Vaginitis symptom checklist, types, and when to get tested

If the color of your vaginal discharge changes from usual, or its odor becomes bothersome, and vulvar itching persists for several days, it can be difficult to focus on daily life. If these changes recur for more than 2-3 days, it's safer to undergo an examination to confirm vaginitis rather than self-diagnose. Today, we've summarized common explanations from our clinic regarding when an examination is necessary and how treatment approaches differ depending on the type of vaginitis.

When to Consider a Vaginitis Examination

Vaginitis can sometimes progress slowly even before clear symptoms are felt. If any of the following signs apply to you, we recommend getting it checked.

• If the color of your discharge is different from usual or its quantity suddenly increases.
• If you notice a peculiar odor or a change from your usual odor.
• If vulvar itching or stinging persists for more than 3 days.
• If you experience discomfort when urinating or pain after sexual intercourse.

If two or more of these symptoms overlap, we recommend confirming the cause with an examination rather than relying on over-the-counter medications.

In the clinic, we often see that even similar itching can have various causes. It's difficult to determine the type based on symptoms alone, so confirmation is key.

Treatment Approaches Differ Depending on the Type of Vaginitis

Even if the symptom is the same itching, the approach changes if the cause is different. If medication bought at a pharmacy doesn't match the cause, it can actually further disrupt the vaginal balance. Here's a table summarizing two common patterns:

Of course, this table is for reference only. It's not uncommon for both types to appear simultaneously, or for examination results to differ even if they look similar on the surface.

Why You Shouldn't Self-Diagnose Based on Symptoms Alone

Even if symptoms appear similar, actual examination results are often quite different. That's why we go through a confirmation process.

• A vaginal discharge smear test examines the type of bacteria under a microscope.
• A pH test checks the vaginal acidity (normal range is generally between 3.8 and 4.5).
• Bacterial culture tests are helpful for checking antibiotic resistance when recurrence is frequent.
• If necessary, STI screening is performed concurrently.

Most examinations are completed in a short time, and for some items, results can be confirmed on the same day. We operate to accommodate those who visit during lunch breaks or after work.

If your symptoms are confusing or you're unsure which examination you need, feel free to write down your symptoms and inquire in advance.

What to Check if Vaginitis Recurrs

If vaginitis recurs two or three times or more per year even after treatment, it's helpful to examine the internal vaginal environment along with the bacteria itself. Recurring vaginitis is usually linked to several intertwined factors.

• Decrease in beneficial bacteria (Lactobacillus) associated with repeated antibiotic use or excessive douching.
• Hormonal changes due to menstrual cycle, stress, or lack of sleep.
• In the case of Trichomonas, mutual confirmation with a partner may be necessary.
• Lifestyle habits such as wearing tight synthetic underwear or wet underwear for prolonged periods.

My treatment approach doesn't stop at eliminating bacteria; it also involves finding the reasons why recurrence happens. Confirming recurrence patterns and lifestyle habits together can change the approach. If bladder discomfort overlaps, we may also consider cystitis treatment, and if it becomes chronic, we may broadly examine it from the perspective of HPV and chronic vaginitis.

Practical Things to Check When Choosing an OB-GYN Clinic

When choosing a clinic, it's good to directly check the following points rather than relying on general promotional phrases:

• Availability of female doctors (Dr. Eun-Jin Lee, our chief physician, personally provides consultations at Blanc OB-GYN).
• Specialist experience (OB-GYN residency at Samsung Medical Center).
• Whether same-day examinations and results are available for certain items.
• Whether they go beyond simple prescriptions to investigate the causes of recurrence.

If you've been postponing your check-up, you might consider combining a well-woman checkup or a cervical cytology (Pap smear) with your vaginitis examination.

Frequently Asked Questions

Q1. Does vaginitis sometimes get better on its own? Mild cases may temporarily improve. However, if the cause remains, it can reappear, so if symptoms persist for more than 3 days, we recommend getting it checked.

Q2. Is there a medical difference in treatment by a female doctor? The treatment content itself is the same. However, some patients say that it helps them explain symptoms more comfortably, which can lead to more accurate information exchange.

Q3. Is vaginitis contagious? Trichomonas vaginitis can be transmitted through sexual contact, so it's important for partners to get checked together. Bacterial vaginosis and candidal vaginitis are mainly related to individual environmental factors, but when they recur, partner factors are also considered.

Q4. Can I try over-the-counter pharmacy medications first? Using them without confirming the type of infection can further disrupt the bacterial balance. If it's your first time experiencing symptoms or if they are recurring, it's safer to proceed after an examination.

Q5. Are there any precautions during treatment? It's crucial to follow the advised treatment plan completely during the treatment period. Arbitrarily stopping treatment when symptoms improve can increase the likelihood of recurrence.

In Summary

Odor, itching, and changes in discharge are signals that are easy to overlook in a busy daily life. If these symptoms appear for the first time or are recurring, getting your current condition checked can bring peace of mind. We will examine your symptom patterns and recurrence patterns together and guide you on the right path.
