Green Vaginal Discharge Symptoms Explained
Vaginal discharge is a mixture of cells and bodily fluid excreted through the vagina, part of a healthy female body. Vaginal discharge can vary in amount, color, and consistency, but the quantity and quality of vaginal discharge often change depending on the stage of your menstrual cycle [1]. Nevertheless, vaginal discharge that differs significantly, as in odor or appearance, may be a sign of an underlying problem.
Common accompanying symptoms
For example, your discharge may appear green or brown instead of white or clear. Along with a change in color, you may also experience the following.
- Vaginal pain
- Vaginal irritation and itching
- Increased frequency of urination [2]
- Burning with urination [2]
- Bleeding or pain with sexual activity
Why is My Vaginal Discharge Green?
Causes of abnormal vaginal discharge are often readily diagnosed and treatable. The following details may help you better understand your symptoms and if and when you need to see a physician.
Infectious causes
The female reproductive system is open to the environment via the vagina, making it particularly susceptible to infection by outside organisms or those already present [3,4].
- Bacterial: Bacteria that normally inhabit the vagina can overgrow and cause an infection that leads to abnormal vaginal discharge. Furthermore, sexually transmitted bacteria, such as gonorrhea and chlamydia, can cause similar symptoms [3].
- Fungal: Yeast is a type of fungus present in the vagina. When yeast increases, it can overgrow and cause an infection that results in vaginal itching and abnormal discharge [4].
Other causes
Other causes that can result in green vaginal discharge include the following [5,6].
- Obstructive: Any object inserted into the vagina that can obstruct the flow of vaginal fluid may result in abnormal vaginal discharge. Tampons left in the vagina for too long are often a frequent offender.
- Topical: Certain scented sprays and soaps and hygiene practices, such as douching, can disrupt the vaginal fluid balance and result in abnormal vaginal discharge.
- Anatomical: Rarely, an abnormal anatomical opening between the vagina and the rectum (called a fistula) allows feces to leak into the vagina, resulting in what may appear to be brown discharge with a foul odor.

Pelvic inflammatory disease
Pelvic inflammatory disease, or PID, is the general term for a bacterial infection of a woman's reproductive organs.
PID is most often a complication of a sexually transmitted disease (STD) such as gonorrhea or chlamydia. However, it is possible to get PID from other causes.
Any woman can be affected. It is most often found in sexually active women under age 25, especially those who have had PID before, have multiple partners, and/or douche frequently.
Symptoms include fever, lower abdominal pain, foul-smelling vaginal discharge, pain and/or bleeding during sex, and pain on urination.
Untreated PID can cause infertility due to damaged tissue in the reproductive tract, as well as chronic pelvic and abdominal pain. Unprotected sex partners will be infected as well.
Diagnosis is made through symptoms, pelvic examination, vaginal and cervical swabs, and urine tests.
Treatment is with a course of antibiotics. Be sure to finish all of the medication as directed, even when you begin feeling better.
To prevent PID, have all partners (male or female) tested for STDs and avoid unprotected sexual contact.
Rarity: Common
Top Symptoms: fever, abdominal pain or unusual vaginal discharge, vaginal discharge, nausea or vomiting, vaginal bleeding, pelvis pain
Symptoms that always occur with pelvic inflammatory disease: fever, abdominal pain or unusual vaginal discharge
Urgency: In-person visit

What color is the discharge from a bacterial infection?
Bacterial infection can result in a discharge of many colors. If the infection is from a sexually transmitted infection (STI), your discharge may be yellow, white, red, or grey.

Which STD causes green discharge?

If you have trichomonas vaginalis, it's also likely to have concurrent gonorrhea or chlamydia. See a physician for proper treatment of these conditions [8].
Why do I have smelly green discharge?
A smelly (fishy) green discharge is a common sign of an infection with Trichomonas vaginalis. This infection is caused by sexual activity with another infected person through contact of mucous membranes. It transmits through vagino-vaginal contact or penile-vaginal contact since it tends to colonize the genitals [8].
Is light green discharge normal during pregnancy?
