Bacterial vaginosis is a very common vaginal infection. It occurs when bacteria that normally exist in small numbers in the vagina multiply rapidly. Bacterial infection tends to occur in women who have regular sex. The infection does not get passed on to the man.
What causes bacterial vaginosis?
It is estimated, 1 in 3 women will probably get bacterial vaginosis at some time in their life. Once you have had one infection, you are more likely to have a repeat infection.
Bacterial vaginosis occurs when the acidity of the vagina changes, causes of this may include: –
- Sex without a condom, when semen enters the vagina.
- Using too many perfumed soaps or bubble baths.
- Douching (washing out your vagina).
- Using the coil / I.U.D.
The acidity (pH) of the vagina alters at different stages in the menstrual cycle and this may be another reason why the bacteria multiply. However, bacterial vaginosis can develop without any of these causes.
What are the symptoms of bacterial vaginosis?
The main symptom of bacterial vaginosis is usually, a thin white/greyish discharge, which usually has a fishy smell and is usually worse after sex or during a period. Other symptoms may include, irritation or soreness in and around the vagina and on rare occasions itching or swelling may occur. However, itching is more commonly associated with thrush.
