Why vaginitis keeps recurring: when simple treatment isn't enough

When vaginitis seems to get better but then starts again shortly after, it's natural to worry if there's something wrong with your body. To get straight to the point, recurrent vaginitis can be a sign that the vaginal internal environment is weakened, rather than just the bacteria itself, so simple antimicrobial treatment often isn't enough.

In the clinic, it's not uncommon for patients to return, reporting that symptoms subsided while taking medication but the same discomfort recurred a few days or weeks later. In such cases, going a step further than just treating the infectious agent, and addressing the vaginal internal environment itself, can be helpful.

Why does vaginitis keep recurring?

The reason for recurrent vaginitis is not simply one type of bacteria or fungus. Even if the inflammation-causing bacteria are treated, if the protective environment within the vagina is weakened, discomfort is likely to recur. Commonly reported contributing factors include:

• Weakened elasticity and thickness of the vaginal mucosa
• Imbalance of beneficial vaginal bacteria
• Persistent vaginal dryness
• Decreased immune balance due to fatigue or stress

In such conditions, even if medication alleviates the inflammation, the problem can recur if the environment is not restored. This is why vaginitis/STI care involves examining environmental factors along with bacterial tests.

What are the signs of a weakened vaginal environment?

When the vaginal internal environment is weakened, the following changes may also appear:

• Feeling that vaginitis frequently recurs
• Changes in the amount or nature of discharge
• Feeling of vaginal dryness
• Persistent discomfort at the vaginal opening or inside

If these signs recur, it's necessary to check if there are accompanying environmental changes such as vaginal dryness and atrophy. This is because even if they seem similar, different causes require different approaches.

What we check in the clinic when it recurs

When vaginitis keeps recurring, OB-GYNs don't just look at one type of bacteria but examine various factors together. Here's a summary of what we check:

Even for the same vaginitis, the treatment approach differs depending on whether it's a simple infection or a recurrence due to a weakened environment. This is why we examine the pattern of recurrence.

If a bacterial test is needed, STD infection tests may be performed concurrently to more accurately identify the causative agent.

Treatment consultation to help restore vaginal environment

Recently, if vaginal mucosal weakening is the background to recurrent discomfort, we sometimes offer consultation for vaginal laser treatment to help restore the mucosa. Vaginal laser is known to gently stimulate vaginal mucosal tissue to induce collagen regeneration and can help restore the vaginal internal environment. The effectiveness and sensation vary individually.

Consultation may be considered in the following cases:

• When vaginitis frequently recurs, causing daily discomfort
• When vaginal dryness symptoms are also present
• When a decrease in mucosal elasticity is felt

Whether treatment is necessary and which method is appropriate depends on the individual's condition and is determined through consultation with medical staff. Methods that address the mucosal environment, such as vaginal tightening laser Evro, are guided based on examination results.

How many sessions of treatment are usually performed?

Vaginal laser treatment is usually guided with the following flow:

The recommended number of sessions may vary depending on the vaginal mucosal condition and the degree of recurrence, and not everyone receives the same schedule. An accurate plan is provided individually after examination.

If vaginitis keeps recurring

If vaginitis recurs, rather than repeating the same medication, it can be helpful to check the vaginal environmental status and mucosal status together and find a method suitable for your body. Often, once the cause is properly identified, the same concerns are less likely to recur.

At Blanc OB-GYN, female doctors identify the cause of recurrent vaginitis and provide consultation tailored to the patient's condition. If the same discomfort keeps returning, we recommend getting it checked without delay.
