The yeast responsible for causing thrush is naturally present on the body and likes moist, warm conditions. It normally starts to overgrow and infects the vagina due to a change in the vaginal environment. Some of the reasons that may change the vaginal environment making thrush more likely to occur, include:

  • irritated or damaged vaginal skin (which can occur due sexual intercourse)
  • having poorly controlled diabetes
  • having a weakened immune system (for example, because of HIV or chemotherapy)
  • going through the menopause
  • being pregnant

taking long-term antibiotics
