Yellow vaginal fluid is considered to be caused by infection and it is unlikely to recover on its own. The most common cause of yellow vaginal discharge is vaginitis, such as bacterial vaginitis and mycotic vaginitis, which are very common vaginitis diseases and are treated in different ways because of different causative agents. If it is bacterial vaginitis you can use local suppositories such as Ornidazole under doctor’s guidance, if it is mycotic vaginitis you need to treat with Fluconazole. It may also be caused by acute cervicitis or chronic cervicitis, which usually leads to yellowing of the leucorrhea and may cause contact pain and bleeding. It is best to have a cervical examination and abdominal ultrasound to clarify the cause and then target anti-inflammatory treatment.
