Vaginal Thrush

What is vaginal thrush?

Vaginal thrush is a common yeast infection that shifts the delicate balance of your intimate health. It isn't a sexually transmitted infection, but a localised overgrowth of Candida albicans, a fungus that usually lives harmlessly in your body. When the environment changes, the yeast multiplies rapidly, causing the vaginal lining to become inflamed, red, and intensely irritated.

Thrush can strike at any time, though it is more frequent during pregnancy, after taking antibiotics, or during your period when hormone levels shift.

Symptoms of vaginal thrush

Symptoms usually focus on the vulva and vagina and can range from mild annoyance to severe distress. Common signs include a thick, white discharge (often described as looking like cottage cheese), stinging when you urinate, and a "fierce" itch that makes you feel constantly uncomfortable.

Sometimes the inflammation becomes so sharp that the skin around the vagina cracks or swells. If you notice a foul-smelling discharge, experience heavy pelvic pain, or have blisters and sores, it may not be thrush. These can be signs of other infections, and you should seek a medical review to ensure you get the right diagnosis.

What triggers vaginal thrush?

The "trigger" for thrush is anything that disrupts the natural, slightly acidic balance of your vagina. When the "good" bacteria (lactobacilli) are suppressed, the yeast takes over.

Common triggers include using harsh soaps or "intimate" perfumed washes, wearing tight synthetic underwear that traps heat and moisture, high blood sugar levels (uncontrolled diabetes), and recent courses of antibiotics that kill off the protective bacteria in your system.

Managing vaginal thrush and using treatments

Thrush is rarely dangerous, but it is incredibly stubborn if left untreated. The secret to winning the fight is to clear the internal infection while simultaneously soothing the external skin.

Most plans to fight vaginal thrush rely on two main types of antifungal treatment:

First, you use an internal treatment (like a Clotrimazole pessary or a Fluconazole oral capsule). The pessary is a tablet you insert high into the vagina to kill the yeast at the source, while the oral capsule works through your bloodstream to reach the infection from the inside out.

Second, you use an external antifungal cream. This doesn't clear the internal infection, but it dives into the irritated skin on the outside to stop the itching, reduce the redness, and provide immediate cooling relief while the internal treatment does the heavy lifting.
