Bacterial vaginosis is a disease that is characterized by the appearance of unpleasantly smelling heavy whiter in the absence of pathogens (gonococci, trihomanady, candida, etc.), as well as by the lack of visual signs of inflammation of the mucous membrane of the vagina.

Bacterial vaginosis is caused by imbalance of microflora in the vagina. Normally, it is represented primarily by lactobacilli. These bacteria form lactic acid and hydrogen peroxide, preventing the multiplication of opportunistic microorganisms. The structure of the normal microflora of the vagina in small quantity may include Gardnerella vaginalis, Mycoplasma hominis and anaerobic bacteria (genus Mobiluncus, and others). These microorganisms are present in small amounts in the vagina of most healthy women.

As a result of douching, use of contraceptives containing nonoxynol 9, change of sexual partners, the proportion of lactobacilli decreases in the microflora of the vagina. At the same time the level of Gardnerella vaginalis, Mycoplasma hominis and anaerobic bacteria increases. This leads to vaginal disbacteriosis - the so-called bacterial vaginosis.

The first step is to suppress the excessive amount of bad bacteria, the second – to introduce the good ones. For this reason, first must be used drugs against anaerobic bacteria like metronidazole or clindamycin in the form of suppositories and gels, and sometimes systemically in the form of tablets. Vaginosis is not sexually transmitted, therefore only the woman should be treated. The 2nd phase is to input lactobacilli by a special diet rich with these bacteria, e.g. yogurts, and additional medicines containing lactobacilli.
