Vaginal discharge is composed of the following:

• Secretions or mucus produced by the uterine skin, the endometrium, and the Bartholin’s valve.
• Dead cells from the cervix and vaginal epithelium.
• Fluid that passes through the walls of the blood vessels, which carry blood to the organs of the reproductive system.
• A large number of bacteria that colonize the vagina.
• Secretions produced by the sebaceous and sweat glands of the vulvar vestibule.

In short, vaginal discharge is composed of mucus, water, and cells that are normally found in your body.

Furthermore, vaginal discharge is completely normal and not unpleasant. It is as natural as saliva in the mouth.

When is vaginal discharge indicative of disease?

Normally, discharge is odorless; white or clear; thick and sticky; or runny and stretchy.

However, if the discharge is unusual, it may indicate:

Yeast Infection: In this case, the discharge is lumpy.
Bacterial Vaginosis: This is the discharge that generates the famous fishy odor.
Trichomoniasis: This discharge is yellow or greenish and foamy.
