Overview
Bacterial vaginosis is the most common microbial disturbance of the vaginal flora in women of childbearing age. The natural lactic acid bacteria (lactobacilli) fall out of balance and are displaced by other bacteria, above all Gardnerella vaginalis. Typical signs are an increased, thin, grey-white discharge and an unpleasant, fishy odour that is often more noticeable after sexual intercourse. However, about half of those affected notice no or only mild symptoms. Bacterial vaginosis is not a classic sexually transmitted disease, but sexual activity can promote its development. Left untreated, it can increase the risk of ascending infections and of complications in pregnancy. Treatment is usually with antibiotics such as metronidazole or clindamycin, as tablets or for vaginal use. At OpenClinic24 you describe your symptoms in a structured medical history questionnaire and then discuss them in a video consultation. Following the medical assessment, a private prescription can be issued, provided treatment via telemedicine is appropriate.
Common causes
Bacterial vaginosis develops when the acidic environment of the vagina is disturbed and the protective lactobacilli decline. Contributing factors include frequent or new sexual partners, unprotected intercourse, excessive intimate hygiene with vaginal douching or perfumed products, and hormonal changes, for example during menstruation, pregnancy or the menopause. A copper coil, smoking, persistent stress and antibiotic treatment for other reasons can also affect the balance of the vaginal flora. If the vaginal pH rises, bacteria such as Gardnerella vaginalis can multiply strongly and form a biofilm on the vaginal wall. This biofilm also explains why bacterial vaginosis recurs in some of those affected after initially successful treatment. Transmission in the strict sense, for example via toilets or swimming pools, is considered very unlikely.
When to see a doctor
Seek medical advice if you notice altered discharge with an unpleasant odour for the first time, or if symptoms persist despite treatment or keep coming back. You should visit a gynaecological practice in particular if you are pregnant, develop a fever, have lower abdominal pain, intermenstrual bleeding or pain during intercourse, or if a sexually transmitted infection is suspected. These situations require a physical examination and cannot be conclusively assessed via telemedicine. Warning signs of a serious complication are high fever with chills, severe or increasing lower abdominal pain, purulent discharge and feeling distinctly unwell; in these cases you should be examined by a doctor on the same day. If there are signs of circulatory failure, such as confusion, a very rapid heartbeat or impending loss of consciousness, call the emergency number 112 immediately.
