Bacterial vaginosis is a mismatch of the vaginal flora. Normally in healthy women the vaginal flora is dominated by lactobacillus. There are many different lactobacilli species responsible for mantaining a healthy environment in the vagina. If lactobacilli disappear there is an overgrowth of mostly anaerobic bacteria like Gardnerella, Prevotella, Mobiluncus which cause a vaginal discharge and bad odor or sometimes also vaginal and/or lower abdominal pain.
Bacterial vaginosis is not a sexually transmitted disease. It is caused though a complete loss of lactobacilli, which are responsible for a normal, healthy vaginal environment.
Due to new data of scientific research we know today, that the intestinal tract is a reservoir for lactobacilli. From studies we know that lactobacilli colonize the intestinal tract. Especially the rectum and anus are colonized by lactobacilli as well as the vagina. If there is a lactobacillus loss in the intestinal tract then there is a high risk for bacterial vaginosis. Loss of lactobacilli in the rectum are associated with frequently recurrent bacterial vaginosis.
There is the possibility to support the vagina with lactobacilli either locally or orally. New scientific data shows that the vaginal lactobacillus flora vagina can be enriched with lactobacilli.
