What is Thrush?

While not many talk about it, thrush will affect 3 out of 4 women at least once in their lives1. Thrush is a common condition with a range of simple treatment solutions.

Getting thrush for the first time can be unpleasant, confusing, and stressful. It is common to think that thrush is associated with something more serious or is a result of "something you've done". This is NOT the case. In fact, thrush is simply the result of a change in pH balance in the vagina.

Thrush is a yeast infection of the vagina caused by Candida albicans. Most naturally occurring yeasts in the vagina are harmless however an overgrowth of Candida albicans can lead to the unpleasant symptoms associated with thrush. Thrush can develop following changes in lifestyle, health or habit.

Common causes of thrush:

  • Antibiotics can destroy friendly bacteria that keeps vaginal yeast under control.
  • Hormone changes brought on by pregnancy, the pill, or a period.
  • Poor diet, lack of sleep, or stress.
  • A weak immune system brought on by illness.
  • Over-use of chemical deodorants, perfumed bodywash or sprays near the vagina.
  • Tight or synthetic clothing creating a warm, moist environment.
