A woman is more likely to get a yeast infection during pregnancy, suggests the American Pregnancy Association. The symptoms include an increase in thin, white discharge. Some itching or inflammation can develop as well. The cause of yeast infections in pregnancy are generally the same as in women who aren't pregnant, but hormones can increase the likelihood of an infection.
Hormones
Various hormones, such as progesterone, increase in pregnancy. These hormones can increase vaginal discharge and the chemical consistency of the secretions. Like other yeast infection causes, any sort of imbalance of organisms can allow fungi to overproduce causing an infection.
Antibiotics
Antibiotics can kill both good and bad bacteria in the body, which allows yeast to overgrow. This can be a temporary problem but it can still lead to a vaginal yeast infection. The American Pregnancy Association points out that eating yogurt or other probiotic products can help restore the normal balance to the vagina.
Ideal Environment
Yeast thrive in moist and warm environments. During pregnancy a woman experiences an increase in vaginal discharge. The American Pregnancy Association explains that these vaginal secretions are higher in sugar, which can result in too much fungus and an overall imbalance of organisms in the vagina. Various techniques can be attempted to control the moisture in the vaginal area. This includes wearing loose, cotton undergarments and keeping the area as dry as possible. Douching and wiping from back to front can increase the risk of yeast infections and should be avoided.
Intercourse
The American Congress of Obstetricians and Gynecologists points out that intercourse can lead to a vaginal yeast infection. This is often the result of the introduction of other organisms to the vagina that cause an imbalance of existing bacteria and fungi. Washing after intercourse can reduce the risk of infection.
