Causes:

BV occurs when the balance of bacteria in the vagina is disrupted. Normally, the vagina contains a balance of "good" bacteria (Lactobacillus species) and other bacteria.
When there's an overgrowth of harmful bacteria such as Gardnerella vaginalis, BV can develop.

Symptoms:

BV symptoms may include:
A thin, white or gray vaginal discharge;
A strong fishy odor (especially after sex);
Itching or irritation in the vaginal area and;
Sometimes burning during urination.

However, some women with BV may not experience any symptoms.
