Bacterial vaginosis (BV)

Unusual intimate odour and discharge? It could be Bacterial Vaginosis or BV.

Thrush gets all the attention, but bacterial vaginosis is actually more common among women of reproductive age. If you are a woman and between 15 and 45 years of age, you are in the group that’s most at risk of bacterial vaginosis (or BV in short). BV is the most common cause of vaginal infections, and fortunately can be easily treated.

Your vagina is normally acidic, which helps prevent bad bacteria from growing and maintains the level of good bacteria called lactobacillus. If the pH balance becomes less acidic however, this can affect the health of your vagina. Different factors can affect the pH balance of your vagina, including getting your period, taking antibiotics, over-washing, using an IUD (intrauterine device) and semen if you have sex without a condom. The imbalance of your pH can be accompanied by overgrowth of anaerobic organisms that replace normal lactobacilli, causing BV.

Bacterial vaginosis symptoms

    One of the most common symptoms of bacterial vaginosis (BV) is odour, often described as ‘fishy-smelling’. Other symptoms can include:

    • Watery discharge 
    • Greyish white discharge 
    • Worsening of the above symptoms after sex or during your period

    Everyone is different, so you might have BV and not suffer from any symptoms at all. You should also remember that BV is not a sexually transmitted infection and it should not cause any soreness or irritation.

    You should see your doctor if: 

    • You are suffering from BV symptoms for the first time
    • You are pregnant

    Facts about BV

    Canesten pH drop icon

    The natural pH in your vagina is lower than 4.5, which means it is slightly acidic. A pH greater than 4.5 is considered alkaline and can be suggestive of bacterial vaginosis.

    While BV can be mistaken for thrush, they are two different conditions that require a different treatment. When in doubt, you should consult your doctor for a diagnosis or give Canestest a try.
