If sex has become painful, if you feel dry, sore or itchy most days, or if you seem to be getting urinary infections you never used to get, there is a good chance the tissue of the vulva, vagina and lower urinary tract has thinned because of a fall in oestrogen. The older name for this is vaginal atrophy. The term used in clinics now is genitourinary syndrome of menopause, or GSM, because the bladder and urethra are involved just as often as the vagina. It is common, it is treatable, and it is one of the things women most often leave unsaid at an appointment, usually because they assume it is simply part of getting older and nothing can be done about it.

This article explains what is actually happening to the tissue, which symptoms belong to GSM and which point somewhere else, why it behaves so differently from hot flushes, and what the treatment options are: from moisturisers and lubricants you can buy yourself, through low-dose local oestrogen, to the other prescribed options, including non-hormonal ones, that are considered for women who cannot or prefer not to use oestrogen. It also sets out what tends to make things worse, and the symptoms that should bring you in promptly rather than waiting to see whether they settle.

What Vaginal Atrophy (GSM) Actually Is

Vaginal atrophy means the tissue of the vagina, vulva and lower urinary tract has become thinner, drier and less elastic because the oestrogen that used to maintain it is no longer there. It is not an infection, it is not damage you have caused, and it is not something you have to accept. It is a predictable tissue response to a hormonal change.

The lining of the vagina, the vestibule, the urethra and the base of the bladder are unusually rich in oestrogen receptors. While oestrogen levels are normal, that lining is several cell layers thick, well supplied with blood, and full of glycogen. Lactobacilli feed on the glycogen and produce lactic acid, which keeps the vaginal pH acidic, usually somewhere around 3.8 to 4.5. That acidity is the vagina's main defence against unwanted bacteria. When oestrogen falls, the lining thins, glycogen drops, lactobacilli decline and the pH rises, often above 5. The protective chemistry of the vagina changes along with its structure.

At the same time the deeper tissue changes. Collagen becomes less organised, elastin is lost, and blood flow to the walls is reduced, so the vagina becomes shorter, narrower and less able to stretch. The normal ridges of the vaginal wall flatten out. Lubrication in response to arousal becomes slower and less generous, because lubrication depends on that blood flow. On the outside, the labia minora may flatten or partly fuse, the entrance can feel tighter, and the opening of the urethra can become more prominent and more easily irritated. The surface is thin enough that ordinary friction can cause small splits and a little bleeding.

Why the name changed

Two older terms are still in circulation. "Atrophic vaginitis" suggests inflammation or infection, which is misleading, and "vaginal atrophy" is both a frightening word and an incomplete one, because it leaves out the bladder and urethral symptoms that bring many women to the clinic in the first place. Genitourinary syndrome of menopause was agreed as a replacement precisely because it describes the whole picture: genital symptoms, sexual symptoms and urinary symptoms arising from the same cause.

It is also extremely common. Most women develop some degree of tissue change after menopause, and roughly half of postmenopausal women report symptoms that genuinely bother them. Far fewer than that ever raise it with a doctor, which is the main reason it goes untreated for years.

The Symptoms: What GSM Actually Feels Like

GSM produces a cluster of genital, sexual and urinary symptoms that are usually persistent and gradual in onset rather than sudden. Most women have several of them at once, and many do not realise the urinary symptoms belong to the same problem as the dryness.

• Dryness, with a tight or raw feeling that is there most of the time, not only during sex
• Burning or stinging, sometimes worse when urine touches the vulva
• Itching, often felt at the entrance rather than deep inside
• Soreness when sitting for long periods, cycling, or wearing fitted clothing
• A thin, watery or pale yellowish discharge, or sometimes almost no discharge at all
• Pain at the entrance during penetration, and a day or two of soreness afterwards
• Light spotting or pink staining after sex, from small splits in a fragile surface – but any bleeding after sex, or at any other time after menopause, must still be assessed, because atrophy is a common cause of such bleeding and never an assumed one (see the list of symptoms needing prompt assessment further down)
• Needing to pass urine more often and more urgently, including waking at night
• Stinging when passing urine, sometimes with no infection present on testing
• Repeated urinary tract infections after years of having none

The sexual symptoms deserve particular attention, because they are the ones women most often describe as the reason they finally made an appointment. The pain of GSM is usually felt at the entrance rather than deep inside, is worst at the beginning of penetration, and improves with lubricant but is not abolished by it. Arousal may feel normal in the mind but the physical response lags behind, so there is simply less natural lubrication to work with. None of this reflects how you feel about your partner.

A great deal of this is misread as thrush. Thrush is typically intensely itchy with a thick white discharge, and after menopause it is actually uncommon unless there is diabetes, recent antibiotics or another reason for it. If you have treated yourself for thrush two or three times without lasting improvement, the diagnosis is probably not thrush. Understanding how to tell a yeast infection from bacterial vaginosis and a urinary infection is genuinely useful here, as is knowing what different types of vaginal discharge indicate, because the thin watery discharge of GSM looks nothing like either of those conditions.

There is also a knock-on effect that matters clinically. When penetration has hurt several times, the pelvic floor muscles learn to tighten in anticipation. That protective tightening then adds a second, muscular layer of pain on top of the tissue problem, and it does not resolve simply by treating the hormone deficiency. If that has happened, the muscular component usually needs addressing in its own right, in much the same way as treatment for vaginismus works on the muscle response alongside anything else that is going on.

Why It Does Not Improve on Its Own, Unlike Hot Flushes

Hot flushes usually fade over a number of years, but GSM does not, because the two have different mechanisms. This single point changes how women think about treatment, so it is worth being clear about.

Hot flushes and night sweats come from instability in the brain's temperature control centre as it adjusts to a new hormonal setting. That centre eventually recalibrates. Most women find vasomotor symptoms peak and then gradually subside, which is why "wait it out" is reasonable advice for some women with flushes.

GSM is not an adjustment phenomenon. It is a structural change in tissue that is actively maintained by a hormone level that is now permanently low. Nothing is recalibrating. For that reason the pattern is the opposite of hot flushes: symptoms tend to begin quietly a year or two around the final period and become more noticeable five, ten or fifteen years later. Women are sometimes told their symptoms cannot be menopausal because menopause was a decade ago. In the case of GSM, a decade later is exactly when it is at its most troublesome.

The practical consequence is that treatment for GSM is ongoing maintenance rather than a course of something. If local treatment is started and then stopped, the tissue drifts back towards its untreated state over a period of weeks to months, and the symptoms return. That is not a sign the treatment failed or stopped working. A closer comparison is the way someone with dry, eczema-prone skin uses an emollient indefinitely, rather than the way someone takes a week of antibiotics for a chest infection and then stops.

Knowing this early saves a lot of frustration. Women who expect a two-week cure often abandon treatment just before it would have made a difference, since the tissue needs several weeks at minimum to rebuild, and sometimes two to three months for the fuller effect.

Who It Affects: Menopause Is the Commonest Cause, Not the Only One

Anything that lowers oestrogen can cause GSM, which is why it is not exclusively a condition of women over fifty. Younger women with the same symptoms are frequently told they are too young for this, and that is incorrect.

• Natural menopause and the perimenopausal years leading up to it
• Surgical menopause after removal of both ovaries, where the drop is abrupt rather than gradual
• Premature ovarian insufficiency, where periods stop before the age of forty
• Breastfeeding, when oestrogen is suppressed by prolactin
• Treatment with GnRH agonists for endometriosis, fibroids or infertility protocols
• Aromatase inhibitors, which reduce oestrogen to very low levels
• Chemotherapy that causes ovarian failure, and radiotherapy to the pelvis
• Smoking, which has an anti-oestrogenic effect and brings menopause forward

Tamoxifen belongs in a separate category, because it does not work by lowering oestrogen. It is a selective oestrogen receptor modulator, so it occupies oestrogen receptors and acts differently in different tissues; in premenopausal women circulating estradiol often rises rather than falls. Dryness and painful sex on tamoxifen are nonetheless real and commonly reported, and they arise from its action on the receptors in the tissue itself rather than from oestrogen depletion. Some women on tamoxifen notice the opposite problem, an increase in watery discharge. Either way the symptoms are worth raising, because the management is not identical to the management of oestrogen-deficient tissue.

Breastfeeding is worth naming separately because it catches so many women by surprise. Oestrogen is low for as long as lactation is well established, so dryness and painful sex are common in the months after birth, particularly alongside perineal healing. This form is temporary and resolves as periods return and feeding reduces, but it does not have to be endured in the meantime: lubricants and moisturisers are entirely appropriate, and in persistent cases a doctor may consider a short course of local oestrogen, which is compatible with breastfeeding.

Cancer treatment produces the most severe form of GSM. Aromatase inhibitors reduce oestrogen to very low levels indeed, and pelvic radiotherapy adds scarring and loss of elasticity on top of hormonal dryness. Women in this group often need a combination of approaches, and they need them discussed openly rather than treated as a side issue, since the symptoms can be the main reason a woman considers stopping an important medication.

GSM also frequently sits alongside the other changes of this stage of life, and it is sensible to look at the whole picture rather than one symptom in isolation. If hot flushes, sleep disruption and mood changes are part of your experience too, it is worth reading about menopause symptoms and the treatment options available, because the decision about systemic treatment and the decision about local treatment are separate decisions that can be made in either order.

One misunderstanding to clear up: not having sex does not cause GSM. The hormone change causes it. However, regular sexual activity or the use of a vaginal trainer does help maintain the calibre and flexibility of the vagina, so a long gap without any penetration can make the entrance feel tighter and more painful when it is attempted again.

Urinary Urgency and Recurrent UTI: The Bladder Side of GSM

The urethra and bladder base develop from the same embryological tissue as the vagina and carry the same oestrogen receptors, so they thin at the same time and for the same reason. This is why bladder symptoms belong in an article about vaginal atrophy.

Two separate things happen. First, the thinned urethral and bladder lining becomes more sensitive, which produces urgency, frequency, night-time waking and a stinging sensation when passing urine even when a urine culture is completely clear. Women are often told repeatedly that there is no infection and given no explanation. The explanation is usually the tissue itself.

Second, the loss of lactobacilli and the rise in vaginal pH removes the chemical barrier that normally keeps bowel bacteria from colonising the area around the urethra. Those bacteria then have a much easier route into the bladder, so genuine, culture-positive urinary infections become more frequent. This is a real and well-recognised reason for recurrent UTI beginning after menopause in a woman who never had them before.

The important clinical point follows from that: treating each infection with antibiotics alone deals with the episode but leaves the reason for the episodes untouched. Restoring the vaginal environment addresses the underlying susceptibility, which is why low-dose vaginal oestrogen is now a standard part of the prevention plan for recurrent urinary infection in postmenopausal women, and not only for women who complain of dryness. If you are having repeated courses of antibiotics, it is reasonable to ask specifically whether this applies to you.

Two practical cautions. Get at least one proper urine culture rather than treating every episode on symptoms alone, because dysuria from thin tissue is indistinguishable from dysuria from infection without a test, and repeated unnecessary antibiotics carry their own problems. And consider whether something mechanical is also involved: incomplete bladder emptying from a prolapse contributes to both urgency and recurrent infection, so if you have a feeling of something bulging or dragging it is worth reading about the symptoms and stages of pelvic organ prolapse, as the two conditions commonly coexist and are often treated together.

Moisturisers vs Lubricants: The Difference and How to Use Each

Lubricants are used at the moment of sex to reduce friction; moisturisers are used regularly, every few days, to hold water in the tissue whether or not you are sexually active. They do different jobs, they are not interchangeable, and many women need both. This is the most common confusion in the whole subject.

Lubricants: for the moment

A lubricant is applied before and during sex and its only job is to reduce friction. Use considerably more than you think you need, apply it to both partners rather than just the entrance, and reapply rather than pushing through discomfort. Water-based lubricants are the usual starting point, are safe with condoms and silicone toys, but dry out and need topping up. Silicone-based lubricants last much longer and suit women with marked dryness, though they should not be used with silicone toys. Oil-based products and plain oils last well but degrade latex condoms, so they are unsuitable if condoms are being used for contraception or infection prevention.

Moisturisers: for the tissue

A vaginal moisturiser is used on a schedule, typically two or three times a week at bedtime, and works by drawing and holding water in the surface tissue. Products based on hyaluronic acid or polycarbophil are the usual choices, and come as gels with an applicator or as small pessaries. They contain no hormones, which makes them a sensible first step for mild symptoms and a mainstay for women who cannot use hormonal treatment at all. Give any moisturiser a fair trial of at least four to six weeks of consistent use before judging it.

Product choice matters more than price. Avoid anything with a warming, tingling or flavoured effect, anything containing spermicide if you are not using it for contraception, and heavily glycerin-based products, which can irritate thin tissue and may encourage thrush in susceptible women. Where the information is available, a product with a pH close to that of the vagina and a low osmolality is gentler on an already fragile surface.

What neither can do is rebuild the tissue. Moisturisers and lubricants manage the surface dryness and the friction very usefully, and for mild symptoms that may be all that is needed. They do not restore epithelial thickness, they do not bring back the lactobacilli, and they do not change the vaginal pH, so they will not resolve the urinary susceptibility. If symptoms persist on consistent non-hormonal treatment, that is the point to discuss something that acts on the tissue itself.

Local Oestrogen: How It Works and What Is Known About Safety

Local oestrogen is a very low dose of oestrogen applied directly into the vagina, which rebuilds the lining, restores glycogen, allows lactobacilli to return and brings the pH back down. It treats the cause rather than the sensation, which is why it also helps the urinary symptoms that moisturisers do not touch.

It comes in several forms, described here by class rather than brand: creams applied with a calibrated applicator, small tablets or pessaries inserted with a disposable applicator, and a soft flexible ring that sits in the vagina and releases a steady low dose over about three months. The hormones used are generally estradiol or estriol, with promestriene available in some countries. The choice between them is largely practical. Creams allow a little to be applied externally to a sore vestibule as well; pessaries are tidier with less discharge; a ring suits women who dislike applicators or find a regular routine hard to maintain. Discuss which suits you, because adherence matters more than the specific preparation.

Most regimens begin with a loading phase of daily or near-daily use for roughly two weeks, then drop to a maintenance dose two or three times a week. Your own doctor will set the regimen and the dose for your situation. Change is gradual: dryness often eases within two to three weeks, with the fuller effect developing over two to three months. Urinary symptoms usually take longer to settle than vaginal dryness.

What is known about safety

The dose used vaginally is a small fraction of the dose in systemic hormone therapy, and with standard low-dose preparations measured blood oestrogen levels remain within the normal postmenopausal range. Because of that, current guidance does not call for a progestogen to be added for endometrial protection in a woman who still has a uterus, which is a genuine difference from systemic oestrogen. There is also no arbitrary time limit: it is continued for as long as the symptoms require, which for most women means indefinitely. Any vaginal bleeding that occurs while you are using it must be assessed properly rather than assumed to be the treatment.

Two further points come up regularly. Local and systemic treatment are not alternatives but can be combined; systemic hormone therapy taken for hot flushes does not always clear vaginal symptoms, and local treatment can be added alongside it. And after breast cancer, local oestrogen is not an absolute prohibition, but it is a decision to be made jointly with the oncology team, particularly for women taking an aromatase inhibitor. In that group non-hormonal measures are generally tried thoroughly first, and if they are inadequate the conversation is an individual one.

Practical niggles are worth anticipating. Creams can leak and are best used at night; some bases cause a little stinging in the first week; and if the entrance has become narrow, an applicator may be uncomfortable at first, in which case applying the cream with a fingertip for the first fortnight is a reasonable way to start.

Other Prescribed Options, Including Non-Hormonal Ones

If oestrogen is unsuitable, unwanted, or insufficient on its own, there are prescribed alternatives that work through different routes. These are decisions for a consultation rather than self-selection, but knowing the landscape helps you ask the right questions.

One point about labelling before the list, because it is easily misread. Only some of these options are genuinely hormone-free. Vaginal DHEA, or prasterone, supplies a precursor that the cells of the tissue convert into oestrogen and androgen, so it acts through hormone made locally. Ospemifene acts directly on the oestrogen receptor. Neither is therefore a hormone-free alternative for a woman who has been advised to avoid oestrogen altogether, for example while taking an aromatase inhibitor, and in that situation the choice belongs with the doctor or oncologist who gave that advice. The local anaesthetic, the physiotherapy and the trainers below involve no hormone at all.

• Vaginal DHEA (prasterone) – a daily pessary containing a hormone precursor that local cells convert into small amounts of oestrogen and androgen within the tissue itself. It suits women who would rather not apply oestrogen directly, and because it has an androgenic component it is sometimes preferred where vestibular discomfort is prominent. Its use after breast cancer has not been established and is decided case by case.
• Ospemifene – a daily tablet from the SERM class, which acts like oestrogen on vaginal tissue while behaving differently elsewhere in the body. It is used mainly for moderate to severe pain with sex. It is taken orally rather than vaginally, which some women much prefer. It should not be combined with tamoxifen, it can provoke hot flushes, and a history of blood clots is a reason for caution.
• Topical local anaesthetic – a lidocaine gel or ointment applied to the vestibule shortly before sex can make penetration tolerable while slower treatments take effect. It is a bridge, not a solution, and a partner should be aware of transfer.
• Pelvic floor physiotherapy – indicated where protective muscle tightening has developed on top of the tissue problem, and also where urgency or leakage is part of the picture. This is frequently the missing piece when oestrogen alone has not resolved painful sex.
• Vaginal trainers or dilators – a graded set used at home to restore comfortable calibre, particularly after a long gap without penetration, after pelvic radiotherapy, or where the introitus has narrowed.

Two things are often asked about and both need a cautious answer. Testosterone, whether applied locally or taken systemically, is not an established treatment for GSM; it has a recognised role in a different indication and should not be assumed to help here. And energy-based devices, meaning fractional laser and radiofrequency treatments marketed for vaginal rejuvenation, are not currently recommended as routine care for GSM by the major professional bodies, because a benefit over placebo treatment has not been demonstrated in good studies. If you are offered one, ask what evidence it rests on and what the alternative would be.

Finally, the sequence usually matters more than the specific product. Non-hormonal measures used properly and consistently for six weeks; then local oestrogen or vaginal DHEA if symptoms persist; then a review at around three months to decide whether the dose, the preparation or the whole approach needs changing; and attention to the muscular and mechanical components throughout rather than at the end.

What Does Not Help, and What Often Makes It Worse

Thin, oestrogen-deficient tissue has very little tolerance for chemical irritation, so a surprising amount of ordinary hygiene activity makes GSM symptoms worse rather than better. Stopping these is free, and for some women it removes a substantial part of the discomfort before any treatment is started.

• Perfumed soaps, shower gels, bubble baths and bath additives used on the vulva
• Intimate washes, feminine deodorants and vaginal douching of any kind
• Wet wipes, including those sold as intimate wipes, because of fragrance and preservatives
• Daily panty liners and heavily fragranced sanitary products
• Tea tree oil, essential oils, antiseptic additives and home remedies such as yoghurt or garlic
• Repeated courses of antifungal treatment when previous courses have not helped
• Repeated antibiotics for urinary symptoms without at least one confirmed urine culture
• Washing more than once a day, or washing inside the vagina
• Tight synthetic underwear and prolonged wear of damp gym clothing

Douching deserves a line of its own. The vagina does not need cleaning from the inside, and douching removes what remains of the protective bacteria while raising the pH further, which is the exact opposite of what GSM tissue needs. The same applies to hygiene products that promise to restore freshness or balance.

Simplifying is the goal. Wash the vulva with plain water or a bland unscented emollient used as a soap substitute, once a day, with your hand rather than a flannel. Pat dry rather than rubbing. Wear cotton underwear and nothing at night if that is comfortable. If hair removal is irritating the skin, change the method rather than persisting with it.

The other thing that genuinely does not help is waiting. Because GSM is progressive, delay allows the tissue to thin further, the introitus to narrow, the pelvic floor to learn its protective pattern, and the urinary problems to establish. It is all treatable at any stage, but it is simpler to treat earlier than later, and there is nothing to be gained from giving it another year.

When to See a Doctor, and What the Examination Involves

Make an appointment if symptoms have persisted for a few weeks, if they interfere with sex, sleep, exercise or daily comfort, or if a sensible non-hormonal routine has not helped after about four to six weeks. You do not need to have tried everything first, and you do not need to apologise for the subject.

Symptoms that should be assessed promptly

• Any vaginal bleeding after menopause, including light spotting and bleeding after sex
• A new lump, ulcer, or a sore that has not healed within a few weeks
• White, thickened or shiny patches of vulval skin, or a change in the shape of the vulva with fusion or loss of definition, which can indicate lichen sclerosus and needs its own treatment
• Pain that is rapidly worsening, or pain severe enough to prevent sitting or walking
• Fever, shivering, back or flank pain, or vomiting alongside urinary symptoms
• Visible blood in the urine, or inability to pass urine
• A heavy, foul-smelling or discoloured discharge
• Vulval itching that persists despite treatment, particularly if confined to one area

The appointment itself begins with a conversation rather than an examination. Expect questions about when the symptoms started and how they have changed, whether pain is at the entrance or deeper, what you have already tried and for how long, what you wash with, your bladder pattern including night-time waking, all current medication including aromatase inhibitors and tamoxifen, your obstetric history, and when your last period and last cervical screening were. Much of the diagnosis is made here.

What the examination involves

Examination is done with your consent, with an explanation first, and you can ask to stop at any point. It starts with simple inspection of the vulva, which on its own often shows the characteristic pallor, loss of tissue bulk, small splits and narrowing of the entrance; in many cases nothing more is needed to make the diagnosis. If an internal examination is appropriate, the smallest comfortable speculum is used with plenty of lubricant, and a narrowed entrance is a reason to use a paediatric or narrow instrument rather than to persist with a standard one. Vaginal pH may be checked, and swabs taken if infection is a realistic possibility. For urinary symptoms a urine sample goes for culture. A persistent or suspicious vulval lesion is biopsied under local anaesthetic rather than watched. Postmenopausal bleeding is investigated with pelvic ultrasound and assessment of the lining of the womb, regardless of how obvious the atrophy looks, because atrophy is a common cause of such bleeding but never the assumed one.

One practical note that helps many women: cervical screening is often painful when GSM is present, and the sample can be harder to obtain from thin tissue. If a smear has been difficult or had to be abandoned, a short period of local oestrogen beforehand frequently makes the next one manageable. If you are weighing up whether your symptoms warrant an appointment at all, they almost certainly do, and these symptoms can be assessed in a women's health consultation, including the parts you would rather not say out loud.
