Find out about the symptoms, causes and treatment of thrush.
Thrush is a yeast infection that is caused by a fungus that lives naturally in the body. It’s not a sexually transmitted infection (STI), but it can be passed on during sex.
Anyone can both get thrush but it’s much more common in people with a vagina. It’s estimated that three out of four women will develop it at some point in their lives.
Symptoms of thrush for people with a vagina can include:
Symptoms of thrush for people with a penis can include:
Thrush is a yeast infection caused by fungus that exists naturally in the body. The fungus that causes thrush tends to grow in warm, moist conditions.
With vaginal thrush, it can develop when conditions in the vagina change – such as when taking antibiotics, when hormone changes occur due to pregnancy, when you have diabetes or if your immune system is weak.
Taking antibiotics will cause thrush in about a third of women because they kill off the good bacteria in the vagina.
Thrush can usually be diagnosed by describing your symptoms or being examined at your GP surgery or sexual health clinic such as Brook. Find your nearest using our find a service tool.
You will be asked some questions about your symptoms, whether you’ve had thrush before and whether you’re taking antibiotics for something else.
If you keep experiencing thrush, you may need to provide a swab. The swab looks like a small cotton bud, which is wiped over the affected area. Taking the swab may be slightly uncomfortable but should not be painful.
The swab will be used to see if you have a yeast infection and may also be used to look for a sexually transmitted infection (STI). If you are having recurrent symptoms of thrush the doctor or nurse at the sexual health clinic may suggest that you go and see your GP for further health tests.
Although you can buy treatments for thrush at the chemist, it’s always best to get it diagnosed by a doctor or nurse first; this is because lots of other infections can have similar symptoms and you may not get the right treatment.
Treatment may include a combination of pills, creams or pessaries. A pessary is a pill that you insert into your vagina and dissolves, usually overnight. Cream is applied to the genital area. In men, treatment usually involves a cream that you apply to the area affected.
Some people can get recurrent thrush, while others seem to only have one episode. If you find that you are getting repeated symptoms it is important to go to seek medical advice for further management.
Some thrush treatments can weaken latex condoms, diaphragms and caps. Ask the staff at the clinic or pharmacist for further advice.

Before taking any medication you should always inform the doctor, nurse or pharmacist if you think you may be pregnant. If you are pregnant then you should use the cream and pessaries and not the oral tablets. Thrush is not harmful to you or the baby.
Not an STI but STIs can trigger it.
