Vaginal discharge

Definition

Alternative Names

Considerations

Having some amount of vaginal discharge is normal, especially if you are of childbearing age. Glands in the cervix produce a clear mucus. These secretions may turn white or yellow when exposed to the air. These are all normal variations.

The amount of mucus produced by the cervical glands varies throughout the menstrual cycle. This is normal and depends on the amount of estrogen circulating in your body.

Vaginal discharge that suddenly differs in color, odor, or consistency, or significantly increases or decreases in amount, may indicate an underlying problem like an infection. If abnormal vaginal discharge is due to a sexually transmitted disease (STD), your sexual partner(s) will likely require treatment as well.

Causes

The following situations can increase the amount of normal vaginal discharge:

• Sexual excitement
• Emotional stress
• Ovulation (when you produce and release an egg from your ovary in the middle of your menstrual cycle)

These conditions can lead to abnormal vaginal discharge:

• Vaginal yeast infection -- the discharge is generally cheesy white with redness and itching. Vaginal yeast infections may be related to antibiotics, birth control or other estrogen pills, pregnancy, diabetes, or a weakened immune system.
• Bacterial vaginosis -- an infection that causes a grey discharge and fishy odor that worsen after sexual intercourse.
• Trichomonas -- a sexually-transmitted parasite that causes yellowish-grey or green discharge and intense itching.
• Other infections and sexually transmitted diseases like Chlamydia or gonorrhea.
• Forgotten tampon or foreign body.
