Is bacterial vaginosis the same as a yeast infection?

No, bacterial vaginosis (BV) is not the same as a yeast infection. These are two completely different conditions, although they both fall under the umbrella of vaginitis and can cause similar vaginal symptoms. They differ in their cause, characteristic symptoms, and specific treatment methods. Understanding these differences is essential for receiving the correct diagnosis and appropriate treatment.

What is bacterial vaginosis?

Bacterial vaginosis is a common condition that occurs due to an imbalance in the natural balance of bacteria in the vagina. Normally, the vagina contains various types of bacteria, some beneficial and some harmful. When harmful bacteria overgrow, this imbalance occurs. Bacterial vaginosis is the most common vaginal infection among women aged 15-44 [1].

Symptoms of bacterial vaginosis

• Thin white or gray vaginal discharge [1].
• A strong odor resembling fish, especially after intercourse or during menstruation [2].
• Itching or burning in the vagina, although this is not always common [3].
• Some women with bacterial vaginosis may not experience any symptoms [1].

What is a yeast infection?

A yeast infection, or candidiasis, is a condition that occurs as a result of the overgrowth of a fungus called Candida in the vagina. This fungus exists naturally in the body, but certain factors can lead to its overgrowth, causing an infection [1].

Symptoms of a yeast infection

• Thick, white vaginal discharge, which may resemble cottage cheese [1].
• Severe itching and redness in the vagina and vulva [1].
• Burning, which may worsen during urination or intercourse [2].
• The discharge is usually odorless [1].

Causes and key differences

The factors that increase the risk of developing each condition differ:

• Bacterial Vaginosis: Antibiotics, douching, intrauterine device (IUD) use, or having unprotected sex with new or multiple partners can increase the risk of developing it [1]. Although it can occur without sexual activity, factors such as douching and having multiple partners increase the risks [3].
• Yeast Infection: Antibiotics, pregnancy, poorly controlled diabetes, and steroid medications increase the risk of yeast overgrowth [1].

Diagnosis and treatment

Given the differences in causes, the diagnosis and treatment for each condition vary:

• Diagnosis: The doctor will take a medical history, perform a pelvic exam, and examine a sample of vaginal discharge under a microscope to determine the type of infection [1]. It is important not to use any vaginal medications, douche, or have sexual intercourse for at least 3 days before visiting the doctor to ensure accurate results [2].
• Bacterial Vaginosis Treatment: It is treated with antibiotics, which may be in the form of oral tablets or creams or gels inserted into the vagina [1]. It is important to complete the full course of treatment even if symptoms disappear [2]. Bacterial vaginosis may recur even after treatment [3].
• Yeast Infection Treatment: It is usually treated with antifungal creams or medications inserted into the vagina, or sometimes with a single dose of an oral medication [2]. Over-the-counter treatments are available, but it is advised to consult a doctor before using them, especially if this is the first time symptoms have appeared [1].

Next steps and when to seek help

If you are experiencing any vaginal symptoms such as unusual discharge, itching, burning, or a foul odor, it is essential to visit a doctor to determine the exact cause. Self-diagnosis can lead to incorrect treatment and delayed recovery [2]. You should not use douches or vaginal sprays because they can alter the natural balance of bacteria in the vagina [1]. It is important to treat bacterial vaginosis and yeast infections, as leaving them untreated may increase the risk of acquiring HIV or other sexually transmitted diseases [1]. If you are pregnant, bacterial vaginosis can increase the risk of preterm birth or low birth weight [3].
