Thrush in pregnancy: what you can and can't do

Qu'est-ce que le muguet ?

It's normal for germs to live on the skin around the vagina. One of these germs, a yeast-like fungus called Candida albicans, can cause la mycose vaginale - a common and very treatable infection.

Symptoms of thrush include:

• Itching, irritation and swelling around your vagina.

• Soreness when you pee.

• Soreness during sex.

• A white, odourless cottage cheese-like discharge.

Jo Parkinton is a resident midwife at Lansinoh with more than 28 years' experience in the NHS says: "During la grossesse, fluctuations in your hormones can affect the pH balance in the vagina. This can encourage the yeast that causes thrush to grow."

The more candida yeast you have, the more likely you are to develop a thrush infection. Vaginal thrush can sometimes be passed on during sex but is not considered a sexually transmitted infection (STI).

Thrush is very common among women - 15 in 20 women develop thrush at least once, while one in 20 women experience repeated infections¹. It's even more likely to occur during pregnancy, especially during the third trimester, when the biggest hormonal changes take place. Breastfeeding can also cause mother and baby to develop different types of thrush.

According to midwife Jo, thrush is a harmless yeast infection that bears no threat to you or your unborn baby. This is a mild infection that doesn't spread to your womb, nor can it damage your vagina long-term. However, you should treat thrush, and be careful to use the treatments suitable for pregnancy.

Safe treatments during pregnancy

During pregnancy, it's always best to check with your midwife, doctor, or pharmacist before trying any over-the-counter treatments. When it comes to thrush, there are some you need to avoid. Jana Abelovska, superintendent pharmacist at Click Pharmacy, says:

"Effective treatments include clotrimazole - brand name Canesten - in either a cream or a type of tablet called a pessary that is inserted into the vagina."

You can use these safely during pregnancy, but you should always complete the recommended course.

Other ways to keep thrush under control

Midwife Jo also shares things you can do to feel more comfortable and help keep thrush under control:

Having thrush during pregnancy is generally nothing to worry about and won't harm your unborn child. However, this infection needs to be treated. Here's why:

• If you have thrush when your baby is born, you could pass the infection to your baby during the delivery - if you are having a vaginal delivery.

• The symptoms can be irritating and painful.

Most women will have had thrush and know the symptoms but if vous n'êtes uncertain about whether vous have thrush or not, seek advice from vous midwife ou doctor first before trying any treatment. If you have tried treatment and it is not getting better, you need to see a doctor as
around one in 10 cases of thrush are caused by other strains of the candida fungus, and these may not be so easily treated. The doctor can also check for other possible causes.
