Causes, incidence, and risk factors
Most women have a vaginal yeast infection at some time. Candida albicans is a common type of fungus. It is often found in small amounts in the vagina, mouth, digestive tract, and on the skin. Usually it does not cause disease or symptoms.

Having many vaginal yeast infections may be a sign of other health problems. Other vaginal infections and discharges can be mistaken for a vaginal yeast infection.
Signs and tests
A pelvic examination will be done. It may show swelling and redness of the skin of the vulva, in the vagina, and on the cervix. The health care provider may find dry, white spots on the vaginal wall. There may be cracks in the skin of the vulva.
Sometimes, a culture is taken when the infection does not improve with treatment or comes back many times.

Chronic or recurrent infections may occur if you do not get the proper treatment or have an underlying medical condition. It is important for your doctor to check you for diseases that can lead to yeast infections, such as diabetes.
Secondary infection may occur. A lot of scratching may cause the area to crack, making you more likely to get an infection.
Repeat infections that occur immediately after treatment, or a yeast infection that does not respond to any treatment, may be an early sign of HIV.
