Bacterial Vaginosis vs. Yeast Infection, What's The Difference?

Many conditions can lead to vaginal inflammation resulting in itching, burning sensation, abnormal discharge, and foul odor. While bacterial vaginosis vs. yeast infection is often confused, they are very different in their cause, symptoms, treatment, and prevention.

When an imbalance in the vaginal flora is caused by bacteria overgrowth, it is commonly called bacterial vaginosis. On the other hand, yeast infections are usually attributed to many fungus species known as Candida albicans.

Many women think that the two conditions are similar, requiring antifungal treatment. It's a wrong idea as yeast infections can be easily treated with over-the-counter creams and vaginal suppositories. In addition, most women confuse bacterial vaginosis symptoms with those of sexually transmitted infections such as gonorrhea. It should not be the case as bacterial vaginosis does not cause pelvic inflammatory diseases.

What Is a yeast infection and bacterial vaginosis?

It is caused by an overgrowth of harmful bacteria in the vagina. Bacterial vaginosis generally does not affect a woman's health. It is considered a normal reaction of the body to maintain vaginal health. This condition can be seen in women who have had unprotected sex with multiple partners and those who have diabetes. Bacterial vaginosis also occurs due to using an intrauterine device (IUD). In addition, these vaginal infections are common in women who wear tight and synthetic undergarments and those using scented soaps and body washes.

Yeast Infection

Although yeast infections are not categorized as STIs, they may lead to complications of the reproductive system if not treated. The condition is commonly caused by excessive fungus in the vagina. Most of the time, this fungus is Candida albicans which naturally lives in healthy intimate areas of women. When there is an overgrowth or imbalance of this fungus, yeast infection is the result. According to leading experts, women with bacterial vaginosis are more at risk of getting a yeast infection than those who do not have bacterial vaginosis.

Bacterial Vaginosis vs. Yeast Infection Symptoms

Vaginal yeast infection vs. bacterial vaginosis symptoms are often hard to distinguish. However, there are particular symptoms that women can look for to determine the type of infectious process that is affecting their intimate areas.

Bacterial Vaginosis

  • The vaginal burning sensation is caused by the acidic pH level in the vagina
  • Muscular pain in the lower abdomen
  • Lower back pain during menstruation
  • Cloudy, grey, or white thin vaginal discharge

  • Burning sensation in the vaginal opening
  • Mild to severe pain during sexual intercourse
  • Itching and irritation in the external genitalia
  • Dull, constant ache in lower abdomen or backache. The intensity of this pain increases during menstruation. Usually, there is no fever present. However, it may occur if the infection spreads to the fallopian tubes and ovaries.

  • Sexual intercourse with a male partner who has had many other sexual partners or whose sexual health status is otherwise unclear
  • Using antibiotics or birth control pills
  • Diabetic women who experience frequent yeast infections
  • Women with weakened immune systems, such as those with HIV/AIDS and those receiving cancer treatments.
