Thrush, or candidiasis, is caused by a yeast organism irritating the mucous membrane of the genitals.
Thrush has different names — depending on the genitals it affects. If you get thrush under the foreskin of your penis, it’s called balanitis. When thrush is around your vulva, it’s called vulvitus. Inside your vagina, thrush is called vaginitis. You can also get thrush in your throat.
Thrush, or candidiasis, is not a sexually transmissible infection (STI).
You are more at risk of thrush if you:
- Are on antibiotics or steroid medication
- Are hapū
- Have low immunity
- Experience vaginal dryness during sex
- Use soap or fragrances on or around your genitals
