What are the potential causes of frothy vaginal discharge?

Frothy discharge means the fluid looks bubbly or frothy. One common cause is trichomoniasis. This is an infection from a tiny germ called Trichomonas vaginalis, which can make the discharge look frothy and sometimes come with itching or irritation. Besides trichomoniasis, other infections that disturb the normal balance of germs in your vagina might occasionally lead to unusual discharge patterns, including frothy discharge. Your body usually has many good germs that keep everything balanced, but when the balance changes because of an infection, the discharge may look different. Doctors can check by doing tests to see which germ is causing the change. While frothy discharge is most often related to trichomoniasis, if you notice any discomfort, itching, burning, or changes in your discharge, you can use Ubie's free symptom checker to help identify possible causes before talking with a healthcare provider.
