Thrush is an often itchy and uncomfortable infection of the vagina and/or vulva (vulvovagina) caused by yeasts.
Vulvovaginal thrush is usually caused by an overgrowth of the yeast (fungus) called Candida albicans. This occurs when the pH of the vagina is altered or there are changes to your sex hormones (i.e. during pregnancy, when using hormonal contraception).
- Hormonal contraceptives (i.e. the pill, implant, injection, ring or hormonal coil)
- Uncontrolled diabetes
- Antibiotic use
- Using feminine hygiene products
- Synthetic clothing
- Sex (this can trigger thrush, but thrush is not a sexually transmitted disease)
- Hormone replacement therapy
- HIV or a weakened immune system
- Vulvovaginal itching
- Soreness, or irritation of the vulvovagina
- Redness of the vaginal area
- Thick white vaginal discharge (typically described as looking like cottage cheese)
- Pain when urinating
- Pain when having sex
- Symptoms are sometimes worse the week before a period
- Over the counter antifungal medications to treat the infection.
When to speak to a doctor
Thrush can often be initially managed by speaking to a pharmacist or purchasing thrush cream over the counter.
It is important to speak to a doctor if you are:
- Not improving after using over the counter treatment
- Experiencing severe pain
- The vulvovaginal skin is raw or cracked
- Having smelly vaginal discharge or discharge you are worried about
- Worried you might have a sexually transmitted infection
