Vaginal and urinary changes during perimenopause and menopause are extremely common, yet many women still feel unsure, embarrassed, or uncertain about what is normal and what is treatable. These symptoms have clear biological explanations rooted in changing hormone levels, particularly falling oestrogen. The good news? These changes are highly treatable, and early intervention can dramatically improve comfort, sexual wellbeing, and bladder health.
This guide breaks down the science in a friendly, practical way so you can better understand what is happening, feel confident talking about it, and know when and how to seek help.
Why Vaginal Health Changes with Age
Oestrogen plays a critical role in vaginal and urinary wellbeing. Throughout our reproductive years, healthy oestrogen levels keep the vaginal lining thick, elastic, well lubricated, and rich in superficial cells that shed regularly. As these cells break down, they release glycogen, which feeds the vagina’s protective bacteria - Lactobacillus species. These bacteria, in turn, produce lactic acid to keep vaginal pH low (~3.5–4.5), creating a natural shield against infection.
As oestrogen levels decline in perimenopause and menopause, these natural defences weaken. The result is a cluster of symptoms now called Genitourinary Syndrome of Menopause (GSM) - dryness, irritation, pain with sex, recurrent UTIs, and changes in vaginal discharge.
What a Healthy Vagina Does Naturally
A well oestrogenised vagina is a delicately balanced ecosystem:
This elegant system works best with minimal interference. Douching, perfumed washes, and internal cleansers disrupt pH and the microbiome, raising infection risk. The vagina is self-cleaning — the vulva (external area) only needs gentle washing with a mild, pH balanced fragrance-free product or an ointment-based emollient.
When Oestrogen Falls: Understanding Vaginal Dysbiosis
When oestrogen drops, either gradually during perimenopause or suddenly in other low oestrogen states, several things happen:
- The vaginal lining thins.
- Superficial cell numbers fall, sometimes to under 10% of what is seen in a healthy, oestrogen rich vagina.
- Glycogen levels fall, so Lactobacillus levels fall too.
- The vaginal pH rises (>5), becoming less acidic.
- Other microbes — Gardnerella vaginalis (causing Bacterial Vaginosis), anaerobes, and uropathogens — can take over.
This shift is known as vaginal dysbiosis.
Most importantly: these symptoms often mimic thrush yet is not caused by Candida. Itching, burning, discharge changes, and soreness may lead women to repeatedly self-treat with antifungals. But in midlife, true Candida infection becomes less common: postmenopausal prevalence is around 3–7% and falls further with age.
This means that if “thrush treatment” only helps temporarily, the underlying issue is hormonal, not fungal.
Not Just Perimenopause and Menopause: Other Low Oestrogen States
Low oestrogen is not limited to menopause. Several life stages and medical situations can create a similar hormonal environment:
Postpartum & Breastfeeding
Breastfeeding keeps prolactin high, which suppresses ovarian oestrogen. Systematic review data show:
Surgical Menopause & Antioestrogen Medications
Women undergoing ovary removal or taking anti oestrogen therapies (e.g., for breast cancer) often experience abrupt, severe GSM symptoms.
Weight related or stress related hypothalamic suppression
Significant weight loss, extreme exercise, or stress can suppress ovulation and cause low oestrogen states resembling GSM.
Common Symptoms You May Notice
Changes can affect the vulva, vagina, pelvic floor, bladder, and sexual function. Symptoms include:
Many women assume these issues are “just part of ageing,” yet GSM is highly treatable and often reversible with the right care.
The Microbiome and Bladder Connection
The vaginal and lower urinary tract share the same embryological origin and respond similarly to hormonal change. When lactobacilli decline:
Studies show vaginal oestrogen can reduce recurrent UTIs by up to 50% by restoring lactobacilli and lowering vaginal pH.
Dryness, Intimacy and Pain with Sex
Dryness and thinning of vaginal tissue can make sex uncomfortable, even painful. This is one of the most distressing parts of GSM for many women — but it is very treatable.
Lubricants vs Moisturisers
If pain persists despite using moisturiser and lubricant, vaginal oestrogen or pelvic floor physiotherapy can make a transformative difference.
Treatments That Work (UK Context)
First line for mild symptoms- Regular vaginal moisturiser
- Appropriate lubricant during sex
- Local (Vaginal) Oestrogen: Gold Standard for Persistent Symptoms
- Rebuilds the vaginal lining
- Restores superficial cells
- Lowers pH
- Increases lactobacilli
- Improves lubrication and comfort
- Vaginal DHEA (prasterone) improves dyspareunia and vaginal tissue health
- Ospemifene is an oral SERM useful for painful sex when oestrogen is not suitable
- Systemic HRT treats whole-body menopausal symptoms (e.g., flushes).
- Local oestrogen specifically treats GSM.
- Many women on systemic HRT still need an additional local product. Early treatment prevents progression, improves sexual comfort, reduces UTIs, and restores confidence.
- Avoid douching or perfumed washes
- Wear breathable underwear
- Change out of wet clothing quickly such as after working out or any urine leakages
- Use gentle, unscented vulval products
- Choose lubricants designed for sensitive tissue (water or silicone based)
- Symptoms that persist despite moisturisers and lubricants
- “Thrush” symptoms that repeatedly recur or don’t fully respond
- New urinary symptoms, recurrent UTIs or pain with urination
- Strong fishy odour or grey watery discharge (possible BV)
- Bleeding after sex, pelvic pain, fever, or new vulval skin changes

Available as cream, tablet/pessary or vaginal ring, local oestrogen:
It has minimal systemic absorption and does not require progestogen at licensed low doses.

Bottom Line
Your vaginal and urinary health in midlife isn’t something you need to tolerate in silence. The symptoms of GSM and vaginal dysbiosis are common, biological and entirely treatable. Understanding the role of oestrogen, recognising changes early, and using effective treatments including moisturisers, lubricants, local oestrogen or additional therapies. All can work together to restore comfort, sexual wellbeing and confidence.
Above all:
You do not need to “put up with it.” Help is available, effective, and safe.
