About Bacterial Vaginosis
The exact cause of BV is still unclear, but several factors contribute to its development. These may include:
- Reduction of protective bacteria in the vagina
- Overgrowth of harmful bacteria
- Presence of other bacteria
Risk factors of bacterial vaginosis include:
- Multiple sexual partners
- Decreased Lactobacillus (protective bacteria) species
- Concurrent colonization with Candida species
- Hormonal changes (menopause)Smoking
- Poor hygiene practices
- Use of intrauterine devices (IUDs)
- Douching or using vaginal sprays
It's important to note that these risk factors increase the likelihood of developing BV, but they do not guarantee its occurrence. If you suspect you have BV or want to learn more about prevention strategies, it's best to consult with your healthcare professional.
The most common early symptoms of BV include:
- Discomfort in the vaginal area
- Unusual discharge, which may be thin, white, or gray
- Strong odor, often described as fishy
As BV progresses or becomes more severe, additional symptoms may occur:
- Itching around the vagina
- Burning sensations during urination
- Pain or burning during and after sex
It's important to note that some people with BV may not experience any symptoms at all. BV can also be mistaken for a yeast infection, but BV is typically characterized by a foul odor and greenish, yellow, or gray discharge.
If you suspect you have BV or are experiencing any of these symptoms, it's important to see a healthcare professional for an accurate diagnosis and appropriate treatment.
To diagnose BV, healthcare professionals commonly perform the following examinations, tests, and procedures:
- Medical history: A healthcare professional will take your medical history, including any symptoms you may be experiencing.
- Physical pelvic exam: A healthcare professional will perform a physical pelvic exam to assess the vaginal area for any signs of infection or inflammation.
- Sample collection: A sterile swab is used to collect samples from the vaginal. These samples can be used for further testing.
- Lab-based testing: The collected samples can be analyzed in a laboratory using various techniques to determine the presence of BV. This may include examining vaginal cells, checking vaginal acidity, and analyzing bacterial byproducts.
Additional examinations, tests, and procedures to determine the stage or severity of BV may include:
- Clinical criteria: Amsel's criteria are commonly used clinical standards to diagnose BV. It includes assessing factors such as vaginal pH, presence of clue cells in vulval fluid, whitish milky uniform vulval secretion, and amine fish-like odor upon adding potassium hydroxide (KOH) to the vulval discharge.
- Evaluation for other illnesses: To rule out other potentially dangerous conditions and evaluate the severity of BV, healthcare professionals may assess for fever, pelvic discomfort, and a history of sexually transmitted infections.
It's important to note that new diagnostic methods are being developed based on biomarkers from vaginal microbiome and metabolome data. These advancements may offer more sensitive and specific point-of-care tests in the future. Remember to consult with a healthcare professional for accurate diagnosis and evaluation of BV.
The goals of treatment for BV are to eliminate the infection, restore the balance of the vaginal flora, and prevent recurrence. Here are some recommended treatments and how they work to achieve these goals:
Medications:
- Antibiotics: Depending on the specific bacteria involved, individualized antibiotic treatment may be recommended to effectively eliminate the infection. They work by killing the bacteria causing the infection.
- Probiotics: Oral or vaginal probiotic supplementation is used to increase the presence of beneficial bacteria in the vagina, promoting a healthy vaginal environment.
Health behavior changes:
- Avoiding douching: Douching disrupts the natural balance of vaginal bacteria and can worsen BV. It is recommended to avoid douching.
- Safe sexual practices: Using condoms during sexual activity may help reduce the risk of BV recurrence.
Other Treatments:
- Lowering vaginal pH: Estrogen, lactic acid, or boric acid may be used to lower vaginal pH, creating an environment less favorable for harmful bacteria.
It's important to consult with your healthcare professional before starting any medication or making health behavior changes. They can provide personalized advice and determine the most appropriate treatment approach for you. Medication dosing may be affected by many factors. Talk with a healthcare professional about specific medication dosing and potential side effects.
