A friend called me a few months back, scared and exhausted. Her mom, who’s in her 60s, had just spent four nights in the hospital. What started as symptoms she didn’t even recognize as a UTI escalated so rapidly that she landed in the ER. She was dangerously close to becoming septic.
When my friend started telling me about her mom’s history, the pattern became clear. Her mom had been dealing with recurrent UTIs for the past year, and no one, not even her OB-GYN, had mentioned hormone fluctuation as a possible cause.
It wasn’t until we were talking, not only as her friend but also as a pelvic floor therapist, that the hormone connection came up. She immediately called her mom to tell her about low estrogen potentially being the culprit for her recurring UTIs. Now her mom is on hormone replacement therapy, and the difference has been remarkable.
In the last few years, I am seeing more and more Obgyns and primary care doctors prescribing hormone replacement therapy but unfortunately this kind of scenario is still quite common. The primary urinary-related cause for women entering nursing homes is unmanageable urinary incontinence (UI), often stemming from frequent UTIs and contributing to dementia. We can prevent this from happening with some basic knowledge about what the latest research is teaching us about women’s hormones and urinary control.
Are Frequent UTIs a Symptom of Perimenopause or Menopause?
Yes, and here’s why it matters so much. When you’re getting UTI after UTI during perimenopause or menopause, the natural response from healthcare providers is to prescribe antibiotics. You take them, feel better for a while, and then boom. Another infection. This cycle can continue for months or even years.
But here’s what often gets missed. If you’re experiencing recurrent UTIs during perimenopause or menopause, the real driver of those infections might not be bacteria at all. It might be your fluctuating and declining estrogen levels.
And here’s the crucial part. Perimenopause is actually the ideal time to address this issue.
Recent research presented at The Menopause Society’s 2025 Annual Meeting analyzed data from over 120 million patient records and found that women who started estrogen therapy during perimenopause (at least 10 years before menopause) had approximately 60% lower odds of developing breast cancer, heart attack, and stroke compared to those who started after menopause or never used hormones.
Is Low Estrogen the Cause of Recurring UTIs
You might be wondering, is low estrogen the cause of my recurring UTIs? The connection is actually pretty remarkable.
During your reproductive years, estrogen helps maintain healthy levels of protective bacteria called Lactobacillus in your vagina and urinary tract. These beneficial bacteria create an acidic environment that makes it hard for harmful bacteria like E. coli to take hold and cause infection.
Estrogen does this by increasing glycogen in the cells lining your vagina. Lactobacillus feeds on this glycogen and produces lactic acid. This keeps your vaginal pH around 3.5 to 4.5, which is protective against infection.
When estrogen starts fluctuating and declining during perimenopause, several things happen at once:
- Less glycogen means less food for Lactobacillus
- Lactobacillus levels begin to decline
- Your vaginal pH starts becoming less acidic and more alkaline
- Harmful bacteria have an easier time multiplying
- Your risk of recurrent UTIs increases
This process often begins in perimenopause and worsens through menopause. Research shows that recurrent UTIs increase from 19-36% in premenopausal women to 55% after menopause. That’s a significant jump.
The key insight? Catching this pattern early during perimenopause allows for intervention before years of recurrent infections take their toll.
The Research on Estrogen for Recurrent UTI Prevention
Multiple studies have demonstrated that vaginal estrogen therapy significantly reduces recurrent UTIs in perimenopausal and postmenopausal women.
A large 2023 study published in the American Journal of Obstetrics and Gynecology tracked over 5,600 women using vaginal estrogen. Women reduced their UTI frequency by 51.9%, dropping from an average of 3.9 infections per year down to 1.8. Other research shows vaginal estrogen can reduce infections from about 5 per year down to just 0.5 to 2 annually.
The American Urological Association now includes vaginal estrogen in their 2019 guidelines, specifically recommending it for peri- and postmenopausal women with recurrent UTIs.
What makes vaginal estrogen particularly effective is how it works. Unlike antibiotics that temporarily kill bacteria, vaginal estrogen restores the protective environment that prevents infections from taking hold. It brings back helpful Lactobacillus bacteria, lowers vaginal pH, and improves tissue health.
Recurrent UTIs and Low Estrogen: Why Doctors Aren’t Making the Connection
Despite strong evidence, many women spend months or years cycling through antibiotics without anyone mentioning hormones as a cause. My friend’s mom is a perfect example. In her 20 years of experiencing perimenopause and now postmenopause, she never had a single conversation about hormones with any doctor, until my friend was desperate for answers when a severe infection nearly sent her mom into sepsis.
Why does this happen? Some providers simply aren’t aware of the hormone connection. Others might not be up to date on the latest research. And sometimes, the focus is so narrowly on treating the acute infection that the underlying cause gets missed.
This is where I see a real opportunity for change, especially here in Washington DC where we have access to excellent medical care. Women deserve providers who look at the whole picture.
How We Screen for Hormone Issues During Perimenopause
As a pelvic health therapist, I’m in a unique position to spot this pattern early. When women in their 40s and 50s (sometimes even in their 30s) come to me with any of these symptoms, I always ask about hormones:
- Recurrent UTIs
- Urinary urgency or frequency
- Pain during intimacy
If someone reports recurrent UTIs during perimenopause, I specifically ask if any doctor has discussed hormone therapy with them. Most of the time, the answer is no.
This gives me an opportunity to educate them about the connection and encourage them to have that conversation with their gynecologist or primary care provider. I can explain the difference between local vaginal hormones and systemic hormone replacement therapy.
When women do start hormone treatment during perimenopause, whether it’s local vaginal estrogen or systemic hormone replacement, I often see a huge difference in their pelvic floor function and symptoms. The improvement can be remarkable.
Starting treatment during perimenopause, rather than waiting until after menopause, often leads to better outcomes and prevents years of unnecessary suffering.
Understanding the Difference Between Local and Systemic Hormones
It’s important to understand that there are two main types of hormone therapy, and they serve different purposes:
Local vaginal estrogen therapy delivers a low dose of estrogen directly to the vaginal and urinary tissues. Very little, if any, gets into your bloodstream. This type of therapy is specifically effective for genitourinary symptoms like recurrent UTIs, vaginal dryness, and painful intercourse. It’s available as creams, tablets, suppositories, or vaginal rings.
Systemic hormone replacement therapy delivers hormones throughout your body via pills, patches, sprays, gels, or a vaginal ring. These are absorbed into the bloodstream at higher levels and have widespread effects. Systemic therapy is effective for symptoms like hot flashes and helps protect bones. It also carries different risks, such as blood clots and, with long-term use, a potential increased risk of breast cancer.
The ideal time to start? During perimenopause, when estrogen levels first begin to fluctuate. Early intervention can prevent the cascade of changes that lead to recurrent infections.
Recent FDA changes have also made vaginal estrogen more accessible. In November 2025, the FDA removed the black box warning from hormone therapy products. You can read more about this historic change here.
When to Talk to Your Doctor About Perimenopause and UTIs
If you’ve had two or more UTIs in the past six months, or three or more in the past year, you meet the definition of recurrent UTIs. This is the time to ask about hormone screening, especially if you’re in your 30s, 40s, or 50s.
Questions to ask your healthcare provider:
- Could perimenopause and low estrogen be the cause of my recurring UTIs?
- Would I be a good candidate for hormone replacement therapy?
- Which type of hormone therapy makes more sense for my situation, vaginal estrogen or systemic hormone replacement?
- Are there any reasons I shouldn’t use vaginal estrogen?
Don’t accept “this is just something that happens with age” as an answer. Yes, frequent UTIs are a symptom of perimenopause and menopause for many women, but that doesn’t mean you have to live with them. Treatment exists, and starting early matters.
When It’s Not Just Low Estrogen As the Cause of Recurring UTIs
While low estrogen is a major factor in recurrent UTIs during perimenopause and menopause, it’s not always the only cause. Some cases involve bacteria like Ureaplasma that don’t show up on standard testing. Other times, scar tissue from previous infections or surgeries creates an environment where bacteria thrive.
Understanding the full picture of what can cause recurrent UTIs helps you and your healthcare providers find the right solution. Learn more about the complex factors behind recurrent UTIs in this post about Ureaplasma and the infection-scar tissue connection.
Getting Care During Perimenopause
The bottom line is this, if you’re dealing with recurrent UTIs during perimenopause or menopause, you deserve providers who look beyond just prescribing another round of antibiotics. You deserve someone who asks about your hormones, screens for underlying causes, and treats you as a whole person rather than a collection of symptoms.
