When having intercourse, it stings and hurts, urination is frequent, and cystitis keeps recurring. Many people experiencing these changes simply attribute them to age and endure them for a year or two. However, searching online reveals conflicting information, with terms like "vaginitis" and "cystitis," and articles suggesting only lubricants are needed mixed with those recommending moisturization, making it even more confusing. In the clinic, many individuals in their 40s and 50s come with similar concerns, but understanding the true nature of these symptoms can reveal a path forward.
It's not just dryness, but a syndrome
If you isolate the symptom of vaginal dryness, it might seem minor. However, these perimenopausal and postmenopausal changes affect not only the vagina but also the vulva, urethra, and bladder, forming a cluster of symptoms known as genitourinary syndrome of menopause (GSM). The symptoms are broadly divided into three categories:
- Vaginal symptoms: Not usually felt during daily life, but during intercourse, it feels dry, stings, and hurts; slight bleeding may occur, and the nature of discharge changes.
- Vulvar symptoms: Even friction from underwear can cause irritation, and the vulva may feel thinner than before.
- Urethral symptoms: This is a key aspect. Frequent urination, difficulty holding urine, stinging during urination after intimacy, and recurrent cystitis that wasn't present before.
If you experience cystitis more than twice a year without a special reason, it's advisable to consider this syndrome. Most importantly, this syndrome is not one that improves on its own over time. It does not get better by enduring it; symptoms tend to persist and worsen, so enduring is not a good option.
Why does it occur?
The biggest cause is changes in estrogen. Estrogen is a hormone that kept the mucous membranes of the vagina, vulva, urethra, and bladder moist from puberty until menopause. However, when the ovaries stop functioning due to menopause, estrogen levels gradually drop to near zero, resulting in a cascade of changes.
First, the once plump mucous membranes thin, becoming sensitive to irritation and friction. Second, collagen and elastic fibers decrease. Third, secretions and natural lubrication are almost non-existent. Fourth, the acidity inside the vagina, which was originally acidic, changes, reducing beneficial bacteria like lactobacilli, leading to more frequent vaginitis and cystitis. Ultimately, dryness and recurrent inflammation become intertwined.
This is not a matter of willpower or management, but a physical change resulting from hormonal shifts, so there's no need to blame yourself or your age.
Treatment approaches in stages
Treatment is approached in stages, depending on the severity of symptoms and individual circumstances. The methods available in Korea are summarized as follows:
| Stage | Method | For whom |
|---|---|---|
| 1st Stage | Moisturizers and lubricants | For mild symptoms or when hormone therapy is a concern |
| 2nd Stage | Topical estrogen | When aiming to restore the mucous membrane itself |
| 3rd Stage | Laser | When previous stages are not suitable or require careful consideration |
The first stage, moisturizers and lubricants, is a non-medication approach. Moisturizers are applied two to three times a day to help retain moisture in the mucous membrane, much like applying lotion to the face, and contain ingredients like hyaluronic acid that attract water. Lubricants are not for daily use but are used as needed during intercourse to reduce friction. A common misconception is to consider them the same; moisturizers are for daily use, while lubricants are for when needed, and they can be used together. Very mild symptoms can improve with consistent use of this stage alone. However, it's important to know that this method does not thicken the thinned mucous membrane but only alleviates symptoms.
If symptoms are severe, we recommend consulting rather than trying to manage with self-care alone. Consult about my stage
Topical estrogen to restore the mucous membrane
The core treatment for thinned mucous membranes is topically applied estrogen. It's not an oral medication but comes in the form of vaginal suppositories or creams, typically used about once a week, with dosage adjusted according to symptoms. While moisturizers generally show a 30-40% improvement, topical estrogen is reported in studies to alleviate symptoms by 60-80%. It doesn't just provide moisture; the mucous membrane can recover to some extent, and acidity is restored, which has been reported to also improve recurrent cystitis.
In the clinic, the most common questions are about safety and concerns about breast cancer. To conclude, topically applied hormones are known to have minimal systemic absorption, and various guidelines indicate they are safe for long-term use. However, individuals with a history of uterine disease or breast cancer should thoroughly discuss with medical staff through a consultation before starting. If an overall check of hormonal changes is needed, you can also refer to Guidance on Menopausal Hormones.
Is laser treatment really effective?
This is a question many people are curious about. CO2 laser is most frequently mentioned in studies, based on the principle of stimulating vaginal mucous membranes to aid collagen formation, thicken the mucous membrane, and restore elasticity. To be frank, there are no studies yet that definitively conclude whether it is good or bad across various papers. While short-term effects may exist, it is difficult to consider it a sufficiently verified primary treatment.
However, it is not without meaning. For those for whom stages 1 and 2 are not suitable, or for whom hormone therapy is absolutely not an option, or for those who are hesitant due to fear, it can be a carefully considered alternative. It can be tried after sufficient consultation with certified equipment and trustworthy medical staff. However, laser is not a panacea that solves everything, so you should honestly discuss your symptoms and needs to jointly determine if laser is appropriate or if another treatment is better.
If you have these signs, please visit the clinic
For those who have self-diagnosed up to this point, here are five signs that absolutely require a medical consultation:
- Pain during intercourse that lasts for more than 6 months
- Moisturizers and lubricants have been used but are ineffective
- Recurrent cystitis more than twice a year
- Periods seem to have stopped, but bleeding continues
- Lumps, ulcers, or color changes in the vulva
Especially for the fourth and fifth points, there may be other conditions that need to be differentiated from genitourinary syndrome, so you must visit the clinic. Even if you are not having intercourse, there is much that can be discussed through an internal examination and consultation, so please do not hesitate to visit.

The one thing I want to emphasize most today is this: these changes are not an inevitable part of aging, and they can certainly improve. If you honestly tell us what bothers you most and how you would like to see improvement, we can help you find a path forward. Don't get confused searching alone; feel free to ask.
