Understanding GSM: How to Treat Vaginal Dryness in Perimenopause

You have probably heard of vaginal dryness as a menopause symptom. What you may not have heard is that dryness is often just one part of a larger condition called genitourinary syndrome of menopause, or GSM. It also affects the vulva, the bladder, and the urethra, and it can cause things like recurring UTIs and urinary leakage that most women would never connect to their hormones.

Fireese Berg wrote a longer, fully sourced piece going through all of it in detail. But if you want the short version first, here it is.

GSM stands for genitourinary syndrome of menopause. It is the medical term for a collection of changes that happen to the vagina, vulva, clitoris, bladder, and urethra when estrogen drops. Estrogen keeps those tissues thick, moist, and elastic. Without it, they thin out, dry up, and become more prone to irritation, infection, and pain.

It is more common than most people realize. Vaginal dryness alone affects roughly three in four perimenopausal and menopausal women. GSM as a whole affects somewhere between 27 and 84 percent of postmenopausal women, depending on the study. It can also start while you are still cycling. And about 70 percent of women who have it never bring it up with their doctor.

The symptoms of GSM can look like several separate problems, which is part of why it goes unrecognized. The list includes vaginal dryness, burning and irritation, pain during sex, recurring urinary tract infections, pain when you urinate, urinary leakage, reduced discharge, and thinning of the vulvar and vaginal tissue.

In more significant cases, atrophy can occur, meaning the tissue shrinks, thins, loses sensation, and loses function. This can affect the vulva, the vagina, and the clitoris. It is not just discomfort. It is a structural change that affects both everyday life and sexual function.

Recurring UTIs, painful sex, urinary leakage, and burning that won’t resolve can all be part of the same condition. They are not separate bad luck. They are GSM.

There is no straightforward test for GSM. Estrogen levels fluctuate too much during perimenopause to give a clear reading. Diagnosis usually depends on a description of your symptoms, sometimes a pelvic exam, and sometimes a vaginal pH test.

The problem with that is obvious: it puts the entire burden on you to bring it up, name it, and describe it accurately, to a doctor who may never think to ask. If your symptoms fit the picture above and your doctor has not mentioned GSM, it is completely reasonable to name it yourself and ask whether it applies to you.

Lubricants help with dryness and pain during sex. Water-based is generally preferred. The thing most people don’t know: not all lubricants help. Some are formulated in a way that draws moisture out of your tissue rather than adding it, which makes dryness and irritation worse. To avoid those, look for products with an osmolality under 350 mOsm/kg and a pH around 4.5. Many popular brands don’t meet that standard, but some do, and the information is sometimes on the packaging or the company’s website.

Vaginal moisturizers are different from lubricants. They are used regularly, every one to three days, and they work by maintaining moisture in the tissue over time rather than just at the moment of sex. Ingredients like hyaluronic acid and polycarbophil have shown real results. One trial found hyaluronic acid worked as well as local estrogen for vulvovaginal symptoms.

Local estrogen comes as a cream, suppository, or ring inserted into the vagina. It treats the problem at the source by restoring estrogen to the tissue that needs it. At low doses, it does not significantly raise estrogen levels in the rest of your body, which makes it a different category than hormone therapy that works throughout the body.

Hormone therapy may be considered if GSM is happening alongside other significant perimenopausal symptoms like hot flashes, sleep disruption, or mood changes. It comes in several forms including pills, patches, and gels, and works throughout the body rather than just locally. Whether it is right for you depends on your full picture and health history.

Ospemifene is a pill that acts like estrogen in vaginal tissue but not in breast tissue, which makes it a lower-risk option for women who cannot use estrogen. Worth asking about if other options are off the table.

Local estrogen works directly in the tissue that needs it. At low doses it stays local, which is a meaningful difference from hormone therapy that works throughout the body. Both are legitimate options.

GSM is not just a dry vagina. It is a recognized medical condition with a real physiological cause and multiple effective treatments. It affects a huge number of women, starts earlier than most people think, and goes undertreated because most of us never know to name it.

You are not obligated to accept discomfort as a normal part of getting older. If the symptoms in this post sound familiar, you have every right to bring them to your doctor by name and ask what your options are.
