Most women know menopause can bring hot flashes or sleep changes. But many don’t realize it also affects something you can’t see — your vaginal microbiome, the natural community of bacteria that helps keep your vagina healthy.
Understanding what happens inside your body can make this stage of life a little less confusing and a lot more empowering.
1. Your Good Bacteria Start to Decline
Throughout your life, your vaginal microbiome shifts and grows.
During your reproductive years, Lactobacillus is the dominant, protective bacteria that help maintain a healthy, low pH.
As estrogen levels fall in menopause, Lactobacillus levels also decline, while other organisms like Gardnerella, Candida, and Prevotella may increase.
This shift can contribute to dryness, irritation, and recurring discomfort.
2. A Higher pH Makes Infections More Common
Lactobacillus helps keep the vaginal environment balanced.
When these good bacteria decrease, vaginal pH rises — which allows less-friendly organisms to thrive.
As a result, postmenopausal women may notice:
- More yeast infections
- Recurring bacterial vaginosis (BV)
- More frequent urinary tract infections (UTIs)
These issues are common during menopause but not something you need to “just live with.”
3. Research Shows Menopause Reduces Key Nutrients Your Microbiome Needs
Lactobacillus survives by feeding on glycogen, a natural nutrient found in vaginal tissues.
After menopause, estrogen decline leads to lower glycogen levels, which makes it harder for good bacteria to thrive.
Research studies show:
- Women with menopause-related vaginal atrophy have significantly lower Lactobacillus diversity than those without atrophy.
- Postmenopausal women consistently show reduced free glycogen, which impacts microbiome health and tissue comfort.
The Bottom Line
Your vaginal microbiome is central to maintaining comfort, moisture, and urinary health. Menopause naturally shifts this balance, but with the right support, you can maintain a healthy microbiome and feel more comfortable through this transition.
