Understanding White Vaginal Discharge: Causes & What's Normal

Vaginal discharge is a normal part of a woman's reproductive health. It is a mucus-like fluid that is produced by the glands of the vagina and cervix. The amount, color, and consistency of vaginal discharge can vary throughout a woman's menstrual cycle.

White discharge is often a sign of ovulation, which occurs when an egg is released from the ovary. Estrogen levels rise just before ovulation, causing the discharge to become thicker and more egg-white in consistency. This type of discharge is also called egg-white cervical mucus (EWCM).

Other causes of white discharge include:

- Pregnancy: Increased levels of progesterone during pregnancy can cause the discharge to become thicker and whiter.

- Infections: Some sexually transmitted infections (STIs), such as chlamydia and gonorrhea, can cause white discharge. Bacterial vaginosis (BV) is another common infection that can cause white discharge, often with a fishy odor.

- Yeast infections: Yeast infections are caused by an overgrowth of Candida, a type of yeast that normally lives in the vagina. Symptoms of a yeast infection include white discharge that is thick, clumpy, and resembles cottage cheese.

- Hormonal imbalances: Hormonal imbalances, such as those caused by thyroid problems or menopause, can cause changes in the color, consistency, and amount of vaginal discharge.

It is important to see a doctor if:

- The white discharge is accompanied by other symptoms, such as itching, burning, or pain during urination or sex.

- The discharge has a foul odor.

- The discharge is unusually heavy or persistent.

- You are not sure what is causing the discharge.
