Yellow mucus vaginal discharge can sometimes be a sign of an infection, with bacterial vaginosis or trichomoniasis being potential causes.
Your body makes vaginal discharge all the time to keep the area clean, which is usually clear or white. When the discharge turns yellow and has a mucus-like consistency, it might be because your body is fighting an infection. One common infection that can cause yellow, mucus discharge is trichomoniasis, which is caused by the tiny germ Trichomonas vaginalis. This infection sometimes sticks around and can make the discharge yellow because it changes the normal balance in the vagina. Other conditions, like cervicitis (inflammation of the cervix), can also cause yellow discharge, but trichomoniasis is often noticed for the yellowish, mucus appearance. It is important to watch for any other symptoms, such as itching, burning, or discomfort. If you experience any of these or if the discharge continues, talk with a healthcare provider. They can do tests to find out what is causing the change and help decide the best treatment to keep you healthy.
