Bacterial vaginosis (BV) is a common vaginal condition that many women experience. It happens when the balance of bacteria in the vagina is disrupted. Normally, the vagina has a mix of good and bad bacteria. When the bad bacteria grow too much, BV can occur. Many women find that BV keeps coming back, even after treatment. This can be frustrating and confusing. Let’s explore why this happens and what you can do about it.
Understanding Bacterial Vaginosis
Bacterial vaginosis is not an infection caused by a single type of bacteria. Instead, it is an imbalance in the vaginal microbiome. The vagina naturally contains different types of bacteria. Lactobacilli are the good bacteria that help keep the vagina healthy. They produce lactic acid, which keeps the vaginal environment slightly acidic. This acidity helps prevent the growth of harmful bacteria.
When the number of lactobacilli decreases, harmful bacteria can grow. This leads to BV. Symptoms of BV include a fishy odor, grayish discharge, itching, and burning. Some women may not have any symptoms at all. BV is not a sexually transmitted infection (STI), but it can increase the risk of getting an STI.
Why Does BV Keep Coming Back?
Many women find that BV returns after treatment. This is called recurrent BV. There are several reasons why this might happen. Understanding these reasons can help you take steps to prevent BV from coming back.
Incomplete Treatment
One reason BV might come back is that the treatment was not completed. Antibiotics are often used to treat BV. These antibiotics kill the harmful bacteria. However, if you do not finish the full course of antibiotics, some harmful bacteria may survive. These bacteria can then grow back and cause BV again.
It is important to take all the medication prescribed by your doctor. Even if your symptoms go away, you should finish the full course of antibiotics. This helps ensure that all the harmful bacteria are killed.
Reinfection
Another reason BV might come back is reinfection. This can happen if you have sex with a partner who has not been treated. While BV is not an STI, sexual activity can affect the balance of bacteria in the vagina. Semen can change the pH of the vagina, making it less acidic. This can allow harmful bacteria to grow.
Using condoms during sex can help prevent reinfection. Condoms can reduce the risk of introducing new bacteria into the vagina. They can also help maintain the natural pH balance of the vagina.
Imbalance in Vaginal Microbiome
The vagina has a delicate balance of bacteria. Anything that disrupts this balance can lead to BV. Some factors that can disrupt the vaginal microbiome include douching, using scented products, and taking certain medications.
Douching is not necessary for vaginal health. In fact, it can harm the natural balance of bacteria in the vagina. Scented products, such as soaps and sprays, can also disrupt the vaginal microbiome. These products can irritate the vagina and change its pH.
Certain medications, such as antibiotics, can also affect the vaginal microbiome. Antibiotics kill both good and bad bacteria. This can lead to an overgrowth of harmful bacteria. If you need to take antibiotics, talk to your doctor about ways to protect your vaginal health.
Hormonal Changes
Hormonal changes can also affect the vaginal microbiome. Hormones play a role in maintaining the health of the vagina. Changes in hormone levels can lead to changes in the vaginal environment.
For example, during menstruation, the pH of the vagina can change. This can create an environment where harmful bacteria can grow. Pregnancy and menopause can also cause hormonal changes that affect the vaginal microbiome.
Weakened Immune System
A weakened immune system can make it harder for your body to fight off infections. This includes BV. If your immune system is not strong, harmful bacteria can grow more easily.
Certain conditions, such as diabetes and HIV, can weaken the immune system. Stress, lack of sleep, and poor nutrition can also affect your immune system. Taking steps to boost your immune system can help prevent BV from coming back.
Genetic Factors
Some women may be more prone to BV due to genetic factors. Research has shown that certain genetic traits can affect the vaginal microbiome. These traits can make it harder for the body to maintain a healthy balance of bacteria.
If you have a family history of recurrent BV, you may be more likely to experience it yourself. While you cannot change your genetics, you can take steps to reduce your risk of BV.
How to Prevent BV from Coming Back
Preventing BV from coming back involves taking care of your vaginal health. Here are some steps you can take to reduce your risk of recurrent BV.
Practice Good Hygiene
Good hygiene is important for vaginal health. However, this does not mean you need to use special products. In fact, using harsh products can harm the vaginal microbiome.
Wash the vulva with warm water and mild, unscented soap. Avoid douching and using scented products. These can disrupt the natural balance of bacteria in the vagina.
Use Condoms
Using condoms during sex can help prevent BV. Condoms can reduce the risk of introducing new bacteria into the vagina. They can also help maintain the natural pH balance of the vagina.
If you have a new sexual partner, it is especially important to use condoms. This can help reduce the risk of BV and other infections.
Avoid Irritants
Avoid using products that can irritate the vagina. This includes scented soaps, sprays, and feminine hygiene products. These products can disrupt the vaginal microbiome and increase the risk of BV.
Wear cotton underwear and avoid tight-fitting clothing. Cotton allows the skin to breathe and reduces moisture, which can help prevent the growth of harmful bacteria.
Maintain a Healthy Diet
A healthy diet can help support your immune system and overall health. Eating a balanced diet with plenty of fruits, vegetables, and whole grains can help keep your body strong.
Probiotics, which are found in yogurt and other fermented foods, can also help support the vaginal microbiome. Probiotics contain good bacteria that can help maintain a healthy balance in the vagina.
Manage Stress
Stress can weaken the immune system and affect overall health. Finding ways to manage stress can help reduce the risk of BV. This can include exercise, meditation, and getting enough sleep.
Talk to Your Doctor
If you have recurrent BV, it is important to talk to your doctor. Your doctor can help determine the cause of your recurrent BV and recommend treatment options. This may include longer courses of antibiotics or other treatments.
Your doctor may also recommend lifestyle changes to help prevent BV from coming back. This can include changes to your diet, hygiene practices, and sexual habits.
Conclusion
Bacterial vaginosis is a common condition that can be frustrating when it keeps coming back. Understanding the reasons why BV recurs can help you take steps to prevent it. Completing treatment, practicing good hygiene, using condoms, and maintaining a healthy lifestyle can all help reduce the risk of recurrent BV.
If you have recurrent BV, talk to your doctor. They can help you find the best treatment and prevention strategies for your situation. Taking care of your vaginal health is an important part of overall health and well-being.
