You’ve treated it, it goes away, and then it’s back. Another round of the same burning, itching, or unusual discharge — and you’re starting to wonder if something is seriously wrong with you. It’s not. But there is something real happening, and it almost certainly has to do with menopause vaginal infections that your doctor may never have connected for you.
Recurring vaginal infections — whether yeast infections, bacterial vaginosis (BV), or urinary tract infections (UTIs) that keep creeping back — become significantly more common around perimenopause and menopause. This is not bad luck or poor hygiene. It’s biology. And once you understand what’s shifted in your body, you can start doing something about it.
What’s Actually Happening: Your Vaginal Garden Is Changing
Think of your vaginal microbiome as a garden. A healthy garden has one dominant, thriving plant — in this case, a type of bacteria called Lactobacillus — that keeps the soil acidic enough to stop weeds (harmful bacteria and fungi) from taking hold. That garden runs beautifully for decades.
Then estrogen begins to fall. Estrogen is what feeds the lining of the vaginal walls, keeping them thick and rich in glycogen — the very substance Lactobacillus feeds on. Less estrogen means less glycogen, which means the dominant protective bacteria start to thin out. The soil becomes less acidic, the pH rises, and suddenly the garden is open to anything that wants to grow there: yeast, BV-causing bacteria, and the organisms that cause recurring UTIs.
According to the Menopause Society, this whole cluster of changes — vaginal dryness, thinning tissues, altered pH, and increased infection vulnerability — falls under a condition called Genitourinary Syndrome of Menopause, or GSM. It affects a significant proportion of women after menopause, and yet most are never told about it.
Why Infections Keep Coming Back
Treating a single infection without addressing the underlying shift in your vaginal environment is a bit like pulling one weed while leaving the soil conditions that grow them. The infection clears. The conditions haven’t changed. Another infection follows.
Yeast infections
Candida yeast thrives in a less acidic environment. If your pH has risen and your Lactobacillus colonies are thin, yeast has much less competition. Some women who never had a yeast infection in their lives suddenly get them repeatedly in their 40s or 50s.
Bacterial vaginosis
BV happens when the balance tips too far toward anaerobic bacteria. The NHS notes that BV is not sexually transmitted — it’s a disruption of natural balance. The fishy odour and grey-white discharge are distressing and frequently misunderstood. In perimenopausal and menopausal women, BV can recur persistently because the root imbalance — low estrogen, low Lactobacillus — hasn’t been treated.
Recurrent UTIs
Thinner, drier vaginal and urethral tissues are more easily irritated and less able to resist bacteria travelling to the bladder. This is why UTIs can suddenly become a recurring problem for women who rarely had them before. If you’ve had more than two UTIs in six months, it’s worth talking to a clinician specifically about GSM as a contributing cause.
What It’s Often Mistaken For
Many women are told — repeatedly — that they simply need to be more careful about hygiene, or that stress is causing their symptoms, or that they should stop wearing certain underwear. Some are given yet another short course of antibiotics or antifungals without anyone asking why the infections keep returning.
If you recognise yourself in this pattern, you are not imagining it and it is not your fault. The missing piece is almost always hormonal. You might also find it useful to read about vaginal dryness and GSM in menopause, which often goes hand-in-hand with recurring infections.
What Actually Helps
The good news: there are well-evidenced options that address the root cause, not just the latest flare-up.
Lifestyle measures
- Avoid vaginal douching and scented products. These further disrupt the microbiome. Warm water is enough for external cleaning.
- Breathable underwear. Cotton reduces moisture that encourages yeast. Genuinely helpful — just not the whole answer.
- Vaginal moisturisers. Non-hormonal, pH-balanced vaginal moisturisers used regularly (not just during intercourse) can help maintain tissue moisture and a more protective environment. Look for products with a pH of around 3.8–4.5.
- Probiotics. Evidence is still emerging, but some Lactobacillus-containing vaginal or oral probiotics show promise in supporting microbiome balance. Ask your clinician about options.
Non-hormonal medical options
- Topical boric acid suppositories are used in some countries for recurrent BV and yeast, though they are not suitable for everyone — discuss with a healthcare professional before trying.
- Targeted antibiotic or antifungal treatment may still be needed for active infections, but should be paired with a longer-term plan to address the microbiome.
Hormonal options
- Vaginal estrogen is the most evidence-backed treatment for GSM and its associated recurring infections. It is applied locally (cream, ring, or pessary) and is absorbed very minimally into the bloodstream. The Menopause Society and NICE both support its long-term use as safe and effective for most women. It works by restoring tissue thickness, lowering vaginal pH, and feeding the Lactobacillus colonies that protect you.
- Systemic HRT addresses the broader hormonal picture and may also reduce GSM symptoms, though vaginal estrogen is often added specifically for local tissue health.
Understanding your full range of hormonal options is worth exploring — you can read more about how HRT works and what to expect and about the broader symptoms of perimenopause that often go unrecognised.
When to See a Doctor
Please don’t keep cycling through over-the-counter treatments alone. See a healthcare professional if:
- You’ve had two or more yeast infections, BV episodes, or UTIs in the past six months.
- Symptoms haven’t cleared fully after treatment, or return within a few weeks.
- You have unusual bleeding, pelvic pain, or discharge with a strong or unusual odour.
- You’re struggling with vaginal dryness, pain during sex, or urinary symptoms alongside the infections — these point strongly to GSM.
When you go, you can say: “I’m getting recurring infections and I’d like to talk about whether GSM or hormonal changes could be a factor, and whether vaginal estrogen is appropriate for me.” You deserve a clinician who takes this seriously.
Frequently Asked Questions
Can menopause really cause recurring yeast infections?
Yes. Falling estrogen raises vaginal pH and reduces the protective Lactobacillus bacteria that keep yeast in check. Many women who rarely had yeast infections before find them recurring in perimenopause and beyond. This is a recognised part of Genitourinary Syndrome of Menopause, not a coincidence.
Is vaginal estrogen safe to use long-term?
For most women, yes. The Menopause Society and NICE both support long-term use of local vaginal estrogen. It is absorbed minimally into the bloodstream. Your clinician can advise based on your personal health history, including if you have a history of hormone-sensitive conditions.
How is BV different from a yeast infection?
BV is caused by an overgrowth of anaerobic bacteria and typically causes a thin, greyish discharge with a fishy odour. A yeast infection usually causes thick white discharge, itching, and soreness. Both can recur more frequently after menopause due to the same underlying microbiome disruption.
Will probiotics fix recurring vaginal infections?
Probiotics may support microbiome balance, and research is promising, but they’re unlikely to be enough on their own if the underlying cause is low estrogen. They work best as part of a broader plan that may include vaginal estrogen and lifestyle measures, discussed with your clinician.
Why do I keep getting UTIs after menopause?
Estrogen loss causes the tissues of the vagina and urethra to thin and dry, making them more vulnerable to bacteria reaching the bladder. Recurrent UTIs in this life stage are frequently linked to GSM. Vaginal estrogen can significantly reduce their frequency for many women.
