Causes of bacterial vaginosis

The most common disease in the vagina is vaginitis, and bacterial vaginitis is one of them. So, what factors lead to the occurrence of bacterial vaginitis? Let's learn about the causes of bacterial vaginitis from the following article.

1. Under the action of endocrine hormones, vaginal epithelial cells of normal women of childbearing age proliferate, and the surface cells contain rich glycogen, which is very conducive to the growth of facultative lactobacilli. This type of bacterial vaginitis accounts for more than 90% of vaginitis. The presence of a large number of lactobacilli inhibits the growth of other pathogenic bacteria. Therefore, this is one of the causes of bacterial vaginitis.

2. When the estrogen level in the human body decreases, the vaginal epithelium atrophies and the cell glycogen decreases, which is not conducive to the growth of lactobacilli. The large-scale use of antibiotics or excessive flushing of the vagina with alkaline liquids inhibits the growth of lactobacilli. This is also the cause of bacterial vaginitis. Frequent sexual intercourse between couples leads to the proliferation of pathogenic anaerobic bacteria and Gardnerella, causing the imbalance of the vaginal microbial ecological balance. The reduction of facultative aerobic lactobacilli ultimately leads to bacterial vaginitis.

3. The decarboxylase produced by anaerobic bacteria can stimulate Gardnerella to produce certain amino acids, produce volatile amines, and release unpleasant fishy odor. Amines increase the pH value and inhibit the reproduction of lactobacilli. The vaginal epidermal cells with bacteria attached fall off, increasing vaginal secretions, thus leading to the appearance of bacterial vaginitis. Therefore, this is also the cause of bacterial vaginitis.

The above is a detailed description of the causes of bacterial vaginitis. I hope it can help everyone understand the knowledge of vaginitis and cure it in time. If you have other questions about vaginitis, you can contact our online experts to answer your questions.
