Causes

By Mayo Clinic Staff

Yeast infections, bacterial vaginosis and menopause all can change vaginal discharge. These conditions can make you uncomfortable, but there are treatments that can help.

Sometimes, differences in your discharge can be a symptom of something more serious. Some sexually transmitted infections (STIs) can cause changes to vaginal discharge. STIs can be a danger to your body's health and to others. So knowing if you have an STI is important.

Brownish or blood-tinged discharge can be a sign of cervical cancer. But this is rare.
