Vaginal discharge is usually normal and essential for a healthy female reproductive system. It can vary in color (clear to milky white), odor, and amount. However, abnormal discharge may be a sign of an infection, particularly if in conjunction with vaginal itching or irritation.
Here are some possible causes of abnormal discharge:
- Bacterial vaginosis - fishy smelling discharge
- Yeast infection - thick and white discharge
- Trichomoniasis - frothy discharge with a green or yellow color
- Chlamydia or gonorrhea - cloudy or yellow discharge
