How To Manage Chronic Vaginitis

If vaginitis gets better and then flares up again, and the pattern of being briefly fine only while taking medicine repeats, the cause lies not in a single infection but in the balance of the internal vaginal environment. In the clinic, a considerable number of those who come for chronic and recurrent vaginitis blame themselves for having a "constitution that cannot be treated," but in reality only a state in which the balance of beneficial and harmful bacteria has collapsed is being maintained. In this article, we focus on a story one step ahead of treatment methods—that is, lifestyle management that reduces recurrence—and organize habits to protect vaginal health.

The starting point for understanding chronic vaginitis is the fact that the inside of the vagina is by no means a sterile state. In a healthy vagina, various kinds of lactobacilli are dominantly established, and these bacteria make lactic acid and keep the vagina acidic, with a pH between 3.5 and 4.5. According to materials from the U.S. Centers for Disease Control and Prevention (CDC, 2024), this acidic environment serves as a natural defensive barrier that suppresses the proliferation of harmful bacteria.

Representative beneficial bacteria include Lactobacillus crispatus, gasseri, iners, and jensenii. When these bacteria are firmly established, even if a small amount of harmful bacteria enters from outside, it does not cause symptoms or disappears quickly. The experience of discharge increasing a little and then subsiding on its own is, paradoxically, also a sign that the distribution of beneficial bacteria is healthy.

Recurrent vaginitis is usually caused by common bacteria. Gardnerella vaginalis, which causes bacterial vaginosis, ureaplasma, and Candida albicans are representative. Because these bacteria commonly exist around our bodies, a perspective of restoring balance is more realistic than completely eliminating them.

The reason recurrence is frequent is also statistically supported. The American College of Obstetricians and Gynecologists (ACOG, 2020) and CDC materials explain that bacterial vaginosis can reappear in a considerable proportion within several months even after standard antibiotic treatment. This is, rather than the treatment being wrong, a natural pattern that appears when the fundamental factor that broke the balance remains as is. If you are curious about the cause of recurrence, you may also refer to the Q&A organizing why vaginitis keeps recurring.

Antibiotics are the part most easily misunderstood in chronic vaginitis management. When you take antibiotics while having symptoms, it seems to get better, but there are not a few cases of recurrence again once you finish taking them. In clinical experience, these people complain of the greatest frustration, and behind it is the way antibiotics act.

Antibiotics cannot pick out and eliminate only harmful bacteria. Because the beneficial bacteria that protected the vagina also decrease together, using antibiotics repeatedly can rather lower the recovery power of beneficial bacteria. As a result, the balance breaks more easily, and there is also a reported risk of harmful bacteria gaining resistance to antibiotics.

So in chronic vaginitis, use antibiotics minimally, but how to revive the broken balance after stopping is more important. This does not mean denying antibiotic treatment itself, but that a perspective of designing the recovery stage after treatment is needed. If you are curious about the bacteria of bacterial vaginosis itself, please refer to the article explaining Gardnerella bacterial vaginosis.

Regaining balance starts not from a grand prescription but from daily habits. The key is to create an environment good for beneficial bacteria to live in.

• Water intake: 2 liters or more of water a day helps mucosal health and overall condition.
• Taking lactobacilli: Steadily consume lactobacillus strains beneficial to the vagina.
• Gut health: For lactobacilli to reach the vagina well, the gut environment must be healthy. Dietary fiber and regular meals are the foundation.
• Sufficient sleep and stress management: When immunity drops, the balance also breaks easily.

However, the evidence for lactobacilli differs by strain. The CDC (2021) STI treatment guideline specifies that the evidence for the effect of lactobacilli in candida vaginitis is still limited, so it is more accurate to understand supplements not as an all-purpose solution but as one tool that helps restore balance. During periods when immunity has greatly dropped, the method of getting help from an IV for immune reinforcement is also consulted about together in the clinic.

It is also good to know that the distribution of beneficial bacteria in the vagina differs greatly from person to person. This topic is unpacked in more detail in the article dealing with how the distribution of vaginal lactobacilli relates to genetics.

As much as adding good habits, reducing habits that break the balance is also important. In the clinic, there are quite a few cases where management started with good intentions rather encourages vaginitis.

The most representative is vaginal douching (cleansing the inside of the vagina). Materials from the U.S. Office on Women's Health explain that douching breaks the normal bacterial balance and acidity and rather raises the risk of bacterial vaginosis. Frequent douching and the use of unverified disinfectants wash away even the beneficial bacteria and worsen the environment. For the vulva, it is enough to lightly wash only the outside with lukewarm water.

Using a condom during intercourse also helps reduce the influx of external bacteria. The habits of well-ventilated cotton underwear, clothes that are not too tight, and not wearing sweat-soaked clothes for a long time also make a small but meaningful difference.

During the climacteric and menopause, the texture of vaginal health management changes a little. This is because, as the vaginal mucosa thins and dries due to hormonal changes, vaginitis can become more frequent even if you maintain the same habits.

The North American Menopause Society (NAMS, 2020) explains that when estrogen decreases after menopause, lactobacilli decrease and vaginal acidity weakens (pH 5.0 or higher), making it more vulnerable to infection. This is called genitourinary syndrome of menopause (GSM), and is regarded not as simple aging but as a state that needs management. Recurrent vaginitis in this period often cannot be solved by lifestyle habits alone, so depending on need, hormone supplementation such as local estrogen is considered together.

If you are curious about the background of vaginitis suddenly becoming frequent after menopause, please refer to the article unpacking post-menopause vaginitis with the latest research, and if a hormonal change is suspected, we recommend getting it checked through care rather than self-judgment.

Even if you steadily keep the habits so far, separately confirming the balance state of your body objectively is necessary. This is because symptoms being quiet does not mean the balance has fully recovered.

A regular check-up is the way to most accurately narrow down the cause of recurrence. Through bacterial tests and confirmation of the mucosal state, you can judge what management now suits you. If you are more curious about everyday preventive habits, we recommend reading the article organizing how to prevent vaginitis and the column explaining why regular check-ups matter together.

If you are exhausted by recurrent vaginitis, it is better to set a management plan in the direction of restoring balance rather than repeating medicine. Please feel free to be consulted about recurrence patterns and lifestyle management.
