Vaginal Candidiasis

Medically reviewed by Joel Nyandigira Updated August 2026

Overview


Vaginal candidiasis, commonly known as a yeast infection or vaginal thrush, is a very common condition caused by overgrowth of Candida yeast in the vagina. It is not a sexually transmitted infection, though sexual activity can occasionally trigger it.

Symptoms of Vaginal Candidiasis


  • Intense vaginal itching
  • Thick, white, "cottage cheese"-like vaginal discharge, usually without a strong odour
  • Redness and soreness of the vaginal area
  • Discomfort during urination or sexual intercourse

What Causes Vaginal Candidiasis?


  • Caused by overgrowth of Candida yeast, which is normally present in small amounts in the vagina.
  • Risk is increased by antibiotic use (which disrupts normal protective bacteria), pregnancy, poorly controlled diabetes, and a weakened immune system.
  • Tight, non-breathable clothing and prolonged moisture can also contribute.

How is Vaginal Candidiasis Diagnosed?


  • Usually diagnosed clinically based on the characteristic itching and discharge.
  • Microscopic examination of vaginal discharge, where available, can confirm the diagnosis, particularly for recurrent or uncertain cases.

Treatment for Vaginal Candidiasis


Treatment is with an antifungal medicine, either as a vaginal cream or pessary (such as clotrimazole) or a single oral dose (such as fluconazole), both of which are highly effective.

Symptoms usually improve within a few days of starting treatment.

Recurrent infections (several episodes within a year) may need a longer treatment course and evaluation for contributing factors, such as poorly controlled diabetes.

Pregnant women should use a topical rather than oral antifungal treatment, as oral antifungal medicine is generally avoided in pregnancy.

How to Prevent Vaginal Candidiasis


  • Wear breathable, cotton underwear and avoid tight-fitting clothing.
  • Avoid vaginal douching and scented feminine hygiene products.
  • Change out of wet clothing, such as swimwear, promptly.
  • Manage underlying conditions such as diabetes well, as poor control increases risk.
