5 Possible Foul-Smelling Vaginal Odor Causes

The list below shows results from the use of our quiz by Buoy users who experienced foul-smelling vaginal odor. This list does not constitute medical advice and may not accurately represent what you have.

Bacterial vaginosis

Bacterial vaginosis is an inflammation of the vagina due to overgrowth of the bacteria which are normally present.

It is not considered an STD (sexually transmitted disease) but nearly all cases are found in women after unprotected sexual contact, especially with multiple partners. Frequent douching is also a factor.

Male partners do not carry this condition, but it can spread between female partners.

Common symptoms include an itchy, foul-smelling discharge that may look grayish or greenish, as well as burning during urination. However, some women have no symptoms.

The greatest risks of bacterial vaginosis are secondary. The symptoms can be similar to actual STDs and so should not be ignored. This condition makes a woman more vulnerable to actual STDs, as well as to pelvic inflammatory disease and to infections following any gynecologic surgery.

Pregnant women with bacterial vaginosis are at risk for premature or low-birth-weight babies.

Diagnosis is made through symptoms, and/or pelvic exam and vaginal swab.

Treatment consists of oral medication, and sometimes a cream or gel that is inserted into the vagina.
