    Thrush or Candidiasis is caused by the overgrowth of yeast-like fungi called Candida. Candida inhabits the vagina, mouth and digestive tract in small numbers and is normally harmless. When the balance of naturally occurring organisms in the vagina is disrupted an overgrowth of Candida can occur. Thrush can develop as a result of the use of antibiotics, oral contraceptives or steroids. It is also more prevalent in those with diabetes, multiple sclerosis, a weakened immune system, a history of allergies or who are pregnant. Thrush does not appear to be sexually transmitted. There are however numerous sexually transmitted infections that can be spread by unprotected oral sex. It is always wise to use condoms. if not you should mention this to your Dr. when you have your routine sexual health screen.
