They are, in fact, one type of vaginal infection, which nearly every female experiences at least once in her lifetime. Yeast infectious are caused by one of the many species of fungus called Candida. These fungi 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. Usually this happens when a change in the delicate balance in a woman's system occurs. Pregnancy, which changes hormone levels, and diabetes, which allows too much sugar in the urine and vagina, can also upset the delicate balance. Other common risk factors for yeast infections include high estrogen contraceptives, immunosuppression, thyroid or endocrine disorders, and corticosteroid therapy. Practice good hygiene and have a gynecological exam every 1-2 years.
