Bv positive means that you have bacterial vaginosis, which can be treated with medication under a doctor’s supervision. Some bacteria live in the vagina, including lactobacilli, which are the main group of bacteria that inhibit other bacteria and protect the vagina. BV is the abbreviation of bacterial vaginosis, which is generally believed to be caused by bacterial dysbiosis, resulting in a decrease in lactobacilli, which allows other bacteria to thrive. Some patients are asymptomatic, while some have abnormal leukorrhea, odor, and varying degrees of itching or burning sensation. Patients can be treated with medication under the guidance of a doctor, either by applying metronidazole or clindamycin cream to the vagina, or by taking metronidazole or clindamycin orally, of which the oral effect is more effective.
