Could Low Estrogen Be Causing Your UTIs?

If you suddenly started getting urinary tract infections in your 40s or 50s—even though UTIs were never much of a problem before—there may be another piece of the puzzle worth looking at: estrogen.

Most women associate declining estrogen with hot flashes, night sweats and changes in their menstrual cycle. But estrogen also plays an important role in the health of the vaginal and urinary tissues.

As estrogen begins to fluctuate and eventually decline during perimenopause and menopause, changes can occur in the vagina, vulva, urethra and bladder. For some women, one result is an increase in urinary discomfort and recurrent UTIs.

So if it feels like UTIs suddenly became a regular visitor you definitely did not invite, your hormones may be part of the conversation.

What Does Estrogen Have to Do With Your Urinary Tract?

Quite a bit, actually.

Estrogen receptors are present throughout tissues of the vagina and lower urinary tract. Estrogen helps support the thickness, elasticity, blood flow and moisture of these tissues.

Estrogen also helps maintain a vaginal environment that supports beneficial Lactobacillus bacteria. These bacteria help keep the vaginal pH acidic and make the environment less hospitable to potentially harmful bacteria.

When estrogen declines, vaginal tissues can become thinner and drier, vaginal pH can rise, and the vaginal microbiome can change.

Those changes may make it easier for bacteria associated with UTIs to colonize the area around the urethra and potentially travel into the urinary tract.

Why Recurrent UTIs May Become More Common During Perimenopause and Menopause

This collection of changes is often referred to as genitourinary syndrome of menopause, or GSM.

Despite the name, these symptoms can begin during the menopausal transition and may include much more than vaginal dryness.

Women may experience:

• Recurrent urinary tract infections

• Burning with urination

• Increased urinary frequency

• Urinary urgency

• Vaginal dryness

• Vaginal burning or irritation

• Pain or discomfort during intercourse

• Changes in vaginal discharge or sensation

Sometimes women repeatedly treat what appears to be a UTI without realizing that hormonal changes may also be contributing to their urinary symptoms.

That's an important distinction because not every episode of urinary burning, urgency or frequency is necessarily caused by a bacterial infection.

Is It a UTI—or Low Estrogen?

This is where testing matters.

Symptoms such as burning, urgency and frequency can occur with a UTI, but similar symptoms can also occur with genitourinary changes related to declining estrogen.

If you're experiencing recurrent symptoms, particularly if urine cultures are repeatedly negative, it's worth discussing the possibility of GSM with your healthcare provider rather than automatically assuming every episode is another infection.

On the other hand, a true UTI shouldn't simply be attributed to hormones. Urinary infections can progress and require appropriate medical treatment.

The goal is to figure out why the symptoms keep happening, not just assume every urinary symptom has the same cause.

The Vaginal Microbiome Matters Too

We hear a lot about the gut microbiome, but the vaginal microbiome deserves some attention too.

In many healthy premenopausal women, Lactobacillus species dominate the vaginal microbiome. These beneficial bacteria produce lactic acid, helping maintain an acidic vaginal environment.

Declining estrogen can reduce the conditions that favor Lactobacillus and contribute to changes in vaginal pH and microbial balance.

That means recurrent UTIs during perimenopause and menopause may involve more than simply encountering the “wrong” bacteria.

The surrounding environment has changed too.

This is one reason I like looking at the bigger picture when symptoms suddenly appear during the menopausal transition.

What About Vaginal Estrogen?

For appropriate patients, low-dose vaginal estrogen is one option clinicians may discuss for genitourinary symptoms and recurrent UTIs associated with menopause.

Unlike systemic hormone therapy, local vaginal estrogen is intended primarily to act on vaginal and urinary tissues. It is available in several forms, including creams, tablets or inserts, and vaginal rings.

Research and clinical guidelines support vaginal estrogen as an option for reducing recurrent UTIs in peri- and postmenopausal women when there are no contraindications.

Whether it's appropriate for you is an individual medical decision, particularly if you have a history of hormone-sensitive cancer or other medical considerations. That's a conversation to have with your gynecologist or other qualified healthcare provider.

What Else Should Be Considered With Recurrent UTIs?

Low estrogen can be an important piece of the puzzle, but it isn't the only possible contributor.

When someone is dealing with recurrent UTIs, I also want to think about the broader picture, including hydration, sexual activity, pelvic floor health, blood sugar regulation, vaginal health, medications, bowel health and whether the infections have actually been confirmed with urine testing.

In some cases, persistent urinary symptoms may have another explanation entirely.

This is why repeatedly treating symptoms without asking why they keep returning can leave an important part of the picture unexplored.

A Chinese Medicine Perspective

Chinese medicine looks at recurrent urinary symptoms somewhat differently.

Rather than treating every patient with the same approach, we look at the overall pattern.

Acute urinary burning, urgency and frequency may resemble a Damp-Heat pattern, while recurrent urinary problems—particularly in women going through menopause—may occur alongside patterns involving Kidney deficiency, Yin deficiency or other underlying imbalances.

A woman experiencing urinary symptoms along with night sweats, vaginal dryness, insomnia and feeling hot at night presents a very different pattern from someone experiencing urinary symptoms with significant fatigue, feeling cold and frequent nighttime urination.

That's why Chinese medicine treatment is individualized rather than based on the symptom of “UTI” alone.

Acupuncture and Chinese herbal medicine may be used as supportive therapies based on the individual's overall pattern, while suspected bacterial UTIs still need appropriate medical evaluation.

Dr. Stephanie's Tip: If UTIs suddenly started becoming a problem around the same time your periods became irregular, hot flashes appeared, sleep changed or vaginal dryness developed, don't look at those symptoms as completely unrelated events.

Bring up the timing with your healthcare provider.

Your urinary tract doesn't exist separately from your hormonal system, and declining estrogen may be an important part of understanding why things have changed.

When to Seek Medical Care

If you think you have a UTI, especially if you have significant pain, blood in the urine, fever, chills, nausea, vomiting, back or flank pain, or worsening symptoms, seek medical care promptly.

These symptoms may indicate a more serious infection involving the kidneys.

Recurrent UTIs also deserve proper evaluation rather than repeated self-treatment.

Could Your Hormones Be Part of the Picture?

If you're in perimenopause or menopause and suddenly dealing with recurrent UTIs, urinary urgency, burning or vaginal dryness, declining estrogen may be one piece of the puzzle.

The hormonal changes happening during this stage of life affect much more than your menstrual cycle.

Understanding those connections can help you have a more productive conversation with your healthcare provider and find an approach that addresses what's actually contributing to your symptoms.

FAQ

Can low estrogen cause recurrent UTIs?

Declining estrogen can contribute to changes in vaginal and urinary tissues and the vaginal microbiome that may increase susceptibility to recurrent UTIs, particularly during and after the menopausal transition.

Why am I suddenly getting UTIs during perimenopause?

Hormonal changes may be one contributor. As estrogen fluctuates and declines, vaginal tissues, pH and the vaginal microbiome can change. Other causes of recurrent UTIs should also be evaluated.

Can low estrogen feel like a UTI?

It can contribute to urinary burning, urgency and frequency that may resemble UTI symptoms. This is one reason urine testing can be important, particularly when symptoms keep returning.

What is genitourinary syndrome of menopause?

Genitourinary syndrome of menopause, or GSM, describes vaginal, vulvar, sexual and urinary changes associated with declining estrogen and other sex steroids during menopause.

Does vaginal estrogen help recurrent UTIs?

For appropriate peri- and postmenopausal patients, clinicians may recommend low-dose vaginal estrogen to address genitourinary changes and help reduce recurrent UTIs. Whether it's appropriate depends on an individual's medical history.

At New Direction Natural Medicine in Altamonte Springs, Florida, I work with women throughout perimenopause and menopause using acupuncture, Chinese medicine, functional medicine and individualized nutrition to look at the bigger picture behind changing symptoms.

If your body suddenly seems to be following a completely different instruction manual than it did five years ago, it may be time to start looking at the connections.
