Vaginal discharge, or mucus, is normal. MayoClinic.com describes it as a combination of fluid, cells and bacteria that are continuously shed through the vagina. The purpose is to clean and protect the vagina. Discharge can be different for each woman and can change throughout the month. A significant change in mucus secretions can indicate a health concern
The National Institutes of Health points out that several normal female bodily functions can increase mucus secretions. These include emotional stress, ovulation, pregnancy and sexual excitement.
Vaginitis is a common bacterial infection in women caused by an imbalance of naturally occurring bacteria in the vaginal tissues. The bacteria levels can be upset in a variety of ways: wearing tight pants, using fragranced soaps or douching.
Symptoms of vaginitis differ from one woman to another. FamilyDoctor.org points out that when vaginitis occurs the discharge amount, color and smell can change from what a woman typically experiences. The secretions can significantly increase. The odor is often foul and the color may be white or greenish. Skin tissues may become inflamed and itchy. An oral antibiotic is prescribed to treat this infection.
