Patient's question:
Vaginal itching, bad odor, previously had vaginitis, feeling it has recurred again. What is bacterial vaginosis?Doctor's answer:
Hello, bacterial vaginosis is primarily a type of vaginitis caused by Gardnerella vaginalis and can be spread through sexual contact. Bacterial vaginosis is a disease that arises when Gardnerella, anaerobic bacteria, and other microorganisms increase, while lactobacilli decrease, leading to a disruption in the ecological balance of the vaginal system. It is worth noting that healthy women's vaginas also contain Gardnerella. When estrogen levels rise in the body, the vaginal epithelium swells, and glycogen production increases, which is beneficial for lactobacilli growth. However, excessive use of antibiotics or over-washing the vagina with alkaline liquids can inhibit lactobacilli growth, allowing pathogenic anaerobic bacteria to proliferate. This disrupts the vaginal microbial ecological balance and leads to endocrine disorders, resulting in bacterial vaginosis. It is recommended to use medication under the guidance of a doctor. Wishing you a speedy recovery.
