Vaginal Discharge Changes: What's Normal and When to See a Doctor

Vaginal discharge is a normal, healthy function — it clears dead cells and bacteria and keeps the vaginal environment balanced. Its amount, thickness and color shift across the menstrual cycle: clear and stretchy around ovulation, thicker and whiter beforehand, and often present in small amounts throughout. None of that alone signals a problem.

What does point toward infection is a specific combination of changes rather than any single one: a strong or fishy odor, a shift to grey, green or yellow color, a curd-like or frothy texture, itching, burning, or pain during sex or urination. The two most common causes — bacterial vaginosis, a disruption of the normal bacterial balance, and a yeast infection, an overgrowth of candida — can look similar to the person experiencing them but need opposite treatments, which is why guessing from a pharmacy shelf is the most common reason symptoms come back within weeks.

A short in-clinic examination and swab identifies which it is in a single visit, rather than a cycle of trying one over-the-counter treatment after another. Discharge accompanied by pelvic pain, fever, or bleeding between periods or after sex is evaluated differently and sooner, since those combinations can point to conditions beyond a straightforward infection.

At The Fit Clinic, 8F EM Tower EMSPHERE, Sukhumvit, Bangkok, a gynecologist examination and swab test usually gives a clear answer the same day. If a change in discharge has lasted more than a few days, keeps returning, or comes with pain or odor that concerns you, reach out via Line @THEFITBKK or book a consultation.
