Why vaginitis keeps recurring: it may not be a hygiene problem

If you've received treatment but soon experience discharge, itching, and odor again, your frustration is completely understandable. The most common question we hear in the clinic is, "I got treated, so why is it back again?" We see this as a sign that, rather than just a simple treatment issue, we need to consider the possibility that the vaginal internal environment is unstable. Hello, I'm Dr. Eun-jin Lee, Chief Director of Blanc OB-GYN. In this article, I will outline the mechanism of recurrent vaginitis and an approach focused on environmental improvement.

Recurrent vaginitis, is it really a hygiene issue?

Many of our recurrent patients blame themselves, wondering if they've managed their hygiene incorrectly. However, frequently recurring vaginitis is often more deeply related to a compromised internal vaginal environment itself, rather than just hygiene.

A healthy vagina is rich in beneficial lactobacilli, which maintain an acidic environment and suppress the growth of harmful bacteria. Vaginitis begins when this balance is disrupted.

Why does it improve with medication only to worsen again?

During antibiotic treatment, both harmful and beneficial bacteria are reduced. The problem arises when harmful bacteria proliferate again before beneficial bacteria have fully recovered. This leads to an unstable pH balance, creating a pattern of recurrent infections.

If medication provides temporary relief but symptoms soon return, it might be time to look beyond the intensity of treatment and consider the recovery of the vaginal internal environment.

3 common causes frequently observed in those with recurrent issues

The following common underlying factors are observed in individuals who experience frequent recurrences:

• Decreased vaginal mucosal thickness: The mucous membrane thins due to age, stress, or hormonal changes, making it vulnerable to irritation. This tends to become more pronounced from the late 30s.
• Increased mucosal dryness: When the mucous membrane becomes dry, its natural defense mechanisms weaken, making it easier for harmful bacteria to settle.
• Lack of beneficial bacteria: Repeated antibiotic use, weakened immunity, and lifestyle habits can lead to a decrease in beneficial bacteria.

Simple treatment vs. environmental improvement, what's the difference?

Not all cases of vaginitis require the same approach. However, if you experience the following situations, it's advisable to consider a different approach:

• If it recurs two or three times or more per year
• If it temporarily improves with medication but then recurs
• If discharge, itching, and odor chronically recur
• If it doesn't resolve despite visiting multiple clinics

In such cases, simple antibiotic treatment may have limitations, so we also consider approaches that improve the vaginal internal environment itself. The goals are to improve mucosal condition, enhance blood flow, and restore natural defense capabilities.

How does Blanc OB-GYN approach it?

Even with the same symptoms, the causes and underlying factors differ from person to person. Therefore, rather than applying the same treatment to everyone, we prioritize distinguishing whether simple treatment is sufficient or if environmental improvement is needed.

1. Examination to confirm the presence and type of vaginitis
2. Assessment of vaginal mucosal condition and dryness
3. Identification of recurrence patterns and lifestyle habits
4. Determination of whether simple treatment is sufficient or if environmental improvement is needed

If you are curious about the examination items, please refer to the STD & Infection Tests guide. For management related to environmental improvement, you can consult Dr. Femin Inner Care and Vaginal Scaling.

Recurrent hygiene concerns, where should I start checking?

Rather than blaming yourself every time symptoms recur, first understanding why they recur can bring greater peace of mind. If you have similar ongoing concerns, you might find it helpful to look at the Recurring Hygiene Issues page, where we've compiled frequently asked questions.

In conclusion

Vaginitis is a common symptom, but once it becomes recurrent, it cannot be viewed simply. Distinguishing whether simple treatment is sufficient or if environmental improvement is needed is paramount. Since the effectiveness and recovery degree vary individually, if symptoms recur, we recommend calmly investigating the underlying cause.
