GSM: dryness, burning, bladder symptoms, and discomfort with sex
Doctors use the term genitourinary syndrome of menopause, or GSM, for low-oestrogen tissue change affecting the vulva, vagina, urine passage, and bladder area. It often becomes most obvious after menopause, but it can start in perimenopause and in some other lower-oestrogen situations too.
GSM can show up as burning, stinging, friction, pain with sex, bladder irritation, urgency, recurrent UTI-type symptoms, or a general sense that the tissues have become more fragile and easily upset. Once that pattern is recognised properly, treatment usually becomes calmer, more precise, and much more effective.
In my practice, the job is often deciding whether this is mainly straightforward low-oestrogen tissue change or whether one other problem is also driving the story. That changes the plan much more than simply adding another cream or another antibiotic.
When I would usually look beyond routine GSM first
These situations usually need earlier review or a different route rather than a simple GSM treatment plan:
- Bleeding after 12 months without a period, or bleeding with sex that is not clearly explained and settling.
- Fever, flank pain, vomiting, or feeling systemically unwell with urinary symptoms.
- A visible vulval sore, ulcer, lump, new skin change, or persistent discharge or smell.
- Blood in the urine, bladder-filling pain, or repeated clearly positive urine cultures that may point away from GSM alone.
- A major change in emptying, retention, or prolapse symptoms that have become more prominent than dryness or irritation.
The point is not to make GSM feel dangerous. It is to make sure bleeding, infection, skin disease, bladder-pain work-up, retention, or a more structural pelvic problem are not being forced into the GSM label.
What GSM is and what it can feel like
GSM is a low-oestrogen tissue change that can feel genital, urinary, sexual, or mixed
It is not only a vaginal dryness diagnosis. The same low-oestrogen shift can change the skin, vaginal walls, urine passage, bladder outlet, and the way the tissues respond to friction, urine, sex, and everyday irritation. That is why one woman may experience GSM mainly as dryness, another as bladder-type symptoms, and another as discomfort with sex.
Why the tissue changes
With lower oestrogen the tissue becomes thinner, drier, and less resilient. The healthy bacteria balance changes too, the vagina becomes less acidic, and the whole area becomes easier to irritate than it used to be.
Dryness, burning, and fragility
The area may feel raw, dry, sore, itchy, or easily irritated after urine contact, exercise, washing, underwear friction, or simply at the end of the day. Some women mainly notice that the tissue seems slower to recover.
Bladder and urine-passage symptoms
Urgency, frequency, burning when you pass urine, soreness around the urine passage, and recurrent UTI-type flares can all belong to GSM because the bladder-adjacent tissues are affected too.
Sex discomfort and friction pain
Entry may feel sore, tight, dry, or as if the tissue tears easily. Some women notice spotting, a dragging feeling, or increasing fear of friction because sex has become associated with pain.
This is why GSM is not simply “vaginal dryness”. It is a wider low-oestrogen tissue syndrome, and it is also why local treatment can help: the aim is to rebuild moisture, elasticity, and resilience rather than just mask irritation for a day or two.
What can overlap
GSM is common, but it is not the only explanation for burning, urgency, or sex pain
This is why the best review usually separates GSM from the conditions that mimic it, and also recognises when more than one route is true at the same time.
These are the routes I usually separate first
Burning, bladder irritation, sex pain, and external soreness can come from tissue change, infection, bladder sensitivity, vulval skin disease, or more than one route at the same time. Once the leading route is clearer, the treatment conversation usually becomes much calmer and much more precise.
Recurrent UTI can overlap or be mistaken for GSM
Some women have true infection. Others have repeated burning that sounds like infection but is largely tissue irritation. Sometimes both are happening together.
Bladder pain syndrome can also look similar
If pain or pressure builds with bladder filling and eases after emptying, especially with repeatedly negative cultures, bladder pain may be leading more than GSM.
Urgency and overactive bladder may need their own route
GSM can aggravate urgency, but if the main story is rushing, short warning time, and planning around the toilet, the bladder route often needs to lead too.
Thrush, lichen sclerosus, vulval irritation, and pain conditions matter too
Entry pain, itching, splitting, discharge, white or pale skin change, soreness that is mainly external, or pain that feels more vulval than vaginal may mean the better route includes thrush treatment, vulval diagnosis, or pelvic floor and pain care rather than GSM treatment alone.
More than one card can be true. The specialist job is often deciding which route is leading rather than assuming all the symptoms must have one explanation.
Diagnosis
GSM is usually diagnosed from the story and examination, not one test result
The answer usually comes from the history, a gentle examination, and deciding whether something else is doing a better job of explaining the story.
Step 1
The symptom pattern and timing come first
I want to know whether the main problem is dryness, burning, pain with sex, recurrent UTI-type flares, urgency, soreness around the urine passage, or a wider mixed story, and how that pattern relates to menopause or another time when oestrogen may be lower than usual.
Step 2
A gentle examination often makes the diagnosis much clearer
Pale, dry, smooth, fragile tissue, tenderness at the vaginal entrance, loss of elasticity, or narrowing often support the diagnosis. I also look carefully for lichen sclerosus, contact or product irritation, thrush or discharge-led irritation, prolapse, and pelvic floor overactivity.
Step 3
Urine tests and vaginal acidity can help when the story is mixed
If urinary symptoms are prominent, urinalysis and culture help separate infection from look-alikes. Checking the vaginal acidity, sometimes called pH, may also support the low-oestrogen picture, but it is not usually the thing that makes the diagnosis on its own.
Step 4
More tests are for selected stories, not routine for everyone
Swabs, urine cultures, biopsy, cystoscopy, bladder scans, or broader work-up usually matter when there is discharge, treatment-resistant irritation, white skin change, blood, persistent pain, poor emptying, prolapse, or a still-confusing story that suggests GSM is not the whole explanation.
The diagnosis is usually made when the symptoms and examination fit low-oestrogen tissue change, and another diagnosis is not doing a better job of explaining what is happening.
What usually helps first
Treatment usually works best when the tissue is supported properly and the plan fits the main symptom pattern
Many women improve with good daily tissue care plus the right local treatment. Others also need the plan widened because pain, bladder symptoms, or infection are still clearly part of the picture.
Start with day-to-day tissue support
Gentle washing, less friction, regular moisturiser, and lubricant when needed are the foundation. If the vulva or entrance is the sorest area, bland external care can matter as much as what goes inside the vagina.
Then match the treatment to the part of the story that is leading
Low-dose vaginal oestrogen usually does the deeper repair work. If bladder symptoms, recurrent UTI-type flares, or sex pain still lead, the plan often needs widening early rather than simply repeating the same cream or tablet.
The main decision here is usually not the brand name. It is whether vaginal oestrogen is the right route, which form best matches where your symptoms are sitting, and whether the story still needs a second treatment lane.
Vaginal oestrogen explained
Choosing the right option for your symptoms
Low-dose vaginal oestrogen is local tissue treatment. All of these options can be effective. The choice is usually about where your symptoms are, which formulation feels easiest to use consistently, and whether the discomfort is mainly internal, external, or both.
Where are your symptoms most noticeable?
External
vulva / entrance
- Burning
- Tearing
- Pain with entry
Cream-based options are often more useful here
Internal
vaginal / bladder
- Dryness
- Irritation
- Bladder symptoms
Tablet or pessary options are often easier here
How I usually guide patients
- External discomfort: creams are usually more effective because they can be applied directly where symptoms are worst.
- Internal symptoms: tablets or pessaries are often easier, cleaner, and simpler to maintain.
- Mixed symptoms: some women do best with a combination of internal support and a small amount of cream externally.
Comparing your options
| Option | Best for | What it feels like | Downsides | Practical tip |
|---|---|---|---|---|
Conjugated oestrogen vaginal cream (e.g. Premarin)
| External soreness, entrance pain, vulval or introital fragility | Local and direct | Messy, can leak | Best used at night; a small amount can also be applied externally |
Estriol vaginal cream (e.g. Synapause)
| External sensitivity, friction pain, entrance discomfort | Local and direct | Mess, consistency needed | Often easiest at night; many women use a small amount exactly where needed |
Estradiol vaginal tablet (e.g. Vagifem)
| Internal dryness, bladder irritation, internal discomfort | Clean and easy | May not fully relieve mainly external symptoms | After the initial loading phase, it settles into a simple twice-weekly routine |
Estriol with lactobacillus vaginal tablet (e.g. Gynoflor)
| Internal vaginal support when dryness or irritation overlaps with microbiome support | Supportive and internal | Less direct for prominent external discomfort | More useful when the aim includes support of the vaginal environment, not only coating the entrance tissue |
How to use each option
Cream options
Conjugated oestrogen or estriol vaginal cream, for example Premarin or Synapause
Typical starting use is once daily at night for 2 to 3 weeks, then 2 to 3 times per week. It is inserted into the vagina with the applicator, and a small amount can also be applied at the entrance if that is where symptoms are worst.
What to know: The cream routes are broadly similar in how they are used. They can be soothing quite quickly, but they are often messier than tablets.
Estradiol vaginal tablet (e.g. Vagifem)
Use one vaginal tablet daily for the first 2 weeks, then one tablet twice weekly. It is inserted high into the vagina using the disposable applicator.
What to know: Usually the cleanest and easiest option to maintain.
Estriol with lactobacillus vaginal tablet (e.g. Gynoflor)
A common starting approach is one vaginal tablet daily for at least 12 days, then a maintenance routine 2 to 3 times per week if needed. The tablet is usually moistened first and then inserted into the vagina with the finger at night.
What to know: The tablet softens into a gel-like texture, so it is not usually very messy, but it is still mainly an internal treatment rather than a direct external coating treatment.
If symptoms are both external and internal
Some women do best with an internal option for the vaginal and bladder symptoms, plus a very small amount of cream externally where the entrance tissue is most sore or fragile.
What to know: Mixed symptoms often need a mixed plan rather than trying to make one formulation do every job.
What most women notice when they start
Creams
- Often feel soothing quite quickly
- Can be messy at first
- Best used at night
- More helpful when symptoms are focused around the entrance or outer tissue
Tablets / pessaries
- Cleaner and easier to use long term
- Improvement can feel more gradual
- Often simpler to maintain
- May be less effective when discomfort is mainly external
Treatment is often individual
There is no single perfect option. The aim is to find a treatment that matches where your symptoms are, feels manageable in everyday life, and gives you enough relief to use it consistently. In some women with both internal and external symptoms, a combination approach works best.
If you have used the loading phase properly and things are still not clearly settling after the first review window, that is usually the point to rethink the diagnosis, the formulation, how it is being applied, and whether another route is still being missed.
Why this is different from systemic HRT
Low-dose vaginal oestrogen is aimed at the tissues of the vulva, vagina, and bladder area itself. It is not being used like full-body hormone therapy for hot flushes, sleep, or bone protection. That is why the benefit-risk conversation is different.
- Local treatment: the dose is aimed at the tissues where the symptoms are, not at creating a strong full-body hormone effect.
- Often long term: GSM is usually a chronic low-oestrogen tissue problem, so many women use local treatment for years rather than as one short course.
- Sometimes still possible when HRT is not: even if systemic HRT is contraindicated, low-dose vaginal oestrogen may still be considered in some women, although certain histories need a more careful shared decision.
Low-dose vaginal oestrogen does not usually mean you need progesterone as well, and it can also be used alongside systemic HRT if flushes are treated but vaginal or bladder symptoms are still leading. That does not mean it is automatic for everyone. Unexplained bleeding, active oncology treatment, or a clearly hormone-sensitive cancer history often means the conversation needs more nuance, not less.
These preparations are not only for women whose periods have fully stopped
Low-dose vaginal oestrogen is often thought of as a strictly postmenopausal treatment, but the same low-oestrogen tissue pattern can start earlier. Some women notice it during perimenopause while periods are still coming, and some younger women develop very similar symptoms in other situations where oestrogen drops.
Perimenopause
Some women develop burning, dryness, discomfort with sex, bladder irritation, or recurrent UTI-type symptoms while periods are still happening but have become less predictable. If the history and examination fit low-oestrogen tissue change, local treatment can still be useful at this stage.
Selected premenopausal lower-oestrogen situations
Before menopause, similar tissue symptoms can happen if oestrogen is low for another reason, such as breastfeeding, treatment that switches the ovaries off temporarily, some cancer treatments, or early ovarian insufficiency. In those situations, local treatment may still help, but the wider context matters more.
What to know: In younger women I am usually a little more careful about the diagnosis first, because infection, skin conditions, pelvic pain, and contraception-related issues can mimic the same symptoms.
Where specialist care helps
The specialist value is often deciding how safely and how far to go, not just adding another cream
This is where a urogynaecology review often adds more than a generic dryness conversation. The plan becomes better when the safety questions, persistent symptoms, and later options are dealt with honestly.
What if you have had breast cancer or a hormonally driven ovarian cancer?
Nonhormonal treatment usually comes first: moisturisers, lubricants, better vulval care, and treating overlap routes such as pelvic floor tension or bladder pain. But low-dose vaginal oestrogen is not automatically impossible just because you have had cancer.
For many women with a history of breast cancer, low-dose vaginal oestrogen can still be discussed if symptoms remain intrusive despite simpler treatment. If you are on an aromatase inhibitor, or if the prior cancer was clearly hormone-sensitive, I usually want that decision shared with the oncology team rather than made in isolation. For ovarian and other gynaecological cancer survivors, the answer depends on the cancer type, whether it was hormone-sensitive, and what treatment you are on now, so this is where an individual plan matters more than a blanket yes-or-no rule.
Persistent bladder, infection, or pain overlap still needs its own route
If burning, urgency, recurrent UTI-type flares, bladder-filling pain, or sex pain keep leading the story, the answer is usually not simply more oestrogen. That is when I widen the plan honestly and treat the overlap properly.
There are other routes when standard local oestrogen is not enough
Selected women may discuss other specialist options such as vaginal dehydroepiandrosterone where available and appropriate, but these are not the routine first answer for most women and local vaginal oestrogen still carries the strongest everyday evidence.
Oral ospemifene exists internationally, but it is not a routine South African option
Ospemifene is an oral option used in some countries, but it is not commercially available in South Africa and is therefore not a practical everyday route here. In some settings it may be imported, but it is not where I usually start the conversation.
Laser is not part of my routine GSM practice
Energy-based vaginal laser is marketed aggressively, but the evidence is still limited and regulators have warned against overstating what these devices can do. I do not offer laser in my practice and I do not think it should be sold as the default next step when better-studied treatment has not yet been properly used.
Most women do not need an elaborate treatment ladder. The specialist value is matching the form, the safety conversation, and the overlap route to the actual symptoms in front of us.
Next step
If the tissues are burning, dry, fragile, or making the bladder feel constantly unsettled, the goal is to treat the low-oestrogen change properly and work out whether anything else is still driving symptoms.
A proper review often clarifies whether the tissues mainly need better local treatment, whether another diagnosis is sitting beside it, or both. Once that is clearer, treatment becomes much more precise.
Frequently asked questions
Common questions about GSM, dryness, burning, and bladder symptoms
What does GSM actually mean?
GSM stands for genitourinary syndrome of menopause. It is the name doctors use for low-oestrogen tissue change affecting the vulva, vagina, urine passage, and bladder area, which can cause dryness, burning, discomfort with sex, and urinary symptoms.
Is GSM just another name for vaginal dryness?
No. Dryness is only one part of it. GSM can also cause stinging, burning, irritation, pain with sex, urinary urgency, burning when you pass urine, soreness around the urine passage, and recurrent UTI-type symptoms.
Can GSM really feel like a UTI?
Yes. GSM can cause burning, urgency, and bladder discomfort that feel very similar to infection. Some women also develop true recurrent UTI on top of GSM, which is why the urine history and cultures matter.
How do you make the diagnosis?
GSM is mainly diagnosed from your symptom pattern and a gentle examination. Menopause, perimenopause, or another situation where oestrogen is lower than usual often helps explain why it has started. Urine tests, checking the vaginal acidity or pH, and other tests are mainly used when another diagnosis also needs to be excluded.
What usually helps first?
Most women start with moisturisers, lubricants, and gentle vulval care. Low-dose local vaginal oestrogen is often the most effective treatment when symptoms are bothersome or persistent. Pelvic-floor physiotherapy may help when pain with sex or muscle tension are also part of the story.
What does vaginal oestrogen actually do?
It treats the low-oestrogen tissue change directly. The aim is to make the tissue less dry, less fragile, less sore, and more resilient again. That is why it can help dryness, burning, discomfort with sex, urinary stinging, and some recurrent UTI-type patterns that are being amplified by menopause tissue change.
Is vaginal oestrogen the same as HRT?
No. Low-dose vaginal oestrogen is local treatment aimed at the tissues of the vagina, vulva, and urine-passage area. Systemic hormone therapy is used more broadly for symptoms such as hot flushes. Because the treatment is local, the risk-benefit conversation is different, many women use it long term, and in some carefully selected cases it may still be considered even when systemic HRT is not appropriate.
Do I need progesterone if I use vaginal oestrogen?
Not usually. Low-dose vaginal oestrogen is local treatment, so women do not usually need added progesterone just for endometrial protection when this is used on its own. That said, unexplained bleeding still needs the right review rather than being ignored.
Can I use vaginal oestrogen if I am already on HRT?
Yes, sometimes. Some women still have vaginal, vulval, bladder, or sex-related symptoms even when systemic HRT has helped their flushes or sleep. In that situation, low-dose vaginal oestrogen can still be added if needed.
Can vaginal oestrogen ever be used if you are perimenopausal or not yet menopausal?
Yes, sometimes. Perimenopausal women can develop the same low-oestrogen tissue symptoms before periods stop completely. Similar symptoms can also happen before menopause in other situations where oestrogen drops, such as breastfeeding, treatment that switches the ovaries off temporarily, some cancer treatments, or early ovarian insufficiency. In younger women I am usually more careful about confirming the diagnosis first, because infection, skin conditions, pelvic pain, and contraception-related issues can look similar.
How long does vaginal oestrogen take to help?
Some women notice improvement within a few weeks, but fuller benefit often takes longer. GSM usually behaves like a chronic low-oestrogen tissue condition, so treatment often needs maintenance rather than one short course.
Which form of vaginal oestrogen usually suits which symptom pattern?
If the outer tissue and vaginal entrance are most sore, a cream is often the better fit because it can coat that area directly. If the symptoms are more internal and you want a neater option, a vaginal tablet or pessary may suit better. The best choice is usually the one that matches where the symptoms sit and what you will realistically use consistently.
What if I have had breast cancer or a hormonally driven ovarian cancer?
That does not automatically mean no treatment is possible, but it does mean the plan should be individualised. Nonhormonal options usually come first, and if symptoms remain severe, low-dose vaginal oestrogen may still be discussed with the oncology team. The conversation is usually stricter if you are on an aromatase inhibitor or if the previous cancer was clearly hormone-sensitive.
When should I review if treatment is not helping enough?
If you have used the treatment consistently through the loading phase and the tissues still are not clearly settling, it is worth reviewing the diagnosis, the product choice, how it is being applied, and whether another problem is also driving symptoms.
Why is sex still painful even if the tissue looks better?
Sometimes the tissue improves but pelvic-floor tension, guarding, fear of pain, or a wider pelvic-pain pattern continue. That is when pelvic-floor physiotherapy and pain-focused care become important alongside tissue treatment.
What about laser or ospemifene?
They are not the routine starting point. Vaginal laser is heavily marketed, but the evidence is still limited and I do not offer it in my practice. Oral ospemifene exists internationally, but it is not commercially available in South Africa and is therefore not a practical everyday route here.
