What to expect if you are diagnosed with bacterial vaginosis, inluding treatment options and recurrences
Bacterial vaginosis is the result of a major change in the types and numbers of bacteria usually found in the vagina. Changes in the normal acidity of the vagina are accompanied by an overgrowth of several different kinds of bacteria which are normally present in only very small numbers. These bacteria replace the normal protective vaginal bacteria (lactobacilli).
It used to be thought that bacterial vaginosis was caused by overgrowth of bacteria called Gardnerella vaginalis, but it is now recognised that these bacteria occur in many women who have no symptoms, and attempting to grow them from vaginal secretions is no longer recommended.
Bacterial vaginosis is not considered to be a sexually transmitted disease, although it is associated with sexual activity.
Painful intercourse and genital itch do not commonly occur with this condition.
Diagnosis is made by a vaginal examination and a microscopic examination of a sample of the vaginal discharge.
(time between becoming infected and developing symptoms)
The cause is not yet understood, so the time between whatever changes cause bacterial vaginosis and development of symptoms is unknown.
(time during which an infected person can infect others)
Not transmitted to sexual partners.
Bacterial vaginosis is not usually treated unless symptoms are a problem. Several treatments are available, both vaginal creams and tablets. Women with bacterial vaginosis may be at slightly increased risk of complications in pregnancy and of developing infections after gynaecologic surgery and should discuss the need for treatment with their doctor.
Vinegar or Aci-Jel vaginal jelly help to relieve symptoms but are not useful for treatment or prevention.
Sexual partners do not need to be treated.

Avoid vaginal douching, use of shower gel, use of antiseptic agents and shampoo in the bath.
