Can a Period Get Rid of Bacterial Vaginosis (BV)?

Bacterial Vaginosis (BV) is a common vaginal condition that arises from a disruption in the natural balance of bacteria within the vagina. A frequent question is whether menstruation can resolve this condition. This article will explore the nature of BV, its interaction with the menstrual cycle, and effective ways to manage and treat it.

Understanding Bacterial Vaginosis

Bacterial Vaginosis occurs when there is an imbalance in the vaginal microbiome, with an overgrowth of certain anaerobic bacteria. Normally, the vagina is rich in beneficial Lactobacillus species, which produce lactic acid to maintain an acidic environment, typically with a pH between 3.8 and 4.5. In BV, these protective Lactobacillus species decrease, allowing other bacteria, such as Gardnerella vaginalis and various anaerobes, to flourish.

This shift causes several symptoms. Common signs include a thin, off-white, gray, or greenish vaginal discharge. A distinctive “fishy” odor is often present, which may become stronger after sexual intercourse or during menstruation. Some individuals may also experience vaginal itching, irritation, or a burning sensation during urination.

The Interplay: Menstruation and BV Symptoms

Individuals often observe a change in their BV symptoms during menstruation, which can lead to the misconception that their period is “curing” the condition. This temporary change is due to physiological shifts in the vaginal environment during the menstrual cycle. Menstrual blood has a pH of approximately 7.4, which is significantly higher than the normal acidic vaginal pH.

The presence of this more alkaline menstrual blood can temporarily raise the overall vaginal pH, making the environment less conducive for the bacteria that cause BV. The physical flow of menstrual blood can also help to wash away some discharge and odor associated with BV, creating a false sense of improvement. Hormonal fluctuations throughout the menstrual cycle can also influence the vaginal bacterial balance, sometimes triggering or exacerbating BV symptoms.

Addressing the Core Question: Can a Period Cure BV?

Despite the temporary relief or masking of symptoms, menstruation does not cure Bacterial Vaginosis. While changes in vaginal pH and blood flow might alleviate some discomfort, the underlying bacterial imbalance persists. The overgrowth of anaerobic bacteria and the reduction of beneficial Lactobacillus species remain unresolved.

The temporary nature of symptom reduction means that once menstruation ends and the vaginal pH begins to return to its typical acidic state, BV symptoms often reappear. BV requires medical intervention to restore the vaginal microbiome. Relying on menstruation to resolve BV can delay appropriate treatment, potentially leading to persistent or recurring infections.

Effective Management and Treatment of BV

Since menstruation does not cure BV, seeking medical advice for diagnosis and treatment is necessary. A healthcare provider can accurately diagnose BV, often through a pelvic exam, by examining vaginal discharge, or by testing vaginal pH. The primary treatment for BV involves prescription antibiotics.

Commonly prescribed antibiotics include metronidazole and clindamycin, available as oral tablets or vaginal gels and creams. Complete the entire course of medication as prescribed, even if symptoms improve before finishing. Stopping treatment early can lead to BV recurrence or incomplete eradication of the bacterial imbalance. To prevent recurrence, avoid douching, use mild, unscented soaps for external cleaning, and practice safe sex.
