The intimate side of menopause: Genitourinary Health

There are a cluster of symptoms that affects the majority of women during perimenopause and beyond - yet many women are not comfortable discussing it and therefore not being supported . 

Genitourinary symptoms are common, affecting 50-70% of women through this transition and beyond. Changes to the vagina, vulva, bladder, and pelvic floor that can quietly erode comfort, confidence, and quality of life. Unlike other menopause symptoms like hot flushes, which tend to ease over time, genitourinary symptoms often persist and can even worsen without support as women age.

The good news? There is a lot you can do.

Why This Happens: It Starts With Estrogen

Estrogen is not just a reproductive hormone - it is a tissue architect. It maintains the health, moisture, and structural integrity of the entire genitourinary tract. When estrogen levels begin to fluctuate and decline in perimenopause, this environment in this region also changes.

Tissue changes. Estrogen maintains tissue tone. As levels drop, the vaginal walls become thinner, drier, and less elastic. The vulva may lose fullness, the labia majora and clitoral hood can contract, and the vaginal opening may narrow over time. Tissue that was once resilient becomes fragile and prone to irritation, tearing, and discomfort during sex.

Microbiome shifts. Healthy estrogen levels support a vaginal microbiome dominated by Lactobacillus species, which produce lactic acid and keep vaginal pH low (around 3.8–4.5). As estrogen declines, Lactobacillus populations fall, pH rises above 4.5, and the environment becomes more alkaline. This shift can increase vulnerability to bacterial vaginosis and UTIs. 

Sexual symptoms Dyspareunia (pain during sex), reduced lubrication, post-coital bleeding, decreased arousal, orgasm and desire, loss of libido, and dysorgasmia are all recognised. Vaginal dryness and dyspareunia are the two most commonly reported symptoms overall.

Bladder and pelvic floor effects. The urethra and bladder are estrogen-sensitive tissues too. As estrogen declines, urethral tissue thins, bladder urgency and frequency increase, and stress incontinence (leaking with coughing, sneezing, or exercise) becomes more common. Pelvic organ prolapse is also associated with pelvic floor weakening in this stage of life.

Sensory changes. Some women notice altered sensation in the clitoris and vulva, either hypersensitivity or reduced feeling,  which can significantly impact sexual pleasure and intimacy.

This constellation of symptoms is now formally recognised as Genitourinary Syndrome of Menopause (GSM) - a term that reflects how interconnected these changes are.

What Can Help

Localised Topical Vaginal Estrogen

This is the most evidence-based intervention available, and it is significantly underused. Unlike systemic hormone therapy, vaginal estrogen works locally. It restores tissue health, supports the vaginal microbiome, reduces recurrent UTIs, and improves bladder symptoms without substantial systemic absorption. Current evidence supports its long-term use, and it is considered safe for most women, including many breast cancer survivors (in consultation with their oncologist). If this has been recommended to you, or you are curious about it, it is worth a direct conversation with your GP or gynaecologist.

Phytoestrogens

Soy isoflavones and flaxseed lignans act as weak estrogen modulators. Research suggests they can offer modest support for vaginal tissue health and symptom relief, particularly in women who either cannot or prefer not to use hormonal options. These can also be consumed alongside HRT and vaginal estrogen support. Some evidence shows that phytoestrogens can improve the moisture of tissue. Here is a recipe you can try: Flaxseed loaf

I simply add 1-2 tbsp to my oats everymorning:)

Targeted Probiotic Support

Specific Lactobacillus strains,  including L. rhamnosus, L. reuteri, and L. crispatus,  have emerging evidence for supporting vaginal microbiome health. Both oral and intravaginal delivery have been studied. If you are dealing with recurrent infections or dysbiosis, this is an area where personalised probiotic support can make a real difference. Working with a trusted practitioner who can look more closely at your genitourinary microbiome and provide personalised support can be helpful.

Pelvic Floor Rehabilitation

For bladder symptoms, prolapse, and pelvic floor weakening, working with a pelvic floor physiotherapist is one of the most effective things you can do. This is specialised, hands-on care (not just Kegels). A physiotherapist can assess your specific patterns of tension or weakness and provide a tailored rehabilitation plan.

Moisturisers and Lubricants

Non-hormonal vaginal moisturisers used regularly (not just at sexual activity) can help maintain tissue hydration. Look for products that are pH-balanced and free from glycerine, parabens, and fragrances. This is a supportive measure, not a replacement for addressing the underlying hormonal shift but it can meaningfully improve day-to-day comfort.

Nutrition and the Gut–Vaginal Axis

This is an area that is easy to overlook, but it matters more than most people realise. What you eat directly shapes your gut microbiome and your gut microbiome has a measurable influence on estrogen metabolism, systemic inflammation, and the health of the vaginal environment.

The connection runs through the estrobolome: the collection of gut bacteria that produce an enzyme called beta-glucuronidase, which deconjugates estrogen in the gut and allows it to be reabsorbed into circulation. A well-nourished, diverse gut microbiome helps maintain this recycling process, supporting circulating estrogen levels even as ovarian production declines. A disrupted gut microbiome can reduce estrobolome activity, accelerating the drop in bioavailable estrogen.

General guidelines to support your gut microbiome:

Include prebiotic fibre - feeding the right bacteria

Prebiotics are non-digestible fibres that selectively feed beneficial bacteria, particularly Lactobacillus and Bifidobacterium species. Two that are worth knowing about specifically:

Galactooligosaccharides (GOS) and fructooligosaccharides (FOS) have both been studied for their ability to stimulate vaginal Lactobacillus populations - not just gut bacteria. Research has shown these compounds can directly support Lactobacillus growth in the vaginal environment, making them particularly relevant for genitourinary health rather than gut health alone. FOS and GOS are found in foods like leeks, onions, garlic, asparagus, legumes, and chicory root, and are also available in supplement form. 

A diverse, fibre-rich diet more broadly supports the gut microbial diversity that underpins estrobolome function. Greater microbial diversity has been positively associated with improved estrogen regulation during perimenopause.

Polyphenols - prebiotic-like and anti-inflammatory

Polyphenols are plant compounds found in berries, pomegranate, green tea, dark chocolate, walnuts, apples, red onion, olive oil, and more. They act as prebiotic-like substrates, meaning they selectively feed beneficial bacteria including Lactobacillus and Bifidobacterium while inhibiting pathogenic species. Dietary polyphenols contribute to intestinal health by preserving microbial balance through stimulation of beneficial bacteria and inhibition of pathogenic bacteria. They also support the cells that create a healthy barrier in our mucous membranes as well as reduce inflammation and oxidation. 

Fermented foods

Fermented foods deliver live bacteria directly to the gut and support microbial diversity. Aim to include at least one serve daily: natural yoghurt (with live cultures), kefir, miso, tempeh, sauerkraut, or kimchi.

Practical nutrition foundation priorities

Rather than a supplement-first approach, a dietary foundation matters. Ensure you are getting enough fibre in general. Prioritise a diverse range of vegetables and fruits (aiming for 30+ different plant foods per week), legumes and pulses as regular staples, fermented foods such as kefir, yoghurt, miso, and kimchi to introduce live cultures, and extra-virgin olive oil, berries, and green tea as daily polyphenol sources. Reduce ultra-processed foods, which are consistently associated with lower microbial diversity and higher systemic inflammation.

A Note on Normalisation

Too many women are are not talking about the genitourinary symptoms they are experiencing. They are common and they are something you simply have to accept or be embarrassed about. They are physiological changes with real mechanisms, and they respond to targeted support.

If any of this resonates with your experience, it is worth bringing it into a clinical conversation with a trusted qualified practitioner. You deserve care that takes the full picture seriously.
