About yeast infections.
It is estimated that 75% of women will have a yeast infection at some time in their lives. And half of all women will have more than one. Though itchiness is a main symptom, if you've never had a yeast infection before, it's important to see your doctor to get a diagnosis.
Yeast infection causes
Vaginal yeast infections occur when certain internal or external factors change the normal environment of your vagina and trigger an overgrowth of a microscopic fungus. The acidic balance of the vagina can be changed by your period, pregnancy, diabetes, some antibiotics, birth control pills and steroids. Moisture and irritation of the vagina also seem to encourage yeast to grow.
Repeated yeast infections can be triggered by other, less serious, illnesses or physical and mental stress, anything that may lessen your immunity. Bubble baths, vaginal contraceptives, damp or tight-fitting clothing and feminine hygiene products, such as sprays and deodorants, don't cause yeast infections, but they may make you more susceptible.
Risk factors
Some women get mild yeast infections towards the end of their menstrual periods, possibly in response to the body's hormonal changes. You may be at risk if you are taking certain medications, such as antibiotics and steroids, or have uncontrolled diabetes. Hormonal changes, such as those associated with pregnancy, birth control pills and menopause may also contribute to a yeast infection.
