Most causes of abnormal vaginal discharge — such as yeast infection, bacterial vaginosis or menopause symptoms — are relatively harmless, but they can be very uncomfortable.
Abnormal vaginal discharge can also be a symptom of certain sexually transmitted infections. Since these infections can be passed on to other sexual partners — or can spread to the uterus, ovaries and fallopian tubes — detection and treatment is important.
Very rarely, a brownish or blood-tinged vaginal discharge could be a sign of cervical cancer.
Other causes of vaginal discharge may include:
- Bacterial vaginosis
- Cervical cancer
- Genital warts
- HPV infection
- Pelvic inflammatory disease (PID)
- Rectovaginal fistula
- Sexually transmitted diseases (STDs)
- Vaginal atrophy
- Vaginal cancer
- Vesicovaginal fistula
- Yeast infection (vaginal)
