Vaginal discharge refers to secretions from the vagina. The discharge may be:
- Thick, pasty, or thin
- Clear, cloudy, bloody, white, yellow, or green
- Odorless or have a bad odor
Itching of the skin of the vagina and the surrounding area (vulva) may be present along with vaginal discharge. It can also occur on its own.
Causes
Glands in the cervix and the walls of the vagina normally produce clear mucus. This is very common among women of childbearing age.
- These secretions may turn white or yellow when exposed to the air.
- The amount of mucus produced varies during the menstrual cycle. This happens due to the change in hormone levels in the body.
The following factors can increase the amount of normal vaginal discharge:
- Ovulation (the release of an egg from your ovary in the middle of menstrual cycle)
- Pregnancy
- Sexual excitement
Different types of infections may cause itching or an abnormal discharge in the vagina. Abnormal discharge means abnormal color (brown, green), and odor. It is associated with itching or irritation.
These include:
- Infections spread during sexual contact. These include chlamydia, gonorrhea (GC), and trichomoniasis.
- Vaginal yeast infection, caused by a fungus.
- Normal bacteria that live in the vagina overgrow and cause a gray discharge and fishy odor. This is called bacterial vaginosis (BV). BV is not spread through sexual contact.
Other causes of vaginal discharge and itching may be:
- Menopause and low estrogen levels. This may lead to vaginal dryness and other symptoms (atrophic vaginitis).
- Forgotten tampon or foreign body. This may cause a foul odor.
- Chemicals found in detergents, fabric softeners, feminine sprays, ointments, creams, douches, and contraceptive foams or jellies or creams. This may irritate the vagina or the skin around the vagina.
Less common causes include:
- Cancer of the vulva, cervix, vagina, uterus, or fallopian tubes
- Skin conditions, such as desquamative vaginitis and lichen planus
When to Contact a Medical Professional
