Key takeaways
  • Vaginal discharge is a fluid designed to clean, protect, and lubricate the vagina.
  • Vaginal discharge colors range from clear and white to green, gray, and brown.
  • Hormonal fluctuations, STIs and infections can all lead to different colors of vaginal discharge.
  • You should seek medical advice if your discharge suddenly changes in color and consistency or if it is accompanied by itching or burning.

What vaginal discharge colors mean for your health

Understanding vaginal discharge colors and meaning is essential for every woman at every stage of life. While some colored discharge may indicate infections, others are normal.

White and clear

The first discharge color meaning we’ll discuss is white. White discharge usually is normal and can be due to ovulation, hormonal changes, or healthy bacteria. However, if it’s accompanied by itching, it may indicate a yeast infection, a fishy odor could signify bacterial vaginosis.

Yellow

Yellow vaginal discharge can be either normal or a sign of an underlying issue. A light yellow discharge, particularly if it’s consistent with your body’s normal secretions and isn’t accompanied by any other concerning symptoms, is often nothing to worry about. However, if the discharge is a darker, pus-like yellow and is accompanied by symptoms such as itching, burning, an unusual odor, pain during urination, or pelvic pain, it could indicate an infection or other problem requiring medical attention. Therefore, this color of discharge doesn’t provide immediate clear meaning and may require some additional investigation.

Green

Green vaginal discharge is not considered normal and could be a sign of an underlying infection. It could be caused by vaginal irritation due to minor reasons, however it could also be caused by chlamydia or gonorrhea, or bacterial vaginosis. Different discharge colors like this can also be accompanied by painful urination or intercourse, burning, itching, unpleasant odor, chills, or fever, and should be attended to by a doctor.

Brown

Next up, when discussing discharge colors and meaning is brown. Brown discharge commonly occurs before your period starts and at the end of menstruation when the uterus is cleaning out blood. It’s also normal to see brown discharge around ovulation, with hormonal changes, and as implantation bleeding. However, it could also be a sign of other issues.

Brown discharge could be a sign of STIs like chlamydia; however, this is not the primary symptom. It may also be caused by endometriosis, uterine fibroids, or as a result of a miscarriage. If the brown discharge is accompanied by nausea or vomiting, chills, vaginal bleeding, pelvic or abdominal pain, foul odor, or fever, you should see your doctor.

Gray

The final shade we’ll discuss when covering the different color discharge meaning is gray. Gray discharge is a possible indicator of bacterial vaginosis, an infection caused by overgrowth of normal bacteria. Consult your doctor if it’s accompanied by burning during urination, itching, and a fishy odor.

Healthy vs concerning discharge colors

Healthy discharge is typically clear or white, light yellow, while colors like gray, green, and puss-like yellow could indicate infection. While the color of your discharge is a good way to identify possible underlying issues, it isn’t the only method. The consistency can also give you insights into your health. Normal discharge should vary from watery to thick, depending on where you are in your menstrual cycle.

If it is clumpy or has a cottage cheese-like texture, it could point to a yeast infection. The smell is also a good indicator. Healthy discharge has a slight sweet, musky, or metallic scent, again depending on the stage of your menstrual cycle. Having a strong, unpleasant, fishy odor isn’t normal. Itching, redness, burning, or pain are also signs that point to underlying problems and should be taken seriously.

Common causes of changes in discharge color

Changes in discharge color can be due to numerous reasons, but there are three common causes.

STIs and infection

Infection is one of the main causes of yellow, green, and gray discharge. If left untreated, many of these conditions can lead to serious, long-lasting side effects, so it’s essential to speak to your doctor quickly and not wait for the infection to get worse.

It’s important to note that while hormones significantly influence the amount and texture of discharge, they don’t affect the color, which should remain relatively consistent unless an infection is present. Throughout the menstrual cycle, vaginal discharge naturally changes in consistency and quantity. Right after your period, you may experience minimal discharge and even some vaginal dryness. As you approach ovulation, discharge increases and becomes clearer and more slippery. After ovulation, it typically becomes thicker and the quantity decreases. You’ll likely notice minimal discharge and increased vaginal dryness again just before your next period begins.
