Bacterial vaginosis, often called BV, is a common vaginal infection. Many people wonder about the causes of bacterial vaginosis. Knowing what causes BV can help you understand your own risk. This guide explains the main causes and risk factors for bacterial vaginosis in simple terms. All information comes from trusted sources like the CDC and WHO.
What Is Bacterial Vaginosis?
Before we look at the causes, it helps to know what BV is. Bacterial vaginosis happens when the balance of bacteria in the vagina changes. Usually, good bacteria keep the vagina healthy. But sometimes, harmful bacteria grow too much. This change can lead to BV.
Imbalance of Vaginal Bacteria
Most cases of BV start with a change in the normal bacteria. Normally, the vagina has more good bacteria called lactobacilli. However, when these decrease, other bacteria can grow. As a result, this imbalance is the main cause of BV.
According to the CDC, this imbalance is the root cause of bacterial vaginosis.
Sexual Activity and New Partners
Although BV is not a sexually transmitted infection, sexual activity can affect your risk. For example, having a new sex partner or multiple partners can change vaginal bacteria. Because of this, women who are sexually active may have a higher risk of BV.
Still, you can get BV even if you are not sexually active.
Douching and Use of Vaginal Products
Some women use products to clean the vagina, such as douches or sprays. However, these products can upset the natural balance of bacteria. For instance, douching washes away good bacteria. Because of this, the risk of BV goes up.
The CDC advises against douching for this reason.
Lack of Lactobacilli
Lactobacilli are good bacteria that protect the vagina. Sometimes, women have fewer lactobacilli for reasons that are not clear. As a result, they may be more likely to get BV. This lack of good bacteria is a key risk factor for bacterial vaginosis.
Other Risk Factors for Bacterial Vaginosis
Besides the main causes, some other things can raise your risk. For example, certain habits or health conditions may play a role. While these do not directly cause BV, they can make it more likely.
Additionally, some women may be more prone to BV for reasons doctors do not fully understand.
Summary
In short, the causes of bacterial vaginosis include changes in vaginal bacteria, sexual activity, douching, and a lack of good bacteria. Other risk factors for bacterial vaginosis, like smoking or not using condoms, may also play a part. However, BV can happen to anyone.
