Vaginal thrush is an overgrowth of a yeast — most often Candida albicans — in and around the vagina and vulva. You’ll see it called several things: vulvovaginal candidiasis is the medical term, vaginal yeast infection is common usage, and thrush is what most people say in Australia. They all mean the same condition.
Candida lives harmlessly in the vagina in small numbers much of the time. Thrush happens when the balance shifts and it multiplies. It’s extremely common — around three in four women will have at least one episode in their lifetime, and many will have more than one. It’s uncomfortable and irritating, but it isn’t dangerous, and it responds well to treatment.
Thrush is not a sexually transmitted infection. It’s an overgrowth of a yeast that’s already present in your own body, and you can get it without ever having been sexually active. A diagnosis of thrush says nothing about your partner, your relationship, or your sexual history. Sex can sometimes trigger an episode through friction or irritation, but that isn’t the same as it being sexually transmitted, and routine treatment of partners is not needed. If you have symptoms and you’re worried about an STI, that’s a separate question worth answering with a test — because STI and thrush symptoms overlap.
Thrush Symptoms — and What Else It Might Be
The hallmark symptom of thrush is itch. If itching isn’t part of the picture, thrush becomes less likely. Typical symptoms include:
Intense itching of the vulva and vagina
Soreness, burning or stinging
Thick, white discharge, often described as looking like cottage cheese — and usually not smelly
Redness and swelling of the vulva
Stinging when passing urine, especially as it touches irritated skin
Discomfort or pain during sex
Sometimes small cracks or splits in the skin
Notably, thrush discharge doesn’t usually have a strong odour. A fishy or unpleasant smell points away from thrush and towards bacterial vaginosis or trichomoniasis instead — one of the most useful distinctions to know.
What triggers thrush?
Thrush usually happens when something disturbs the normal balance in the vagina. Common triggers include antibiotics (probably the most common, as they disrupt the protective bacteria), pregnancy and hormonal changes, diabetes (particularly when blood sugar is poorly controlled), a weakened immune system or immune-suppressing treatment, irritants such as soaps, bubble baths, douches and perfumed products, and tight or non-breathable clothing. Often, though, there’s no identifiable trigger at all. Getting thrush doesn’t mean you’ve done anything wrong or that your hygiene is poor — in fact, over-washing and using vaginal cleaning products makes it more likely, not less.
Is it actually thrush? Often, it isn’t
Here’s the single most useful thing on this page: self-diagnosed thrush is frequently something else. Studies consistently find that a large proportion of women who buy over-the-counter thrush treatment don’t actually have thrush. The most common alternatives are bacterial vaginosis and trichomoniasis, and neither responds to thrush treatment.

This table is a guide, not a diagnosis. The symptoms overlap enough that even experienced clinicians often can’t tell them apart reliably without testing — and you can have more than one at the same time. If you’ve treated yourself for thrush and it hasn’t worked, that’s a strong signal to get tested rather than to try again.
Testing for Thrush
Testing is quick and simple. It’s usually a vaginal swab, which can often be self-collected in private rather than needing an examination. The swab is sent to the laboratory, where it can confirm whether candida is present, identify the species, and simultaneously check for bacterial vaginosis and trichomoniasis — the two conditions most often mistaken for thrush. If you’re sexually active and have symptoms, STI testing can usually be done from the same sample, closing off the other possibilities in one step. Results are typically available within a few days.
When testing matters most
Not every episode of thrush needs testing. If you’ve had it before, recognise it clearly, and it responds to treatment, that’s reasonable. But you should get tested if:
It’s your first episode and you’ve never had a confirmed diagnosis.
Treatment hasn’t worked, or symptoms return quickly afterwards.
You’re getting recurrent episodes (four or more in a year).
Your discharge is smelly, grey, green or frothy — that isn’t typical thrush.
You have any risk of an STI, or a partner has been diagnosed with one.
You’re pregnant, or you have any bleeding, pelvic pain or fever.
How testing works with Clinic365
A Specialist GP reviews your symptoms over a quick phone call and sends your pathology referral by SMS. You walk into any pathology lab Australia-wide — no appointment needed — and results come back by SMS, usually in 2-3 days. Because the swab can check for thrush, BV and trichomoniasis together, you get the right diagnosis and the right treatment rather than guessing. You can also add a full STI test if there’s any chance of an infection.
Thrush Treatment and Recurrent Thrush
Thrush is treated with antifungal treatment, and most uncomplicated episodes clear quickly. Treatment comes in two broad forms: a topical antifungal cream or pessary used vaginally, and an oral antifungal treatment taken by mouth. Both are effective, and the choice usually comes down to preference, symptom pattern, and whether you’re pregnant — topical treatment is preferred in pregnancy, and oral treatment is generally avoided. Symptoms typically start improving within a couple of days. Complete the full course even once the itch settles, a soothing barrier cream can ease external soreness while the treatment works, and note that some vaginal treatments can weaken condoms and diaphragms — check with your clinician or pharmacist. If you’re pregnant, or might be, tell your clinician before starting any treatment.
Recurrent thrush
Recurrent vulvovaginal candidiasis is usually defined as four or more episodes in twelve months. It’s genuinely miserable, and more common than people realise — but it’s a different problem from a one-off episode and needs a different approach. Repeatedly buying single-dose treatments rarely solves it. What’s usually needed is confirming the diagnosis with a swab (because recurrent “thrush” that isn’t thrush is common — persistent vulval itching can turn out to be a skin condition such as lichen sclerosus rather than a yeast infection), checking for an underlying contributor such as undiagnosed diabetes, identifying the candida species — since some respond poorly to standard treatment — and then a longer induction-and-maintenance regimen over several months rather than a single dose. If you’re getting thrush again and again, don’t keep self-treating: see a clinician and get a swab.
When treatment isn’t working
If treatment hasn’t helped, resist the urge to simply repeat it. The likely explanations are that it isn’t thrush (bacterial vaginosis, trichomoniasis or an STI may be the real cause), that it’s a different candida species that doesn’t respond to standard antifungals, that it’s a skin condition such as eczema, dermatitis or lichen sclerosus (which can all cause vulval itch and be misread as persistent thrush), that there’s an ongoing irritant keeping the skin inflamed, or that there’s an underlying contributor such as poorly controlled diabetes. The right next step is a swab and a proper review, not another course of the same treatment.
See a clinician promptly if you have fever or feel generally unwell, pelvic or lower abdominal pain, unusual vaginal bleeding (including bleeding after sex), blisters, ulcers or sores, or symptoms during pregnancy. These are not features of simple thrush and need proper assessment.
Prevention and Self-Care
You can reduce your chances of thrush with a few simple measures — and, importantly, by stopping some things people commonly do that make it worse:
Don’t douche or use vaginal washes. The vagina cleans itself; these products disturb the balance and increase thrush and BV.
Avoid perfumed soaps, bubble baths and feminine hygiene products. Wash the vulva with water or a plain non-soap cleanser.
Wear breathable underwear and avoid staying in damp or tight clothing for long periods.
Change out of wet swimwear or gym gear promptly.
If you have diabetes, good blood sugar control reduces episodes.
Probiotics and dietary changes are often suggested online; the evidence for them is limited, and they’re no substitute for treatment or for finding out what’s actually causing your symptoms.
Frequently asked questions
Vaginal thrush is an overgrowth of a yeast, usually Candida albicans, in the vagina and vulva. It’s also called vulvovaginal candidiasis or a vaginal yeast infection — all the same condition. It’s very common, with around three in four women having at least one episode in their lifetime. It’s uncomfortable but not dangerous, and treats well.
No. Thrush is an overgrowth of a yeast already present in your body, and you can get it without ever having been sexually active. It says nothing about your partner or sexual history. Sex can sometimes trigger an episode through irritation, but partners don’t routinely need treatment.
The hallmark is intense itching of the vulva and vagina, along with soreness or burning, redness and swelling, and a thick white discharge often compared to cottage cheese. The discharge usually has no strong smell. Stinging when passing urine and discomfort during sex are also common. If itch isn’t present, thrush is less likely.
You often can’t tell reliably. Thrush is itchy with thick odourless discharge; bacterial vaginosis typically has thin grey discharge with a fishy smell and little itch; trichomoniasis often has frothy yellow-green discharge. But symptoms overlap, you can have more than one at once, and even clinicians often need a swab to be sure.
Usually with a vaginal swab, which can often be self-collected in private rather than requiring an examination. The lab can confirm candida, identify the species, and check for bacterial vaginosis and trichomoniasis at the same time. If you’re sexually active with symptoms, STI testing can typically be arranged from the same visit.
With antifungal treatment — either a cream or pessary used vaginally, or an oral antifungal. Both work well, and the choice depends on preference, symptom severity and pregnancy status. Topical treatment is preferred in pregnancy. Complete the full course even once symptoms settle. A clinician can advise which suits you.
Recurrent thrush means four or more episodes in a year, and it needs a different approach from a one-off. Repeated single-dose treatments rarely fix it. You need a swab to confirm the diagnosis (recurrent thrush often isn’t thrush), a check for contributors like diabetes, species identification, and a longer maintenance regimen over several months.
Don’t just repeat it. It may not be thrush at all — bacterial vaginosis, trichomoniasis or an STI could be the cause. It could also be a candida species that resists standard treatment, a skin condition like eczema or lichen sclerosus, an ongoing irritant, or undiagnosed diabetes. Get a swab and a proper review.
Not routinely. Thrush isn’t sexually transmitted, so partners don’t usually need treating. Occasionally a male partner develops a rash or irritation after sex with someone who has thrush, and if so, that can be treated. Otherwise, treatment of partners doesn’t reduce your risk of getting thrush again.
Yes, but the treatment differs. Topical antifungal treatment is used in pregnancy, while oral antifungal treatment is generally avoided. Thrush is more common during pregnancy due to hormonal changes. Always tell your clinician if you are or might be pregnant so the right treatment is chosen for you.
Antibiotics are the most common trigger, as they disturb the protective bacteria. Others include pregnancy, hormonal changes, diabetes, a weakened immune system, irritants like perfumed soaps and douches, and tight or damp clothing. Often there’s no identifiable trigger. Getting thrush doesn’t mean poor hygiene — over-washing actually makes it more likely.
Somewhat. Don’t douche or use vaginal washes — they disturb the natural balance and increase thrush and BV. Avoid perfumed soaps and feminine hygiene products, wash the vulva with water only, wear breathable underwear, and change out of damp clothing promptly. If you have diabetes, good blood sugar control reduces episodes.
See a clinician if it’s your first episode, if treatment hasn’t worked, if symptoms keep returning, if your discharge is smelly, grey, green or frothy, if you’re pregnant, or if there’s any chance of an STI. Seek prompt care for fever, pelvic pain, unusual bleeding, or blisters or sores — these aren’t features of simple thrush.
