What is the main reason for white discharge?
Most causes of abnormal vaginal discharge — such as yeast infection, bacterial vaginosis or menopause symptoms — are relatively harmless, but they can be uncomfortable. Abnormal vaginal discharge can also be a symptom of certain sexually transmitted infections (STIs).
Vaginal discharge is a clear, white or off-white fluid that comes out of your vagina. Your uterus, cervix, and vagina produce vaginal discharge, which is mainly made up of cells and bacteria. It helps clean and lubricate your vagina, and helps fight off bad bacteria and infections.
