Bacterial vaginosis

Regain comfort and relieve symptoms with BV treatments

Bacterial vaginosis (BV) is a common vaginal infection. Usually, healthy bacteria (lactobacilli) maintain balance, but when harmful bacteria grow excessively, it disrupts this harmony, leading to BV.

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

BV is a very common condition. Between 2001 and 2004, 21 million women in the United States aged 14 to 49 years old were reported to experience BV. Continue reading to learn about bacterial vaginosis causes, symptoms and treatment options.

What is bacterial vaginosis?

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.

What causes bacterial vaginosis?

The exact bacterial vaginosis causes are unknown. However, it is thought that most BV infections start with a bacteria called Gardnerella vaginosis. This creates a biofilm that allows other bacteria to grow in the vagina.

How common is bacterial vaginosis?

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.

What are the symptoms of bacterial vaginosis?

Not all women experience BV symptoms when they are infected with it. But symptoms do exist. Here are some common bacterial vaginosis symptoms:

  • unusual white or gray vaginal discharge
  • a strong fishy vaginal odor (especially after intercourse)
  • vaginal itching or irritation
  • burning when urinating

Bacterial vaginosis symptoms may be similar to other infections, such as yeast infections or sexually transmitted infections (STIs). Because of these similarities, it is important to get a proper diagnosis from a healthcare professional.

Who is at risk of getting bacterial vaginosis?

There are certain risk factors that may increase your chances of getting BV, these include:

  • Being sexually active
  • Having unprotected sex
  • Vaginal douching
  • Having new or multiple sex partners
  • Inserting herbs or other products into the vagina
  • Cigarette smoking
  • Poor genital hygiene

BV rarely affects those who have never had sex. The infection cannot be spread from toilet seats, bedding, or swimming pools.

How is bacterial vaginosis diagnosed?

To diagnose bacterial vaginosis, a healthcare professional may:

  • Ask you questions about your symptoms, medical and sexual history, including any vaginal infections or STIs you've had in the past.
  • Perform a genital exam which includes taking a look in and feeling around the vagina for signs of an infection.
  • Take a sample of your vaginal discharge to check for the bacteria and to test your vaginal pH.

Make sure to answer the questions about bacterial vaginosis in our online consultation form accurately to the best of your abilities. Doing so will help us give you a proper diagnosis for your condition.

What happens if bacterial vaginosis is left untreated?

BV is a common condition and does not usually cause serious problems. However, untreated bacterial vaginosis could lead to:

  • Increased risk of getting STIs, such as HIV, genital herpes, chlamydia, and gonorrhea.
  • Pelvic inflammatory disease (which can make it difficult for you to have children later on)
  • Pregnancy problems such as premature birth, spontaneous abortion, or having a low-birth-weight baby.

This is why it is recommended to get treated as soon as possible.

How can I prevent bacterial vaginosis?

To reduce your risk of getting BV and protect the normal balance of bacteria in the vagina, do the following:

  • Avoid douching as this changes the natural balance of bacteria in the vagina
  • If you use sex toys, make sure they are properly cleaned after every use
  • Limit your number of sexual partners
  • Use condoms or dental dams during sexual activity
  • Wear breathable cotton or cotton-lined underwear that protects against moisture
  • Avoid tight clothing as this can trap heat and moisture, creating an environment where harmful bacteria may grow
  • Avoid using perfumed soaps, bubble bath, or strong detergents near your genital area
