When most people think about the microbiome, they think of the gut. But your bladder has its own microbial community too — and it plays a surprisingly important role in your health, especially during and after menopause.
Yes, your bladder has a microbiome!
The urinary microbiome isn’t as diverse as the gut or even the skin, but it’s still essential. These tiny organisms help maintain bladder function, protect against infections like UTIs, and support your local immune defences. A healthy urinary microbiome is part of what keeps everything running smoothly without you needing to think about it.
But during menopause, that balance can shift.
What happens to the urinary microbiome during menopause?
As oestrogen levels decline, the protective environment of the urinary tract becomes more vulnerable. You may notice more frequent UTIs, discomfort, or just a general sense that “something’s off” — and the microbiome could be part of the puzzle.
Research shows that menopausal women often have:
- Higher levels of Mobiluncus – a type of bacteria linked to infections like bacterial vaginosis (BV).
- Lower levels of Lactobacillus – the ‘good’ bacteria that help keep pH balanced and protect against harmful microbes.
This shift can make the urinary tract more prone to infection, especially when combined with the thinning and dryness of the tissue that often occurs after menopause.
Can probiotics help the urinary microbiome?
There’s growing interest in the use of Lactobacillus-based probiotics to support the urinary microbiome. Some studies suggest that they may help reduce the recurrence of UTIs by keeping uropathogens in check.
That said, probiotics aren’t a silver bullet — and they may not be suitable for everyone. It’s always best to look at the bigger picture: hydration, toileting habits, hormonal changes, and any relevant medical history.
Final thoughts
If you’ve found yourself dealing with more UTIs or bladder issues since menopause, know that you’re not alone — and it’s not all in your head. Your urinary microbiome may be playing a bigger role than you realised.
There are practical steps you can take, and targeted support that can make a real difference.
