Thread: Why are women on BC more likely to have yeast infections?

With birth control the addition of the estrogen component from bcp can alter the environment of the vagina. This can be pH wise, lubrication wise, generally speaking it just makes it a more moist and inviting environment for yeast to grow. Yeast is normally present at regular flora levels in the vagina and the gastro tract but when conditions are right it will overgrow and cause the irritating symptoms of a yeast infection. Not all women are affected in the same way by the altered estrogen levels so it not to say that taking bcp will absolutely cause a yeast infection, simply not the case.

Condoms will not necessarily increase the odds of contracting a yeast infection because they will generally dry the vagina out due to the latex, however if too much irritation occurs because of the condom then a yeast infection can occur because that area will be filled with blood (the irritation) and hence a more 'suitable' environment can occur. Yeast infections are not limited to simply having sex a certain way. A woman can be completely void of sex her entire life and can still get a yeast infection due to improper hygiene or soap irritations or wearing tight fitting underwear causing a more moist vaginal environment.
