Thrush is an infection caused by a yeast called Candida. Candida is found on the body naturally but is normally kept at low levels by the immune system and other bacteria. However, on occasion levels of Candida are allowed to rise and cause infection.
How you can avoid thrush in the future: Wear cotton briefs, stockings and loose-fitting clothes rather than tight synthetic clothing. Wash regularly but do not wash and dry yourself too harshly. Avoid perfumed soaps, bath additives and vaginal deodorants. Change your tampon frequently as a blood-soaked tampon can provide ideal conditions for yeast growth.
Sexual intercourse can damage delicate tissue and aggravate thrush. Vaginal thrush is not classed as a VD or STD but may be passed on to your partner through intercourse. If your attack of thrush was successfully treated, but keeps coming back, your partner may need to treat his own thrush. If you are unsure why your thrush keeps coming back, or are unsure if your partner has thrush, you or your partner should see a doctor.
