Bacterial Vaginosis

Updated: Sep 30, 2018

Last week we spoke about candida. This week I would like to talk about another common cause of vaginitis: BACTERIAL VAGINOSIS (BV).

BV is a result from a change in the microorganism in the vagina, predominantly the lactobacilli. The change of the microorganism results in an increase of the vagina PH from a normal range to 4-4.5 to >4.5 and this cause the characteristic fishy odour of BV.

BV it is not usually categorized as a sexually transmitted infection (STI) but people with an STI are at increased risk of BV.

Other things that can increase BV are:

· Vaginal douching

· Bubble bath

· Copper intrauterine device

· Some evidence that smoking may increase risk of BV

In pregnant women BV is associated with late miscarriage and preterm delivery. It can also cause postpartum fever, post abortion infection.

For some wome BV can goes away without treatment. If it is not Treatment with Metronidazole usually results in a cure in 70-80% of cases.

However, recurrence is seen up to 70% of women within the 3months treatment. To those women who have recurrence for four or more times a year or not responding to treatment they are advice to attend gynecologist of a genitourinary medicine specialist.

At the moment there is a study called VITA that is investigating a different treatment for people with recurrent BV.

If you are not sure that you have BV and you have symptoms attend your doctor, midwife or a GUM clinic to have test done and receive some advice.
