Bacterial vaginosis may change the normal vaginal discharge by causing a “fishy” odor. It can also cause vaginal irritation.

Bacterial vaginosis occurs when there is an imbalance of bacteria that live in the vagina. A healthy vagina contains a variety of bacteria. Typically, these bacteria are balanced however, sometimes, the bad bacteria can overgrow and outnumber the good bacteria. This leads to infections, such as BV.

Bacterial vaginosis is the most common vaginal condition in women aged 15 to 44. According to the World Health Organization, globally, 23–29% of women of reproductive age are affected.
This is because, during these years, the changes in hormone levels make it easier for certain strains of bacteria to grow.
Not all women experience BV symptoms when they are infected with it. But symptoms do exist. Here are some common bacterial vaginosis symptoms:
