What are Candida or "yeast" infections?
Yeast infections of the vagina are what most women think of when they hear the term "vaginitis." They are caused by one of the many species of fungus called Candida. Candida normally live in small numbers in the vagina as well as in the mouth and digestive tract of both men and women.Yeast infections produce a thick, white vaginal discharge with the consistency of cottage cheese. Although the discharge can be somewhat watery, it is odorless. Yeast infections usually cause the vagina and the vulva to be very itchy and red.
Since yeast is normal in a women's vagina, what makes it cause an infection? Usually this happens when a change in the delicate balance in a woman's system occurs. For example, a woman may take an antibiotic to treat a urinary tract infection and the antibiotic kills her "friendly" bacteria that normally keep the yeast in balance; as a result the yeast overgrows and causes the infection. Other factors which can upset the delicate balance include pregnancy which changes hormone levels and diabetes which allows too much sugar in the urine and vagina.
