When dealing with bacterial vaginosis, an imbalance of vaginal bacteria that leads to discharge, odor, and irritation. Also called BV, it affects many women worldwide. The condition is closely linked to the vaginal microbiome, the community of microorganisms that normally protect the vagina, especially the loss of Lactobacillus, beneficial bacteria that keep acidity low. Restoring balance often involves antibiotics, drugs that kill harmful bacteria or probiotics, supplements that re‑introduce good microbes. Below we unpack how it shows up, how doctors confirm it, and what you can do to feel better.
Typical signs include a thin, gray‑white discharge and a distinctive fishy smell that gets stronger after sex. Many women notice an elevated vaginal pH above 4.5, which signals an environment that favors bad bacteria. Doctors rely on the Amsel criteria – a checklist that looks at discharge, odor, pH, and the presence of clue cells – or the Nugent score, a lab‑based grading of bacterial patterns. The whiff test, where a drop of potassium hydroxide reveals the odor, is another quick clue. Spotting these signs early helps avoid lingering discomfort.
Why does the balance tip? A drop in Lactobacillus crispatus, the most protective strain, raises the pH and lets anaerobes like Gardnerella vaginalis flourish. Sexual activity with a new partner, frequent douching, or using scented soaps can disturb the flora. Even recent courses of antibiotics for unrelated infections may wipe out good bacteria, giving the bad ones a foothold. Hormonal shifts during the menstrual cycle also play a role, making some weeks more vulnerable than others.
Treatment usually starts with metronidazole or clindamycin, offered as an oral pill or a vaginal gel. A typical metronidazole course lasts seven days, while a clindamycin gel is applied once daily for five days. Tinidazole is another oral option for those who can’t tolerate metronidazole. Side effects can include nausea, a metallic taste, or mild irritation, and resistance is an emerging concern, so doctors may adjust the regimen based on response.
Many turn to probiotics after antibiotics to keep the good bacteria in check. Strains such as Lactobacillus rhamnosus GR‑1 and Lactobacillus reuteri RC‑14 have shown promise in clinical trials, reducing recurrence rates. Eating yogurt with live cultures, kefir, or fermented vegetables supplies natural prebiotics that feed these microbes. Some women use probiotic tablets designed for vaginal health, inserting them at night for a week or two to boost colonization.
Preventing a future episode is often about simple habits. Using condoms during sex lowers the chance of swapping bacteria, and avoiding douching eliminates a major disruptor of the vaginal ecosystem. Regular pelvic exams help catch changes early, especially if you’re pregnant or have a history of repeat BV. A balanced diet rich in fiber and low in added sugars supports overall microbiome health, while managing stress can keep hormone spikes in check.
Why take BV seriously? In pregnancy, untreated bacterial vaginosis raises the risk of preterm birth and low birth weight. It can also make it easier to acquire other sexually transmitted infections and, in rare cases, contribute to infertility. Post‑menopausal women may experience more severe symptoms because estrogen levels no longer support Lactobacillus growth. Immunocompromised patients should be extra vigilant, as infections can spread more easily.
