Vaginal itching, discharge or burning: causes and when to seek help
Guide to vaginitis, candidiasis, vaginosis, vaginal discharge, diagnosis and signs for an in-person review.
The essentials in less than a minute
- Itching, stinging, odor or change in discharge can have different causes and not all are treated the same way.
- Candidiasis, bacterial vaginosis, trichomoniasis, irritation and hormonal changes can look alike.
- Repeatedly self-treating without confirming the cause can delay the correct diagnosis.
- Pelvic pain, fever, pregnancy, bleeding or risk of STIs require specific assessment.
Why do the symptoms look alike?
Vaginitis describes vaginal inflammation and may be due to changes in flora, fungi, sexually transmitted infections, irritants or hormonal changes. The appearance of the flow guides, but rarely allows the cause to be confirmed on its own.
| Pattern | Possibilities to evaluate |
|---|---|
| Intense itching and whitish discharge | Candidiasis, irritation or other causes. |
| Strong smell and finer flow | Bacterial vaginosis, among others. |
| Recent sexual discharge and risk | Trichomoniasis, chlamydia, gonorrhea or other STI. |
| Dryness and itching in menopause | Genitourinary syndrome of menopause. |
What the professional checks
The onset, odor, color and amount of discharge, itching, painful urination, pelvic pain, bleeding, pregnancy, new hygiene products, recent antibiotics, menopause and sexual exposure matter. Some situations require exploration and sampling.
Common mistakes when treating yourself
Candidiasis and vaginosis may share discomforts, but require different treatments. Using an antifungal when the cause is something else can mask or prolong the problem. Vaginal douches and scented products can also irritate or alter the vaginal environment.
Avoid blind treatment if repeated
If it is the first episode, there is pregnancy, the condition recurs or the usual treatment does not work, it is advisable to confirm the cause before repeating medication.
When in-person care is needed
Seek an in-person evaluation if there is fever, significant pelvic pain, unexpected bleeding, ulcers or blisters, poor general condition, pregnancy, possible foreign body or risk of an STI. An online consultation can guide, but does not replace an examination or sample when necessary.
