Thrush is an infection that is caused by a yeast fungus. It is not a sexually transmitted infection but can sometimes develop after you have had sex and it is possible for thrush to spread during sex.

Many cases of thrush develop in men and women who are not sexually active. If you get thrush from your partner, it does not mean that they have been having sex with other people.

Often the cause of thrush is unknown. If a person has a damaged immune system or diabetes, they may be more likely to get thrush.

Thrush can develop in and around the vagina in women, and on the head of the penis and under the foreskin in men. It often causes itching, redness and soreness, as well as causing a discharge.

Tests and treatment

You can go to your GP surgery or a sexual health clinic for an examination and a simple swab test if you think you may have thrush.

A pharmacist can also provide over the counter medication. Thrush infection is usually easy to treat with antifungal medication - taken by mouth or as a vaginal pessary for women, and as a cream for men.

However, sometimes it can reoccur and some people are prone to repeated infections.
