anatomical changes after birth, including a partial tear of the levator ani muscle (the main muscle group of your pelvic floor) and a larger genital hiatus, the opening at the base of your pelvic floor, than to any particular type of delivery on its own.
How Is This Different From Bowel Gas?
It’s easy to assume this is connected to digestion, but it genuinely isn’t. Bowel gas comes from your digestive system and exits through the rectum, often linked to what you’ve eaten. Vaginal flatus is entirely mechanical, air moving in and out of a separate space, the vagina, in response to movement and pressure changes, with no connection to diet, gut bacteria, or what you’ve eaten that day. If changing your diet hasn’t made any difference, that’s expected, it was never going to be a diet issue in the first place.
Why This Matters for What You Do Next
Because vaginal flatus is linked to specific, identifiable pelvic floor changes rather than being a vague, unexplainable symptom, it’s genuinely worth having it properly assessed rather than just living with it or assuming it’s a normal, permanent part of having given birth. A pelvic health physiotherapist can check your pelvic floor’s structure and function directly, including whether there’s any muscle avulsion or a wider-than-typical genital hiatus, and build a plan around what they actually find, rather than a generic exercise routine.
I want to be honest here rather than overclaim: the current evidence specifically supporting pelvic floor exercise as a treatment for vaginal flatus itself is limited, this is a genuinely under-researched area, and general pelvic floor training wasn’t designed with this specific symptom in mind. Where there’s more established evidence is for using a pessary, a supportive device fitted by a professional, in cases linked to a wider genital hiatus or prolapse. A cue some pelvic health physiotherapists teach, sometimes called “blow before you go,” a gentle exhale paired with pelvic floor engagement before a position change, may help manage the downward pressure that draws air in, though this is more of a practical management strategy than a proven cure.
In my own work with postnatal clients, this is exactly the kind of symptom I want you to mention rather than quietly manage around, because it often travels alongside other pelvic floor changes, like a sense of heaviness or changes in how intercourse feels, that are worth addressing together through a proper assessment, rather than assuming exercise alone will resolve this particular symptom.
What Can Help Alongside Assessment
Building genuine pelvic floor coordination and strength is still a reasonable, worthwhile thing to do for your overall pelvic health, even though it isn’t a guaranteed fix for vaginal flatus specifically. This is where I’d bring in Hypopressives, which works on the coordination between your diaphragm and pelvic floor rather than isolated squeezing, though it isn’t a substitute for an assessment that identifies what’s specifically going on with your anatomy first. Gentle movement and a graded return to exercise, rather than an abrupt jump back to your pre-pregnancy routine, is not automatically something to avoid, but a generic plan cannot account for your individual recovery, your delivery, or what an assessment finds.
When to Seek Assessment
This guide is educational and cannot diagnose the specific cause of your symptoms. Arrange an assessment with a GP or pelvic health physiotherapist if vaginal flatus is a regular occurrence, if it’s affecting your confidence or intimacy, or if it’s accompanied by other symptoms like heaviness, a bulge, or leakage. There is no need to wait months hoping it settles by itself, especially given the same research found it can still be present, or even more common, a full year after birth.
If you want to understand more about how Hypopressives supports overall pelvic floor coordination, my guide to Hypopressives for a weak pelvic floor goes into that in more depth, and if you’re earlier in recovery, my postnatal recovery pillar is a good place to see the fuller picture of what’s normal and what’s worth flagging.
