About Bacterial Vaginosis (BV)- Bacterial vaginosis (BV) is a common vaginal condition caused by an imbalance in the natural bacteria that normally live in the vagina. It is sometimes referred to as vaginal bacteriosis. Normally, beneficial bacteria, particularly Lactobacillus species, help maintain a healthy vaginal environment. When these protective bacteria decrease and other types of bacteria grow excessively, bacterial vaginosis can develop. Several different bacteria may be involved, including Gardnerella vaginalis. Bacterial vaginosis is common among women of reproductive age. Although it is associated with sexual activity, it is not usually classified as a sexually transmitted infection (STI). However, sexual activity and certain lifestyle factors may increase the risk of developing BV. Some people with bacterial vaginosis have no symptoms. When symptoms occur, the most common complaints include unusual vaginal discharge and a characteristic fishy odor. Early diagnosis and appropriate treatment are important because untreated bacterial vaginosis may increase the risk of certain infections and complications, particularly during pregnancy.
Some women may have bacterial vaginosis without noticing any symptoms. When symptoms are present, they may include:
- Thin, watery, grey, white, or sometimes greenish vaginal discharge
- A strong or unpleasant fishy vaginal odor, which may become more noticeable after sexual intercourse
- Mild vaginal itching or irritation
- Burning or discomfort during urination
- Mild irritation around the vaginal area
It is important to remember that symptoms such as itching, burning, or unusual discharge can also occur with yeast infections and sexually transmitted infections. Therefore, self-diagnosis may not always be accurate.
Bacterial vaginosis develops when the normal balance of bacteria in the vagina is disrupted. A healthy vagina usually contains a large number of beneficial Lactobacillus bacteria. These bacteria help maintain an acidic environment that limits the growth of potentially harmful bacteria. When the number of Lactobacillus bacteria decreases, other bacteria can multiply excessively. This imbalance can lead to bacterial vaginosis. The exact reason why this bacterial imbalance develops is not always known. However, several factors can increase the likelihood of developing BV.
The following factors may increase the risk of bacterial vaginosis:
- Douching, which can disturb the natural balance of bacteria in the vagina
- Cleaning the vagina internally with medicated or chemical solutions
- Having a new sexual partner or multiple sexual partners
- Sexual activity without barrier protection
- Using certain vaginal products that may irritate the area
- Using perfumed soaps, sprays, washes, or other fragranced products in or around the vagina
- Smoking
- Practices or products that disrupt the normal vaginal environment
BV can occur in people who are not sexually active as well.
Bacterial vaginosis is not generally considered a sexually transmitted infection (STI). However, sexual activity can affect the balance of bacteria in the vagina and may increase the risk of developing BV. Having a new sexual partner or multiple sexual partners may increase the likelihood of developing bacterial vaginosis. Because the symptoms of BV can be similar to those of some sexually transmitted infections, it is important to consult a healthcare professional if you experience unusual vaginal discharge, odor, itching, or discomfort.
Diagnosis of Bacterial Vaginosis
A healthcare professional may diagnose bacterial vaginosis based on your symptoms, medical history, and an examination. Diagnostic evaluation may include:
- Discussing your symptoms and medical history
- A pelvic examination
- Examination of vaginal discharge
- Testing the vaginal fluid for changes in acidity (pH)
- Microscopic examination of a sample of vaginal discharge
- Laboratory tests to rule out other infections when necessary
Testing may also be recommended to identify or rule out sexually transmitted infections if there is a possibility of exposure.
Bacterial vaginosis is usually treated with prescription antibiotics. Common treatments may include:
- Metronidazole tablets
- Metronidazole vaginal gel
- Clindamycin cream
- Other medicines prescribed by a healthcare professional
It is important to take the medication exactly as prescribed and complete the full course of treatment, even if symptoms improve before the medication is finished. Do not use leftover antibiotics or take medication prescribed for someone else.Bacterial vaginosis can sometimes return after treatment. Recurrent BV may require further evaluation and treatment by a healthcare professional.
In some cases, bacterial vaginosis may improve without treatment. However, symptoms should not be ignored, particularly if they are persistent, severe, or recurrent. Medical evaluation is especially important during pregnancy or when there is a concern about a sexually transmitted infection.
Untreated bacterial vaginosis may increase the risk of certain health problems. Possible complications include:
- Increased susceptibility to certain sexually transmitted infections
- Increased risk of acquiring HIV if exposed
- Pelvic or reproductive tract infections in certain situations
- Complications associated with some gynecological procedures
- Pregnancy-related complications in some cases
Pregnant individuals with symptoms of bacterial vaginosis should discuss them with their healthcare professional.
Bacterial vaginosis can occur during pregnancy. Pregnant women who experience unusual vaginal discharge, a strong vaginal odor, or other symptoms should consult their healthcare provider. Your doctor can determine whether testing or treatment is necessary and recommend the safest treatment option. Do not use over-the-counter or prescription medicines during pregnancy without medical advice.
It may not always be possible to prevent bacterial vaginosis, but the following measures may help reduce the risk:
- Avoid douching
- Do not wash inside the vagina with soaps or chemical products
- Avoid perfumed sprays, washes, and deodorants in the genital area
- Use gentle, fragrance-free products around the external genital area
- Practice safer sex
- Consider using condoms, particularly with new or multiple sexual partners
- Avoid smoking
- Follow good personal hygiene practices
- Avoid unnecessary use of vaginal cleansing products
The vagina has a natural cleaning mechanism, so internal cleansing products are generally unnecessary.
You should consult a healthcare professional if you experience:
- Unusual vaginal discharge
- A strong or persistent fishy vaginal odor
- Vaginal itching or irritation
- Burning during urination
- Symptoms that do not improve
- Recurrent episodes of bacterial vaginosis
- Symptoms during pregnancy
- Concern about a possible sexually transmitted infection
Prompt medical evaluation can help determine the cause of your symptoms and ensure appropriate treatment.
Bacterial vaginosis is a common vaginal condition caused by an imbalance between the beneficial and other naturally occurring bacteria in the vagina.
The most common symptoms include thin grey or white vaginal discharge and a strong fishy vaginal odor. Some people may also experience itching, irritation, or burning during urination.
Yes. Some people with bacterial vaginosis do not experience noticeable symptoms.
BV is not generally classified as a sexually transmitted infection. However, sexual activity and changes in sexual partners can affect the risk of developing the condition.
Yes. Bacterial vaginosis can usually be treated successfully with prescription antibiotics.
Yes. Recurrence is relatively common, and some people may experience bacterial vaginosis again after successful treatment.
It is best to consult a healthcare professional rather than relying on home remedies. Some products and practices may further disrupt the natural balance of bacteria in the vagina.
No. Douching can disrupt the normal balance of vaginal bacteria and may increase the risk of bacterial vaginosis.
BV may be associated with certain pregnancy complications. Pregnant individuals with symptoms should consult their healthcare provider.
